Abstract: This study is aimed at determining the effect of Nicotine on male fertility by evaluating some andrological parameters of male Wistar rat such as sperm parameters (spermatozoa count and motility), serum concentration of testosterone and testicular weight. Histopathology of the testis was also carried out on the effect of nicotine on testicular microstructure. 20 adult male rats were randomly divided into four groups, the test groups were administered with 0.2mg/100g, 0.4/100g and 0.6/100g body weight daily for 30 days while the control were administered with 2mls 0.9% physiological saline. Nicotine caused a significant reduction (P < 0.05) and (P< 0.01) in the mean values of sperm count, serum testosterone concentration and testicular weight in the test when compared with the control. Also, in the test group, the deleterious effect of nicotine on the sperm parameters and testosterone concentration was corroborated by histopathology which revealed a marked degeneration of germ cell layers in the seminiferous tubule and disruption of interstitial cells of the testis thereby interfering with spermatogenesis and testosterone secretion while there was no visible change in the control group. It was concluded that nicotine exerted toxic effect on the germ cell layers in seminiferous tubule with concomitant reduction in reproductive potentials of the male rat whilst showing no significant change in sperm motility. Nicotine and nicotine based products should therefore be taken with caution in cases of infertility.
