Low estradiol responses in oocyte donors undergoing gonadotropin stimulation do not influence clinical outcomes. J Assist Reprod Genet 2018; 35:1675-1682. [PMID: 29704227 DOI: 10.1007/s10815-018-1192-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2018] [Accepted: 04/18/2018] [Indexed: 10/17/2022] Open
Abstract
PURPOSE To examine the effect of low and very low estradiol responses in oocyte donors receiving gonadotropins on clinical outcomes of donor in vitro fertilization (IVF) cycles and to identify possible mechanisms responsible for low estradiol response. METHODS This is a retrospective cohort study of oocyte donors undergoing antagonist IVF cycles with progression to oocyte retrieval between January 2010 and December 2016 at a single urban academic fertility center. Oocyte yield, fertilization rate, blastocyst rate, percentage of normal embryos on preimplantation genetic screening (PGS), pregnancy outcomes, and follicular fluid steroid profiles were compared between donors with normal estradiol response and those with low estradiol response. RESULTS Three hundred sixty-six antagonist oocyte donor IVF cycles were identified: 42 cycles had a normal estradiol response (NE2), defined as peak serum estradiol (E2) of over 200 pg/mL per retrieved oocyte; 140 cycles had an intermediate estradiol response (iE2), defined as peak serum E2 between 100 and 200 pg/mL per retrieved oocyte; 110 cycles had a low estradiol response (LE2), defined as peak serum E2 between 50 and 100 pg/mL per retrieved oocyte; and 74 cycles had a very low estradiol response (vLE2), defined as peak serum E2 less than 50 pg/mL per retrieved oocyte. LE2 cycles resulted in a greater number of mature oocytes (22.4 vs. 13.6, p < 0.017), and fertilizations versus NE2 donors (18.5 vs. 10.7, p < 0.017), although the number of transferred or cryopreserved blastocysts were similar between groups (8.6, 6.9 vs. 4.8, p = 0.095, p = 1). The percentage of chromosomally normal embryos after PGS was similar between LE2, vLE2, and NE2 cycles (66.4, 71.8 vs. 63.1%, p = 0.99, p = 1). Pregnancy outcomes were similar between LE2, vLE2, and NE2 cycles. Serum AMH obtained on the day of peak E2 was similar to baseline serum AMH and did not differ between LE2 versus NE2 cycles. Follicular fluid E2 levels paralleled serum E2 levels and were lower in LE2 cycles versus NE2 cycles. CONCLUSION The prevalence of very low E2 responses in donors appears to be high (20.2%). In contrast to autologous IVF cycles, LE2 does not portend poor outcomes in oocyte donors.

Intrafollicular cortisol levels inversely correlate with cumulus cell lipid content as a possible energy source during oocyte meiotic resumption in women undergoing ovarian stimulation for in vitro fertilization. Fertil Steril 2014; 103:249-57. [PMID: 25439840 DOI: 10.1016/j.fertnstert.2014.09.034] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2014] [Revised: 09/23/2014] [Accepted: 09/23/2014] [Indexed: 01/31/2023]
Abstract
OBJECTIVE To determine whether follicular fluid (FF) cortisol levels affect cumulus cell (CC) lipid content during oocyte meiotic resumption, and whether CCs express genes for glucocorticoid action. DESIGN Prospective cohort study. SETTING Academic medical center. PATIENT(S) Thirty-seven nonobese women underwent ovarian stimulation for in vitro fertilization (IVF). INTERVENTION(S) At oocyte retrieval, FF was aspirated from the first follicle (>16 mm in size) of each ovary and pooled CCs were collected. MAIN OUTCOME MEASURE(S) Follicular fluid cortisol and cortisone analysis was performed with the use of liquid chromatography-tandem mass spectrometry. CCs were stained with lipid fluorescent dye Bodipy FL C16 to determine lipid content with the use of confocal microscopy. Quantitative real-time polymerase chain reaction was used to detect CC gene expression of 11β-hydroxysteroid dehydrogenase (11β-HSD) types 1 and 2, glucocorticoid receptor (NR3C1), lipoprotein lipase (LPL), and hormone-sensitive lipase (HSL). RESULT(S) Adjusting for maternal age, FF cortisol levels negatively correlated with CC lipid content and positively correlated with numbers of total and mature oocytes. CCs expressed genes for 11β-HSD type 1 as the predominant 11β-HSD isoform, NR3C1, LPL, and HSL. CONCLUSION(S) FF cortisol levels may regulate CC lipolysis during oocyte meiotic resumption and affect oocyte quality during IVF.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common metabolic dysfunction and heterogeneous endocrine disorder in women of reproductive age. Although patients with PCOS are typically characterized by increased numbers of oocytes retrieved during IVF, they are often of poor quality, leading to lower fertilization, cleavage and implantation rates, and a higher miscarriage rate. METHODS For this review, we searched the database MEDLINE (1950 to January 2010) and Google for all full texts and/or abstract articles published in English with content related to oocyte maturation and embryo developmental competence. RESULTS The search showed that alteration of many factors may directly or indirectly impair the competence of maturating oocytes through endocrine and local paracrine/autocrine actions, resulting in a lower pregnancy rate in patients with PCOS. The extra-ovarian factors identified included gonadotrophins, hyperandrogenemia and hyperinsulinemia, although intra-ovarian factors included members of the epidermal, fibroblast, insulin-like and neurotrophin families of growth factors, as well as the cytokines. CONCLUSIONS Any abnormality in the extra- and/or intra-ovarian factors may negatively affect the granulosa cell-oocyte interaction, oocyte maturation and potential embryonic developmental competence, contributing to unsuccessful outcomes for patients with PCOS who are undergoing assisted reproduction.

