Abstract:
A case is presented of a 23-year-old female hospitalized for infertility in whom full Morris syndrome was diagnosed. In the patient apart from testosterone level typical of a sexually mature man, high "castration" LH and FSH values and extreme hyper-estrogen secretion were found in hormonal investigation. In the histopathological pattern of the testicles removed from both inguinal canals numerous adenomas were demonstrated, originating from Sertoli cells and also, to a lesser degree, from Leydig cells. The unusual character of the case results also from complete insensitivity of the hypothalamo-hypophyseal system to circulating oestrogens and androgens (LH and FSH levels were not significantly changed after castration, and the GnRH stimulation test gave similar results before and after the operation). The authors discuss the possible mechanisms of the observed phenomena.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
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 growth — 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 release.
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...
