[Influence of the maternal pineal gland on the testicular function in rats].
Female rats were exposed to a short (6L:18D) photoperiod from 21 days of age. On day 2 of gestation, animals were pinealectomized or sham-operated. Lighting regimens were not changed during the course of the study. Male offspring of the 2 groups of rats were sacrificed on days 21 after birth. Pinealectomy of the mother induced the following modifications: a decrease in prostate and seminal vesicle weights, a decrease in testicular testosterone and androstenedione content and in plasma dihydrotestosterone levels. We conclude that when rats are maintained on a 6L:18D cycle the maternal pineal gland stimulates the testicular function in 21-day-old offspring.
