Nausea and vomiting associate with increasing maternal androgen levels in otherwise uncomplicated pregnancies

BACKGROUND: The objective of the present study was to investigate the hypothesis that maternal androgen levels associate with nausea and vomiting in otherwise uncomplicated pregnancies. METHODS: One hundred and twenty-nine women with uncomplicated pregnancies, reported nausea and vomiting in weeks 17, 25, 33, 37, and when admitted for delivery. Maternal levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), testosterone, and sex hormone binding globulin (SHBG) were measured and the free testosterone index calculated in weeks 17 and 33 of pregnancy. RESULTS: Maternal levels of androstenedione and DHEAS associated positively with nausea and vomiting in week 17. In week 33, testosterone and DHEAS associated positively with nausea and vomiting, as well as androstenedione. A calculated emesis score associated positively with increasing average levels of both androstenedione and testosterone during pregnancy, as well as the free testosterone index. CONCLUSIONS: Nausea and vomiting associate with increasing maternal androgen levels during otherwise uncomplicated pregnancies. Whether androgens are causally related to emesis gravidarum remains unknown.     

Effect of oral micronized progesterone on androgen levels in women with polycystic ovary syndrome

Objective: To determine whether the use of oral micronized progesterone (OMP) to induce withdrawal bleeding in women suspected of having polycystic ovary syndrome (PCOS) alters circulating androgen levels.

Design: Prospective clinical trial.

Setting: Academic medical center.

Patient(s): Eight reproductive-aged women with PCOS.

Intervention(s): Blood was sampled before (week 0) and weekly after (weeks 1 to 4) the administration of OMP (Prometrium, Solvay Pharmaceuticals, Marietta, GA), 100 mg in the morning and 200 mg before bedtime for 7 days.

Main Outcome Measure(s): The levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), and androstenedione (A4) were determined in the blood samples.

Result(s): In seven of the eight women studied, menstrual cycle intervals were >3 months, while one was eumenorrheic; six of the eight women had hirsutism (modified Ferriman-Gallwey score >7). Mean age was 28.9 ± 10.4 years and mean body mass index was 33.9 ± 4.7 kg/m². The mean values of TT, FT, SHBG, DHEAS, A4, and 17-OHP did not change with OMP administration. However, a higher 17-OHP level was observable at the completion of OMP administration (week 2).

Conclusion(s): We conclude that the administration of OMP (100 mg in the morning and 200 mg before bedtime for 7 days) to induce withdrawal bleeding in women with PCOS does not significantly alter circulating androgen or 17-OHP levels, and can be used to time blood sampling in these patients.     

Plasma levels of C-19 steroids and 5 alpha-reduced steroid glucuronides in hyperandrogenic and idiopathic hirsute women

In the present study, the authors measured the plasma levels of unconjugated and glucuronide (G) derivatives of C-19 steroids in hirsute women divided into two groups, depending upon their dehydroepiandrosterone sulfate (DHEAS). This quite restrictive classification was the result of an arbitrary decision of the authors, who wanted to focus interpretation of their data on DHEAS, the well-known adrenal androgen. In the hyperandrogenic hirsute woman (HH), the DHEAS levels were higher than 3.0 micrograms/ml; in idiopathic hirsute women (IH), values of DHEAS were comparable to those observed in normal women (1.2 to 2.5 micrograms/ml). In the HH group, the levels of dehydroepiandrosterone, androstenedione, androst-5-ene-3 beta,17 beta-diol (delta 5-diol), testosterone, dihydrotestosterone (DHT), androstane-3 alpha, 17 beta-diol (3 alpha-diol), androstane-3 beta,17 beta-diol (3 beta-diol), androsterone (ADT), DHTG, 3 alpha-diol-G, 3 beta-diol-G, and ADTG were higher than the normal range whereas, in the IH group, only delta 5-diol, DHT, 3 beta-diol-G and ADTG were elevated. These data are compatible with the hypothesis that the plasma levels of steroid G represent the peripheral formation of androgen in target tissues. Because the pattern of androgen metabolism is most probably changed in many cases of hirsutism, these data suggest that for research purposes, it would be preferable to measure 3 beta-diol-G and ADTG in addition to 3 alpha-diol-G in order to gain additional information concerning androgen metabolites in this disorder.     

