Association of LHCGR rs2293275 genotype with ovarian aging in Chinese women: a multicenter population-based study. Reprod Biol Endocrinol 2025; 23:41. [PMID: 40089715 PMCID: PMC11909885 DOI: 10.1186/s12958-025-01375-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2024] [Accepted: 03/02/2025] [Indexed: 03/17/2025] Open
Abstract
OBJECTIVE To evaluate the association between the LHCGR rs2293275 (N312S) genotype and ovarian aging phenotypes in Han Chinese women, focusing on diminished ovarian reserve (DOR) and primary ovarian insufficiency (POI). STUDY DESIGN This multicenter population-based study included 1,240 women aged 18-40 years diagnosed with DOR (n = 711) or POI (n = 529), alongside 72,846 ethnically and regionally matched controls from the Han Chinese Genomes Database (PGG.Han). Genotyping of rs2293275 was performed, and clinical data (menstrual history, hormonal profiles, maternal menopause age, and ART outcomes) were analyzed. MAIN RESULTS The AA genotype frequency in the ovarian aging cohort (1.85%) was significantly higher than in the general Han population (0.62%, OR 3.04, 95% CI 1.99-4.64, p < 0.001). AA carriers exhibited earlier POI diagnosis (25.5 ± 6.4 vs. 32.0 ± 5.1 years in GG carriers, p < 0.001) and maternal menopause (41.6 ± 3.3 vs. 47.8 ± 4.1 years, p < 0.001). In controlled ovarian stimulation cycles, AA carriers demonstrated reduced ovarian sensitivity (OSI: 3.59 vs. 1.21 in GG, p = 0.019) despite comparable gonadotropin doses. CONCLUSIONS The LHCGR rs2293275 AA genotype is strongly associated with accelerated ovarian aging in Han Chinese women, highlighting its potential as a biomarker for early identification of high-risk individuals. While these findings underscore genetic contributions to ovarian dysfunction, further mechanistic studies are needed to establish causality and optimize clinical translation.

Abstract
Luteinizing hormone (LH) is fundamental to support development and reproduction. It acts through a receptor expressed in the gonads, modulating mitogenic, anti-apoptotic, and steroidogenic signals. LH is also marketed as a drug for controlled ovarian stimulation (COS), where it is administered to women to support the action of follicle-stimulating hormone and can lead to specific responses, depending on the individual genetic background. These concepts underline the relevance of a pharmacogenetic approach to COS, in the attempt to optimize clinical outcomes and avoid adverse events. However, knowledge is currently limited by the paucity of clinical studies. This review aims to provide a comprehensive overview of LH and its receptor activity, starting from the description of their molecular pathways from in vitro studies. Data on LH action from in vivo studies were described, as well as the impact of LH and LH/choriogonadotropin (hCG) receptor genetic variants on folliculogenesis and its association with infertility or polycystic ovarian syndrome. Finally, evidence from clinical studies evaluating genetic polymorphisms in the context of assisted reproductive technology treatments and its implications for a pharmacogenomic approach were discussed.

