Is Age Just a Number…When It Comes to Sperm Health?


Men's Health

In recent news, iconic actor Robert De Niro welcomed his seventh child at the age of 79-years-old. The mother of the child is suspected to be in her forties which is considered advanced maternal age, but obviously the real shocker is De Niro! Of course, people have their opinions on whether it is fair or appropriate to father a child at his age, but what does this say about men and sperm health and vitality as they age? De Niro is certainly not the first to become a new father when the title of grandpa is perhaps more fitting.


More Famous Older Dads:

  • Richard Gere fathered a child at 69-years-old
  • Eddie Murphy, 57
  • Billy Joel, 63
  • Jeff Goldblum, first-time dad at the age of 62
  • Mick Jagger, 72
There Are 3 Basic Parameters to Consider When it Comes to Healthy Sperm.
  • Amount. According to the National Institutes of Health (NIH), daily sperm production decreases by more than 30 percent in men over the age of 50. Furthermore, it continues to decrease with age.
  • Motility. It’s an ambitious journey for sperm to reach the egg and fertilize. This is why motility is key when it comes to male fertility. Motility does decrease in older age, however, “Pregnancy is possible with less than 40% of the sperm in ejaculate moving, but 40% is considered the threshold. The more the better,” according to the Mayo Clinic.
  • Morphology (also referred to as structure). Morphology refers to the size and shape of the sperm and can be assessed when viewed under a microscope. “As reported in the WHO [World Health Organization] guidelines, the sperm head should be oval in shape, smooth, and regularly contoured, 5 to 6 µm long and 2.5 to 3.5 µm wide,” reports the NIH. Normal sperm morphology does decrease with age.

It is evident that sperm quality and quantity does decrease with advanced paternal age, and research does suggest that the risk of genetic mutations also increases, however, there are plenty of men (like the famous fathers above) that have healthy babies in older age. As always, the key is to be proactive.

Men, What's Good For Your Sperm Is Good For You!

This is a topic the pH Labs team has blogged about a lot. I highly recommend checking out these earlier blogs:


Being proactive about sperm health basically entails being proactive about overall health and wellness. If having a baby is not your desire or motivation, be inspired by happy, healthy longevity. Many consider it ‘normal’ for women to usually outlive men, but check out the story of this healthy, thriving 109-year-old man.


Enjoy your healthy life!
