Abstract
A significant number of single-nucleotide polymorphisms (SNPs) of the follicle-stimulating hormone receptor (FSHr) can modify the response to exogenous FSH administration. A significant diversity in response to controlled ovarian stimulation (COS) in assisted reproductive technologies (ART) according to the type of allelic has been reported. We aimed to evaluate the relation between the Asn680Ser allelics and COS. A total of 4 electronic databases were searched for articles published up to August 2021. Prospective and retrospective comparative studies which reported outcomes after COS in patients who underwent genotyping for the detection of FSHr polymorphisms were considered eligible. A total of 11 studies including 4343 patients with Asn680Ser polymorphisms of the FSHr were included. Patients carrying the Asn/Asn allelic provide elevated E2 on the day of human chorionic gonadotropin (hCG) administration (1549 patients MD 262.39 pg/ml, p = 0.0007), but less transferrable embryos as compared with Ser/Ser genotype (283 patients MD - 0.11 embryos, p = 0.04). Ans/Ser versus Ser/Ser genotypes showed a higher E2 on the day of hCG administration (1799 patients, MD 207.86 pg/ml, p = 0.02). Pregnancy rates were similar in all combination of genotypes. There is currently no strong evidence suggesting that the examination of one gene in relation to genotypes can be effectively used as single tool to improve COS. However, polygenic analysis of different polymorphisms by analyzing the genetic profile of each individual could be useful. Further research is warranted to develop an algorithm that will enable simultaneous analysis of many genes, which combined with hormonal profile could promote treatment individualization.

[PMID: 35351379 DOI: 10.1016/j.rbmo.2021.12.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 12/21/2021] [Accepted: 12/22/2021] [Indexed: 11/15/2022]
Abstract
RESEARCH QUESTION What is the influence of ethnicity on the outcome of ovulation induction with clomifene citrate in women with polycystic ovary syndrome (PCOS)? DESIGN This was a retrospective cohort study. In total, 420 women diagnosed with PCOS who were of Northern European, Mediterranean, African, South-East Asian or South American descent, and who started ovulation induction treatment with clomifene citrate, were included. All women were treated with clomifene citrate according to a standardized treatment regimen. The minimal effective dose of clomifene citrate and prevalence of clomifene resistance (CRA) were assessed, and the chance of becoming ovulatory was predicted. RESULTS Differences were observed in body mass index (P = 0.008), waist circumference (P = 0.036) and serum LH, insulin and androgen concentrations (all P < 0.001) in women of different ethnicities with PCOS. Compared with women of Northern European descent, the minimal effective dose of clomifene citrate in women of other ethnic groups was not significantly different. The prevalence of CRA (P = 0.574) was similar in all ethnic groups A similar chance of ovulation (P = 0.504) was predicted for the different ethnic groups. CONCLUSIONS This is the first study aiming to link ethnicity to ovulation induction outcome in PCOS. Although women of different ethnicities who have PCOS exhibit a variation in phenotypic expression, there do not appear to be differences in the prevalence of clomifene-resistant anovulation or the minimal effective dose of clomifene citrate. Furthermore, a prediction model revealed no significant differences in the predicted chance of ovulation. A larger cohort is needed to validate these findings.

Abstract
PURPOSE To determine the influence of different genotypes of Ala307Thr and Asn680Ser FSHr polymorphisms on controlled ovarian stimulation (COS) outcome and pregnancy. METHODS This study collected blood and physiological and clinical parameters of 517 Caucasian patients (Statistical power ≥ 80%) that underwent COS treatment. Genotypes of Ala307Thr and Asn680Ser polymorphisms were determined using PCR amplification followed by Bsu36I and BsrI digestion, respectively. RESULTS Ala307Ala and Ser680Ser genotypes associated to worse parameters of COS outcome (preovulatory follicles P = 0.05, in both), justifying their lower pregnancy rate than Non-Ala307Ala, P = 0.01 and Non-Ser680Ser, P = 0.004, respectively or together, (P = 0.003). Within the Non-Ala307Ala group, Thr307Thr genotype showed higher number of fertilized oocytes (P = 0.04) and embryos (P = 0.01) than Non-Thr307Thr, but no influence on pregnancy rate. Ala307Ala and Ser680Ser patients doubled probability of non-pregnancy than Non-Ala307Ala (odds ratio = 2.0) and Non-Ser680Ser (odds ratio = 2.11), respectively. Ala307Ala and Ser680Ser genotypes tend to appear together (P < 0.0001), which increases the probability of non-pregnancy. CONCLUSIONS Ala307Ala and Ser680Ser genotypes of 307 and 680 FSHr polymorphisms associate to worse COS outcome than its respective Non-Ala307Ala and Non-Ser680Ser. Within the Non-Ala307Ala genotypes, Thr307Thr, although shows higher Fertilized Oocytes and Embryos, do not influence on pregnancy rate. Ala307Ala and Ser680Ser genotypes double the probability of Non-Pregnancy than their respective Non-Ala307Ala and Non-Ser680Ser genotypes. Furthermore, the strong tendency of these genotypes to appear together worsens the probability of pregnancy in these patients.

