Men who exhibit symptoms of trichomoniasis can experience penile discharge, irritation inside the penis and a burning sensation after urination or ejaculation, according to WebMD. Men are often asymptomatic and only become aware of their own infections when their partners require treatment.
Trichomoniasis is the most common sexually transmitted disease in young women as of 2015, with an estimated 7.4 million new cases diagnosed each year in both genders, reports WebMD. Metronidazole, or Flagyl, is the antibiotic frequently used to treat trichomoniasis, which is caused by a small parasitic organism called Trichomonas vaginalis. All partners involved undergo antibiotic therapy and are advised to discontinue sexual intercourse until the infection is fully cleared in about a week in order to prevent reinfection and further spreading.
Trichomoniasis is diagnosed in men by microscopic examination of a urine sample, states Mayo Clinic. It is believed that the incubation period between exposure during intercourse and infection ranges from five to 28 days. Intercourse without a condom, multiple sexual partners, and a history of other sexually transmitted infections or a previous trichomoniasis infection increase an individual’s risk of infection. In women, a trichomoniasis episode appears to make it easier for them to become infected with HIV.
