Abstract
Summary
Daily inunction for 24 days of 270 rat units of alpha-estradiol (Progynon D-H) to normal and castrated immature male rats produced noticeable changes in the thyroid glands and in the testes of the noncastrated males. The thyroid glands appeared, histologically, in a hypoactive state. They exhibited an increased colloid content and a low follicular epithelium and destruction to the follicles. The hypoactivity appeared greater in castrated rats than in the non-castrated. Descent of the testes in immature males was prevented by the alphaestradiol.
