The FSH and LH panel is a comprehensive reproductive hormone test that measures both follicle-stimulating hormone and luteinizing hormone to evaluate the hypothalamic-pituitary-gonadal axis. This panel provides a complete assessment of reproductive function in both men and women. FSH stimulates ovarian follicle development in women and sperm production in men, while LH triggers ovulation in women and testosterone production in men. The ratio of FSH to LH is particularly important for diagnosing reproductive disorders. Elevated levels of both hormones often indicate primary gonadal failure, while low levels suggest pituitary or hypothalamic dysfunction. This panel is essential for evaluating infertility, menstrual irregularities, delayed or precocious puberty, and pituitary function. It helps distinguish between different causes of reproductive dysfunction and guides appropriate treatment decisions.
