Our studies further confirmed reports that there were no significant associations between the FSHR Thr307Ala and Asn680Ser polymorphisms and male infertility risk.
In conclusion, the findings demonstrate that, in Brazilian population studied, genetic variations, Asn680Ser and Thr307Ala, of the FSHR gene are not correlated with serum FSH levels or sperm count in male infertility.
Evaluating the role of the FSH receptor gene Thr307-Ala and Asn680-Ser polymorphisms in male infertility and their association with semen quality and reproductive hormones.
