Does theFMR1 gene affect IVF success?

FMR1 CGG trinucleotide repeat expansions are associated with Fragile X syndrome (full mutations) and primary ovarian insufficiency (premutation range); the effect of FMR1 on the success of fertility treatment is unclear. The effect of FMR1 CGG repeat lengths on IVF outcomes after ovarian stimulation was reviewed. PubMed was searched for studies on IVF-related outcomes reported by FMR1 trinucleotide repeat length published between 2002 and December 2017. For women with CGG repeats in the normal (<45 CGG), intermediate range (45–54 CGG), or both, research supports a minimal effect on IVF outcomes, including pregnancy rates; although one study reported lower oocyte yields after IVF stimulation in women with lower CGG repeat lengths and normal ovarian reserve. Meta-analysis revealed no association within subcategories of normal repeat length (<45 CGG) and IVF pregnancy rates (summary OR 1.0, 95% CI 0.87 to 1.15). Premutation carriers (CGG 55–200) may have reduced success with IVF treatment (lower oocyte yield) than women with a normal CGG repeat length or a full mutation, although findings are inconsistent. Direct implications of the repeat length on inheritance and the risk of Fragile X syndrome have been observed. Patients may require clinical and psychological counselling, and further preimplantation genetic testing options should be considered. Thus, there are clinical and psychological counseling implications for patients and potential further patient decisions regarding preimplantation genetic testing options.     

Does local injury to the endometrium before IVF cycle really affect treatment outcome? Results of a randomized placebo controlled trial

Aim: To evaluate the effect of local injury to the endometrium during spontaneous menstrual cycles before in vitro fertilization (IVF) treatment on implantation and pregnancy rates in women with recurrent implantation failure (RIF). Methods: In a prospective randomized controlled trial (RCT), a total of 36 patients, with RIF undergoing IVF, were randomized to two groups. In 18 patients, endometrial biopsies were performed using a pipelle curette on days 9–12 and 21–24 of the menstrual cycle preceding IVF treatment. In 18 control patients, a cervical pipelle was performed. Results: The implantation rate (2.08% versus 11.11%; p?=?0.1), clinical (0% versus 31.25%; p?<?0.05) and live births rates (0% versus 25%; p?=?0.1) were lower in the experimental group compared with controls. Conclusion: Our RCT did not find any benefit from local injury to the endometrium in women with a high number of RIFs. Further studies are warranted to better define the target population of patients who may benefit from this procedure.     

Do uterine fibroids affect IVF outcomes?

The effect of myomectomy on implantation and pregnancy rates prior to assisted reproduction treatments is controversial. This study was designed to assess clinical outcomes of IVF cycles in women with uterine fibroids. A retrospective single-centre assessment of clinical outcomes of IVF/intracytoplasmic sperm injection (ICSI) treatments in infertile women in a 4-year span was carried out. All patients underwent detailed transvaginal ultrasound and hysteroscopy to precisely identify presence, location and intracavitary growth of uterine fibroids. Cumulative pregnancy, ongoing pregnancy and live birth rates were considered primary outcome measurements. Fifty-one women with fibroids (97 treatment cycles), 63 patients with previous myomectomy (127 cycles), and 106 infertile women who did not demonstrate fibroids anywhere in the uterus (215 cycles) were considered for the analysis. No significant difference was found for pregnancy and live birth rates between groups. Women with fibroids>4 cm required an increased number of cycles to obtain an ongoing pregnancy, compared with the other groups. The data do not support pre-IVF myomectomy in women with small-to-moderate uterine fibroids, regardless of their location. This represents valuable information in the counselling of women with fibroids before reproductive assisted cycles.     

Does stress affect IVF outcomes? A prospective study of physiological and psychological stress in women undergoing IVF

Research questionWhat are the effects of physiological and psychological stress on fertility outcomes for women undergoing IVF?DesignA prospective cohort study of 72 patients undergoing IVF in 2017 and 2018. Physiological stress was assessed by salivary cortisol measurements: (i) pretreatment, when the patient received the IVF protocol; (ii) before oocyte retrieval (follicular cortisol was also measured); and (iii) before embryo transfer. Emotional stress was evaluated at each assessment with the State-Trait Anxiety Inventory and a 1–10 Visual Analogue Scale (VAS, referred to as the ‘Stress Scale’. Correlations between cortisol concentrations, psychological stress and IVF outcome were assessed.ResultsSalivary cortisol concentrations increased by 28% from pretreatment phase (0.46 ± 0.28 μg/dl) to maximum concentration on oocyte retrieval day (0.59 ± 0.29 μg/dl, P = 0.029) and then decreased by 29% on embryo transfer day (0.42 ± 0.23 μg/dl, P = 0.0162). On embryo transfer day, cortisol among women in their first cycle was higher than women who underwent more than one treatment (P = 0.024). Stress Scale score increased by 39% from pretreatment to a maximum score on oocyte retrieval day and then decreased by 12% on embryo transfer day. Salivary cortisol and Stress Scale were not related to subsequent embryo transfer, fertilization rate, embryo quality or clinical pregnancy rate. Follicular cortisol concentration was positively correlated with fertilization rate (r = 0.4, P = 0.004).ConclusionIt can be cautiously concluded that physiological and psychological stress do not negatively affect IVF outcomes. Moreover, high follicular cortisol concentrations might have positive effects on pregnancy rates.     

