Ever wondered, “Does age really affect men’s fertility?” Dr. Sami Almusawa, medical director and fertility consultant at the Plan Your Baby telehealth clinic, addressed this in an article published by The Guardian.

His insight? “Sperm quality – including motility (movement), morphology (shape), and DNA integrity – deteriorates over time. Testosterone levels also gradually decline from around age 30, impacting sperm production.”

Research shows that as men get older, there’s an increased risk of genetic abnormalities. While men in their 40s, 50s, or beyond can still father children, conception may take longer, and risks of miscarriage or complications may rise.

At Plan Your Baby, we believe fertility should be viewed holistically — beyond myths and quick fixes. Let’s look at the most common misconceptions.

Do men remain fertile for life?

Technically, yes — but fertility potential changes. Studies confirm that sperm count, motility, and DNA quality gradually decline after 35. This can make conception more difficult and sometimes lead to higher risks of pregnancy complications.

Myths about conceiving and male fertility

  • Myth 1: Age only matters for women.
    In reality, men’s fertility also decreases with age, even if the decline is slower.
  • Myth 2: IVF always solves male fertility problems.
    While IVF is a powerful treatment, success rates depend on both partners’ reproductive health, including sperm quality.
  • Myth 3: Lifestyle doesn’t matter.
    Tight underwear, smoking, excessive alcohol, or poor diet can reduce sperm quality. Even boxers vs. briefs can play a role, though evidence suggests that overheating (e.g., hot tubs, saunas) is a bigger factor.

Can lifestyle changes help?

Yes. Regular exercise, maintaining a healthy weight, avoiding smoking and heavy drinking, and reducing stress can all improve sperm health. For some men, even switching from tight boxers to looser ones can make a difference.

Why professional assessment is essential

Every fertility journey is unique. A fertility assessment can help determine sperm health, hormone balance, and the best steps forward. In some cases, advanced treatments like IVF may be necessary — but knowing the root cause is the first step.
