Low sperm count means that the fluid semen you ejaculate during an orgasm contains fewer sperm than normal. A low sperm count is also called oligospermia ol-ih-go-SPUR-me-uh. A complete absence of sperm is called azoospermia. Your sperm count is considered lower than normal if you have fewer than 15 million sperm per milliliter of semen.
Can cancer be passed on through sperm?
Researchers use sperm to deliver cancer drugs to tumors
Cancer treatment can interfere with ejaculation by damaging the nerves that control the prostate, seminal vesicles, and the opening to the bladder. It can also stop semen from being made in the prostate and seminal vesicles, or it can cut off the path that semen normally takes out of the body. Despite this, a man can still feel the sensation of pleasure that makes an orgasm. The difference is that, at the moment of orgasm, little or no semen comes out.
Men with low sperm production face increased cancer risk, study finds
Pre-pubescent boys do not have the option of sperm banking because the testicles do not contain mature sperm. Currently, there are two fertility preservation options available for pre-pubescent boys. Research shows the choices we make every day affect our chances of getting cancer.
Men who are diagnosed as azoospermic — infertile because of an absence of sperm in their ejaculate — are more prone to developing cancer than the general population, a study led by a Stanford University School of Medicine urologist has found. A diagnosis of azoospermia before age 30 carries an eight-fold cancer risk, the study says. Eisenberg is lead author of the study, published online June 20 in Fertility and Sterility. Diagnoses of male infertility and azoospermia are surprisingly common in the United States.
