The influence of sex hormones on the pineal gland of the chick: a histochemical and ultrastructural study.

AUTOR(ES)
RESUMO

The pineal gland of chicks treated with oestrogens and androgens has been studied histochemically and ultrastructurally from post-hatching until 90 days of age. The results obtained may demonstrate a precocious maturity of the gland caused by its response to the early high level of sex hormones circulating in the blood.
