Does Frequent Sex Weaken Sperm? Myths, Facts, and Key Insights on Sperm Health

20 December 2020

Contrary to commonly held belief, having intercourse frequently does not weaken sperm or lower the quality of semen. Actually, research points to the opposite conclusion. Studies indicate that males who have ejaculated in the previous two to three days usually have the highest quality and quantity of sperm. On the other hand, extended intervals without ejaculation can actually cause the quality of sperm to decline.

In this latest article, our fertility clinic in Bangkok examines the potential effects of frequent ejaculation on sperm health and offers advice on the frequency of intercourse while attempting to get pregnant.

Does Too Much Sex Weaken Sperm?

When trying to conceive, many couples wonder if frequent sex impacts sperm quality. However, our experience has shown that while frequent ejaculation slightly reduces sperm count temporarily, it doesn’t weaken the sperm’s overall quality. The body continually produces sperm, and healthy men can ejaculate daily without significant long-term effects on fertility.

There is a maximum chance of 37% per menstrual cycle while having sex every other day. The chance of conceiving is slightly reduced to 33% if every other day and the chance of conceiving is reduced to 15% per menstrual cycle if having sex once a week.

How Often Should You Have Sex When Trying to Get Pregnant?

Time is of the essence for couples attempting to conceive. The ideal time to conceive is during ovulation, which usually occurs 12–16 days before a woman’s next period. In our experience, within this fertile window, having intercourse everyday or every other day increases the likelihood of becoming pregnant. Even while everyday ejaculation may cause a drop in sperm count, the sperm are still healthy and capable of fertilizing an egg.

Don’t put too much pressure or stress on your partner over sex, which can actually decrease your chances of getting pregnant. For some couples, it may be better to have sex every other day; even two to three days a week will do. This is partially explained by the fact that a female egg may fertilize for up to 24 hours, but healthy sperm can wait up to two or three days for an egg in the fallopian tube.

Key Points About Frequent Ejaculation and Sperm Health

• Temporary Changes: Frequent ejaculation can lead to a temporary drop in sperm count, but it doesn’t permanently affect sperm health.
• Sperm Quality: The quality, motility, and viability of sperm remain relatively stable despite regular ejaculation.
• Resting Periods: Allowing 24 to 48 hours between ejaculations can help maintain optimal sperm count, but isn’t necessary for conception.

Other Factors Affecting Sperm Health

Beyond frequency of sex, factors like diet, exercise, stress, and smoking also play crucial roles in sperm quality. A balanced lifestyle supports better sperm health, whether you’re trying to conceive or just maintaining general fertility health. Here are some potential areas to consider to optimize your sperm health:

Lifestyle:

• Smoking: Tobacco use can reduce sperm count and motility, and increase the percentage of abnormally shaped sperm. It may also damage sperm DNA.
• Excessive alcohol consumption: This can lower testosterone levels, decrease sperm production, and cause erectile dysfunction.
• Illicit drug use: Drugs like marijuana, cocaine, and anabolic steroids can impair sperm production and function.
• Obesity: Being overweight or obese can alter hormone levels, which may negatively impact sperm production and quality.
• Stress: Chronic stress can interfere with hormones needed for sperm production and may lower libido.

Medical conditions:

Sexually transmitted infections like chlamydia and gonorrhea can cause inflammation and scarring, potentially leading to reduced fertility.

Trauma:

Direct injury to the testicles can damage sperm-producing tissues and blood vessels, potentially leading to reduced sperm production or quality.

Medications:

Certain medications, including some antibiotics, antidepressants, and chemotherapy drugs, can temporarily or permanently affect sperm production or function.

Surgery:

Vasectomy: This procedure intentionally blocks sperm transport. While often reversible, success rates vary.

Abdominal or pelvic surgery: These may inadvertently damage nerves or blood vessels crucial for sexual function and sperm transport.

Age:

Advanced paternal age (typically over 40) is associated with a decline in sperm quality, including changes in morphology and motility. It may also increase the risk of genetic abnormalities in offspring.

Exercise:

While moderate exercise is beneficial for overall health and fertility, excessive high-intensity exercise can potentially reduce sperm quality. This is thought to be due to increased testicular temperature and alterations in hormone levels.
