The gonadotropin receptors are a group of receptors that bind a group of pituitary hormones called gonadotropins. They include the:

Follicle-stimulating hormone receptor (FSHR) - binds follicle-stimulating hormone (FSH)
Luteinizing hormone receptor (LHR) - binds luteinizing hormone (LH) and human chorionic gonadotropin (hCG)
