Male Factor Infertility Facts


Infertility’s root of the problem is typically found in either the male reproductive system or the female reproductive system since it takes one cell from each to produce an embryo and subsequently a baby. Most commonly, there’s something going on in both the male and the female that can be helped with fertility treatment.

Epididymis: Portion of the male genital tract next to the testis where sperm maturation is partially accomplished. Receives sperm from the testis and continues as the ductus (vas) deferens.

Male Factor Infertility: 30-40% of infertility is a result of problems with sperm production or motility.  Sometimes there is blockage of release of sperm.  Male factor infertility is most often treated with IUI or IVF and referral to a specially trained urologist.

Retrograde Ejaculation: A condition that occurs when, at orgasm, the ejaculate (sperm and semen) is forced backward into the bladder rather than through the urethra and out the end of the penis.

Semen: The fluid containing sperm (the male reproductive cells) that is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm).

Sperm: The male reproductive cells. With ART (assisted reproductive technology), there are methods so that very few sperm are actually needed to produce embryos.

Sperm Antibody Test: In some couples blood, semen and/or cervical mucus contain substances which hinder sperm action through an allergic or immune reaction.

Spermatogenesis: The process of producing sperm, the male reproductive cells.

Testosterone: The male hormone that is essential for sperm production and the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and sex drive.

Urologist: The type of doctor who is specially trained to treat problems of the male and female urinary system and the male sex organs.

Undescended Testicle: A condition in which the testicles do not descend from the abdomen, where they are located during development, to the scrotum shortly before birth. Also called cryptorchidism.

Vas deferens: The long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind a man’s urinary bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

Varicocele: A varicose vein around the ductus (vas) deferens and the testes. This may be a cause of low sperm counts, motility and morphology and lead to male infertility.

It’s all about the sperm AND it’s all about the male reproductive system that produces them.
