Background: Gonadotropin therapy was used to stimulate the ovary in infertile women who underwent assisted reproduction treatment (ART). Numerous studies indicated that infertile women showed different responses to gonadotropin therapy. Follicle stimulating hormone receptor (FSHR) and Oestrogen receptor (ER) polymorphisms have been reported to involve induction of folliculogenesis and ovarian response to treatment.
Methods: In the present study, two polymorphisms, namely FSHR rs6165 and ESR2 rs4986938, were investigated in 198 Iranian infertile women aged less than 39 years who underwent ART. After DNA extraction, these polymorphisms were genotyped by TaqMan genotyping assay. According to the number of eggs released during ovulation, the patients were categorized into poor responders (PR) and good responders (GR). The results indicated that the good responders showed lower levels of FSH and LH than poor responders.
Results: No association was observed between ESR2 rs4986938 and poor response in Iranian women patients. Instead, FSHR rs6165 showed a strong association with ovarian response to ART (p< 0.05).
Conclusion: The obtained results indicated that FSHR rs6165, not ESR2 rs4986938, could be suggested as a candidate marker to predict poor ovarian response.

To analyze whether combinations of polymorphisms within FSHR gene influence ovarian response (OR) to stimulation. A multicenter prospective cohort study was conducted from 11/2016-06/2019 in Europe and Asia including predicted normo-responders under 38y. Patients underwent ovarian stimulation using fixed-dose 150 IU rFSH in a GnRH antagonist protocol.

Article Synopsis
- Primary ovarian insufficiency (POI) is a condition causing menstrual disturbances and ovarian dysfunction in women before age 40, with a prevalence of less than 1% that may vary based on ethnicity.
- The study investigated specific genetic polymorphisms in the follicle-stimulating hormone receptor (FSHR), estrogen receptor 1 (ESR1), and their relation to ovarian health in 139 Korean patients with POI compared to 350 controls.
- Significant associations were found between certain genotype combinations and the risk of POI, particularly involving FSHR and ESR1, which could point to genetic factors influencing the condition's prevalence and enhance understanding for potential treatments.

Around 70 percent of cases of Primary Ovarian Insufficiency (POI) etiology remain unexplained. The aim of our study is to contribute to the etiology and genetic background of POI. A total of 37 POI patients and 30 women in the reproductive period were included in this prospective, case-control study between August 2020 and December 2021.

Background: The results of studies on the association between polymorphisms in the FSHR gene and the risk of POR undergoing IVF have been inconsistent with each other, so we conducted a meta-analysis of all the available studies to explore the association between polymorphisms in the FSHR gene and the risk of POR.
Methods: Literature that met the inclusion criteria was collected by searching six electronic databases and basic data from included studies were extracted. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of association between follicle-stimulating hormone receptor (FSHR) gene polymorphism and poor ovarian response (POR) risk.

Genetic variants are predisposing factors to polycystic ovary syndrome (PCOS), a multifactorial condition that often gets triggered due to various environmental factors. The study investigates the association of the variants of genes that are involved in the steroidogenesis pathway or gonadotropin pathway with the risk of PCOS. Appropriate keywords for predetermined genes were used to search in PubMed, Google Scholar, Science Direct, and Central Cochrane Library up to January 11, 2023.
