TEX11 and male infertility: In the present study, we recruited 100 patients with idiopathic male infertility (azoospermia and/or oligospermia) and 100 healthy controls from Iranian Azeri population in order to investigate correlation of CATSPER1 (rs2845570), SPATA16 (rs1515442), and TEX11 (rs143246552) genes polymorphism with idiopathic azoospermia and oligospermia risk.
