Furthermore, maternal age correlated positively with serum FSH level (r=0.229, p<0.001;***), with the duration of infertility (r= 0.143, p<0.001;***), and negatively with AMH level (r= - 0.249, p<0.001;***), and with the number of follicles (r= -0.263; p<0.001;***). This evidence concerns the gene BRD2 and Infertility.
