Urine estrone

Estrone is synthesized in women mainly by ovarian granulosa cells and a small amount is derived from the conversion of androstenedione. Male estrone is mainly derived from androstenedione, and a small amount is directly secreted from the testes. The detection of estrone is important for understanding the endocrine function of the ovary and judging whether or not ovulation is effective in women of childbearing age. Women of normal reproductive age showed parallel changes in plasma estrone and estradiol throughout the menstrual cycle. After menopause, estrogen levels decreased and plasma estradiol decreased more than estrone.
