Hormonal control of odors in urine and secretions

Numerous studies have shown that reproductive hormones regulate skin gland activity. [Pg.52]

Testosterone stimulates secretion in sebaceous and apocrine glands in rabbits, rats, guinea pigs, and hamsters, while estrogen in most cases inhibits secretion. Progesterone tends to be neutral (reviewed by Ebling, 1977). [Pg.52]

As expected, castration affects gland size, activity, and composition of the secretion profoundly. Eor example, castration changes the levels of porphyrins, indoles, and proteins in the Harderian gland secretion of the Syrian hamster (Buzzelletflk, 1991). [Pg.52]

The secretion of the sebaceous glands on the haunch of male and estrous and diestrous female rats varies considerably between individuals. No one single compound is characteristic of sex or reproductive condition. Gas liquid [Pg.52]
