The definition of orchitis is that of an inflammatory process affecting one or both male gonads (testicles). The causes of orchitis can be of infectious origin, traumatic or even due to the twisting of the spermatic cord. All these causes can produce a process of subfertility (diminished fertility) or infertility.
The most obvious cause of orchitis that causes infertility is mumps (caused by infection with a virus called Paramyxovirus) when it occurs in adulthood or after age 18.
When faced with a process of testicular inflammation of one or both testicles, the first treatment to be able to reverse the situation and preserve the maximum fertile capacity is to go to the doctor urgently. It should not exceed a time of 4 hours, since this will allow to establish an immediate treatment and thus preserve, in most cases, the fertile capacity of the patient.
