Chicken pox does not normally lead to sterility, but it can negatively affect male fertility for a period of time. Fever is a common symptom with chicken pox, and the fever can reduce male sperm production for up to 90 days after it ends, according to Riverside.
Infectious diseases can also cause testicle inflammation, or a condition known as orchitis. Orchitis may include testicular shrinkage and infertility. While the effects of chicken pox on male infertility are normally temporary, it is possible for a person to experience more long-term sperm production problems, according to Baby Med. If problems persist, medical attention is advisable.
