Leuprolide decreases the amount of testosterone or oestrogen in both men and women.Leuprolide can be used to treat symptoms of prostatic cancer in men, but it does not treat cancer. Leuprolide can be used by women to treat the symptoms of endometriosis or uterine fibroids.Leuprolide can also be used to treat early puberty (early onset) in males and females older than 2 years.
