Maintaining body homeostasis is a prerequisite for normal reproductive function, which is vital for the survival of the species and an important process of natural selection. Body weight is an independent regulator of the hypothalamic–pituitary–gonadal axis activity. © 2016, International Society of Gynecological Endocrinology.

Climacterium is the phase in women’s life beginning with the first menopausal symptom and cycle irregularities and ending 1 year after the last menstruation. Endocrinological, biological and clinical changes become apparent at that time. © 2016, International Society of Gynecological Endocrinology.

It is well known that hypertension can be primary or secondary. However, among secondary causes of hypertension, gender-specific hypertension is one lately recognized. © 2016, International Society of Gynecological Endocrinology.

In the ancient Rome, average life duration was 23 years; in Sweden at the end of the eighteenth century, 36.6 years for women and 33.7 for men; and in many European countries at the beginning of the twenty-first century, life expectancy was 72 and 76 years, respectively. The menopause (period in women’s life 1 year after the last menstruation until the end of life) and involutive hypoandrogenism in males (testosterone below 12 nmol/L and typical symptoms) are characterized by decrease of gonadal steroids and initiating of cardiovascular diseases (CVD). Rahman [1] found that women who entered early menopause (40–45 years) had 40% increase of heart disease. Meta-analysis confirmed these data (Table 16.1). © 2018, International Society of Gynecological Endocrinology.

Main regulators of breast metabolism are estradiol, progesterone, prolactin, growth hormone, and insulin-like growth factor 1 (IGF-1) [1]. They control cell function, proliferation, and differentiation activating intracellular signaling cascade (Erk, Akt, JNK, and Ark/Stat) of breast tissue [2]. Estrogen receptor (ER) expression in the breast is stable and differs relatively little in correlation with reproductive status, menstrual cycle phase, or exogenous hormones [3]. Estrogens have apocrine, paracrine, and intercrine effects. Receptors for estradiol are present in fibroblast, epithelial cells, adipocytes, and stromal tissue. Intramammary concentration of estradiol is 20 times higher compared to the level in the blood. Estradiol increases number of progesterone receptors, epithelial proliferation in the luteal phase, galactophore differentiation, connective tissue development, and growth hormone. © 2021, International Society of Gynecological Endocrinology.
