This laboratory package is designed to assess the functional and hormonal health of the ovaries. It includes measuring follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are secreted by the pituitary gland to regulate egg growth and ovulation, and total testosterone, which is produced in small amounts in the ovaries. It also includes measuring prolactin, as elevated levels can suppress ovarian function and prevent ovulation. This package is commonly used to investigate the causes of menstrual irregularities and to diagnose polycystic ovary syndrome (PCOS).
