At What Age Does a Man Stop Making Sperm?
Unlike women, who experience menopause and a clear end to fertility, men can produce sperm well into their later years. But does that mean sperm production stays the same forever? Not quite.
The truth is that men don’t completely stop making sperm at any specific age. Sperm production continues through most of a man’s life—sometimes even into his 80s. However, the quality, quantity, and mobility of sperm decline with age, affecting fertility potential.
How Sperm Production Works
Sperm is produced in the testicles through a process called spermatogenesis. It’s a 64-day cycle regulated by hormones such as testosterone, FSH, and LH. As long as these hormones are present in sufficient levels and the testicles are functioning properly, sperm production continues.
This means that even aging men with decreased libido or erectile function may still produce viable sperm, though with reduced fertility.
Sperm Decline Over Time: What to Expect
Here’s a breakdown of how sperm typically changes with age:
- Age 20–35: Peak sperm production and mobility.
- Age 35–50: Gradual decline in sperm count, volume, and motility.
- After 50: Higher rates of DNA fragmentation, reduced testosterone, and slower regeneration.
While sperm doesn’t stop being produced, the chances of successful conception can decline due to poorer quality.
Can You Father a Child at 70?
Yes—there are numerous documented cases of men fathering children in their 60s, 70s, and even 80s. Famous examples include celebrities and politicians. However, advanced paternal age has been linked to higher risks of genetic mutations, autism spectrum disorders, and schizophrenia in offspring.
So while sperm production continues, the genetic integrity of that sperm becomes increasingly compromised with age.
Factors That Impact Sperm Production with Age
- Testosterone Decline: Reduces stimulation for sperm creation.
- Oxidative Stress: Damages DNA in sperm cells.
- Environmental Toxins: Long-term exposure to plastics, pesticides, and radiation can impair sperm health.
- Lifestyle Habits: Smoking, alcohol, obesity, and lack of exercise accelerate sperm degradation.
Signs That Sperm Quality May Be Declining
Men may notice:
- Lower semen volume
- Watery or discolored ejaculate
- Longer time to conceive with a partner
- Reduced libido or energy (often tied to testosterone)
If you’re over 40 and planning to have kids, it’s worth getting a semen analysis to check your fertility status.
Can You Boost Sperm Quality After 40?
Absolutely. Even though aging is inevitable, sperm health is highly responsive to lifestyle interventions:
- Exercise and weight control
- Supplements like zinc, CoQ10, L-carnitine, and folate
- Stress reduction and better sleep
- Limiting alcohol and quitting tobacco

Common Myths About Male Fertility and Age
- Myth: Men stop producing sperm at 50.
Truth: Sperm production continues, though quality may drop. - Myth: Low libido means no sperm.
Truth: A man can still produce sperm even with reduced sex drive. - Myth: Aging only affects women’s fertility.
Truth: Male fertility is also age-sensitive, just less dramatic.
When to Get Checked
If you’re over 40 and planning to conceive, talk to a fertility specialist. A semen analysis can reveal key metrics like sperm count, motility, morphology, and DNA fragmentation index (DFI). These indicators provide a snapshot of your fertility health.
Final Thoughts
So, at what age does a man stop making sperm? Technically, never—sperm production continues for life. But age does reduce quality, potency, and fertility potential. The earlier you take action to preserve your sperm health, the better your outcomes will be.

Sperm Morphology and Aging
One of the most overlooked aspects of sperm health is morphology—the size and shape of the sperm. As men age, morphology often declines, with a higher percentage of misshapen or immotile sperm. These abnormalities can reduce the chances of successful fertilization and may contribute to miscarriage or developmental issues.
A 2017 study found that sperm morphology and DNA fragmentation both worsen significantly after age 45. This highlights the importance of lifestyle and antioxidant intake as protective factors.
How Aging Affects Sperm DNA
Even though sperm are continually produced, aging testicular cells accumulate DNA damage over time. This means that while sperm count may remain sufficient, the genetic integrity may be compromised. This is why fertility clinics often perform DNA Fragmentation Index (DFI) tests on men over 40 who are trying to conceive.
Men with high DFI can still father children, but the risks increase. Taking CoQ10, vitamin C, and lifestyle interventions can help reduce DNA damage.
Benefits of Younger Sperm vs. Older Sperm
Younger sperm tend to be:
- More mobile
- Higher in volume and concentration
- Lower in DNA mutations
- Less oxidative stress
However, older sperm can still fertilize eggs. The key is improving cellular health and reducing exposure to harmful substances like BPA, pesticides, and trans fats.
How to Keep Sperm Young
Here are evidence-based ways to preserve or improve sperm function:
- Exercise regularly (especially resistance training)
- Eat antioxidant-rich foods like berries, dark chocolate, and leafy greens
- Use supplements like ashwagandha, zinc, and folate
- Limit exposure to plastics, heat (like saunas or laptops), and chronic stress

Do You Still Produce Sperm After a Vasectomy?
Yes. A vasectomy only blocks the sperm-carrying tubes (vas deferens), preventing sperm from mixing into the ejaculate. But the testicles still produce sperm, which are reabsorbed by the body. So while you won’t release sperm, your body continues making them indefinitely.
The Psychological Side of Aging and Fertility
Even if sperm production continues, many men struggle with the psychological pressure of declining fertility. Feelings of inadequacy, failure to conceive, or comparing oneself to younger men can damage confidence. That’s why sexual identity should be built on communication, experience, and presence—not just reproduction.
Final Take: Optimize What You’ve Got
There’s no magic age when men stop making sperm. The decline is real, but it’s gradual and manageable. With the right information, lifestyle, and mindset, you can stay fertile longer and keep your sexual vitality strong.