Natural cycle IVF: a question of semantics?

Recently there has been much discussion and presentation on IVF protocols using less stimulation or indeed none at all. Our experience with controlled natural cycle IVF over the last few years has convinced us that this is a powerful tool for many patients in the treatment of infertility. The protocol we employ has raised some questions as to whether it is natural cycle or stimulated cycle. We have reported a large series of cycles and seen no stimulatory effects of the medications used to control the cycle, thereby confirming our position that controlled natural cycle IVF is a valid option as an assisted reproduction treatment.     

Is hysteroscopic correction of an incomplete uterine septum justified prior to IVF?

This retrospective study examined the effect of hysteroscopic correction of an incomplete uterine septum on IVF outcome. Measurement of the Fm (fundal myometrial thickness) and Cm (cornual myometrial thickness) was performed by sonohysterography. Group 1 included patients diagnosed with incomplete septum (n = 119), fulfilling the two criteria of Fm >11 mm and Fm-Cm >5 mm, who underwent hysteroscopic incision of the incomplete septum. Group 2 consisted of 116 age-matched control patients with a normal uterine cavity who underwent IVF within the same time period. Main outcome measures were clinical pregnancy and spontaneous abortion rates. Patients in group 1 had a history of more spontaneous abortions than patients in group 2 (14.20 versus 6.03%, P = 0.04) as well as higher previous IVF failure (32.7 versus 20.6%, P = 0.04). After surgical correction of the septum in group 1, IVF pregnancy outcome was similar in both groups (clinical pregnancy and pregnancy loss of 47.80 versus 46.50% and 10.52 versus 20.3% respectively). A similar pregnancy outcome was found after the incision of the incomplete septum compared with a group with normal uterine cavity. Larger prospective and randomized controlled studies are needed to prove the positive effect of correction of an incomplete uterine septum on IVF outcome.     

Does hysterectomy affect genital sensation?

OBJECTIVES: To evaluate vaginal and clitoral sensation before and after hysterectomy and to assess pre- and post-surgery changes in sexual function. STUDY DESIGN: Quantitative sensory thresholds for warm, cold, and vibratory sensations were measured at the vagina and clitoris 1 day prior to and 3 months following surgery. A survey was performed 18 months following operation to evaluate long-term changes in sexual function. PARTICIPANTS: Twenty-seven women, aged 30-57 years, who were admitted for elective hysterectomy. MAIN OUTCOME MEASURES: Genital sensation and reported sexual function. RESULTS: There was significant deterioration in sensation to cold and warm stimuli at the anterior and posterior vaginal wall after surgery. Vaginal vibratory sensation thresholds tended to increase. Clitoral thermal and vibratory sensation thresholds remained unchanged before and after surgery. Of the 22 patients who participated in the follow-up survey, 17 did not report any decline in sexual function, while 4 patients reported deterioration in genital sensation and in sexual function. CONCLUSION: The results demonstrate quantifiable sensory loss in the vagina after hysterectomy, with preservation of clitoral sensation. Only a minority of patients reported a decline in their sexual function. These findings highlight the relative importance of clitoral as compared to vaginal sensation in sexual function.     

Does day care affect development?

Abstract

Much research has been directed towards the question, does day care affect development. This question oversimplifies the issue. The definition of terms is critical in how this question is interpreted. The implicit assumptions and problems of this question are considered using data from a recent study to illustrate points to be made.     

Does maternal diet affect infantile colic?

Objective: The aim of this study was to investigate the effect of maternal diet on infantile colic without any interventions or food restrictions.

Methods: Thirty colicky and 29 non-colicky infants were included in this prospective study. Mother’s diet and baby crying time were recorded for 1 week by mothers; nutritionist classified contents of mother’s diet and compared the diet of mother in colicky and non-colicky infants.

Results: It was found that mothers of non-colicky infants consumed significantly more grapes and lemons than mothers of colicky infants (p?=?0.044). The crying time was moderately negatively correlated with the percentage of protein in the maternal diet (R?=?–0.45, p?=?0.01) and the presence of potatoes in the maternal diet (R?=?–0.38, p?=?0.034) and positively correlated with the maternal consumption of walnut (R?=?0.38, p?=?0.034), banana (R?=?0.44, p?=?0.01).

