Gonadotropins are hormones produced by the pituitary gland that play a crucial role in regulating reproductive functions. The two main types of gonadotropins are luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones stimulate the gonads—the ovaries in females and the testes in males—to produce sex hormones and support the development of eggs and sperm. In females, gonadotropins help control the menstrual cycle and ovulation, while in males, they are essential for sperm production and testosterone secretion. Abnormal levels of gonadotropins can lead to reproductive issues, making them important indicators in fertility assessments and treatments.
