Who makes estradiol?

Do you mean natural production in the body, or who makes estradiol as a medication?

- In the body: Estradiol is mainly produced by the ovaries (the granulosa cells in the follicles). During pregnancy the placenta makes large amounts. After menopause, small amounts are produced by adipose tissue via aromatase.

- As a drug: Estradiol is manufactured by many pharmaceutical companies as generic hormone therapy in various forms (pills, patches, gels, vaginal rings). There isn’t a single manufacturer. If you tell me your country and the specific form you’re interested in (oral tablet, patch, etc.), I can help identify common brands and manufacturers currently on the market.
