Elonva

Elonva is a hormonal medicine used in women who are undergoing fertility treatment to stimulate the development of more than one mature egg at a time in the ovaries. It is used together with a gonadotrophin-releasing hormone (GnRH) antagonist (another type of medicine used in fertility treatments). Elonva combined with another hormonal medicine called human chorionic gonadotropin (hCG) is also used to treat adolescent boys aged 14 years and older who have delayed or absent puberty due to hypogonadotropic hypogonadism. In adolescent males with this condition, production of the hormones that stimulate testicular development is inadequate. Therefore, the testes remain small and produce little or no testosterone. This results in delayed or absent pubertal characteristics, and no sperm production resulting in problems with fertility. Elonva contains the active substance corifollitropin alfa.
