UTIs in men are usually transmitted to women through sexual intercourse. So don’t have sex during an episode of UTI, and if you do, be sure to wear a condom throughout. UTIs in men that are trichomoniasis are very contagious because trichomonas is very viable in an in vitro environment. It can be transmitted not only through sexual intercourse, but also through bath tubs, baths and swimming suits, so it is very easy to transmit this disease to women. In addition, if a man has non-gonococcal urethritis, the pathogens are chlamydia and mycoplasma, which can be latent in the mucous membrane of the urethra and then invade the spouse through sexual intercourse, so it is contagious. There is also gonococcal urethritis and syphilis, which can be transmitted to women. So during an episode of UTI, couples must avoid sexual intercourse.
