Abstract
- The objective of this study was to assess the role of the variant p.Asn680Ser in the FSH receptor gene (FSHR) in determining oocyte maturity. It also assessed the relationship between this FSHR variant with metaphase-II oocyte output rate (MOR) and the fertilization rate. This was a prospective observational study based at a tertiary referral centre for reproductive medicine. Women (n=212) undergoing their first cycle of ovarian stimulation for IVF with intracytoplasmic sperm injection (ICSI) were included in the study. Baseline pelvic ultrasound and blood tests were taken on day 2 or 3 of the cycle for assessment of baseline hormones and for DNA extraction. Genotypes for FSHR p.Asn680Ser was determined using TaqMan allelic discrimination assay. The outcome measures were the total dose of exogenous gonadotrophins used, antral follicle count (AFC), number of mature (metaphase-II) oocytes retrieved, MOR and fertilization rate. No statistically significant differences were found between the number of mature oocytes retrieved, MOR or fertilization rates among the patients with different p.Asn680Ser FSHR genotypes. No significant difference was noted in the clinical pregnancy rates per transfer. There is no evidence that the p.Asn680Ser FSHR genotype predicts oocyte maturity.
