A comprehensive diagnostic laboratory package for evaluating male infertility from a hormonal perspective. It focuses on measuring hormones of the reproductive axis: follicle-stimulating hormone (FSH), which stimulates sperm production; luteinizing hormone (LH), which stimulates testosterone production in the testes; and total testosterone. It also includes measuring DHEA-S (dehydroepiandrosterone sulfate), a key hormone precursor produced in the adrenal glands that can influence androgen levels. Additionally, it measures prolactin levels, as elevated prolactin can suppress the secretion of reproductive hormones and lead to impaired fertility.
