Men and Miscarriage

Around a quarter of all couples will experience the heartache of miscarriage at some time.

High levels of sperm DNA fragmentation have been shown to double the likelihood of a miscarriage occurring.

While many of these will be a single sporadic event, some couples will suffer repeated – or recurrent – miscarriages. Recurrent miscarriage can be caused by several factors including abnormal chromosomes in the foetus, female hormonal problems or issues with the woman’s womb. Another significant factor in recurrent miscarriage is the quality of the man’s sperm DNA.

Sperm DNA Fragmentation

Sperm DNA is the most important part of the sperm. It contains the genetic instructions that make a baby look and act like its parents.

Sperm DNA can be damaged during sperm production and transport. This damage is known as DNA fragmentation. High levels of sperm DNA fragmentation have been shown to double the likelihood of a miscarriage occurring (Source – Men and Miscarriage Research)

Examen’s research shows that sperm from men whose partners have a history of miscarriage have higher levels of sperm DNA fragmentation than sperm from those whose partners deliver healthy babies.

We have observed high sperm DNA damage in over 85% of men whose partners had recurrent miscarriages. This was true for couples who conceived naturally as well as those who conceived with fertility treatment.

Sperm DNA fragmentation can be affected by things like stress, smoking, recreational drugs, obesity and other avoidable lifestyle factors. Men can make simple lifestyle changes to improve the quality of their sperm DNA. They can reduce their sperm oxidative stress levels by making healthier choices such as eating a better diet, taking more exercise, reducing weight, stopping smoking, reducing alcohol intake and keeping their testes cool.
