Gonadotropins are hormones that regulate sexual development, growth, and fertility. They're used to treat infertility as part of assisted reproductive technology. They also treat delayed puberty and other hormonal imbalances. Gonadotropins are typically available as injectable medications. Examples include human chorionic gonadotropin (Pregnyl, Novarel), choriogonadotropin alfa (Ovidrel), follitropin alfa (Gonal-F RFF, Gonal-F), menotropins (Menopur), and the follitropins (Follistim AQ, Gonal-F).