Luteinizing Hormone Receptor Mutation (LHR N316S) Causes Abnormal Follicular Development Revealed by Follicle Single-Cell Analysis and CRISPR/Cas9. Interdiscip Sci 2024; 16:976-989. [PMID: 39150470 PMCID: PMC11512921 DOI: 10.1007/s12539-024-00646-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 07/17/2024] [Accepted: 07/22/2024] [Indexed: 08/17/2024]
Abstract
Abnormal interaction between granulosa cells and oocytes causes disordered development of ovarian follicles. However, the interactions between oocytes and cumulus granulosa cells (CGs), oocytes and mural granulosa cells (MGs), and CGs and MGs remain to be fully explored. Using single-cell RNA-sequencing (scRNA-seq), we determined the transcriptional profiles of oocytes, CGs and MGs in antral follicles. Analysis of scRNA-seq data revealed that CGs may regulate follicular development through the BMP15-KITL-KIT-PI3K-ARF6 pathway with elevated expression of luteinizing hormone receptor (LHR). Because internalization of the LHR is regulated by Arf6, we constructed LHRN316S mice by CRISPR/Cas9 to further explore mechanisms of follicular development and novel treatment strategies for female infertility. Ovaries of LHRN316S mice exhibited reduced numbers of corpora lutea and ovulation. The LHRN316S mice had a reduced rate of oocyte maturation in vitro and decreased serum progesterone levels. Mating LHRN316S female mice with ICR wild type male mice revealed that the infertility rate of LHRN316S mice was 21.4% (3/14). Litter sizes from LHRN316S mice were smaller than those from control wild type female mice. The oocytes from LHRN316S mice had an increased rate of maturation in vitro after progesterone administration in vitro. Furthermore, progesterone treated LHRN316S mice produced offspring numbers per litter equivalent to WT mice. These findings provide key insights into cellular interactions in ovarian follicles and provide important clues for infertility treatment.

Abstract
The present prospective cohort study evaluated the prevalence of FSH-R receptor Asn680Ser and Ala307Thr among infertile Indian women and the correlation of these polymorphisms with ART outcomes. Total 804 infertile and 209 fertile controls were enrolled for FSH-R analysis. Correlation of different genotypes with ovarian reserve markers, IVF parameters, and cumulative live birth rates (CLBR) was done among women undergoing IVF. In fertile controls, at 680 position GG (Ser/Ser) was the most common genotype; but among infertile women, all the genotypes were equally distributed. There was no significant difference in ovarian response parameters, oocyte yield, and CLBR among the three genotype groups. Empty follicle syndrome (EFS) was highest in women with AA or AG type at both positions. On categorisation of unexpected poor responders according to POSEIDON stratification; GG genotype at both positions had the lowest risk ratio of low-oocyte yield in ART cycles, but these differences were not statistically significant. This is the largest study from Indian ethnicity showing GG (Ser/Ser) genotype is most common among fertile women. The effect of FSH-R genotypes is very marginal on IVF parameters and is not reflected in CLBR. More prospective data may be required on the correlation of these genotypes with genuine EFS, thus stratifying the next cycles with self or donor oocytes. Routine genetic testing of FSH-R polymorphism should not be done except in a research setting. As both 680 and 307 positions are in linkage disequilibrium, only 680 position analysis may be done in a research setting.

Significance of FSHR and LHCGR gene polymorphisms on clinical outcomes in gonadotropin-releasing hormone antagonist protocol with freeze-all strategy: A case-control study. Int J Reprod Biomed 2024; 22:539-552. [PMID: 39355311 PMCID: PMC11441282 DOI: 10.18502/ijrm.v22i7.16962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 03/05/2024] [Accepted: 04/29/2024] [Indexed: 10/03/2024] Open
Abstract
Background Follicle-stimulating hormone receptor (FSHR) and luteinizing hormone/choriogonadotropin receptor (LHCGR) are integral to ovarian function, facilitating follicle development and maturation through their respective hormonal interactions. The influence of receptor polymorphisms on the outcomes of freeze-all cycles remains unclear. Objective This study investigates the impact of FSHR N680S and LHCGR N312S polymorphisms on clinical outcomes in freeze-all cycles. Materials and Methods Women undergoing controlled ovarian stimulation for assisted reproductive technology participated in this study. They were administered a gonadotropin-releasing hormone antagonist protocol, with recombinant follicle-stimulating hormone (rFSH) dosages adjusted according to age, body mass index, antral follicle count, and individual hormonal responses. Additionally, human menopausal gonadotropin dosages were tailored based on the LHCGR N312S genetic variant. Results Analysis revealed no significant differences in age, body mass index, antral follicle count, or marital status across the genotypes of FSHR N680S and LHCGR N312S. However, notable differences were observed in the rFSH dosage required daily and in total among the FSHR polymorphism genotypes. Genotypes of the LHCGR polymorphism correlated with fewer stimulation days. A significant interaction was observed between the 2 polymorphisms concerning total rFSH dosage. Conclusion The presence of serine in the FSHR polymorphism was associated with higher rFSH dosage requirements. Both FSHR N680S and LHCGR N312S polymorphisms significantly influenced clinical pregnancy and live birth outcomes in freeze-all cycles, underscoring the potential of a pharmacogenomic approach to optimize hormone supplementation in controlled ovarian stimulation protocols during assisted reproductive technology treatments.

