Effects of Kigelia africana (Lam.) Benth. fruits extract on the development and maturation of the reproductive system in immature male rats

In the present study, we investigated the effects of Kigelia africana (Lam.) Benth. fruits ethanolic extract in prepubertal male rats, to evaluate the influence of the extract on the reproductive system and on pubertal development. Experiments were conducted using the rodent pubertal male assay. The plant extract, analyzed by TLC, HPLC-PDA and HPLC-ESI-MS, was administered orally at doses of 200, 400 and 800 mg/kg b.w. from post-natal date 21 to post-natal day 53. Age at puberty onset, body growth, development of sexual organs exposure to plant extract or positive control were examined. Results obtained indicate that Kigelia extract, at all doses tested, significantly anticipates puberty and increases body growth and sexual organs development. These effects appears to be due to stimulation of the secretion of androgenic hormones by the compounds found in its extract and scientifically support some of its traditional uses in disorders of the male reproductive system.
