Abstract:
It took many years since the initial publication of data from the Women's Health Initiative (WHI) study until further analyses and additional accumulated clinical information allowed realization of the full scope of its results. At first, the focus was on morbidity, mainly the slightly higher incidence of cardiovascular events and breast cancer cases among postmenopausal hormone users. Then, the age factor became evident, and the good safety profile of hormone therapy in healthy women initiating treatment near menopause and using it for up to 10 years eased the previous concerns. Now, 15 years after the first release of the WHI data, long-term follow-up of the WHI cohort enables consideration of mortality records as well. These data were recently summarized by the WHI investigators as follows: 'Among postmenopausal women, hormone therapy with CEE plus MPA for a median of 5.6 years or with CEE alone for a median of 7.2 years was not associated with risk of all-cause, cardiovascular, or cancer mortality during a cumulative follow-up of 18 years.' It seems that the bitter debate on the hazards of postmenopausal hormone therapy has come to an end, since the existing database permits clear and rationalized prescribing decisions.

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...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
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...
