Biochemical and morphological changes of spermatozoa in progestin-androgen injected rats

Abstract:
Bimonthly injections (im) of medroxyprogesterone acetate (MPA, 5 mg/0.2 ml) and testosterone enanthate (TE, 2.5 mg/0.2 ml) to rats for 30 and 60 days induced oligospermia. The sperms from epididymis had defective metabolism, alterations in their morphology, viability and acrosome integrity. Thus this altered sperm function resulted in reduction in the fertility rate of MPA+TE treated animals.
