Goserelin belongs to a group of medicines called antihormonal medicines. This means that it affects the levels of various hormones including testosterone and oestrogen. Goserelin works by acting on the pituitary gland in your brain to stop the production of some of the sex hormones your body makes.
It's used for many conditions including:
- Endometriosis: To reduce symptoms, including pain and the size and number of endometrial deposits.
- Uterine fibroids: Before surgery to reduce the size of the fibroids and symptoms including pain.
- Breast cancer: To reduce oestrogen production in people who have oestrogen receptor positive (ER positive) breast cancer, who are pre- or peri menopausal.
- Prostate cancer: To reduce or stop testosterone production which slows the growth of cancer or shrinks it.
- Fertility treatment: To encourage ovulation.
- Gender affirmation: As a puberty blocker, to temporarily suppress the physical changes of puberty, eg, breast development or facial hair.
