PCOS患者药物促排卵中LUFS发生的相关因素

目的 探讨多囊卵巢综合征(PCOS)患者药物诱导排卵治疗中发生未破裂黄素化卵泡综合征(LUFS)的相关因素。方法 对比克罗米酚(CC)及人绝经后促性腺激素(HMG)方案用药前后PCOS患者血清PRL、FSH、LH、E_2、T水平,阴道超声检查卵巢形态,分析PCOS患者LUFS发生与基础性激素水平和卵巢形态的关系。结果 应用CC加用HCG45例,卵泡发育率66.67％,周期妊娠率为22.22％,LUFS发生率33.33％;应用CC无效者,应用HMG方案30例,卵泡发育率高(86.67％),但LUFS和过度刺激综合征(OHSS)发生率高分别为36.67％和13.33％,周期妊娠率16.67％。T水平LUFS组高于排卵组,表明LUFS的发生与血清睾酮水平有关。周边囊泡型多囊卵巢(PCP)LUFS发生率25％,普通囊泡型多囊卵巢(GCP)LUPS发生率75％。结论 普通囊泡型多囊卵巢患者易于发生卵泡黄素化不破裂综合征,可能与患者雄激素水平相对较高,卵巢包膜厚,优势卵泡不是发生在卵巢周边有关。

Effect of clomiphene citrate on endometrium thickness and echogenic patterns.

OBJECTIVE: To study the effect of clomiphene citrate (CC) on the thickness and echogenic pattern of the endometrium using vaginal sonography. METHOD: In this experimental prospective study, CC was given to 31 women with unexplained infertility. Thickness and echo patterns of the endometrium, as well as estradiol (E2) and progesterone (P) levels, were compared in women taking CC and in control patients during both the late proliferative and midsecretory phases of the menstrual cycle. RESULTS: Endometrial thickness was significantly thinner in women taking CC (P<0.03) than in controls during the late proliferative phase but there was no significant difference during the midsecretory phase. The endometrial echogenic patterns of women taking CC who had conceived revealed endometrial thicknesses of grade III and grade IV on midsecretory days, but these findings were not significantly different from those of women who had not conceived (P=0.3). Serum E2 level was higher in women taking CC than in the controls on both late proliferative and midsecretory days (P<0.05). CONCLUSION: CC affects endometrium thickness on late proliferative days but not on midsecretory days, and does not alter the echogenic pattern of the endometrium.     

Luteinizing hormone affects uterine receptivity independently of ovarian function

Previous studies have suggested that LH, in addition to its well-known effects on the ovary, may exert direct effects on the uterus. This study evaluated the effects of mid-cycle administration of human chorionic gonadotrophin (HCG), which signals through the LH receptor, on endometrial thickness and uterine receptivity in two groups of women lacking ovarian activity and receiving embryos from an oocyte donation programme. Patients in one group still had ovulatory cycles, but their ovarian function was suppressed by pituitary down-regulation with a gonadotrophin-releasing hormone (GnRH) agonist in the embryo transfer cycle, resulting in low endogenous LH concentrations. Patients in the other group were menopausal women whose pituitary function was not down-regulated in the embryo transfer cycle and whose endogenous LH concentrations were thus high. Patients in each of the two groups were randomized into two subgroups. Patients in one subgroup were given 5000 IU of HCG 2 days before oocyte recovery in the corresponding donor. Patients in the other subgroup received placebo at the same time. Oocytes from each donor were randomly distributed between one patient from the HCG subgroup and one patient from the placebo subgroup in each patient group. Endometrial growth and secretory transformation were stimulated by sequential treatment with oestradiol valerate and progesterone. In women with low endogenous LH receiving placebo, endometrial thickness stopped increasing at the beginning of secretory transformation. Mid-cycle HCG administration resulted in a continuous increase in endometrial thickness through this period, improved the implantation rate after embryo transfer in these women (30.6 versus 20.7%) and augmented the number of multiple pregnancies. No similar stagnation of endometrial thickness and no effects of mid-cycle HCG administration on endometrial thickness, the implantation rate and the number of multiple pregnancies were found in women with high endogenous LH. It is concluded that endometrial maturation is disturbed in women with low endogenous LH but can be rescued by mid-cycle stimulation of LH receptor with exogenous HCG in the absence of ovarian activity.     

Modulation of luteinizing hormone secretion by estrogens in patients with Reifenstein's syndrome

The role of estrogens on gonadotropin secretion was assessed in two siblings with incomplete virilization syndrome type I due to partial androgen insensitivity (Reinfenstein's syndrome). Serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured before and after 100 micrograms LH-releasing hormone (RH) intravenous (IV) stimulation, as well as during long-term clomiphene citrate (CC) administration. Serum testosterone (T) and estrogens were determined before and during daily administration of human chronic gonadotropin (hCG) and also during the CC treatment. Basal levels of LH were elevated in both patients: 12.5 +/- 1.1 mIU in patient A and 19.8 +/- 1.8 mIU/ml in patient B. Conversely, FSH levels were within normal limits. Administration of LH-RH in both subjects induced a rise in LH levels, while FSH concentration showed no increase. The CC administration resulted in a significant (P less than 0.005) increment in serum LH levels without changes in FSH concentration. An important increase of serum T and estradiol (E2) levels was noted during CC administration; thus, in patient A those levels augmented from 20 to 48 ng/ml for T and from 78 to 220 pg/ml for E2; and patient B showed an increment from 20 to 35 ng/ml for T, and from 55 to 180 pg/ml for E2. The daily administration of hCG was followed by an increment in both T and E2 levels, which was of lesser degree for estrone concentration. These results suggest that endogenous estrogens, particularly E2, modulate LH secretion in patients with partial androgen insensitivity; however, it appears that estrogens had no physiologic effect on FSH secretion.     

Endometrial development was improved by transdermal estradiol in patients treated with clomiphene citrate.

The objective of this study was to examine the effect of transdermal estrogen therapy on the endometrial thickness and serum hormone levels in anovulatory patients treated with clomiphene citrate (CC). There was a significant difference in endometrial thickness between the CC + transdermal estrogen group and the CC only group from day -2 to day +2. Serum estradiol (E2) levels in the CC + transdermal estrogen group were significantly higher than those in the CC only group on day -2 and day 0. Our results support that addition of transdermal E2 to the treatment protocol of the women treated with CC elicited a favorable response of the endometrium.

来曲唑联合克罗米芬治疗多囊卵巢综合征患者的疗效及对排卵、妊娠情况的影响#br#

Objective?To investigate the clinical effect of letrozole (LE) combined with clomiphene (CC) in the treatment of polycystic ovary syndrome (PCOS). Methods?A total of 120 patients with PCOS were selected as the research objects, of which 60 patients who received single CC treatment were the control group, while the combined group (60 patients) was given LE+CC treatment. Menstrual conditions and sex hormone levels [luteinizing hormone (LH), estradiol (E2), and progesterone (P)] were compared between the two groups, and ovulation and pregnancy were recorded in the two groups. Results?The number of mature follicles, endometrial thickness, menstrual cycle, menstrual volume and early abortion rate in the combined group were lower than those in the control group (P<0.05). After treatment, E2, LH, P secretion levels, ovulation rate, pregnancy rate and twin rate in the combined group were higher than those in the control group (P<0.05). Conclusion? LE combined with CC in the treatment of PCOS patients can achieve better efficacy in ovulation induction and pregnancy.
