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.
Research: This was a cohort study exploring whether the consumption of fruits and vegetables with high levels of pesticide residues is linked to lower semen quality. This type of study cannot prove cause and effect, as other factors could be causing any effects seen. However, in studies of this type, researchers try to take account of other factors that can affect a health outcome. In this case, for example, male fertility is known to be affected by lifestyle factors such as smoking and weight, which were taken into account in the statistical analyses.
The mean age of the males studied was 34 years. The semen analysis revealed the following following mean values: pH: 8, volume: 2.6 ml, concentration: 60 x 10(6)/ml, total count: 160 x 10(6), progressive motility: 42%, rapid progressive motility: 36%, viability: 47% and morphology: 8% normal forms. The consumption of alcohol, nicotine and drugs was low to moderate. Sixty-three percent of them had a normal sperm count; their germ cells had undergone the second stage of maturation and adult dark (Ad) spermatogonia were present at the time of surgery 20-25 years earlier.