Conclusions: Removing bananas from the maternal diet may reduce colic. The consumption of a protein-rich maternal diet, grapes, lemons and potatoes by breastfeeding mothers may protect infants from colic.     

Does pregnancy affect pelvic organ mobility?

BACKGROUND: It is generally accepted that parity is a strong predictor of pelvic organ prolapse and incontinence. However, controversy persists as to whether this effect is due to pregnancy itself or parturition. AIMS: To define the contribution of early and late pregnancy to bladder mobility. METHODS: Case control series, using 88 non-pregnant control subjects recruited for a heritability study on urinary incontinence and prolapse, matched for age and ethnicity with 28 pregnant women seen at 10-17 weeks and again at 32-39 weeks' gestation. Main outcome parameters were ultrasound measures of anterior, central and posterior compartment descent as well as joint mobility measurements. RESULTS: Patients in early pregnancy showed higher values for bladder mobility in comparison with non-pregnant controls, although this did not reach significance for all parameters. However, when late pregnancy data were tested against non-pregnant controls, this difference reached significance for all tested parameters. Uterine and rectal descent did not show any significant differences between groups. Results for joint mobility were inconsistent. CONCLUSIONS: This study supports the hypothesis that bladder and urethral mobility increase in pregnancy. This effect is already noticeable at 6-18 weeks. As similar changes are also seen in elbow hyperextension, a generalised effect on connective tissue biomechanics, likely hormonal, can be hypothesised.     

Does female age affect embryo morphology?

Deteriorating oocyte quality is commonly believed to be the primary determinant of the decreased implantation potential in older women. We assessed the influence of age on embryo morphology in standard in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) modalities. All 6350 consecutive embryos (2990 IVF, 3360 ICSI) obtained in our Assisted Reproductive Technology Unit from January 1996 through June 1997 were included. High quality embryos were defined as those with equal-sized blastomeres and < 10% fragmentations and a cleavage rate of four cells on day 2 or eight cells on day 3 transfers. The results were analyzed for the standard IVF group, the ICSI group, and the ICSI subgroup with severe male factor infertility (< or = 1 x 10(6) total motile spermatozoa in the ejaculate). For standard IVF, a positive association was observed between female age and increased proportion of good quality embryos. No such association was detected for the ICSI cycles (whole group or subgroup). We conclude that in standard IVF, embryo quality, as reflected by embryo morphology, does not deteriorate with increased maternal age.     

Does erythropoietin affect motility of spermatozoa?

Introduction  

Erythropoietin, which is a hematopoietic growth factor, has been found to play a role in various physiologic processes within the body including testicular steroidogenesis and spermatogenesis. However, it is not known whether erythropoietin is also essential for the normal physiology of mature sperm cells. In this study, the effects of recombinant human erythropoietin beta (rEPO) on sperm motility were investigated.     

Does air travel affect pregnancy outcome?

Introduction Primary ovarian carcinoid tumours are uncommon neoplasias. There are distinct histological types with different behaviours: insular, trabecular, mucinous and mixed. The trabecular subtype is very rare and unlike other carcinoid subtypes, it is characterised by the absence of a clinical carcinoid syndrome and has been related with a better prognosis than the others. No distant metastases have yet been reported. Case report We present a case of a 76-year-old woman diagnosed with a left ovarian tumour. She underwent a radical hysterectomy with bilateral salpingo-oophorectomy and regional lymph node clearance. Histology revealed an ovarian trabecular carcinoid tumour and no adjuvant treatments were performed. The patient is alive and free of disease 70 months following diagnosis. Discussion Immunohistochemical staining for p53 protein, and a comparative study with other subtypes of ovarian carcinoid tumours (insular and mucinous) is discussed in this report.     

The problem of IVF cost in developing countries: has natural cycle IVF a place?

Infertility represents a national health problem in some African countries. Limited financial health resources in developing countries are a major obstacle facing infertility management. IVF is the definitive line of treatment for many couples. Stimulation cycles are associated with risks of ovarian hyperstimulation syndrome and multiple pregnancy. This study evaluates the client acceptability of stimulated versus natural cycle IVF among couples attending one infertility clinic, with respect to cost and pregnancy outcome. Of the patients who were indicated for IVF, 15% (16/107) cancelled, due mostly (12/16, 75%) to financial reasons. The majority of patients who completed their IVF treatment (82/91, 90.1%) felt the price of the medical service offered was high, and 68.1% (62/91) accepted the idea of having cheaper drugs with fewer side effects but with possibly lower chances of pregnancy. Natural cycle IVF has emerged as a potential option that might be suitable for patients worldwide, especially in developing countries.     

