Neocoronaviruses may have harmful effects on various systems, including the male reproductive system. Neocollins have only been found to cause damage to the testes, which may affect male fertility, but there are no clear cases of male infertility due to neocollins. Neocollins cause damage to spermatogenic cells and may also damage the supporting cells of the testes as well as the interstitial cells, causing them to degenerate. These damages can lead to pathologic changes in the testes. In addition, neo-coronaviruses have the potential to cause testicular inflammation by triggering an immune response. As the testis is the male reproductive organ, damage to it can adversely affect male fertility. However, there are no clear reports or cases of infertility occurring in men due to infection with Neocollins. Patients are advised to consult their doctors and undergo relevant tests to confirm whether their fertility is affected.
