[The characteristics of the progeny of rats subjected to unilateral ovariectomy].
Five-day progeny of 12 hemi-ovariectomized rats (111 ratlings) and of 9 intact females (81 ratlings) were examined. Hemi-ovariectomy was carried out 1.5-2 months before pairing with intact males. Body, testicle, ovary, adrenal, and brain mass was measured. The number of follicles in the ovaries, the section size of the tortuous seminal canaliculi in the testes, 3 beta-ol-steroid dehydrogenase activity in the adrenocorticocytes of the adrenocortical bundle zone were under study. The findings evidence a higher body mass, brain, testicular, and adrenal mass of the 5-day progeny of ovariectomized rats. Signs of advanced formation of the follicles and great numbers thereof were found in the ovaries. Another finding was a significant elevation of 3 beta-ol-steroid dehydrogenase activity in the cells of the adrenocortical bundle zone. Therefore, 5-day ratlings of the test group presented with signs of advanced physical development of the examined endocrine glands.
