5 ways to enhance male fertility

Most people are aware that a women’s reproductive lifespan is limited. It’s the proverbial “biological clock.” But did you know that men have a “biological clock” as well? Check out these facts:

• Epidemiological studies have shown increased rates of autism, schizophrenia and other genetic abnormalities in the offspring of older men.
• Sperm quality deteriorates as men age.
• Men over 40 are 30 percent less likely to conceive within a year compared to men under the age of 30.
• Sperm motility and morphology (the percentage of normally-shaped sperm) have consistently been shown to decrease as men age.
• Although the studies on sperm count are more variable, the bulk of the literature would suggest that sperm concentration decreases as well.
• Increasing rates of erectile dysfunction and other medical conditions may decrease sex drive in older men.

Maintain a healthy weight 

Obesity has been shown to drop testosterone levels, which can increase the rates of erectile dysfunction and low libido. It can also drop sperm counts, and effect motility and morphology. Studies show that the sperm of obese men has difficulty with egg binding and fertilization. In short, men who are very overweight are less likely to have sex and more likely to ejaculate fewer sperm that are less effective.
 

Don’t smoke

Smoking has a negative effect on sperm, decreasing its concentration, motility and morphology. There is less research regarding marijuana and E-cigarettes (vaping), but it is reasonable to assume a similar effect, and that these should be avoided as well.
 

Don’t take testosterone

I can’t say this enough. Don’t, don’t, don’t take testosterone! Testosterone use is on the rise, and unfortunately, there are lots of providers prescribing it who are not aware of the potential side effects and risks. The production of testosterone is regulated by the amount of circulating testosterone in the blood stream. If that level is high because of testosterone use, the brain will shut down production in the testicles. Sperm production is shut down as well and can cease entirely. This is not a rare side effect. In fact, it is the norm. Stay away!
 

Get a semen analysis

Ok, so this isn’t the first thing you need to do, but if you’ve been trying for months or are considering starting medication, it is something that should be done. If there is any history of testicular/groin injury or surgery, a semen analysis should be obtained even earlier. Any physician can order a semen analysis at a local lab, or preferably, at a high-complexity lab with personnel that have additional training in semen analysis like the one at Methodist's Reproductive Health Specialists clinic.
