In the current study, we observed a mild increasein the prolactin level (50.65 ± 27.11 ng/ml) in68% cases, which was similar to previous studiesconducted by Kalsum and Jalali (29) where 69.51% of subfertile women suffered from hyperprolactinemia.Nizam et al. (30) also showed thathyperprolactinemia was a major cause of subfertility.Treatment with drugs that lowered prolactinlevels resulted in pregnancy for 24% of the infertilewomen. Here, PRL is linked to hyperprolactinemia.
