Many couples today face challenges when trying to start a family, and male infertility plays a significant role in about half of those cases. Experts note that roughly one in ten couples deals with infertility after a year of regular attempts without success. Factors like postponing parenthood, higher rates of obesity, environmental pollutants, and various health issues contribute to this growing concern. While discussions often focus on women’s fertility, male factors deserve equal attention since effective solutions exist for many situations.
One major contributor to male infertility involves issues with sperm production or quality. Problems can include low sperm count, poor motility where sperm struggle to swim effectively, or abnormal shapes that hinder fertilization. Unlike women who experience a sharp decline in fertility after age 35, men’s fertility decreases more gradually with age. Older age leads to reduced semen volume, weaker ejaculation, lower sperm movement, and greater DNA damage in sperm cells, all of which can make conception harder.
A common and treatable cause stands out as varicocele, which involves enlarged veins in the scrotum much like varicose veins elsewhere in the body. This condition affects about one in five men overall and appears in two out of five men dealing with infertility. Varicocele often develops during adolescence and impairs sperm production and motility by raising testicular temperature or disrupting blood flow. Men should mention any scrotal swelling or discomfort to their doctor promptly for evaluation.
Diagnosis usually starts with a semen analysis, commonly called a spermogram, which checks sperm count, movement, and morphology. Doctors recommend this test early, even before active trying begins, to catch potential problems sooner. A referral might come from a primary care physician, urologist, or fertility specialist. The analysis also includes hormone checks like testosterone and follicle-stimulating hormone levels to assess testicular function. Normal ranges include at least 15 million sperm per milliliter of semen, with 40 percent or more showing good motility and at least 4 percent normally formed.
Lifestyle changes often make a big difference in improving male fertility. Excess weight disrupts hormone balance by converting testosterone into estrogen in fat tissue, so maintaining a healthy diet and exercising regularly helps restore balance. Aim for cardio sessions at least three times weekly plus strength training twice a week. Avoiding excessive heat around the testicles, such as from prolonged saunas, hot tubs, or laptops on the lap, protects sperm production since it thrives at slightly cooler temperatures. Reducing exposure to toxins like certain plastics and chemicals also supports better outcomes.
Medications can address specific issues, such as stimulating natural testosterone production or blocking its conversion to estrogen, which may boost sperm counts. Supplements rarely provide strong benefits if nutrition is already solid. When simpler approaches fall short, surgical options become viable. Procedures can repair varicoceles, clear blockages in ducts, or retrieve sperm directly from the testes for use in assisted reproduction like in vitro fertilization.
Dr. Bobby Najari, who directs the Male Infertility Program at NYU Langone Health, emphasizes that many cases respond well to these interventions. Open conversations with partners ease emotional stress, reminding everyone that infertility affects both genders equally and remains a common experience.