Serum insulin-like growth factors in normal pregnancy and in pregnancies complicated by preeclampsia

BACKGROUND: Lower levels of insulin-like growth factor I (IGF-I) have been shown to be associated with preeclampsia and also with a reduced risk of breast cancer later in life. Lower levels of IGF before clinical signs of preeclampsia could be one possible mechanism in the etiology of preeclampsia as well as for the reduced risk of breast cancer associated with preeclampsia. We have prospectively investigated maternal serum levels of IGF-I, IGF-II, and the main binding protein insulin-like growth factor binding protein 3 (IGFBP-3) in women with and without preeclampsia. METHODS: We used maternal serum samples from a Swedish-Norwegian cohort study obtained in the 17th and 33rd gestational week from 30 women who subsequently developed preeclampsia and 128 women who did not develop preeclampsia. RESULTS: There were no significant differences in serum concentrations IGF-I and IGFBP-3 in the 17th or the 33rd week of gestation between women who developed preeclampsia or not. Compared with nonpreeclamptic women, preeclamptic women had significantly higher serum levels of IGF-II in week 33, but there was no difference in week 17. CONCLUSION: In women who developed preeclampsia, we found no support for the hypothesis that the disease was preceded by lower serum levels of IGF-I and IGF-II, or higher serum levels of IGFBP-3. However, among women who later developed preeclampsia, serum levels of IGF-II were significantly higher in the 33rd gestational week.     

Assessment of the adrenal-ovarian contribution by short-term dexamethasone and ACTH tests in hyperandrogenized patients.

Fifty-four hyperandrogenized women were studied to evaluate the importance of the adrenal or ovarian contribution to androgen secretion. Forty-six had the polycystic ovarian (PCOD) syndrome. Eight normal women represented a control group. The endocrine study was performed during the follicular phase. The plasma samples were collected at 7.00 am (A1) and at 11.00 pm (A3). Dexamethasone 2 mg was administered orally at 11.30 pm and blood samples were collected the day after, at 7.00 am (B). The adrenocorticotropic hormone (ACTH) was injected, 250 micrograms i.v. and samples were collected after 60 min. Cortisol dehydroepiandrosterone-sulfate (DHEAS), androstenedione, testosterone and 17-hydroxyprogesterone (17OHP) were measured. The hyperandrogenized patients had A1 androgen levels higher than the controls (p less than 0.01). 17OHP and androstenedione A3 values showed a cortisol-related decrease. After dexamethasone, androgen levels, since DHEAS, were normalized in all patients. We found that baseline androgen levels and circadian and dexamethasone-inhibited amounts were strongly correlated (p less than 0.01). The ACTH test revealed five cases of enzymatic adrenal deficiencies. Moreover, the amplitude of the response of 17OHP and androstenedione to ACTH is predictable in relation to both circadian and dexamethasone-inhibited amounts (p less than 0.01). In conclusion, our study confirms and makes quantifiable the importance of the adrenal contribution to androgen secretion in hyperandrogenized patients. The ACTH test is important for detecting the presence of mild enzymatic adrenal defects.     

Correlation of maternal androgens in early and late pregnancy. A correlation with fetal size and sex

In the course of prospective investigations blood was withdrawn for steroid analysis in 50 gravidae between 12th and 16th and between 26th and 30th week of gestation. The levels of androstenedione, testosterone, dehydroepiandrosterone sulfate, 17-hydroxyprogesterone and sex hormone binding globuline were determined by radioimmuno-assay evaluating a possible correlation between the androgen values and growth retardation or the sex of the fetus. Neither during the early nor during the late period of pregnancy significant differences concerning the androgen levels could be detected among both sexes. Worth mentioning is the significant decrease of the DHEA-S levels during the late period of gestation, which occurred in both groups, whereas the androstenedione, testosterone and especially the 17-OH-P levels showed a significant increase. The SHBG values almost did not change at all.     