Liu S, Ma S, Li Y. The average gonadotrophin dosage per follicle is predictive of ovarian response and cumulative live birth chances after in vitro fertilization: a retrospective cohort study. BMC Womens Health 2023; 23:45.

Abstract
BACKGROUND With the development of assisted reproduction technology (ART), many indicators have been proposed to evaluate ovarian response, and then predict pregnancy outcomes. In general, the predictive values remain limited. OBJECTIVE To further explore the indicators to evaluate ovarian sensitivity to gonadotrophin (Gn) stimulation more accurately. METHODS This retrospective cohort study included 330 women who underwent an entire ART cycle. We aimed to assess whether a new index, termed as average Gn dosage per follicle, could be used as a marker for ovarian response and pregnancy outcomes. It was calculated as the ratio of total Gn dose during ovarian stimulation and the number of pre-ovulatory follicles (PFC) on the trigger day. Patients were divided into three subgroups according to the average Gn dosage per follicle: below the 33rd percentile (Group A), between 33rd and 67th percentiles (Group B), and above the 67th percentile (Group C). Then stimulation data, laboratory and clinical outcomes were compared among the groups. RESULTS The results showed patients in Group A had the best ovarian response, the number of retrieved oocytes was significantly higher than in Group B and C. A multivariate regression analysis showed that average Gn dosage per follicle was an independent predictor of cumulative live birth rates (CLBRs) [adjusted odds ratio (OR): 0.96, 95% confidence interval (CI): 0.95-0.98, P < 0.01]. CONCLUSIONS The present study showed that average Gn dosage per follicle appears to be a highly reliable index of ovarian response to exogenous Gn and can be useful to estimate CLBR.

Abstract
OBJECTIVE To study the effect of Guilu Erxian ointment on the outcome of IVF-ET in older patients with poor ovarian response infertility of kidney-qi deficiency type, and to verify and analyze the mechanism of action of traditional Chinese medicine on improving older patients with poor ovarian response infertility of kidney-qi deficiency type from the perspective of metabolomics using targeted metabolomics technology, identify the related metabolic pathways, and provide metabolic biomarker basis and clinical treatment ideas for improving older patients with poor ovarian response infertility. METHODS This study was a double-blind, randomized, placebo-controlled trial, and a total of 119 infertile patients who underwent IVF-ET at Shandong Center for Reproduction and Genetics of Integrated Traditional Chinese and Western Medicine were selected. Eighty older patients with infertility undergoing IVF were randomly divided into older treatment group and older placebo group, and another 39 young healthy women who underwent IVF-ET or ICSI due to male factors were selected as the normal control group. Flexible GnRH antagonist protocol was used for ovulation induction in all three groups, and Guilu Erxian ointment and placebo groups started taking Guilu Erxian ointment and placebo from the third day of menstruation until IVF surgery. And ultra-high performance liquid chromatography-triple quadrupole mass spectrometer (UHPLC-QTRAP MS) was used to detect metabolites in the three groups of samples. RESULTS Compared with the placebo group, the number of oocytes retrieved, 2PN fertilization, high-quality embryos, total number of available embryos and estrogen on HCG day were increased in the treatment group, and the differences were statistically significant (P > 0.05), but the clinical pregnancy rate of fresh embryos and frozen embryos were not statistically significant (P > 0.05). The results of targeted metabolomics analysis showed that follicular fluid in the treatment group clustered with the normal young group and deviated from the placebo group. A total of 55 significant differential metabolites were found in the follicular fluid of older patients with poor ovarian response of kidney-qi deficiency type and patients in the normal young group, after Guilu Erxian ointment intervention, Metabolites such as L-Aspartic acid, Glycine, L-Serine, Palmitoleic Acid, Palmitelaidic acid, L-Alanine, Gamma-Linolenic acid, Alpha-Linolenic Acid, and N-acetyltryptophan were down-regulated, mainly involving amino acid metabolism and fatty acid metabolism. CONCLUSION Guilu Erxian ointment can effectively improve the clinical symptoms and IVF outcomes of older patients with poor ovarian response of kidney-qi deficiency type. There were differences in follicular fluid metabolites between older patients with poor ovarian response of kidney-qi deficiency type and normal women. L-Aspartic acid, L-Alanine, Aminoadipic acid, L-Asparagine, L-Arginine, L-Serine, Gamma- Linolenic acid, Pentadecanoic acid and Alpha-Linolenic Acid are closely related to older patients with poor ovarian response due to deficiency of kidney-qi and may be inferred as biomarkers. The mechanism of Guilu Erxian ointment intervention may be mainly through amino acid metabolism and fatty acid metabolism regulation.

