title: Effect of medroxy progesterone acetate and testosterone enanthate on vas deferens of rats.
abstract: Effects of medroxy progesterone acetate (MPA; 5 mg/kg) and MPA + testosterone enanthate (TE) (3 mg + 2 mg/kg) were investigated in vas deferens and on fertility (along with reversibility study) for 60 days through histopathology, morphometric and certain biochemical parameters such as total proteins, sialic acid, ATPase, SDH and testosterone. The study revealed for altered histopathology and contratile pattern of vas deferens resulting in reduced fertility. The study also indicated androgen antagonistic effect. These effects were found to be reversible 4 and 3 months after withdrawal of MPA and MPA + TE injections respectively. Thus, both types generated functional sterility in the rat, but MPA affected histophysiology of vasal tissue.
