Recurrent miscarriage and DNA fragmentation

Recurrent miscarriage and DNA fragmentation

Experiencing a miscarriage can be both emotionally and physically debilitating. Experiencing recurrent miscarriages can not only add to the already traumatic situation, but it can also leave patients feeling frustrated and searching for answers.

There have been previous studies that have identified a link between DNA damage in a man’s sperm and recurrent miscarriage, and the most recent study coming out of the UK at the Imperial College London adds to it.

So, is there a link between miscarriage and DNA fragmentation?

The researchers analysed the sperm quality of over 50 men whose partners had suffered from recurrent miscarriages and compared the results with men whose partners had not experienced miscarriages. The sperm from the recurrent miscarriage group was found to have significantly higher levels of DNA damage compared to the other group- in fact almost twice the amount!

It has been thought that the DNA damage in sperm may be caused by reactive oxygen species (ROS) that are created by semen cells to protect the sperm from infections and bacteria, however high concentrations they have been shown to have a negative effect in sperm cell DNA. When the researchers looked at levels of ROS in the semen samples from the recurrent miscarriage group, it was found that the levels had a four-fold increase compared to that of the other group of men.

Fertility First has recognised the importance of sperm health when it comes to fertility and healthy pregnancies and has been testing for sperm DNA damage in patients for over 13 years.

Our clinic will perform routine testing on all our male patients, including potential donors before fertility treatment commences to give you the best chance of being able to achieve a healthy pregnancy.

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.
