Sperm count, or sperm concentration measures the concentration of sperm in a man’s ejaculate. Over 15 million sperm per milliliter is considered normal, according to the WHO in 2010. The average sperm count today is between 20 and 40 million per milliliter in the Western world, having decreased by 1-2% per year from a substantially higher number a decade ago. A low sperm count is also called oligospermia. You should eat foods to improve the quality of your sperm like carrots, oranges and other veggies.
The numbers of sperm per ml of semen fell at about two percent a year between 1989 and 2005, with researchers calculating the average 35-year-old man would see his sperm count reduced from around 73.6 million per ml of semen to 49.9 million, the journal Human Reproduction reports. Diabetes increases the risk of DNA damage in sperms, resulting in infertility. Studies have also found that in diabetics the sperm’s motility was 22% as against 46% in healthy individuals. Also, the sperm count diabetic men was less than half of that of the healthy group. 92% of the diabetic men had abnormal sperm structure as opposed to 11% of the normal group.
The use of these steroids among teenagers may result in the shrinking of testes, decrease in the sperm count, which in turn leads to infertility. A varicocele is a swelling of the veins that drain the testicle. This may prevent normal cooling of the testicle, leading to reduced sperm count and fewer moving sperm. Overheating the testicles, health, lifestyle and obesity, tight underwear are other reasons that cause a low sperm count.
