Yes, according to Dr. Susan Bard, a New York City-based dermatologist. She writes in an article on Healthline.com that a variety of studies have found testosterone to be significantly decreased in people with psoriasis.
In men, lower levels of testosterone are associated with decreases in:
- Sperm production.
- Sperm motility (movement).
- Sexual functioning (ability to achieve or maintain an erection).
Psoriasis is an autoimmune disorder that increases systemic inflammation. Bard writes that the link between psoriasis and decreased fertility may be due to that inflammation and how it affects the production of sex hormones.
If you have psoriasis or other autoimmune disorder, she suggests these lifestyle modifications:
- Exercise regularly.
- Get adequate rest.
- Eat more anti-inflammatory foods, like vegetables, fruits, nuts, and fish.
- Avoid processed foods and excess sugar.
- Reduce stress.
- Quit smoking and limit alcohol.
