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.
Total sperm count, semen volume and testosterone showed significant dose-dependent decreases upon treatment with 10%-60% CaCl2 compared with either the control group (0% CaCl2) or baseline for each treatment group. Azoospermia was achieved for at least 12 months PI in 60% and 80% of treated dogs after administration of a 10% and 20% CaCl2, respectively. Treatment with 30% or 60% CaCl2 resulted in azoospermia in 100% of dogs, but more side effects were observed, while no side effects were noticed at lower doses.