Human chorionic gonadotropin and testosterone in normal and preeclamptic pregnancies in relation to fetal sex

OBJECTIVE: The aim of the present study was to evaluate the effects of fetal gender on serum human chorionic gonadotropin (hCG) and testosterone in normotensive and preeclamptic pregnancies. METHODS: The study consisted of 137 women with singleton pregnancies in the third trimester. Seventy-three pregnancies were uncomplicated; among those were 35 male and 38 female fetuses. Sixty-four pregnancies were complicated by preeclampsia; among those were 33 male and 31 female fetuses. Human chorionic gonadotropin and total testosterone were measured in maternal peripheral blood. RESULTS: In male-bearing pregnancies, maternal hCG and testosterone serum levels were significantly higher in preeclamptic than normotensive mothers (P <.001). In female-bearing pregnancies, testosterone levels were significantly higher in preeclamptic than normotensive mothers (P <.001), whereas the hCG levels were not significantly different. Male-bearing preeclamptic women had significantly higher testosterone levels than female-bearing preeclamptic women (P <.02), whereas the hCG levels were not significantly different. In uncomplicated pregnancies the hCG levels were significantly higher in female-bearing than in male-bearing mothers (P <.005), whereas the testosterone levels were not significantly different. CONCLUSION: In preeclamptic pregnancies with male fetuses, the maternal serum hCG levels were significantly higher than in uncomplicated pregnancies. Total testosterone levels were significantly higher in pregnancies with either gender and significantly higher in male-bearing than in female-bearing pregnancies. This may indicate an androgen influence on the pathophysiologic mechanism of preeclampsia.     

Recombinant follicle-stimulating hormone stimulates ovarian androgen synthesis in down-regulated ovulatory women.

In order to study androgen secretion during controlled ovarian hyperstimulation for in-vitro fertilization-embryo transfer, an open randomized study comparing the response to recombinant or urinary follicle-stimulating hormone (FSH) in down-regulated cycles was performed. During FSH administration significant increases in testosterone, androstenedione and dehydroepiandrosterone sulfate (DHEAS) levels were observed. During the same period a slight decrease in luteinizing hormone (LH) levels was seen. At all times during the stimulation period a significant correlation between estradiol and testosterone or androstenedione levels was observed. We conclude that FSH, through granulosa derived paracrine factors, initiates thecal androgen synthesis and secretion.     

Differential effects on the androgen status of postmenopausal women treated with tibolone and continuous combined estradiol and norethindrone acetate replacement therapy

OBJECTIVE: To determine serum parameters reflective of androgen status in postmenopausal women using two types of hormone replacement therapy (HRT). DESIGN: Randomized, double-blind, prospective 1-year trial of two oral HRT regimens. SETTING: University hospital, department of obstetrics and gynecology, menopause clinic. PATIENT(S): 100 postmenopausal women > or = 45 years. INTERVENTION(S): Daily use of the progestogen tibolone (2.5 mg; n = 50) or continuous combined 17-beta-estradiol (2 mg) and norethindrone acetate (E+NA, 1 mg; n = 50). MAIN OUTCOME MEASURE(S): Measurements of total testosterone (total T), dehydroepiandrosterone sulfate (DHEAS), androstenedione (A), FSH, and sex-hormone-binding globulin (SHBG), and calculations of free testosterone (free T). Assessment of changes from baseline within and between groups after 6 and 12 months. RESULT(S): We found significant differences (% changes) in the tibolone group compared to baseline within the groups after both 6 and 12 months, respectively. Levels of free T doubled, total T decreased slightly, and SHBG decreased by half; DHEAS increased by approximately 20%; and FSH decreased. In the E+NA group, levels of free T, total T, androstenedione, and FSH all decreased, and SHBG increased. Pre-trial levels of DHEAS, A, and total T were significantly higher in the E+NA group. Between groups throughout the study, the changes from baseline were significant due to the different extent of FSH reduction, and opposite changes of free T, SHBG, and DHEAS. CONCLUSION(S): Both regimens modify plasma androgens, DHEAS, and SHBG differently. Tibolone decreased the levels of SHBG, and substantially increased free T and to a lesser extent increased DHEAS; this may reflect a modification of adrenal androgen production. Continuous combined estradiol and norethindrone acetate HRT suppressed the peripheral plasma androgens mediated by increased levels of SHBG.     

