Stress Q&A by Dr. Stöppler

How does stress impact sperm motility?

Answer:

The published data on stress and its potential effects on semen are not conclusive. While some studies have shown that chronic stress can be associated with a lowered total sperm count and impaired semen quality, other studies have shown that emotional stress has little effect on semen quality.

There are many causes for an abnormal semen analysis (lowered sperm count and/or abnormalities with sperm morphology [appearance] or motility), including both genetic and environmental factors. In some cases, it is not possible to determine the exact cause of decreased sperm mobility.

Thank you for your question.