Abstract
BACKGROUND AND AIMS Female infertility is a complex multifactorial, and polygenic disease associated with genetic factors plays an essential role in its formation and follicle development, oocyte maturation, and steroidogenesis regulation in the ovary. The aim here is too study the genetic association between follicle-stimulating hormone receptor (FSHR) Asn680Ser; (rs6166) gene polymorphism with female Infertility in our population. METHODS In this prospective case-control study, we enrolled 106 infertile and 164 unrelated healthy control individuals. Genomic DNA was extracted from the 5 ml of venous blood using the modified salting-out method. A polymerase chain reaction-amplified exon 10 of FSHR and purified PCR products were sequenced on an ABI 3730XL DNA sequencer. The data were analyzed statistically. RESULTS We found that the presence of rare allele "G" and heterozygous and common homozygous genotypes significantly increased the risk of female infertility. No significant change in the FSHR 191756 G >A genotype frequency was observed, regardless of chromosomal integrity. The genotype frequency distribution of locus 680 was consistent with the Hardy-Weinberg Equilibrium (HWE) in both groups (P > 0.05). CONCLUSION No significant differences were found in allelic variants frequency and genotype distribution between each category of subjects when analyzing the FSHR SNPs in the exonic region (P value >0.05). FSHR Asn680Ser polymorphisms and female infertility (P > 0.05). Variations in FSHR gene have an essential influence on ovarian function and can account for several defects of female fertility. FSHR Asn680Ser (rs6166) gene polymorphism is associated with female infertility and can be used as a relevant molecular biomarker to identify the risk of infertility in our population. This finding can be important for disease pathogenesis.

Abstract
BACKGROUND FSHR SNPs may influence the ovarian sensitivity to endogenous and exogenous FSH stimulation. Given the paucity of data on the FSHR c.919A > G, c.2039A > G and - 29G > A SNPs in Hispanic population, we here analyzed their frequency distribution in Mexican mestizo women. METHODS Samples from 224 Mexican mestizo women enrolled in an IVF program as well as a genotype database from 8182 Mexican mestizo subjects, were analyzed for FSHR SNPs at positions c.919, c.2039 and - 29G > A. Association between the genetic variants and reproductive outcomes was assessed. RESULTS The c.919 and c.2039 SNPs were in strong linkage disequilibrium and their corresponding genotype frequencies in the IVF group were: AA 46.8%, AG 44.2%, and GG 8.9%, and AA 41.9%, AG 48.2% and GG 9.8%, respectively. For the -29G > A SNP, genotype frequencies were 27% (GG), 50% (GA) and 23% (AA). In normal oocyte donors with the c.2039 GG genotype, the number of oocytes recovered after ovarian stimulation (COS) were significantly (p < 0.01) lower than in those bearing other genotypes in this or the -29G > A SNP. Analysis of the large scale database revealed that both allelic and genotype frequencies for the three SNPs were very similar to those detected in the IVF cohort (p ≥ 0.38) and that female carriers of the c.2039 G allele tended to present lower number of pregnancies than women bearing the AA genotype; this trend was stronger when women with more Native American ancestry was separately analyzed (OR = 2.0, C.I. 95% 1.03-3.90, p = 0.04). There were no differences or trends in the number of pregnancies among the different genotypes of the -29G > A SNP. CONCLUSIONS The frequency of the GG/GG combination genotype for the c.919 and c.2039 SNPs in Mexican hispanics is among the lowest reported. The GG genotype is associated with decreased number of oocytes recovered in response to COS as well as to lower pregnancy rates in Hispanic women from the general population. The absence of any effect of the -29AA genotype on the response to COS, indicates that there is no need to perform this particular genotype testing in Hispanic women with the purpose of providing an individually-tailored COS protocol.
