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.
Of 76 boys with adult dark spermatogonia 44 (58%) had a normal mean number of spermatogonia per tubular transverse section compared to 2 of 13 (15%) without adult dark spermatogonia (p <0.05). In the 30 boys with good fertility potential, including a normal mean number of tubular germ cells, and normal gonadotropins and inhibin B, the mean number of adult dark tubular germ cells was 0.081 vs 0.031 in the 38 with low fertility potential, including impaired tubular germ cells and/or low inhibin B but no reactive increase in gonadotropins (p <0.05).
