Objective To assess whether an FSH receptor polymorphism (Asn680Ser, rs6166) can affect the outcome of ovulation induction in normogonadotropic (World Health Organization class 2 [WHO2]) anovulatory subfertile women. Design Prospective, longitudinal, cohort study. Setting University-based fertility unit. Patient(s) A total of 240 consecutive women diagnosed with WHO2 anovulatory subfertility who underwent ovulation induction therapy. Results were replicated in a retrospective cohort of 185 patients with polycystic ovary syndrome (PCOS) (Rotterdam criteria). Intervention(s) Ovulation induction using clomiphene citrate (CC) as first-line and exogenous gonadotropins (exFSH) as second-line therapy. Main Outcome Measure(s) Clomiphene-resistant anovulation (CRA), clomiphene failure (CCF), and ongoing pregnancy rate. Result(s) Genotyped patients (n = 159) were similar to nongenotyped women (n = 81) regarding clinical characteristics and outcomes of ovulation induction. The 680Ser allele was associated with CRA. A pooled analysis of both cohorts showed an 89% higher chance of CRA after CC treatment (odds ratio 1.9 [95% confidence interval 1.1–3.3]) in homozygous carriers of the FSH receptor variant (680Ser/Ser). A lower chance of ongoing pregnancy (hazard ratio 0.51 [95% confidence interval 0.27–0.98]) was observed among these patients during CC treatment in the prospective cohort. Conclusion(s) An FSH receptor polymorphism is associated with CRA during treatment with clomiphene citrate. These data may be used to design a treatment algorithm that is more efficacious and better tailored to the individual patient.
