Can Masturbation Improve Sperm Quality and Fertility? Here's What Studies Reveal

Masturbation has always had bad pr, morally and spiritually. For years, many men grew up hearing that masturbation could “reduce strength", “waste sperm", or even harm their chances of having children. 

It’s one of those deeply rooted beliefs that have subtly shaped how male sexual health is discussed, or more often, avoided.

But a growing body of scientific studies now suggests that masturbation, when done in moderation, may actually support male reproductive health rather than harm it.

At the centre of this conversation is one key factor: sperm quality. According to the Mayo Clinic, sperm health is influenced by several factors, including movement (motility), shape, and overall count. What’s often overlooked, however, is how ejaculation frequency plays into this.

Studies have shown that frequent ejaculation may help reduce sperm DNA damage and even improve fertility, particularly in men with fertility concerns. Other things to note are:

• Sperm stored for too long may become less active

• Older sperm are more likely to develop DNA damage

• Regular ejaculation helps the body produce fresher sperm

In simple terms, the male reproductive system functions more like a continuous production cycle than a storage system.

One of the most common beliefs around male fertility is that abstaining from ejaculation leads to stronger and healthier sperm.

But according to research, if a man avoids ejaculation for a long time, his sperm count and the amount of semen increase, but the sperm don’t move as well and are more likely to carry DNA damage. 

In other words, “saving sperm” makes more sperm, but they are weaker and less healthy.

The answer is nuanced. Experts agree that:

• Moderate ejaculation frequency may support sperm health

• Extremely long periods of abstinence may not be ideal

• Balance is key.

While the study offers promising insights, professionals stress that masturbation is just one small part of overall reproductive health.

According to the Cleveland Clinic, fertility is influenced by a wide range of lifestyle factors, including:

• Diet and nutrition

• Physical activity

• Stress levels

• Substance use.

Excessive habits of any kind, whether abstinence or overindulgence, can be counterproductive.

This emerging research reframes how we think about male reproductive health. Masturbation is no longer viewed solely through a spiritual, cultural or moral lens but as a biological function with potential health implications.

And while it may remain an uncomfortable topic for some, understanding it better could help men make more informed decisions, not just about fertility, but about their overall well-being.

Because sometimes, the things we’ve been told to avoid are the very things we need to understand better.

Yes, it can help. Regular ejaculation may remove older sperm from the body and make room for newer, healthier ones.

There’s no exact number for everyone, but experts suggest that ejaculating every 2 to 5 days may help keep sperm healthy.

Yes, if it becomes excessive. It may lead to tiredness or affect daily life.
