Abstract

Mutations of the fragile X mental retardation 1 (FMR1) gene are associated with distinct ovarian aging patterns.To confirm in human in vitro fertilization (IVF) that FMR1 affects outcomes, and to determine whether this reflects differences in ovarian aging between FMR1 mutations, egg/embryo quality or an effect on implantation.IVF outcomes were investigated in a private infertility center in reference to patients' FMR1 mutations based on a normal range of CGG(n = 26-34) and sub-genotypes high (CGG(n>34)) and low (CGG(

Abstract

Hypoandrogenism in women with low functional ovarian reserve (LFOR, defined as an abnormally low number of small growing follicles) adversely affects fertility. The androgen precursor dehydroepiandrosterone (DHEA) is increasingly used to supplement treatment protocols in women with LFOR undergoing in vitro fertilization. Due to differences in androgen metabolism, however, responses to DHEA supplementation vary between patients. In addition to overall declines in steroidogenic capacity with advancing age, genetic factors, which result in altered expression or enzymatic function of key steroidogenic proteins or their upstream regulators, might further exacerbate variations in the conversion of DHEA to testosterone. In this Review, we discuss in vitro studies and animal models of polymorphisms and gene mutations that affect the conversion of DHEA to testosterone and attempt to elucidate how these variations affect female hormone profiles. We also discuss treatment options that modulate levels of testosterone by targeting the expression of steroidogenic genes. Common variants in genes encoding DHEA sulphotransferase, aromatase, steroid 5α-reductase, androgen receptor, sex-hormone binding globulin, fragile X mental retardation protein and breast cancer type 1 susceptibility protein have been implicated in androgen metabolism and, therefore, can affect levels of androgens in women. Short of screening for all potential genetic variants, hormonal assessments of patients with low testosterone levels after DHEA supplementation facilitate identification of underlying genetic defects. The genetic predisposition of patients can then be used to design individualized fertility treatments.

Abstract

STUDY QUESTION Is diminished functional ovarian reserve (DFOR) associated with low androgen levels? SUMMARY ANSWER Low androgen levels are associated with DFOR at all ages. WHAT IS KNOWN ALREADY Androgen supplementation via dehydroepiandrosterone (DHEA) has been reported to improve functional ovarian reserve (FOR); pregnancy rates in IVF cycles are associated with how well DHEA converts to testosterone (T); and androgen effects through the androgen receptor have been demonstrated in mice to beneficially affect early stages of follicle maturation. STUDY DESIGN, SIZE, DURATION In a controlled cohort study we investigated consecutive women presenting to our center with two forms of DFOR, premature ovarian aging/occult primary ovarian insufficiency (POA/OPOI) and physiologic diminished ovarian reserve (DOR). As controls for POA/OPOI patients, infertile women with normal age-specific FOR were recruited. PARTICIPANTS/MATERIALS, SETTINGS, METHODS The study involved 140 women with POA/OPOI, defined as age 40 years. Forty-nine control patients

Abstract

The integrity of mitosis is dependent upon strict regulation of microtubule stability and dynamics. Although much information has been accumulated on regulators of the microtubule cytoskeleton, our knowledge of the specific pathways involved is still limited. Here we designed genetic screens to identify regulators of microtubule stability that are dispensable in the wild type yet become essential under microtubule-disrupting conditions. We found that the transcriptional cofactor Swi6p and activator Swi4p, as well as the G 2 /M-specific cyclin Clb2p, are required in a microtubule-destabilizing environment. Swi6p and Swi4p can combine as a transcriptional complex, called the SBF complex (SBF for Swi4/6 cell cycle box [SCB]-binding factor) that is functionally homologous to the metazoan DP1/2-E2F complex and that controls the G 1 /S transition through the genes it regulates. We show that Swi6p's contribution to microtubule stability can be either dependent or independent of the SBF complex. The SBF-dependent pathway requires downregulation of SBF complex levels and may thereby reroute the transcriptional program in favor of greater microtubule stability. This pathway can be triggered by overexpression of Fcp1p, a phosphatase in the general transcription machinery, or by expression of an allele of SWI6 that is associated with reduced transcription from SBF-controlled promoters. The SBF-independent pathway is activated by a constitutively nuclear allele of Swi6p. Our results introduce novel roles in microtubule stability for genes whose participation in the process may be masked under normal conditions yet nonetheless acquire a dominant role when microtubule stability is compromised.

