Faulty Sperm Could Cause Miscarriage

Researchers from the United Kingdom (UK) say multiple miscarriages may be linked to the poor quality of a man’s sperm. According to a new study published in the journal ‘Clinical Chemistry,’ compared to men whose partners had not experienced miscarriages, the sperm of those involved in the study had higher levels of DNA damage. 

Until recently, recurrent miscarriage was thought to be caused by health issues with the mother, such as infection or immune problems, but the lead author of the study said sperm health may also have a role. The lead author of the study came from Imperial’s Department of Medicine in the UK Dr. Channa Jayasena, said: “Traditionally, doctors have focused attention on women when looking for the causes of recurrent miscarriage.

The men’s health — and the health of their sperm, wasn’t analysed. “However, this research adds to a growing body of evidence that suggests sperm health dictates the health of a pregnancy. For instance, previous research suggests sperm has an important role in the formation of the placenta, which is crucial for oxygen and nutrient supply to the foetus.”

The study team hoped these findings may open new avenues to finding treatments to reduce the risk of miscarriage. A miscarriage is an event that results in the loss of a foetus during early pregnancy. It’s also called a spontaneous abortion. It typically happens during the first trimester, or first three months, of the pregnancy. Miscarriage, typically happens during the first trimester, or first three months, of the pregnancy.

Symptoms include fluid, blood or tissue passing from the vagina and pain in the stomach or lower back. It’s also common to feel sadness or grief. 

Unfortunately, the miscarriage process can’t be reversed once it has started. However, medication or procedures such as a dilation and curettage can prevent certain types of complications. In addition, counselling and support are widely available. 

The researchers investigated the sperm quality of 50 men whose partners had suffered three or more consecutive miscarriages.
