title: Reversible changes in the antifertility induced by Aegle marmelos in male albino rats.
abstract: To study the effects of Aegle marmelos on the testicular reproductive system, a 50% ethanolic extract of Aegle marmelos leaves (AMLEt) was fed orally to male albino rats at the dose levels of 200 and 300 mg/kg body wt./day for 60 days. Recovery was assessed for an additional 120 days. Oral administration of AMLEt did not cause body weight loss. The motility and sperm concentration were significantly reduced along with complete inhibition of fertility at a dose of 300 mg/kg. The level of serum testosterone also declined and spermatogenesis was impaired. The number of normal tubules and the height of epithelial cells of the caput and cauda were reduced significantly. The cross sectional surface area of Sertoli cells and mature Leydig cells was reduced along with a dose dependent reduction of preleptotene and pachytene spermatocytes. Thus the antifertility effects of Aegle marmelos seemed to be mediated by disturbances in structure and function in testicular somatic cells including Leydig and Sertoli cells resulting in an alteration in physio-morphological events of spermatogenesis. However, complete recovery was observed after a 120 day withdrawal.
