Gonadotropins are peptide hormones that play a central role in regulating reproductive function in both females and males. They control ovarian and testicular activity and are essential for normal growth, sexual development, and fertility. In humans, the main gonadotropins include follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are produced by the pituitary gland, as well as human chorionic gonadotropin (hCG), which is produced by the placenta during pregnancy.

Prolactin (PRL) is a hormone produced by the pituitary gland. Normal range: less than 20 ng/mL in men, less than 25 ng/mL in non-pregnant women. Elevated prolactin (hyperprolactinemia) can cause infertility, irregular periods, and galactorrhoea. The