联合LC-MS和化学发光免疫法分析不同类型PCOS的雄激素水平

目的:利用液相色谱-质谱联用(LC-MS)方法和化学发光免疫分析法测定不同临床类型PCOS患者的血清雄激素水平,分析中国PCOS女性的高雄激素血症的生化特点。方法:纳入有排卵障碍和多囊卵巢的PCOS患者149例,根据血清睾酮(T)和硫酸脱氢表雄酮(DHEAS)值及F-G多毛评分情况分为两组:高雄组55例,非高雄组94例。同期选取输卵管性不孕患者82例作为对照组。化学发光法测定性激素结合球蛋白(SHBG)水平,计算游离雄激素指数(FTI)。LC-MS法测定各组血清睾酮、雄烯二酮(AD)和脱氢表雄酮(DHEA)。结果:高雄组的血清T水平及FTI值显著高于非高雄组及对照组(P0.05),非高雄组高于对照组(P0.05);高雄组、非高雄组的DHEAS及AD水平均高于对照组(P0.05);3组的DHEA水平比较,差异均无统计学意义。结论:血清T、AD、DHEAS及FTI均为诊断PCOS高雄激素血症的敏感指标;T及FTI是PCOS分型(高雄及非高雄)的主要依据;LC-MS和化学发光免疫分析法对PCOS高雄激素血症的诊断具有一致性。     

Serum levels of DHEAS in gynecologic endocrinopathy and infertility

Serum dehydroepiandrosterone sulfate (DHEAS) was measured in 32 infertility patients who were found to be ovulatory, in 37 women with oligomenorrhea, and in 52 hirsute patients under basal conditions. It was also measured in conjunction with adrenocorticotropic hormone (ACTH) stimulation and dexamethasone suppression in 10 of the hirsute women. Serum DHEAS levels were elevated in only 19% of the infertile women with regular ovulation, in 34% of the oligomenorrheic patients, and in 60% of the hirsute women. Of the C-19 steroids (androgens) measured in the 52 hirsute women, ie, total and unbound serum testosterone (T), androstenedione (A), and DHEAS, unbound serum T was most frequently elevated. Eighty-two percent of the hirsute women had either an elevated serum DHEAS level or an increased unbound T level, suggesting 1) that elevations in unbound serum T may be associated with or result from increased serum DHEAS levels and 2) that only a minority of women with so-called idiopathic hirsutism do not have demonstrable androgen excess. Three of 10 hirsute women with elevated serum DHEAS levels had an increased ACTH-induced rise in DHEAS. Dexamethasone given as a single daily dose of 0.5 mg at bedtime resulted in a marked decrease in serum DHEAS in all of the 10 hirsute patients tested within 2 weeks of therapy. Thus, serum DHEAS is a clinically useful indication of adrenal C-19 steroid secretion. When combined with clinical and other hormonal evaluations, its measurement adds an important dimension to the study of gynecologic endocrinology and infertility.     

