Infertility problems may develop in some severely infected patients by the Brucellosis virus.
A review of male patients with Brucellosis showed specific findings related to the involved organ system. They showed the most common complaints associated with Brucellosis like fever, sweating, arthritis, scrotal pain/swelling, etc. Another prospective study showed that Epididymoorchitis was detected in 12.7% of male patients, which concluded that infertility problems might develop in those patients.
However, there is no sufficient proof to say that bacteria will cause infertility problems in all men infected by the virus.
