The aim of this study was to investigate the effects of Sertraline on gonad-pituitary cycle (Testosterone, FSH and LH) and reproductive cells in adult male Balb/C mice. Adult male Balb/C mice were divided into the following 5 groups: control group with no treatment, sham group which received solvent, and the experimental groups which received one dose of Sertraline (0.0178 mg/kg) in the first group, two doses of Sertraline (0.0356 mg/kg) in the second group, and three doses of Sertraline (0.0534 mg/kg) in the third group. Mice were anaesthetized after 7 weeks. Serum samples were collected and Testosterone, FSH and LH levels of serum were assayed. Vase deferans were analyzed for motility, number and viability of sperms. The results of this study showed that the viability, count and motility of sperms were decreased. Testosterone level of blood was also decreased while FSH was increased. There was no significant change in LH level. It is suggested that Sertraline at higher dose decreases sperm production and has the potential to affect adversely fertility in male mice.
