Does lupus affect sexual activity and fertility in men?
Sexual activity, potency and fertility do not differ among men with lupus and those who do not have lupus. Young men with lupus have normal sexual and reproductive abilities. As men age, they normally experience a drop in their levels of androgens, a hormone that is usually present in high levels in males and lower levels in females. This drop in androgen levels occurs in men who have lupus and those who do not have lupus and can cause reduced sex drive and sexual activity.
