Infertility in males is characterized by inability to either produce sperm or to produce viable sperm or mobile sperm resulting in prohibiting fertilization of the female ovum (egg).
To the left is a false-colour scanning electron micrograph of seminiferous tubules in the human testis (cross section), the site of production and maturation of sperm.
Round undifferentiated cells lining the tubule wall (brown, pink) become sperm by halving their chromosome number, and transforming in a process which takes about two months. During this time the cells move toward the centre of the tubule and develop tails (orange). Mature sperm migrate up the cavity of the tubule and are stored in the epididymis. 200-300 million sperm are released in an average ejaculation. Courtesy of Professor P.

Male androgen hormones control the development and maintenance of male sex organs and masculine secondary sex characteristics and are required for health, especially bone health.
Testosterone is the major andogen hormone. While most of this steroid is produced by the testes, some is also produced by the adrenal glands.