The relationship between plasma levels of leptin and androgen in healthy and preeclamptic pregnant women

BACKGROUND: To clarify the role of leptin and androgens in the pathogenesis of preeclampsia, we wanted to assess role of maternal leptin in women with severe and mild preeclampsia and the effects of sex steroid hormones on leptin production. METHODS: The groups consisted of 40 healthy pregnant women (HPW) as well as 55 pregnant women with severe preeclampsia (SPE) and 41 pregnant women with mild preeclampsia (MPE). No significant differences were observed between the three groups regarding age, gestational age and body mass index (BMI). Plasma leptin, total testosterone (T), estradiol (E(2)), dehydroepiandrosterone sulfate (DHEAS) and androstenedione (A) levels were measured. Statistical analysis was achieved with one-way analysis of variance (anova) followed by post hoc multiple comparisons with the Tukey honestly significant difference (HSD) test by using SPSS for Windows statistical computer program, and the Pearson's coefficient of correlation was calculated. RESULTS: The plasma level of leptin was significantly increased in the SPE and MPE groups (p < 0.001), whereas the plasma level of T was significantly increased only in the SPE group (p < 0.001). However, there was no significant difference in plasma levels of DHEAS among the three groups (p < 0.05). The plasma level of A was significantly decreased in the MPE group (p < 0.05). There was no significant difference in the plasma level of E(2) in the MPE and SPE groups (p < 0.05). There was a significant positive correlation between the plasma levels of leptin and E(2) in the MPE group (r = 0.41, p < 0.001). CONCLUSION: We concluded that the elevated plasma levels of leptin and testosterone could contribute to the endothelial dysfunction involved in the pathogenesis of preeclampsia, and that estradiol might lead to an increase in the plasma levels of leptin.     

Recombinant follicle-stimulating hormone stimulates ovarian androgen synthesis in down-regulated ovulatory women

In order to study androgen secretion during controlled ovarian hyperstimulation for in-vitro fertilization-embryo transfer ,an open randomized study comparing the response to recombinant or urinary follicle-stimulating hormone (FSH) in down-regulated cycles was performed. During FSH administration significant increases in testosterone ,androstenedione and dehydroepiandrosterone sulfate (DHEAS) levels were observed. During the same period a slight decrease in luteinizing hormone (LH) levels was seen. At all times during the stimulation period a significant correlation between estradiol and testosterone or androstenedione levels was observed. We conclude that FSH ,through granulosa derived paracrine factors ,initiates thecal androgen synthesis and secretion.     

The endocrine effects of spironolactone used as an antiandrogen

Eight castrate, estrogen-replaced women were given 200 mg spironolactone daily for 4 weeks. The response of plasma dehydroepiandrosterone sulfate (DHEAS), testosterone (T), and androstenedione (delta 4A), all indicators of adrenal C19-steroid production, varied greatly among individuals. Sixteen women with idiopathic hirsutism were given night-time dexamethasone (DEX) and then superimposed spironolactone for 4 weeks, followed by DEX without spironolactone for an additional 4 weeks. As expected, DHEAS, T, and delta 4A declined on DEX treatment. On addition of spironolactone, there was little further change in DHEAS, while plasma T declined in 7 of 16 women, including all those whose T level had remained elevated despite DEX treatment; most values rebounded when spironolactone was discontinued. The authors conclude from intact DEX-suppressed women that ovarian T, especially when increased, is frequently lowered by spironolactone. Thus, both adrenal and ovarian androgen production (as measured by prevailing plasma levels) may be diminished by this agent. These highly variable effects on androgen production are unlikely to account for the consistent antiandrogenic effects reported clinically.     

Outcome of corticotropin stimulation testing in women with androgen excess and ovulatory dysfunction.

