Does age impact male fertility?

A woman is always cited as the dominant factor which affects fertility, but several studies have revealed that the age of the man also has a significant impact on the effectiveness of IVF treatment.

Recently, the Progress Educational Trust (PET) held an event solely dedicated to male fertility in Edinburgh, Scotland looking at the topic of the male biological clock. The conference covered aspects of male infertility, specifically the effect the age of the male patient has on the ability to conceive.

Previous studies have revealed that the quality and the quantity of the sperm begin to diminish with a man’s age and when an older man does succeed in conceiving a child, there’s an increased chance of DNA damage and genetic mutations. These abnormalities result in an elevated risk of a child with congenital defects, psychiatric conditions and will increase the risk of miscarriage during the pregnancy.

Some facts about male fertility and age…

  1. On an average, it takes four months to conceive if the man is 25 or less. If he is over 40, it may take up to 2 years or longer.
  2. If the male is over 45, there is a five-fold increase in the time-taken for conception.
  3. If the couple undergoes IVF treatment, the risk of not conceiving is five times higher if the male is over 41 years of age.
  4. Semen volume and sperm motility declines between 20-80 years of age.
  5. The risk of miscarriage was 27% more likely in women whose partners were over 40 years of age.
  6. And men’s age affects much more than female fertility. As a man gets older, his likelihood of having a healthy child will also decline.

Children with fathers over the age of 40 were four times as likely to develop disorders such as schizophrenia and autism.

However, the good news is that much of this is related to increased sperm DNA damage and lifestyle factors. That is why, at Fertility First, all men have their sperm DNA levels tested in our purpose build laboratory, one of only a few in the country, as part of a couple’s initial male fertility assessment. A regime of antioxidants and lifestyle changes are usually sufficient to reverse this damage, and therefore the risks, as new sperm are made.

Depending on the severity of the DNA damage the sperm might need to be retested prior to treatment to ensure back to normal DNA levels. In many cases, these male fertility treatments mean that IVF treatment is no longer necessary, and a couple can use simpler, easier treatments to get pregnant.

FAQs about improving natural fertility

Will stress affect my ability to get pregnant?

Yes, chronic stress can impact fertility by disrupting hormonal balance and ovulation patterns. Managing stress through relaxation techniques, regular exercise, adequate sleep, and mindfulness practices may help optimise your chances of conception. Consider speaking with a counsellor if stress feels overwhelming.

How does my partner's health affect our fertility?

Sperm health accounts for about 40% of conception challenges. Your partner can improve sperm health by maintaining a healthy weight, avoiding excessive heat exposure (hot tubs, saunas, tight clothing), limiting alcohol, quitting smoking, managing stress, and taking a multivitamin with antioxidants. Sperm takes about 3 months to develop, so lifestyle changes need time to show results.

When during my cycle am I most fertile?

Your fertile window typically spans 5-6 days, ending on ovulation day. For a regular 28-day cycle, this usually falls between days 10-15, with peak fertility 1-2 days before ovulation. Track your cycle using ovulation predictor kits, basal body temperature, or cervical mucus changes to identify your unique pattern. Having intercourse every 1-2 days during this window optimises your chances.
