Scientists have identified a new genetic mechanism that can cause severe forms of male infertility. This breakthrough in understanding the underlying cause of male infertility offers hope of better treatment options for patients in the future.

This breakthrough in understanding the underlying cause of male infertility offers hope of better treatment options for patients in the future.

The study, published today in Nature Communications, shows that new mutations, not inherited from father or mother, play a major role in this medical condition.

Experts have found that mutations occurring during the reproduction process, when the DNA of both parents is replicated, can result in infertility in men later in life.

Improving understanding

It is hoped that this new knowledge will help to provide more answers in the future about the cause and best treatment options available to infertile couples.