OBJECTIVE: Our objective was to evaluate women with clinical signs or chemical evidence of androgen excess by corticotropin stimulation testing. STUDY DESIGN: Seventy-six women with evidence of androgen excess were evaluated by corticotropin stimulation testing. Results were examined by plasma levels of dehydroepiandrosterone sulfate, androstenedione, and testosterone. Conception in those infertile women with androgen excess was also assessed. Data were evaluated with Fisher's exact test. RESULTS: Of 41 women with dehydroepiandrosterone sulfate levels greater than 2.8 micrograms/ml, 17 (41.5%) had a positive corticotropin stimulation test (stimulated 17 alpha-hydroxyprogesterone value exceeded baseline value by 2.7 times). No statistically significant association was found between androstenedione or testosterone excess and a positive corticotropin stimulation test. In 14 infertile women with dehydroepiandrosterone sulfate levels greater than 2.8 micrograms/ml and a positive corticotropin stimulation test, 7 (50%) conceived when given low-dose prednisone (p less than 0.005). CONCLUSION: Corticotropin stimulation testing is warranted in women with clinical signs of androgen excess and dehydroepiandrosterone sulfate levels greater than 2.8 micrograms/ml.     

Androgen levels of preeclamptic patients in the third trimester of pregnancy and six weeks after delivery.

BACKGROUND: The aim of this study was to measure the circulating levels of androgens in the third trimester of pregnancy and six weeks after delivery and to discuss androgen contribution in the pathogenesis of preeclampsia. METHODS: Twenty-two preeclamptic and 20 normotensive women completed this prospective study. Blood samples were drawn in the third trimester (28-32 gestational weeks) and six weeks after delivery. Serum total testosterone (T), free testosterone (fT) dehydroepiandrosterone sulfate (DHEAS), androstenodione (A), sex hormone binding globulin (SHBG) and estradiol (E2) levels were measured. The statistical analyses of the data were performed by using Wilcoxon Rank test within the groups, Student unpaired t test and Chi-square test between the groups with the SPSS program. RESULTS: T and fT levels were found to be significantly higher (p<0.05) in preeclamptic women in the third trimester compared to the values of normotensive controls. However, there were significant decreases (p<0.05) in T and fT levels six weeks after delivery, reaching values not significantly different from normotensive subjects (p>0.05). Furthermore, SHBG, DHEAS, A and E2 levels were not significantly different (p>0.05) between the groups in the third trimester or six weeks after delivery. CONCLUSION: We conclude that higher blood androgen levels measured in preeclamptic patients may be implicated in the pathogenesis of preeclampsia.     

High levels of serum allopregnanolone in women with premature ovarian failure

The endocrine characteristics of patients with premature ovarian failure (POF) have not been fully elucidated. The aim of the present study was to evaluate whether steroidogenic activity in women with POF is different with respect to fertile and postmenopausal subjects.

In particular, circulating levels of allopregnanolone, a neuroactive steroid involved in modulation of reproductive function in rats, have been evaluated and correlated with serum levels of Δ4 precursor (dehydroepiandrosterone sulfate (DHEAS)), A5 intermediates (androstenedione, 17-hydroxyprogesterone (17-OHP), progesterone) and final products (estradiol and testosterone) of androgens. Levels of luteinizing hormone (LH), follicle stimulating hormone (FSH) and sex hormone binding globulin (SHBG) were also determined. In all cases specific radioimmunological assays were used. Women with POF showed statistically significantly lower concentrations of 17-OHP, androstenedione and testosterone when compared to fertile controls, while no differences were found between women with POF and postmenopausal women. Serum DHEAS levels were similar in POF patients and in fertile controls and higher with respect to postmenopausal women. Serum allopregnanolone levels were significantly higher in women with POF than in postmenopausal and infertile women. A significant inverse correlation between allopregnanolone levels and menopausal age in patients with POF was observed while no significant correlation was found between allopregnanolone and progesterone, androstenedione, 17-OHP and testosterone levels. In conclusion, allopregnanolone is scarcely influenced by the reduction of ovarian and adrenal activity observed in POF.     

