Although it may sound contradictory, the most common symptom of chlamydia infection in men is not having symptoms at all.
A man with this condition is medically called an “asymptomatic carrier”. The problem of this condition is that neither the patient nor his sexual partner may notice the infection and it is transmitted from one to another without noticing. Another important problem of this condition is that if the infection is not treated, the patient may be an asymptomatic carrier for years and can infect all their sexual partners during that time.
More importantly, if the man is not properly diagnosed and treated for this infection, he may develop subsequent infections in the genitourinary system, which can be severe.
Many experts and international organizations recommend to treat the couple when a person is diagnosed with STIs (Sexually Transmitted Infections) to reduce the alarming rate of this infection.