Abstract

Objective To investigate whether granulocyte colony-stimulating factor (G-CSG) affects endometrial thickness, implantation rates, and clinical pregnancy rates in routine, unselected IVF cycles. Design Registered, individually randomized, two-group, parallel double-blinded placebo-controlled clinical trial. Setting Academically affiliated private clinical and research center. Patient(s) 141 consecutive, unselected, consenting women with no history of renal disease, sickle cell disease, or malignancy who were undergoing IVF. Intervention(s) Sealed, numbered, opaque envelopes assigned 73 patients to receive G-CSF (Filgrastim, Amgen, 300 μg/1.0 mL) and 68 to receive placebo (saline). Main Outcome Measure(s) Endometrial thickness, clinical pregnancy, and embryo implantation rates. Result(s) The mean age for the whole study group was 39.59 ± 5.56 years (G-CSF: 39.79 ± 5.13 years; placebo: 39.38 ± 6.03 years). Endometrial thickness statistically significantly increased over the 5-day observation period for the whole group by approximately 1.36 mm. The increase in the G-CSF group was not statistically significantly different from the control group. Statistical models looking at treatment effects on clinical pregnancy and implantation rates demonstrated no effect of G-CSF treatment. There were no adverse events for either treatment group. Conclusion(s) In normal IVF patients, G-CSF does not affect endometrial thickness, implantation rates, or clinical pregnancy rates. Because these results were obtained in an older patient population, they may not necessarily apply to younger women. Clinical Trial Registration Number NCT01202656.

Abstract

Context: FSH and anti-Müllerian hormone (AMH) are, individually, widely used to assess functional ovarian reserve (FOR) but demonstrate discrepancies in efficacy. How predictive they are combined is unknown. Objective: The purpose of this study was to assess predictive values of different FSH and AMH combinations on in vitro fertilization (IVF). Design and Setting: FSH and AMH levels in patients were categorized as low, normal, and high, based on age-specific 95% confidence intervals. This allowed for establishment of nine combinations of low, normal, or high FSH/AMH patient categories. With use of various statistical methods, patients in individual categories were then compared in outcomes. Patients: We investigated 544 consecutive infertility patients in their first IVF cycles. Interventions: IVF cycles were managed. Main Outcome Measures: Oocyte yields and implantation and pregnancy rates, adjusted for age and fragile X mental retardation 1 (FMR1) genotypes/subgenotypes, were measured. Results: The most notable repeated finding was a strong statistical association of the FSH/AMH high/high category (characterized by abnormally high FSH and AMH levels) with favorable IVF outcomes compared with outcomes for other FSH/AMH variations (4.34 times odds of high oocyte yields and 1.93 times odds of clinical pregnancy). Addition of age to the model only minimally further improved the odds of pregnancy to 2.03 times. The positive association with high oocyte yields, however, turned negative (0.75 times lower yields) with addition of FMR1 to the model for women with FSH/AMH high/high and the het-norm/low FMR1 subgenotype compared with women with the norm FMR1 genotype and other FSH/AMH categories. Conclusions: In the absence of het-norm/low FMR1, abnormally high FSH and AMH, a seemingly contradictory combination, reflects highly beneficial outcomes in IVF compared with the other FSH/AMH categories, suggesting greater importance of FSH in early follicle maturation than currently recognized. The study also confirms adverse outcome effects of het-norm/low FMR1 and, therefore, the gene's importance for reproductive success.

Abstract

Objective To evaluate the relationship between transforming growth factor (TGF)-β1 and its receptor, soluble endoglin (sENG), in the serum and follicular fluid of women with polycystic ovarian syndrome (PCOS) compared with that of non-PCOS normal ovulating women during controlled ovarian stimulation (COS). Design Prospective case-control study. Setting Academic-affiliated assisted reproductive technology unit. Patient(s) Fourteen PCOS and 14 matched non-PCOS control women undergoing COS. Intervention(s) Serum was collected on day 3 (baseline), day of hCG, and day of retrieval. Follicular fluid (FF) was collected on day of oocyte retrieval. ELISA was performed to determine TGF-β1 and sENG protein levels. Main Outcome Measure(s) Serum and FF levels of TGF-β1 and sENG. Result(s) Serum TGF-β1 did not change significantly during COS but was increased in PCOS compared with non-PCOS women on day 3 and days of hCG administration and oocyte retrieval. Serum sENG increased after hCG administration only in the non-PCOS control group. In addition, serum sENG was decreased in PCOS compared with non-PCOS control women on the days of hCG and retrieval. Accordingly, the bioavailability of TGF-β1 (TGF-β1/sENG ratio) was increased in women with PCOS compared with non-PCOS controls at all three time points. No differences in either factor were noted in FF between groups. Conclusion(s) The increased TGF-β1 bioavailability in PCOS is not only due to increased TGF-β1 levels but also to decreased levels of its receptor, sENG. These data suggest that increased TGF-β1 bioavailability may contribute to the pathogenesis of PCOS and its increased risk for ovarian hyperstimulation.

