Hormone-producing tumors of the ovary

Abstract:
The ovary is an endocrine organ that gives rise to a wide variety of neoplastic and tumorlike nonneoplastic conditions, some of which are associated with endocrine activity. The hormones produced may be steroidal or nonsteroidal. The ovary is unique among endocrine organs in reacting to the presence of nonendocrine tumors within it by abnormal or inappropriate production of sex steroidal hormones. A classification of hormone-producing ovarian lesions is proposed based on the World Health Organization's histologicai typing of ovarian tumors.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
Major Hormones and Their Functions
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...