Abstract
PURPOSE To assess the correlation of intrafollicular insulin, leptin and adiponectin levels with assisted reproductive technologies (ART) outcome. METHODS This was a retrospective study of 46 patients undergoing in vitro fertilisation/intracytoplasmic sperm injection. Follicular fluid (FF) samples collected at oocyte retrieval were assayed for insulin, leptin and adiponectin levels using enzyme-linked immunosorbent assay, and correlations with ART outcome were analysed. RESULTS There was no significant correlation between intrafollicular insulin, leptin and adiponectin levels. There was a significant difference in the concentration of insulin (P = 0.007), but not leptin or adiponectin, between pregnant (n = 20) and non-pregnant (n = 26) cycles. Only two pregnancies was observed in the 12 cycles in which the concentration of insulin was greater than 7 mU/l in FF, while 18 pregnancies was observed in the 34 cycles in which the concentration of insulin was less than 7 mU/l (P = 0.043). The significantly high concentration of insulin in FF was observed in non-pregnant cycles of patients with polycystic ovary syndrome (PCOS). CONCLUSIONS Our results suggest the possible involvement of intrafollicular insulin in folliculogenesis. Insulin resistance-related substances may affect the reproductive process in patients with PCOS.

Abstract
BACKGROUND Early prenatal androgenization (PA) accelerates follicle differentiation and impairs embryogenesis in adult female rhesus monkeys (Macaca mulatta) undergoing FSH therapy for IVF. To determine whether androgen excess in utero affects follicle development over time, this study examines whether PA exposure, beginning at gestational days 40-44 (early treated) or 100-115 (late treated), alters the decline in serum anti-Mullerian hormone (AMH) levels with age in adult female rhesus monkeys and perturbs their ovarian response to recombinant human FSH (rhFSH) therapy for IVF. METHODS Thirteen normal (control), 11 early-treated and 6 late-treated PA adult female monkeys had serum AMH levels measured at random times of the menstrual cycle or anovulatory period. Using some of the same animals, basal serum AMH, gonadotrophins and steroids were also measured in six normal, five early-treated and three late-treated PA female monkeys undergoing FSH therapy for IVF during late-reproductive life (>17 years); serum AMH also was measured on day of HCG administration and at oocyte retrieval. RESULTS Serum AMH levels in early-treated PA females declined with age to levels that were significantly lower than those of normal (P < or = 0.05) and late-treated PA females (P < or = 0.025) by late-reproductive life. Serum AMH levels positively predicted numbers of total/mature oocytes retrieved, with early-treated PA females having the lowest serum AMH levels, fewest oocytes retrieved and lowest percentage of females with fertilized oocytes that cleaved. CONCLUSIONS Based on these animals, early PA appears to program an exaggerated decline in ovarian reserve with age, suggesting that epigenetically induced hormonal factors during fetal development may influence the cohort size of ovarian follicles after birth.

Abstract
OBJECTIVE To investigate the relationship between antimüllerian hormone (AMH) and steroidogenesis in follicles of normoandrogenic ovulatory women undergoing follicle-stimulating hormone (FSH) therapy for in vitro fertilization/embryo transfer (IVF-ET). DESIGN Prospective cohort. SETTING Institutional/private practice. PATIENT(S) 26 normoandrogenic ovulatory women. All women received gonadotropin-releasing hormone (GnRH) analog and ovarian stimulation for IVF-ET. INTERVENTION(S) Follicle fluid was aspirated at oocyte retrieval from the first follicle of each ovary. MAIN OUTCOME MEASURE(S) Follicle fluid was assayed for AMH, estradiol (E(2)), progesterone, androstenedione, testosterone, dihydrotestosterone, insulin, and FSH. RESULT(S) Intrafollicular AMH levels positively and negatively correlated with E(2) and FSH concentrations in follicles, respectively, causing a positive relationship between follicle fluid AMH levels and E(2)/FSH ratios as a measure of follicle sensitivity to FSH. A positive relationship also existed in follicles between AMH levels and E(2)/androgen ratios as a marker of aromatase activity. CONCLUSION(S) The AMH levels in follicles of IVF patients positively correlate with follicle sensitivity to FSH.

