Estradiol enantate (E2-EN or EEn), also spelled estradiol enanthate and sold under the brand names Perlutal and Topasel among others, is an estrogen medication which is used in hormonal birth control for women
Estradiol has several functions in the female body. Its main function is to mature and then maintain the reproductive system. During the menstrual cycle, increased estradiol levels cause the maturation and release of the egg, as well as the thickening of the uterus lining to allow a fertilized egg to implant.
Estriol (E3) and estradiol (E2) are two different forms of the female hormone known as estrogen (sometimes referred to as oestrogen). These forms of estrogen are steroid hormones that are naturally found in the body. Estriol and estradiol can be used as hormone replacement therapy (HRT) for women after menopause.
