Yes, poor sperm quality can contribute to miscarriage. Research indicates a link between faulty sperm, particularly sperm with damaged DNA, and miscarriage, including recurrent miscarriages. While typically attributed to maternal health issues, studies show paternal factors, specifically sperm quality, play a significant role.
Understanding the Connection
Several studies and reports highlight the connection between sperm quality and miscarriage:
- Damaged DNA: Sperm with damaged DNA significantly increases the risk of miscarriage. Tommy's research supports this finding.
- Poor Sperm Quality: Poor overall sperm quality is linked to both miscarriage and recurrent miscarriage. This includes factors beyond just DNA damage, affecting the sperm's ability to fertilize an egg and sustain a healthy pregnancy. Examen Lab emphasizes the importance of sperm DNA testing in assessing this risk.
- Recurrent Miscarriages: A man's sperm may be an underlying cause of repeated miscarriages, a factor often overlooked in favor of focusing on the mother's health. Fakih IVF and Imperial College London research both support this.
It's important to note that while poor sperm quality can contribute to miscarriage, it's not the sole cause. Other factors related to both the egg and the mother's health also play a crucial role.
Further Considerations:
- Genetic Factors: Problems with the sperm's genetic material are a significant concern.
- Sperm Analysis: A semen analysis can assess sperm quality and DNA integrity.
- Consult a Fertility Specialist: For couples experiencing recurrent miscarriages, consulting a fertility specialist is recommended.
