The complete absence of sperm in the ejaculate. It can result from obstruction of the vas deferens (the duct that takes the sperm from the testicles to the urethra) or from failure of the testicles to produce sperm. Obstructive Azoospermia - The result of obstruction in either the upper or lower male reproductive tract (epididymis, vas deferens, seminal vesicles or ejaculatory ducts). Sperm production may be normal (which may be verified through testicular biopsy or aspiration), but the obstruction is preventing the sperm from being ejaculated. Some causes of obstructive azoospermia are vasectomy, congenital absence of vas deferens, scarring from past infections, and hernia operations, or some genetic conditions such as Cystic Fibrosis. Some sperm may be found and extracted directly from the testicles. Non-obstructive Azoospermia: Severely impaired or non-existent sperm production in the testicle. The function of the testicle is twofold. One is production of male hormones, and the other is production of sperm. Insufficiency of one or the other is frequently congenital, but in some situations can be acquired during one’s life. If the system of the testicle which produces hormones is impaired, the hormones could be substituted by numerous preparations readily available. Unfortunately, if the system producing sperm is impaired or missing, the only substitute is donor/surrogate semen. Many couples in similar situations prefer using semen form a properly screened donor under a physician’s supervision, compared to adoption. Sometimes the genetic and biological information about the adopted child are not available; sometimes care of the child after birth has been deficient and improper, leading to the acquisition of various diseases, for example HIV/AIDS and many others.
