How does this medication work? What will it do for me?

Lutropin alpha belongs to the class of medications called gonadotropins. Lutropin alpha contains the human hormone luteinizing hormone (LH). Lutropin alpha is a fertility medication that helps follicles (eggs) in the ovaries to develop and mature. It is used in combination with another fertility medication called Gonal-f® (follitropin alpha) when a women's pituitary gland does not produce enough LH.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