Abstract

To investigate whether androgen conversion rates after supplementation with dehydroepiandrosterone (DHEA) differ, and whether differences between patients with diminished ovarian reserve (DOR) are predictive of pregnancy chances in association with in vitro fertilization (IVF). In a prospective cohort study we investigated 213 women with DOR, stratified for age (≤38 or >38 years) and ovarian FMR1 genotypes/sub-genotypes. All women were for at least 6 weeks supplemented with 75 mg of DHEA daily prior to IVF, between initial presentation and start of 1st IVF cycles. Levels of DHEA, DHEA-sulfate (DHEAS), total T (TT) and free T (FT) at baseline (BL) and IVF cycle start (CS) were then compared between conception and non-conception cycles. Mean age for the study population was 41.5 ± 4.4 years. Forty-seven IVF cycles (22.1 %) resulted in clinical pregnancy. Benefits of DHEA on pregnancy rates were statistically associated with efficiency of androgen conversion from DHEA to T and amplitude of T gain. Younger women converted significantly more efficiently than older females, and selected FMR1 genotypes/sub-genotypes converted better than others. FSH/androgen and AMH/androgen ratios represent promising new predictors of IVF pregnancy chances in women with DOR. DOR at all ages appears to represent an androgen-deficient state, benefitting from androgen supplementation. Efficacy of androgen supplementation with DHEA, however, varies depending on female age and FMR1 genotype/sub-genotype. Further clarification of FMR1 effects should lead to better individualization of androgen supplementation, whether via DHEA or other androgenic compounds.

Abstract

Is thin endometrium unresponsive to standard treatments expandable by intrauterine perfusion with granulocyte colony-stimulating factor (G-CSF)?This cohort study is supportive of the effectiveness of G-CSF in expanding chronically unresponsive endometria.In a previous small case series, we reported the successful off-label use of G-CSF in four consecutive patients, who had previously failed to expand their endometria beyond 6.9 mm with the use of standard treatments.In a prospective observational cohort pilot study over 18 months, we described 21 consecutive infertile women with endometria7 mm on the day of hCG administration in their first IVF cycles at our center. All previous cycles using traditional treatments with estradiol, sildenafil citrate (Viagra™) and/or beta-blockers had been unsuccessful. G-CSF (Nupogen™) was administered per intrauterine catheter by slow infusion before noon on the day of hCG administration. If the endometrium had not reached at least a 7-mm within 48h, a second infusion was given following oocyte retrieval. Primary and secondary main outcomes were an increase in endometrial thickness and clinical pregnancy, respectively. Endometrial thickness was assessed by vaginal ultrasound at the most expanded area of the endometrial stripe.This study was uncontrolled, each patient serving as her own control in a prospective evaluation of endometrial thickness. The mean ± SD age of the cohort was 40.5 ± 6.6 years, gravidity was 1.8 ± 2.1 (range 0-7) and parity was 0.4 ± 1.1 (range 0-4); 76.2% of women had, based on age-specific FSH and anti-Müllerian hormone, an objective diagnosis of diminished ovarian reserve and had failed 2.0 ± 2.1 prior IVF cycles elsewhere.With 5.2 ± 1.9 days between G-CSF perfusions and embryo transfers, endometrial thickness increased from 6.4 ± 1.4 to 9.3 ± 2.1 mm (P0.001). The Δ in change was 2.9 ± 2.0 mm, and did not vary between conception and non-conception cycles. A 19.1% ongoing clinical pregnancy rate was observed, excluding one ectopic pregnancy.Small sample size (but a highly selected patient population) in an uncontrolled cohort study and in unselected first IVF cycles at our center.This pilot study supports the utility of G-CSF in the treatment of chronically thin endometrium and suggests that such treatment will, in very adversely affected patients, result in low but very reasonable clinical pregnancy rates.This work was supported by the Foundation for Reproductive Medicine, New York, New York, USA, a not-for-profit research foundation and intramural grants from the Center for Human Reproduction (CHR)-New York.
