Pathological mechanisms to explain some cases of amenorrhoea without organic disease
Abstract:
A test is described to define the site of the lesion causing amenorrhoea in women of child-bearing age who have normal ovaries and a normal response to luteinizing hormone-releasing hormone (LH-RH). Patients able to produce a release of LH following the administration of 1 mg. of oestradiol benzoate (EB) have normal hypothalamic function and thus the site of the defect must lie more centrally in the brain. Patients unable to show these LH surges have either a primary or secondary abnormality affecting their hypothalamic oestrogen "receptor" mechanisms or their ability to produce LH-RH.

Oogenesis
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...
