Sperm concentration, motility, and morphology. The most common causes of male infertility are low sperm production, abnormal sperm function, or problems that affect sperm transport. Infertile men have oligospermia (low sperm concentrations compared with reference ranges) or azoospermia (the absence of motile sperm in semen)Illness, infection, injury, chronic medical conditions, hormonal disorders, genetic disorders, and lifestyle choices (e.g., heavy alcohol use, smoking, or illicit drug use) also may contribute to male infertility. In addition, frequent exposure to certain environmental elements such as high temperatures, toxins, medications, and radiation can adversely affect sperm production and/or sperm function.