Abstract
Background Choriogonadotropin (CG) beta (FE 999302), a novel recombinant human (h)CG produced by a human cell line, has a longer half-life and higher potency than CG alfa produced by a Chinese hamster ovary cell line. hCG augments steroid production, but the extent of which CG beta treatment during ovarian stimulation (OS) increases steroidogenesis is unknown. Objective To explore how increasing doses of CG beta during OS augment follicular steroidogenesis and change gene expression in cumulus cells. Study design This study is part of a randomized, double-blind, placebo-controlled trial to investigate the efficacy and safety of CG beta plus recombinant follicle-stimulating hormone (rFSH) in women undergoing OS during a long gonadotrophin-releasing hormone agonist protocol. The study primary endpoint was intrafollicular steroid concentrations after CG beta administration. Secondary outcomes were gene expression of FSHR , LHR, CYP19a1, and androgen receptor (AR). Participants/methods 619 women with anti-Müllerian hormone levels 5-35 pmol/L were randomized to receive placebo or 1, 2, 4, 8, or 12 µg/day CG beta from Day 1 of OS plus rFSH. Follicular fluid (FF) (n=558), granulosa (n=498) and cumulus cells (n=368) were collected at oocyte retrieval. Steroid FF hormones were measured using enzyme-linked immunosorbent assays, gene expression was analyzed in cumulus cells by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and single nucleotide polymorphism (SNP) analysis was performed in granulosa cells. Results 17-OH-progesterone, androstenedione, testosterone, and estradiol concentrations significantly increased in a CG-beta dose-dependent manner during OS (p<0.0001), reaching up to 10 times higher values in the highest dose group versus placebo. There was no difference between CG beta dose groups and placebo for progesterone. Expression levels of CYP19a1 increased significantly in the highest dose group of CG beta (p=0.0325) but levels of FSHR , LHR and AR were not affected by CG beta administration. There were no differences between the FSHR (307) or LHR(312) SNP genotypes for dose-dependent effects of CG beta in relation to number of oocytes, intrafollicular steroid hormone levels, or gene expression levels. Conclusions These results reflect the importance of the combined effect of FSH and hCG/LH during OS on granulosa cell activity, follicle health and potentially oocyte quality. Trial Registration number 2017-003810-13 (EudraCT Number). Trial Registration date 21 May 2018. Date of first patient’s enrolment 13 June 2018.

