Does Masturbation Cause Low Sperm Count?

Masturbation is a natural and normal aspect of human sexuality. However, there is a popular myth that frequent masturbation can lead to low sperm count or infertility. In this article, we’ll explore the potential origins of this myth, debunk it, and expand on factors that can actually hinder sperm count. 

Debunking the Myth

The myth that masturbation can lead to adverse health effects has been a part of many cultural conversations for centuries. One 18th-century pamphlet effectively titled The Heinous Sin of Self-Pollution went so far as to categorize masturbation as unnatural, filthy, and a sin. The pamphlet warns young men that if they continue their “corrupt” habit, they will end up impotent and unable to father children. 

Although our modern medical understanding of masturbation and its effects have thoroughly debunked these ideas, open discussions regarding sexuality remain taboo for many people. This reluctance to have conversations about human sexuality allows these misconceptions to remain unchallenged.

The body continuously produces sperm, and the act of ejaculation through masturbation is a normal part of this process. Ejaculation can temporarily reduce sperm count, but the amount of sperm present in a man’s semen is continuously being replenished. It takes approximately 2-7 days for new sperm cells to take the place of those expelled during ejaculation. For couples trying to conceive, avoid everyday ejaculation to ensure sperm count is at its highest. 

The Benefits of Regular Ejaculation 

Studies have shown that regular ejaculation, whether through sexual intercourse or masturbation, is actually beneficial for male reproductive health. Some health benefits include: 

• Improved Mood and Stress Relief
• Enhanced Sexual Function and Satisfaction
• Better Sleep Quality

One 2016 study found strong evidence that frequent ejaculation could even help prevent prostate cancer. 

5 Factors That Can Cause Low Sperm Count

While masturbation itself does not cause low sperm count, several other factors can influence sperm production and quality, including:

1. Poor Physical Health

Maintaining a healthy weight is helpful for optimal sperm production, as obesity can lead to hormonal imbalances that affect semen parameters. A diet lacking essential nutrients like zinc, vitamin C, and Coenzyme Q10 (CoQ10) can also contribute to poor sperm health.

2. Age

As men age, the quality of their sperm tends to decline. This decline typically starts around age 40 and becomes more significant in older age (60+).

3. Prolonged Exposure to Heat

The scrotum houses the testes and controls the temperature for optimal sperm production. It is designed to keep the testes slightly cooler than the body’s core temperature, which is why they are external sex organs. This temperature difference (assured by an exterior “housing” for the testes) is essential for producing healthy sperm. 

Prolonged exposure to high heat can damage sperm, reducing sperm motility and viability. Some examples of prolonged heat exposure include:

• Jacuzzis
• Saunas 
• Hot Baths/Showers
• And More

4. Tight Clothing

Wearing tight underwear or clothing that compresses the groin area can increase scrotal temperature. Elevated scrotal temperature is known to impair sperm production. Opting for looser-fitting underwear and clothing can help maintain a cooler environment and support healthier sperm.

5. Chemicals and Toxins

A growing body of evidence suggests that exposure to certain chemicals may affect male fertility. These chemicals can interfere with many different aspects of sperm health, including sperm count, morphology, motility, and more. According to one 2020 study, some common chemicals and other environmental culprits that can hinder male fertility include: 

• Pesticides/Herbicides (DST, DBCP, Organophosphates, Atrazine)
• Bisphenol A (BPA Plastics)
• Lead
• Natural Gas and Oil
• Radiofrequency Electromagnetic Radiation
