Miscarriage is an incredibly painful experience, and while it’s often assumed that the physical and emotional toll falls solely on women, recent research has uncovered a surprising culprit in recurrent miscarriages: faulty sperm. While traditional medical views have focused on the health of the mother, studies now show that male fertility may be just as crucial when it comes to preventing pregnancy loss. This discovery sheds light on a new dimension of the grieving process for couples, where both partners need support in navigating the loss.
Recurrent Miscarriage and Male Sperm Health
Recurrent miscarriage, which affects roughly 1 in 50 couples, is defined by the loss of three or more pregnancies before the 20th week. For many years, medical professionals focused their attention almost entirely on the woman’s health, looking for conditions like immune problems, infections, or hormonal imbalances. However, recent studies, such as one led by Dr Channa Jayasena at Imperial College London, have highlighted the importance of male sperm health in these pregnancies.
Dr Jayasena’s research uncovered that men whose partners had experienced recurrent miscarriages had sperm with significantly higher levels of DNA damage compared to men with no history of miscarriage. This damage is caused by “reactive oxygen species,” molecules that are typically used by the body to protect sperm from infection. However, when these molecules are present in excess, they can harm sperm, ultimately affecting the pregnancy.

Changing the Blame Narrative
For many years, miscarriage was almost exclusively seen as a woman’s issue. Doctors, researchers, and society at large often assumed that the cause of miscarriage was rooted in the woman’s health, whether due to hormonal imbalances, age, or underlying medical conditions. This led to women bearing the heavy burden of blame, often carrying the emotional and physical weight of miscarriage alone.
However, studies like the one led by Dr Channa Jayasena are slowly changing this narrative. For the first time, the role of male fertility and sperm health in miscarriage is being acknowledged, leading to a broader, more inclusive understanding of the causes of pregnancy loss. This shift is crucial not only for couples who are experiencing miscarriage but also for society as a whole.
The fact that research is now focusing on the role of men in miscarriage challenges the traditional, one-sided view that women are solely responsible for pregnancy outcomes. It opens the door to a more balanced approach to fertility, where both partners are encouraged to take responsibility for their health and seek solutions together. This can help alleviate some of the stigma and shame that women have historically faced, empowering both partners to support each other and seek medical help as a team.
As more studies emerge, there is hope that the stigma surrounding miscarriage will continue to decrease, and that men will no longer be left in the shadows when it comes to understanding and addressing the causes of pregnancy loss.

The Impact on Couples
The impact of recurrent miscarriage is devastating for both partners, but it’s essential to understand that men can experience similar feelings of grief and helplessness. The research into male sperm health has brought to light the fact that men are often left out of the conversation when it comes to miscarriage. While the physical trauma of miscarriage directly affects women, men can also experience a sense of loss and guilt, especially when it’s discovered that sperm quality may be a factor.
As a couple, it’s vital to support each other through this difficult time. Open communication is key in helping both partners process their grief. Acknowledging the pain each person feels, and discussing potential causes such as sperm health, can bring some clarity and allow both partners to work together towards healing.
Moving Forward & Supporting Each Other
Recurrent miscarriage can be a deeply isolating experience, but the emerging recognition that both partners play a role in the process is a crucial step in supporting the couple as a unit. By working together to address male fertility, seeking medical advice, and supporting each other emotionally, couples can move forward with a sense of shared responsibility and a greater understanding of the challenges they face.
