The Sperm Development Cycle Takes about 74 Days
Most people probably don’t give much thought to sperm development until perhaps conception appears that it’s taking longer than it should. The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility.
It is generally known that most men produce millions of new sperm every day. However, you might not know that these new sperm take about 2 ½ to 3 months to fully mature. You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract.
Keeping Sperm Healthy
Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle. Extreme temperatures, smoking, drug use, and poor diet can all impact the quality of sperm. For this reason, men looking to increase the chances of conception should consider making healthful lifestyle changes. SGF reproductive urologist and male fertility specialist, Dr. Cori Tanrikut, tells her patients that a “heart-healthy” lifestyle is a “sperm-friendly” lifestyle: eating a good diet, exercising regularly and moderately to maintain a healthy weight, avoiding tobacco and marijuana use, and consuming alcohol and caffeine in moderation are wise choices. Because of the lifecycle of sperm production, once a lifestyle change has been made—such as quitting smoking—it takes about 2 ½ to 3 months for those healthier sperm to appear in the ejaculate.
It’s also important to note that too much heat on or near the testicles can be impair sperm production. Sperm counts and quality can be adversely affected by hot baths, hot tubs, and long trips to the sauna or steam room. Also, be mindful to not rest laptops directly on the lap but instead place a pillow or book in between.
Equally important, men should consider that use of medications for treatment of “low T” (testosterone) in an attempt to address symptoms such as low energy or decreased sex drive may actually contribute to a low sperm count. Men should always be under the advisement of a physician if considering medication for treatment of low testosterone.
More about Sperm Development
When considering conception, it is also important to optimize the numbers of sperm available to reach and fertilize the egg. In this effort, it is recommended that men abstain from ejaculating for 2 to 3 days. Men who ejaculate more often have lower volumes of ejaculate and lower sperm counts in each ejaculate. This rule goes for couples who are trying to conceive on their own as well as men that are producing a semen sample for fertility treatments, such as IUI or IVF.
