Active male gerbils were administered lut-ovocyclin (Progesterone=20mg and estradiol dipropionate=2mg, in one ml of oil solution) intramuscularly. Histological and enzyme histochemical studies were made after 11 days at two dose levels i. e. 2 mg and 4mg respectively. The histochemical observations revealed marked inhibition of alkaline and acid phosphatases, non-specific esterase and succinic dehydrogenase activities. The lipid content increased in the Sertoli cells. The inhibitory changes thus produced might be taken as an indication of decreased release of gonadotrophins from the pituitary.
