Abstract
PURPOSE
To evaluate the association of single-nucleotide polymorphisms (SNPs) in the anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) genes with ovarian response and clinical pregnancy outcomes in women undergoing controlled ovarian hyperstimulation.
METHODS
In this prospective study, we genotyped AMH polymorphisms (c. -649 T > C, c. 146 T > G, c. 252 G > A, and c. 303 G > A) in 365 women and AMHR2 polymorphisms (c. -482 A > G, c. 622-6 C > T, c. 4952 G > A, c. 10 A > G) in 80 women undergoing controlled ovarian hyperstimulation for IVF.
RESULTS
Higher doses of exogenous FSH and lower numbers of preovulatory follicles were noted in women having AMH c. -649 T > C and AMH c. -146 T > G polymorphisms, respectively. Overall, we found that the presence of a polymorphic genotype (homozygous or heterozygous) at positions c. -649 T > C, c. 146 T > G, c. 252 G > A, and c. 303 G > A in the AMH gene was associated with higher doses of FSH for ovulation induction (p < 0.001). Interestingly, a higher live birth rate was noted in women with a homozygous polymorphic genotype for all four AMH SNPs investigated while none of the women showing a homozygous polymorphic genotype at all AMHR2 SNPs investigated in this study had a live birth.
CONCLUSION
Our results show that presence of AMHR2 SNPs (c. 482 A > G, c. 622-6 C > T, c. 4952 G > A, and c. 10 A > G) negatively correlate with live birth rate. However, these findings need to be validated by using larger sample size.
