Abstract:
During recent years, new advances in the field of estrogen signaling (e.g., the discovery of the second estrogen receptor named ERβ) have led to the conclusion that all the major human tissues are estrogen-responsive. The impact of estrogen on human health is far more complex and stronger than scientists had previously thought. Several scientists suggested that the interplay between ERα and ERβ (antagonism, synergism, etc.) simulates a Yin-Yang relationship. This article is intended to integrate the Yin-Yang theory of Traditional Chinese Medicine with modern scientific findings on estrogen signaling to offer a better understanding of the complex interactions between ERα and ERβ. A different approach, such as that of Yin-Yang theory, may complete the standard scientific perspective, reveal hidden meanings of the tissue-dependent ERα-ERβ predominance, and reveal new aspects of estrogen-receptor imbalance.

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...
