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. Having a low sperm count decreases the odds that one of your sperm will fertilize your partner's egg, resulting in pregnancy. Nonetheless, many men who have a low sperm count are still able to father a child.

Weak ejaculation: Symptoms, causes, and treatment

As male fertility is to some extent correlated with sperm count the results may reflect an overall reduction in male fertility. The biological significance of these changes is emphasised by a concomitant increase in the incidence of genitourinary abnormalities such as testicular cancer and possibly also cryptorchidism and hypospadias, suggesting a growing impact of factors with serious effects on male gonadal function.

Male infertility crisis

Subscriber Account active since. A study that analyzed sperm samples from nearly 43, men from around the world over a few decades found that sperm counts have dropped by more than half over the last 40 years. Although the definitive cause is unknown and additional research is needed to find the cause of the drastic decline in sperm counts , researchers have identified some habits and health conditions that may cause a decrease in sperm production.
A recent study that tested both men and dogs added to concerns that chemicals in the environment are damaging the quality and quantity of sperm. Make a contribution. S urprising new research into dog sperm has reproductive biologists concerned about the fate of their own species. In a March study , scientists at Nottingham University found that two chemicals common in home environments damage the quality of sperm in both men and dogs. The culprits implicated are diethylhexyl phthalate DEHP , used to make new plastics more pliable, and polychlorinated biphenyl PCB , found in older plastics and electrical equipment.
