Biological function During the menstrual cycle, levels of estradiol (an estrogen) vary by 200 percent. Levels of progesterone vary by over 1200 percent. [38]

Sex hormone-binding globulin (SHBG) or sex steroid-binding globulin (SSBG) is a glycoprotein that binds to androgens and estrogens. When produced by the Sertoli cells in the seminiferous …

This article focuses on the nuclear estrogen receptors (ERα and ERβ). Upon activation by estrogen, intracellular ERs undergo translocation to the nucleus where they bind to specific …

Estradiol stimulates while dihydrotestosterone (DHT) inhibits breast cancer growth. Furthermore 17β-HSD1 levels positively correlate with estradiol and negatively correlate with DHT levels in …

The sharp increase in estradiol production by the dominant follicle (possibly along with a decrease in gonadotrophin surge-attenuating factor) cause a positive effect on the hypothalamus and …

Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell …
