What Causes A Low Sperm Count?

A man's sperm count can vary depending on many factors.

Low sperm count, also called oligospermia, significantly contributes to male infertility. In the United States, male infertility affects up to 15% of males trying to conceive. It occurs when your semen carries fewer sperm than normal. Understanding the causes can help identify the right interventions to improve fertility outcomes.

Defining Low Sperm Count

Low sperm count is a condition in which the concentration of sperm in a man’s ejaculate is lower than usual. The World Health Organization defines a “low sperm count” as fewer than 15 million sperm per milliliter of semen. The average range is between 40 million and 300 million sperm per milliliter.

This decline reduces the likelihood of a sperm successfully fertilizing an egg to result in a pregnancy. According to a study, average sperm counts decreased by 1.2% annually from 1973 to 2018, dropping from 104 to 49 million/ml. After 2000, this decline accelerated to over 2.6% per year which is again shocking.

Common Causes of Low Sperm Count

Several factors contribute to a low sperm count. Here’s a breakdown of some of the most common ones:

Medical Conditions

A variety of medical issues can interfere with sperm production or function. Here are some medical factors that can lead to a decreased sperm count:

  • Physical factors, such as a varicocele (swelling of the testicular veins), undescended testicles, or tumors
  • Hormonal imbalances
  • Infections such as STDs (e.g., Chlamydia, Gonorrhea), mumps, UTIs
  • Ejaculation issues such as retrograde ejaculation
  • Certain medications
  • Antibodies that attack sperm
Environmental Factors

The environment around you can play a big role in your reproductive health. Here are some critical environmental factors that can reduce sperm count:

  • Exposure to heavy metals or radiation
  • Exposure to industrial chemicals at the workplace
  • Overheating the testicles (e.g., frequently using saunas or hot tubs)
Health & Lifestyle

Your lifestyle choices can directly impact fertility. Below are some lifestyle factors that commonly affect sperm count:

  • Obesity and dietary choices
  • Drug and alcohol use
  • Smoking cigarettes
  • Stress, which interferes with certain hormones needed to produce sperm
Hormonal Imbalances

Hormones regulate nearly every aspect of your health, including fertility. A hormonal imbalance, including the issues mentioned below, can lead to reduced sperm production:

  • Pituitary gland issues, such as a tumor (prolactinoma) and decreased gonadotropins (FSH, LH)
  • Low testosterone levels
  • Disorders of the hypothalamus or adrenal glands
  • Use of anabolic steroids or certain supplements
  • Thyroid gland disturbances

Diagnosis and Treatment

Recognizing and diagnosing the cause of low sperm count involves comprehensive medical evaluation. It includes a physical examination, hormonal profiling, and multiple semen analyses. Depending on the underlying cause, treatments may vary and include:

Medical Treatments

These can include surgery for varicoceles, medications for hormonal imbalances, and/or treatments for ejaculation issues. There’s also intrauterine insemination (IUI) and intracytoplasmic sperm injection (ICSI) which is helpful in certain cases of infertility issues such as a low sperm count.

Lifestyle Adjustments

Lifestyle changes can significantly impact sperm count. Recommendations typically include quitting smoking, reducing alcohol intake, managing stress, losing weight, and avoiding exposure to excess heat (such as sauna or prolonged hot tub use).

In short, a low sperm count doesn’t necessarily mean you cannot father a child. It’s advisable to consult with a fertility specialist for guidance based on your specific condition. Whatever the treatment involves, each step is a move towards enhancing fertility.