Does sperm origin affect embryo morphokinetic parameters?

Purpose

The purpose of our study was to use time-lapse in order to evaluate the impact of sperm origin (fresh ejaculate or surgically retrieved) on embryo morphokinetic parameters and clinical outcome in intracytoplasmic sperm injection (ICSI) cycles.

Methods

This retrospective monocentric study was conducted in 485 unselected couples undergoing 604 ICSI cycles with embryo culture in the Embryoscope®. Among them, 445 couples underwent ICSI cycle with fresh ejaculated sperm and 40 with surgically retrieved sperm (26 with testicular sperm and 14 with epididymal sperm). Embryo morphokinetic parameters and clinical cycle outcome were compared between fresh ejaculated sperm and surgically retrieved sperm. A subgroup analysis was also conducted between testicular and epididymal sperm ICSI cycles.

Results

Clinical outcome was comparable between groups according to sperm origin. Although most early morphokinetic parameters were comparable between ejaculated and surgical sperm groups, a few parameters were significantly different between both groups, but with a considerable overlap in their distribution. Late cellular events occurred significantly later in the surgical sperm group than in the ejaculated sperm group.

Conclusions

Morphokinetic analysis did not allow us to identify clinically relevant differences between fresh ejaculate and surgically retrieved sperm groups. Further studies are needed, especially concerning the relationship between sperm origin and late morphokinetic parameters, such as blastocyst development.     

Does urinary incontinence subtype affect sexual function?

Objective

Urinary incontinence (UI) may affect a woman's physical and psychological well-being in different aspects. The aim of this study was to compare the effects of urinary stress incontinence (USI), detrusor overactivity (DO) and mixed urinary incontinence (MUI) on sexual function.

Study design

One-hundred and seventy urinary incontinent, sexually active women were included in this cross-sectional study. After urodynamic evaluation, participants were divided into three subgroups as USI (n = 61), DO (n = 55) and MUI (n = 54). Patients were matched according to age, parity and body mass index (BMI), rendering the sample size to 41 patients in each group. Turkish version short form of the Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire (PISQ-12) was filled out by each of the participants. Totally, 52 patients were excluded from the study (47 could not be matched and 5 incomplete questionnaire). Demographic characteristics of the participants, total and three domain scores of PISQ-12 were compared among three UI subgroups.

Results

The study group was consisted of 38 (32.2%) DO, 41 (34.7%) USI and 39 (33.1%) MUI patients. Demographic characteristics of the patients were similar in three subgroups. Patients with a diagnosis of MUI had significantly lower mean PISQ-12 scores than the ones with USI and DO whereas patients with USI had lower mean PISQ-12 scores than patients with DO.

Conclusion

Although urinary stress incontinence effects sexual function more than detrusor overactivity in terms of PISQ-12 scores, mixed urinary incontinence has the greatest impact on sexual function when compared with urinary stress incontinence and detrusor overactivity.     

Does consanguinity affect the severity of pre-eclampsia?

To determine whether consanguinity is more likely to be associated with severe forms of pre-eclampsia/eclampsia. Presuming a pure genetic contribution, we speculated that consanguineous marriages would increase the occurrence of severe forms of pre-eclampsia/eclampsia, through an expected increased chance for homozygosity to the putative gene. The study is a clinical case series on pre-eclamptic/eclamptic primiparae delivered at Princess Badea Teaching Hospital, which is a tertiary referral center. The internationally accepted definitions for hypertension, proteinuria, mild and severe pre-eclampsia were adopted. The study included 77 primiparae. The incidence of consanguinity in the studied sample was 38%. Of them, 28 (36.4%) had mild pre-eclampsia, 45 (58.4%) had severe pre-eclampsia and four (5.2%) had eclampsia. There was no statistically significant difference in the occurrence of severe pre-eclampsia/eclampsia between primiparae married to a first cousin or a relative other than a first cousin and primiparae married to a non-relative, odds ratio 1.1 (95% CI 0.33-3.87), P value 0.94, odds ratio 2.6 (95% CI 0.45-27.6), P value 0.30, respectively. Also, there was no statistically significant difference in occurrence of severe pre-eclampsia/eclampsia between primiparae whose parents are first cousins or relatives other than a first cousin and primiparae whose parents are non-relatives, odds ratio 1.3 (95% CI 0.36-4.72), P value 0.81, odds ratio 1.61 (95% CI 0.23-18.4), P value 0.70, respectively. Our study did not support a causal relationship between consanguinity and the occurrence of severe pre-eclampsia/eclampsia. The role of more complex genetic, immunologic, metabolic, hemostatic or, possibly yet, other unknown factors have to be explored.     

Does obesity affect the vaginal hysterectomy outcomes?
