The ticking male biological clock

The ticking male biological clock

We see the female biological clock mentioned constantly when looking at fertility treatment and female infertility, but what about the males?

New research has suggested that men may also have a time limit on having children. A new study recently published in the journal Maturitas has suggested that men should consider banking their sperm before reaching “advanced paternal age”, which has been defined as between the ages of 35-45.

It has been shown that older men have a higher level of DNA fragmentation in their sperm and may experience decreased fertility, placing their female partners at a higher risk of pregnancy complications such as gestational diabetes, pre-eclampsia and long-term effects such as cognitive disorders such as autism.

The study was able to look at data from over 40 years’ worth of research and reach the conclusion that advanced paternal age may have a detrimental effect on fertility, pregnancy and the long-term health of the offspring. It has been well documented that men of advanced paternal age have a greater risk of producing offspring that have been diagnosed with schizophrenia, alarmingly one in 47 children born with fathers over 50 years of age.

It’s incredibly important to take this new research into account and for men who are looking at starting a family, to possibly start sooner or potentially freeze their sperm for later use.

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.