Gonadotropin receptor polymorphisms (FSHR N680S and LHCGR N312S) are not predictive of clinical outcome and live birth in assisted reproductive technology. Fertil Steril 2022; 118:494-503. [PMID: 35842313 DOI: 10.1016/j.fertnstert.2022.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 06/13/2022] [Accepted: 06/13/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To study the consequences of specific genotype profiles of follicle-stimulating hormone receptor (FSHR) and luteinizing hormone choriogonadotropin receptor (LHCGR) on assisted reproductive technology outcomes when preimplantation genetic testing for aneuploidy is used for controlling the embryo ploidy status. The most common reported single-nucleotide polymorphisms in the amino acid position for the FSHR (N680S; N: asparagine, S: serine; [rs6166]) and the LHCGR (N312S variant; N: asparagine, S: serine [rs2293275]) were chosen for this study. DESIGN Retrospective cohort study. SETTING Private Fertility Clinic. PATIENT(S) All women aged 18-40 years undergoing their first assisted reproductive technology cycle with aneuploidy screening between 2006 and 2017 with body mass index of >18 and <40 kg/m2 were included. INTERVENTION(S) All patients received both recombinant follicle-stimulating hormone and human menopausal gonadotropin or low dose human chorionic gonadotropin. Genomic DNA was isolated from patients' blood. Genotyping of the FSHR and LHCGR polymorphisms was performed using TaqMan genotyping assays. Associations between both receptor genotypes and clinical outcomes were assessed using generalized regression and ANOVA. MAIN OUTCOMES MEASURE(S) Live birth rate was the primary outcome. Secondary outcomes included oocyte yield, mature oocytes, blastulation rate, usable blastocyst rate, and implantation rate. RESULT(S) A total of 1,183 patients met the inclusion criteria and generated reliable genotype results. The overall genotype frequencies in the study population for the FSHR gene were as follows: 21.7% homozygous for S in codon 680, 29.2% homozygous for N680, and 48.1% heterozygous (N680S). As for the LHCGR, 15.6% were homozygous for N312, 38.5% homozygous for S312 and 45.9% heterozygous (N312S). Our study population consisted of 53.8% non-Hispanic white; 6.1% Hispanic white; 4.1% Afro-American; 15.4% Asian; and 20.6% other or unknown. No significant association was found with any of the studied variables (oocyte yield, usable blastocyst rate, implantation rate, live birth) when genotypes were analyzed per receptor or in combination with one another. There was a statistically significant but clinically irrelevant difference in the rate of mature oocytes across different variant combinations. CONCLUSION(S) Our findings suggest that the presence of gonadotropin receptor polymorphisms in both FSHR N680S and LHCGR N312S are not associated with assisted reproductive technology outcomes; therefore, these variants should not be considered reproductive predictors.

