Estradiol (17β-estradiol, E2, 1,3,5-estratriene-3, 17β-diol), a steroid hormone, is produced primarily by the ovarian follicles from testosterone. Estradiol is the most active naturally secreted estrogen. In men, estradiol originates in the testes and from extraglandular conversion of androgens.
Circulating estradiol levels are relatively high at birth in both males and females, but decrease postnatally. In prepubertal children and men, levels are non-cyclic and low. During puberty, there are gradual increases in estradiol levels in both males and females. Interactions between luteinizing hormone (LH) and follicle-stimulating hormone (FSH) cause the release of estradiol from the ovaries in premenopausal women. Estradiol secretion is low in postmenopausal women.
Research concerning estradiol has focused predominantly on reproductive issues such as conception, ovulation, infertility, and menopause. Yet, estradiol affects a diversity of biological processes involved with reproductive capacity, establishment and maintenance of pregnancy, parenting, coronary artery disease, immunocompetence, cancer susceptibility, and neuroprotection. Estradiol is also believed to affect individual differences in cognitive and socioemotional processes as well as psychopathology.
Estrogens have been measured by many immunoassay methods. Studies suggest that estradiol can be accurately measured in saliva. http://www.creative-diagnostics.com/HS-SALIVARY-17β-estradiol-EIA-KIT-234297-465.htm
