Estrone (E1) [Mass/volume] in Semen
Active
Part Description
LP15560-3 Estrone
Estrone has low biological activity compared with estridiol. In humans the major source of E1 is the extraglandular conversion of androstenedione secreted by the adrenal gland. In women the sequence of events during the menstrual cycle depends on the stimulation of the ovary by gonadotropins and feedback by the estrogens on the hypothalamus and pituitary. Under normal circumstances the amount of E1 generated is small and does not play a significant role in feedback, but under abnormal conditions [e.g. obesity] the amount may become sufficient to interfere with normal feedback mechanisms and produce disturbances of the ovarian cycle. In men, E1 levels may be helpful in the diagnosis of gynecomastia or the detection of estrogen-producing tumors.