Effect of Genetic Variants of Gonadotropins and Their Receptors on Ovarian Stimulation Outcomes: A Delphi Consensus. Front Endocrinol (Lausanne) 2022; 12:797365. [PMID: 35178027 PMCID: PMC8844496 DOI: 10.3389/fendo.2021.797365] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 12/15/2021] [Indexed: 01/20/2023] Open
Abstract
Background A Delphi consensus was conducted to evaluate the influence of single nucleotide polymorphisms (SNPs) in genes encoding gonadotropin and gonadotropin receptors on clinical ovarian stimulation outcomes following assisted reproductive technology (ART) treatment. Methods Nine experts plus two Scientific Coordinators discussed and amended statements plus supporting references proposed by the Scientific Coordinators. The statements were distributed via an online survey to 36 experts, who voted on their level of agreement or disagreement with each statement. Consensus was reached if the proportion of participants agreeing or disagreeing with a statement was >66%. Results Eleven statements were developed, of which two statements were merged. Overall, eight statements achieved consensus and two statements did not achieve consensus. The statements reaching consensus are summarized here. (1) SNP in the follicle stimulating hormone receptor (FSHR), rs6166 (c.2039A>G, p.Asn680Ser) (N=5 statements): Ser/Ser carriers have higher basal FSH levels than Asn/Asn carriers. Ser/Ser carriers require higher amounts of gonadotropin during ovarian stimulation than Asn/Asn carriers. Ser/Ser carriers produce fewer oocytes during ovarian stimulation than Asn/Asn or Asn/Ser carriers. There is mixed evidence supporting an association between this variant and ovarian hyperstimulation syndrome. (2) SNP of FSHR, rs6165 (c.919G>A, p.Thr307Ala) (N=1 statement): Few studies suggest Thr/Thr carriers require a shorter duration of gonadotropin stimulation than Thr/Ala or Ala/Ala carriers. (3) SNP of FSHR, rs1394205 (-29G>A) (N=1 statement): Limited data in specific ethnic groups suggest that A/A allele carriers may require higher amounts of gonadotropin during ovarian stimulation and produce fewer oocytes than G/G carriers. (4) SNP of FSH β-chain (FSHB), rs10835638 (-211G>T) (N=1 statement): There is contradictory evidence supporting an association between this variant and basal FSH levels or oocyte number. (5) SNPs of luteinizing hormone β-chain (LHB) and LH/choriogonadotropin receptor (LHCGR) genes (N=1 statement): these may influence ovarian stimulation outcomes and could represent potential future targets for pharmacogenomic research in ART, although data are still very limited. Conclusions This Delphi consensus provides clinical perspectives from a diverse international group of experts. The consensus supports a link between some variants in gonadotropin/gonadotropin receptor genes and ovarian stimulation outcomes; however, further research is needed to clarify these findings.

Does Follicle-Stimulating hormone receptor polymorphism status affect In vitro fertilization-intracytoplasmic sperm injection results and live birth rate? A retrospective study. J Hum Reprod Sci 2022; 15:58-63. [PMID: 35494202 PMCID: PMC9053349 DOI: 10.4103/jhrs.jhrs_165_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 02/05/2022] [Accepted: 02/07/2022] [Indexed: 11/22/2022] Open
Abstract
Background: Follicle-stimulating hormone (FSH) plays a key role in fertility and shows its effect through the FSH receptor (FSHR), which is localized in cells. Aims: The aim of this study was to examine pregnancy outcomes and responses to controlled ovarian stimulation according to FSHR polymorphism types. Study Setting and Design: The study was retrospective, and included patients who applied to the University of Health Sciences Tepecik Training and Research Hospital in vitro fertilization (IVF) Unit during 2018 and 2019. Materials and Methods: Patients who underwent IVF-intracytoplasmic sperm injection and at the same time studied FSHR gene polymorphism in the genetic unit of our hospital were included in the study. Statistical Analysis: The Kruskal–Wallis test was used for multiple comparisons of continuous variables. The Chi-square test was used for categorical variables between groups. Results: A total of 143 patients who met our criteria were included in the study. 14% (n = 20) of the patients are also homozygous natural (Asn/Asn) type; 44.7% (n = 64) of the heterozygous mutant (Asn/Ser) type; 41.3% (n = 59) of them were homozygous mutant (Ser/Ser) type. There was no statistically significant difference between the groups in terms of pregnancy rate per started cycle, ongoing pregnancy per started cycle, ongoing pregnancy per embryo transfer and live birth per embryo transfer. A significant difference was observed between peak E2 and peak progesterone levels between Asn/Ser and Ser/Ser groups, and the levels of these hormones were lower in the Ser/Ser group (P = 0.018 and P = 0.016, respectively). Ovarian responses were classified as poor (≤3 oocytes), normal (4-20 oocytes) and hyperresponse (≥20 oocytes) according to the oocyte count. Accordingly, the number of patients with poor response was higher in the Ser/Ser group (P = 0.011). Conclusions: Ser/Ser polymorphism is characterised by a poor ovarian response. Despite this, polymorphisms in the FSHR gene do not seem to affect the results of pregnancy per started cycle, ongoing pregnancy per started cycle, ongoing pregnancy per embryo transfer and live birth per embryo transfer.

