When discussing fertility, attention often turns first to women. However, male fertility is directly or indirectly responsible for up to 50% of cases involving difficulties conceiving. And yet, many men do not consider caring for their reproductive health—until a problem arises.
This article is not meant to alarm you, but rather to encourage thoughtful reflection from a compassionate place: your body, your health, and your potential to become a father—if that is your desire—deserve attention. Often, safeguarding fertility starts with something as simple (and complex) as self-care.
What Do We Mean by Male Fertility?
Male fertility refers to the ability to produce healthy, motile sperm in sufficient quantity and with intact DNA, capable of fertilizing an egg and resulting in a viable pregnancy.
Although it may seem like an automatic process, sperm production depends on numerous factors. Some are genetic or medical and beyond our control, but many are directly linked to daily habits.
Why Talk About Male Self-Care?
Because the male body speaks, too. And often, we ignore it until warning signs appear: fatigue, insomnia, loss of libido, hormonal imbalances, or trouble conceiving.
Self-care is neither a trend nor a selfish act—it is preventive health. It is emotional responsibility. And in the context of fertility, it is a powerful tool to improve your chances of starting a family.
Key Factors Affecting Male Fertility (And What You Can Do)
Nutrition: Eat to Support Your Fertility
A diet rich in fruits, vegetables, legumes, nuts, olive oil, fatty fish, and whole grains provides antioxidants, zinc, selenium, and vitamins E and C, which help protect sperm from oxidative damage.
Studies have shown that a Mediterranean-style diet improves semen quality (Salas-Huetos et al., 2017). Limit intake of saturated fats, refined sugars, and ultra-processed foods, as they harm not only your overall health but also your fertility.
Body Weight: Balance Matters
Both overweight and extreme underweight can alter hormone levels and reduce sperm quality. Maintaining a healthy weight supports a more stable hormonal environment for spermatogenesis.
Physical Activity: Moving Is Caring
Regular exercise improves circulation, reduces stress, regulates hormones, and boosts testosterone production. However, excessive training can have the opposite effect.
Overtraining or using anabolic steroids (common in bodybuilding environments) can significantly reduce natural sperm production (Vaamonde et al., 2009).
Rest and Mental Health: Also Part of Fertility
Poor sleep and chronic stress directly impact testosterone levels. Stress also raises cortisol, a hormone that can suppress reproductive functions.
Practicing relaxation techniques, meditating, disconnecting from screens in the evening, or seeking psychological support if needed is also a vital aspect of fertile self-care.
Avoid Tobacco, Alcohol, and Drugs
-
Tobacco: Lowers sperm count and motility, and increases DNA damage.
-
Alcohol: In excess, reduces testosterone production and impairs spermatogenesis.
-
Recreational drugs (e.g., marijuana, cocaine): Impair sperm quality and sexual function.
The good news? If you quit these habits, your body can regenerate. Sperm production renews approximately every 72 days.
Testicular Heat: A Small but Significant Factor
Testicles require a slightly lower temperature than the rest of the body to function optimally. Frequent use of saunas, hot baths, tight underwear, or placing a laptop on your lap for extended periods can impair sperm production. No need for obsession—just awareness.
Environmental Pollutants and Toxic Substances
Many men live or work in environments exposed to chemicals, heavy metals, or endocrine disruptors found in plastics, pesticides, or cosmetics.
While total avoidance may be impossible, you can reduce exposure by choosing BPA-free products, using protection when handling chemicals, and ventilating your home and workspace.
Does Age Matter in Male Fertility?
Yes—despite common misconceptions. As men age, sperm quality decreases. After age 40, levels of sperm DNA fragmentation rise, which can affect fertilization, embryo development, and the future child’s health (Johnson et al., 2015).
Becoming a father at 40 or 50 is possible, but it is advisable to do so with medical guidance and a healthy lifestyle.
When Should You Seek Help?
If you’ve been trying to conceive for over 12 months (or 6 months if your partner is over 35), both partners should undergo fertility testing. For men, the first step is a semen analysis, which evaluates sperm count, shape, and motility.
Additional tests may include sperm DNA fragmentation or hormonal assessments if production issues are suspected.
Fertility Is Not Synonymous with Virility
One of the greatest myths is equating fertility issues with being “less of a man.” Nothing could be further from the truth. Fertility is a biological function—not a measure of masculinity or sexual desire.
Discussing male fertility is talking about health, future, and connection. Seeking medical or psychological help is not a weakness, but an act of courage.
In Summary: Care for Your Body, Care for Your Fertility
Male fertility is not an unfathomable mystery. In many cases, improving it depends on everyday decisions—what you eat, how you sleep, how you manage stress, whether you exercise or smoke.
You don’t have to do everything perfectly. The first step is being informed. The second is making small, sustainable changes. And the third is consulting a professional if something feels off.
Fertility is not something you simply “have or don’t have.” It is something you nurture. It is something you care for.
