What lowers male fertility?

3 min read

Male fertility can be affected by a number of factors. These generally fall into several broad categories:

1. Environmental factors #

  • Chemical pollutants: Exposure to chemicals such as pesticides, herbicides, plasticizers (like phthalates) and heavy metals (lead, mercury) can affect sperm quality and quantity.
  • Radiation: Exposure to radiation, including ionizing radiation and certain types of non-ionizing radiation (such as that emitted by cell phones and other electronic devices), can impact fertility.
  • Excessive heat: Working in overheated environments, frequent use of saunas or hot baths, and even wearing tight clothing can increase scrotal temperature and impair sperm production.

2. Medical conditions #

  • Varicocele: A dilation of the veins in the scrotum that can cause the testicles to overheat and affect sperm production.
  • Infections: Certain infections, such as mumps, urinary tract infections and STIs (sexually transmitted infections) like chlamydia and gonorrhea, can affect fertility by damaging sperm or obstructing sperm passageways.
  • Hormonal disorders: Hormonal imbalances, particularly those affecting testosterone and other hormones involved in reproduction, can reduce sperm production.
  • Genetic problems: Chromosomal abnormalities, such as Klinefelter syndrome, or specific genetic mutations can cause problems with testicular development or sperm production.
  • Certain medications: Such as those for certain chemotherapies, acne treatments, steroids, and certain antibiotics taken over the long term, or certain anti-ulcer drugs.
  • Fever: Any episode of fever can have a major impact on fertility.
  • Deficiency: in zinc, selenium and vitamins C, E & A.

3. Lifestyle factors #

  • Diet: A diet low in essential nutrients can affect fertility. Excessive alcohol and caffeine consumption can also be harmful.
  • Smoking: Smoking can reduce sperm quality by lowering sperm count and motility, and by damaging sperm DNA.
  • Drugs and medications: The use of recreational drugs (such as marijuana and cocaine) and certain medications (such as those used to treat hypertension and depression) can adversely affect male fertility.
  • Stress: Chronic stress can affect the hormones needed for sperm production.
  • Occupations: Certain professions, such as bakers, cooks, lorry or cab drivers, etc., cause a momentary drop in fertility following exposure to heat. Other reductions are due to exposure to fumes or the use of toxic products.

4. Physical factors #

  • Injuries or surgery: Injuries to the testicles or surgery affecting the reproductive system can have a direct impact on sperm production and fertility.

These factors can interact in complex, often cumulative ways, underscoring the importance of a healthy lifestyle and regular medical supervision in maintaining good male fertility.