Abstract
This narrative review is concerned with genetic variants of the genes encoding gonadotrophin subunits and their receptors, as well as their implications into the diagnosis and treatment of infertility. We first review briefly the basics of molecular biology and biochemistry of gonadotrophin and gonadotrophin receptor structure and function, then describe the phenotypic effects of polymorphisms and mutations of these genes, followed by diagnostic aspects. We will then summarise the information that inactivating gonadotrophin receptor mutations have provided about the controversial topic of extragonadal gonadotrophin action. Finally, we will close with the current and future therapeutic approaches on patients with gonadotrophin and their receptor mutations.

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
Signal transduction by luteinizing hormone receptors (LHRs) and follicle-stimulating hormone receptors (FSHRs) is essential for the successful reproduction of human beings. Both receptors and the thyroid-stimulating hormone receptor are members of a subset of G-protein coupled receptors (GPCRs) described as the glycoprotein hormone receptors. Their ligands, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and a structurally related hormone produced in pregnancy, human chorionic gonadotropin (hCG), are large protein hormones that are extensively glycosylated. Although the primary physiologic functions of these receptors are in ovarian function and maintenance of pregnancy in human females and spermatogenesis in males, there are reports of LHRs or FSHRs involvement in disease processes both in the reproductive system and elsewhere. In this review, we evaluate the aggregation state of the structure of actively signaling LHRs or FSHRs, their functions in reproduction as well as summarizing disease processes related to receptor mutations affecting receptor function or expression in reproductive and non-reproductive tissues. We will also present novel strategies for either increasing or reducing the activity of LHRs signaling. Such approaches to modify signaling by glycoprotein receptors may prove advantageous in treating diseases relating to LHRs or FSHRs function in addition to furthering the identification of new strategies for modulating GPCR signaling.

Could polymorphisms of some hormonal receptor genes, involved in folliculogenesis help in predicting patient response to controlled ovarian stimulation? J Assist Reprod Genet 2019; 36:47-55. [PMID: 30406448 PMCID: PMC6338606 DOI: 10.1007/s10815-018-1357-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Accepted: 10/22/2018] [Indexed: 01/21/2023] Open
Abstract
PURPOSE The aim of this study was to investigate whether single nucleotide polymorphisms (SNPs) in selected genes, responsible for hormonal regulation of folliculogenesis, are associated with response to controlled ovarian hyperstimulation (COH) and clinical characteristics of women enrolled in in vitro fertilization (IVF) programs. METHODS In a cross-sectional study, 60 (IVF) patients underwent COH by using gonadotropin-releasing hormone (GnRH) antagonist and recombinant follicle-stimulating hormone (rFSH) protocol. Patients were classified into three groups: poor-responders (according to Bologna criteria), normo-responders (≤ 15 oocytes), and hyper-responders (> 15 oocytes). Genotyping of SNPs AMH rs10407022, AMHR rs3741664, FSHR rs1394205 and rs6166, and ESR1 rs2234693 was performed using high-resolution melting analysis (HRMA). Basal FSH (bFSH), estradiol (E2), and anti-Müllerian hormone (AMH) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Patients with GG genotype of FSHR rs1394205 had significantly lower AMH level (P = 0.016) and required higher rFSH dose per oocyte compared to women with AA or AG genotype (P = 0.036). We also found higher frequency of GG genotype of FSHR rs1394205 in poor- (76.5%) than in hyper-responders (37.5%, P = 0.002). Patients with AA genotype of FSHR rs6166 had higher level of measured bFSH compared to those with AG or GG genotypes (P = 0.043). Women with GG genotype of AMHR rs3741664 required higher rFSH dose in comparison with patients carrying genotypes AA or AG (P = 0.028). CONCLUSIONS The GG genotype at position rs1394205 is associated with poor ovarian response to COH. Patients with this genotype may require higher doses of rFSH for ovulation induction.