Abstract
The prenatal testosterone (T)-treated adult female rhesus monkey is one animal model of polycystic ovary syndrome (PCOS) in women, with early prenatal T excess programming a permanent PCOS-like phenotype characterized by luteinizing hormone (LH) hypersecretion from reduced hypothalamic sensitivity to steroid negative feedback and relative insulin excess from increased abdominal adiposity. These combined reproductive and metabolic abnormalities are associated with ovarian hyperandrogenism and follicular arrest in adulthood, as well as premature follicle differentiation and impaired embryo development during gonadotropin therapy for in vitro fertilization (IVF). A second animal model for PCOS, the prenatal T-treated sheep also is characterized by LH hypersecretion from reduced hypothalamic sensitivity to steroid negative feedback, persistent follicles and insulin resistance, but also is associated with intrauterine growth retardation and compensatory growth after birth. The ability of prenatal T excess in both species to alter the developmental trajectory of multiple organ systems in utero provides evidence that the hormonal environment of intrauterine life programs target tissue differentiation, raising the possibility that T excess in human fetal development promotes PCOS in adulthood. Such a hypothesis must include data from clinical studies of PCOS women to clarify the homology between these PCOS-like animal models and PCOS per se in reproductive and metabolic function. Future studies should develop new clinical strategies that improve pregnancy outcome and minimize pregnancy loss in women with disorders of insulin action, including PCOS, obesity and diabetes mellitus as well as minimize transgenerational susceptibility to adult PCOS and its metabolic derangements in male close relatives.

Abstract
OBJECTIVE To explore the importance of follicle-stimulating hormone receptor (FSHR) in granulosa cells in the ovarian response to gonadotropin stimulation. DESIGN Prospective study. SETTING A women's hospital in China. PATIENT(S) One hundred infertile women undergoing ovarian stimulation with recombinant follicle-stimulating hormone (rFSH). INTERVENTION(S) These women were divided into three groups: poor, moderate, and high responders, according to the number of follicles with diameter >/=14 mm. The FSHR expression at both mRNA and protein levels was determined by either reverse transcription-polymerase chain reaction or Western blot in granulosa cells. E(2) concentrations in serum and FSH levels in serum/follicular fluid (FF) were measured by electrochemiluminescence immunoassay. MAIN OUTCOME MEASURE(S) Relative expression of mRNA and protein of FSHR in granulosa cells, serum E(2), FSH level in serum and FF, and the number of mature follicles. RESULT(S) The expression of FSHR, at both the mRNA and protein levels, was significantly different among the three groups, with the lowest expression in the poor responders. The level of FSHR protein was positively correlated with the peak level of serum E(2) and the number of mature oocytes. FSH levels in FF and the dosage of rFSH used were significantly different among the three groups, with the highest values in the poor responders. CONCLUSION(S) Different levels of FSHR expression in granulosa cells result in different ovarian response, and lower expression of FSHR may account for poor ovarian response to gonadotropin stimulation, which suggests the critical role of FSHR in the ovarian response to gonadotropin stimulation.

Abstract
Background: Steroid levels have been used as the predictive parameters for oocyte maturation and embryo development. In the present study, estradiol and progesterone concentrations in the follicular fluid and serum were evaluated in conventional in vitro fertilization (IVF; follicle stimulating hormone [FSH] and/or human menopausal gonadotropin [hMG] after pituitary desensitization) and friendly IVF (no stimulation, clomiphene citrate, small dose of FSH or hMG without pituitary desensitization). The purpose of the present study was to evaluate the differences in steroid distribution between conventional and friendly IVF. Methods: Concentrations of estradiol, progesterone, FSH, and luteinizing hormone (LH) in serum and follicular fluid were determined in conventional and friendly IVF protocols by an enzyme-linked immunosorbent assay kit. Correlations between follicular fluid and serum steroid concentrations in these different protocols, and between pregnant cycles and steroid concentrations were evaluated. Results: Two hundred and thirty-four samples of follicular fluid from 74 IVF patients were analyzed. In conventional IVF, there was no relationship in steroid levels in between follicular fluid and serum steroids, whereas serum steroid concentrations correlated with the number of developing follicles. There was a relationship between the serum and follicular fluid estradiol levels (r = 0.467, P < 0.0001) as well as progesterone levels (r = 0.227, P = 0.0488) from friendly IVF patients. Conclusions: Serum steroid concentrations were mainly associated with the number of developing follicles. In the cases of friendly IVF, which had a small number of developing follicles, serum steroids might be used to monitor follicular fluid steroid concentrations. (Reprod Med Biol 2006; 5: 277-282).

Abstract
Luteinizing hormone is now available as the recombinant product, lutropin alfa for the treatment of female infertility. It is necessary in the natural process of follicular growth and maturation. It is not yet clear which patients really benefit from the addition of this medication to conventional gonadotropin stimulation procedures in infertility treatment. Certainly, it has a proven benefit in patients suffering from hypogonadotropic hypogonadism (WHO I). Others may be older patients, patients with a profound gonadotropin suppression stimulated in long gonadotropin-releasing hormone agonist protocols, or patients with poor ovarian response to conventional stimulation strategies. The available data are reviewed herein.