Low maternal serum levels of placenta growth factor as an antecedent of clinical preeclampsia

OBJECTIVE: Maternal serum placenta growth factor levels have been shown to be significantly reduced in women with established preeclampsia. However, the temporal change in serum placenta growth factor levels before the clinical onset of preeclampsia is not known. STUDY DESIGN: Serum samples were collected from patients at the first prenatal (5-15 weeks' gestation), second-trimester (16-20 weeks' gestation), and third-trimester (26-30 weeks' gestation) visits. Serum placenta growth factor levels were determined and analyzed according to pregnancy outcome. RESULTS: Maternal placenta growth factor levels during normal gestation increased dramatically from the first to the third trimester. At the same gestational time points, in contrast, significantly lower serum placenta growth factor levels were found in patients in whom mild or severe preeclampsia eventually developed (P <.01). Low maternal serum placenta growth factor levels during early gestation were associated with a significant odds ratio for development of preeclampsia (P <.005). CONCLUSION: Relatively decreased levels of serum placenta growth factor occur before the onset of clinical preeclampsia, which suggests that placenta growth factor measurement could be used to discriminate those pregnancies predisposed to development of preeclampsia.     

Is There a Correlation Between Androgens and Sexual Desire in Women?

IntroductionFor women, the correlation between circulating androgens and sexual desire is inconclusive. Substitution with androgens at physiological levels improves sexual function in women who experience decreased sexual desire and androgen deficiency from surgical menopause, pituitary disease, and age-related decline in androgen production in the ovaries. Measuring bioactive testosterone is difficult and new methods have been proposed, including measuring the primary androgen metabolite androsterone glucuronide (ADT-G).AimThe aim of this study was to investigate a possible correlation between serum levels of androgens and sexual desire in women and whether the level of ADT-G is better correlated than the level of circulating androgens with sexual desire.MethodsThis was a cross-sectional study including 560 healthy women aged 19–65 years divided into three age groups. Correlations were considered to be statistically significant at P < 0.05.Main Outcome MeasureSexual desire was determined as the total score of the sexual desire domain of the Female Sexual Function Index. Total testosterone (TT), calculated free testosterone (FT), androstenedione, dehydroepiandrosterone sulfate (DHEAS), and ADT-G were analyzed using mass spectrometry.ResultsSexual desire correlated overall with FT and androstenedione in the total cohort of women. In a subgroup of women aged 25–44 years with no use of systemic hormonal contraception, sexual desire correlated with TT, FT, androstenedione, and DHEAS. In women aged 45–65 years, androstenedione correlated with sexual desire. No correlations between ADT-G and sexual desire were identified.ConclusionsIn the present study, FT and androstenedione were statistically significantly correlated with sexual desire in the total cohort of women. ADT-G did not correlate more strongly than circulating androgens with sexual desire and is therefore not superior to measuring circulating androgens by mass spectrometry.

Different maternal serum hCG levels in pregnant women with female and male fetuses: does fetal hypophyseal--adrenal--gonadal axis play a role?

Fetal gender has a significant effect on maternal and cord blood hCG levels, particularly during the last trimester of the pregnancy. However, the reason for this difference is obscure. The aim of the present study was to investigate whether term fetal hypophyseal - adrenal - gonadal axis differs between female and male fetuses thereby causing different hCG levels. The study consisted of 60 women with singleton pregnancies in the third trimester. Thirty-one pregnant women were carrying female fetuses, whereas 29 were carrying male. Human chorionic gonadotropin (hCG), estradiol, progesterone, testosterone, dehydro-epiandrosteron-sulfate (DHEAS), prolactin and growth hormone levels were measured in maternal serum and umbilical cord blood. In female bearing pregnancies maternal and cord blood hCG levels were significantly higher than in male bearing pregnancies (P<0.001). Maternal and cord blood estradiol, progesterone, testosterone, DHEAS, prolactin and growth hormone levels were not significantly different in either fetal gender. When all patients were considered as a group there were no correlations between fetal hCG levels and any of the measured hormones. Term fetal DHEAS, estrogen, progesterone, testosterone, growth hormone and prolactin levels do not contribute to different hCG levels between female and male fetuses. It is possible that fetal hypophyseal-adrenal gonadal axis does not play a central role as the cause of different hCG levels.
