Male reproduction and cystic fibrosis
Men, however, do not always have the same luck. While they are also susceptible to fungal infections due to medication (also known as male candidiasis), most male infertility owing to cystic fibrosis does not come as a side effect of the symptoms of the disease.
Poor lung function, poor nutrition, and low body weight can affect sperm count and motility. However, that is also not the main cause of infertility in men with cystic fibrosis.
