Test Background Typically, semen consists of a mixture of secretions from several glands within the male genital tract. Only a small (~5 %) volume of the final ejaculate originates from the testis, within which spermatogenesis occurs. Male gametes (sperm) produced within the testis are necessary for a couple to conceive (achieve a pregnancy) and their presence is a determinant characteristic for the assessment of overall fertility status.
Clinical Indications Investigation of infertility or sub-fertility.
