Table of Contents

If a man has fewer than 15 million sperm per millilitre of semen, then it can be said that he has a low sperm count. This condition is known as oligozoospermia. Low sperm count is very a common condition and is associated with infertility i.e. the inability to become a father.

Unlike other health conditions, low sperm count has very few signs and symptoms. Everything happens internally and by the time a man comes to grips with the fact that he has a low sperm count, the damage is already done. Various factors contribute to low sperm count. The first step towards tackling the problem of low sperm count is to understand the causes and try and minimize them in order to prevent any future problems.

Listed below are the causes of low sperm count:

Underlying health conditions: Health conditions like Varicocele, Retrograde ejaculation, diabetes, spinal injuries, etc are associated with low sperm count. The best way to increase sperm count is to treat the underlying health condition with the help of an expert.

Obesity: Obesity is one of the risk factors for low sperm count. According to a study by Jorge Chavarro, assistant professor of nutrition and epidemiology at Harvard School of Public Health (HSPH), “overweight men were 11 percent more likely to have a low sperm count and 39 percent more likely to have no sperm in their ejaculation.”

Genetic disorders: Some men are vulnerable to low sperm count due to their genes. Genetic disorders like Kartagener's syndrome, cystic fibrosis, Kallmann's syndrome contribute to low sperm count in men.

Overheating of the testicles: According to various studies, overheating of the testicles due to tight clothing, sitting for long hours in the position, steam baths, etc is responsible for low sperm count temporarily.

Consumption of alcohol, tobacco and other drugs: According to multiple studies, the consumption of alcohol lowers testosterone levels in the body due to which the sperm production process is heavily affected. In addition to that, it has been found that smokers have low sperm count in comparison to non-smokers,

Environmental factors: Exposure to dangerous environmental elements like x-ray radiations, industrial chemicals like xylene, pesticides and other organic solvents have a negative impact on sperm count.
