Male infertility. Light micrograph of a section through the seminiferous tubules,the site of sperm production,of an infertile man. The patient has azoospermia,an absence of sperm in the ejaculate. This condition may be congenital (present from birth),due to spermatogenesis (sperm production) failure caused by exposure to toxins or because of an obstruction in the reproductive tract,caused by an infection or cancer. If there is an underlying cause this needs to be treated. Azoospermia rarely results in an absolute absence of sperm,so sufferers can father children through infertility treatment such as IVF | |
