Estradiol is a naturally occurring and bioidentical estrogen, or an agonist of the estrogen receptor, the biological target of estrogens like endogenous estradiol. [10] Due to its estrogenic activity, estradiol has antigonadotropic effects and can inhibit fertility and suppress sex hormone production in both women and men.
Estrogens may be used in treatment of infertility in women when there is a need to develop sperm-friendly cervical mucus or an appropriate uterine lining. [65] [66] It is also commonly used during in vitro fertilization (IVF). Estrogen helps maintain the endometrial lining of the uterus and help prepare for pregnancy.

[22] [21] [40] Treatment with the antiestrogenic selective estrogen receptor modulator (SERM) tamoxifen has been found to decrease sexual desire in men treated with it for male breast cancer. [41] However, other studies have not found or reported decreased sexual function in men treated with SERMs including tamoxifen, clomifene, raloxifene, and ...
Natural pregnancy before the age of 20 has been associated with a 50% lifetime reduction in the risk of breast cancer. [56] Pseudopregnancy has been found to produce decreases in risk of mammary gland tumors in rodents similar to those of natural pregnancy, implicating high levels of estrogen and progesterone in this effect.
An estrogen (E) is a type of medication which is used most commonly in hormonal birth control and menopausal hormone therapy, and as part of feminizing hormone therapy for transgender women. [1] They can also be used in the treatment of hormone-sensitive cancers like breast cancer and prostate cancer and for various other
Estrogen can also reduce vaginal atrophy and increase sexual arousal, frequency and orgasm. [22] The effectiveness of hormone replacement can decline in some women after long-term use. [22] A number of studies have also found that the combined effects of estrogen/androgen replacement therapy can increase libido and arousal over estrogen alone. [22]
Estrogen is the predominant sex hormone that slows bone loss (even in men). Both estrogen and testosterone help stimulate bone formation (T, especially at puberty). Testosterone may cause an increase in cortical bone thickness in transgender men (however this does not necessarily translate to a greater mechanical stability).
