Objective To evaluate the association of GGN repeat polymorphism of androgen receptor(AR)with ovarian reserve and ovarian response in controlled ovarian stimulation(COS).Methods This genetic association study was conducted among a total of 361 women aged≤40 years with basal FSH≤12 U/L undergoing the GnRH-agonist long protocol for COS in a university affiliated IVF *** repeat in the AR gene was analyzed with Sanger *** primary endpoint was the number of antral follicle counts(AFCs),and the secondary endpoints were stimulation days,total dose of gonadotropin(Gn)used,total number of retrieved oocytes,ovarian sensitivity index,and follicular output *** The GGN repeat in exon 1 of the AR gene ranged from 13 to 24,and the median repeat length was *** on the genotypes(S for GGN repeats0.05).Generalized regression analysis indicated no significant differences in ovarian stimulation parameters among the 3 groups,either before or after adjusting for confounding factors(P>0.05).Conclusion GGN repeat length on the AR gene is associated with AFC but not with ovarian response in Chinese women,indicating that AR gene polymorphisms may affect ovarian reserve.
