Women have a thick yellow-green to gray discharge from the vagina , vaginal odor, painful urination, and painful intercourse. They may also have lower abdominal pain. Men may have a water-clear discharge from the penis and painful urination, but usually have no symptoms at all. Symptoms your physician may observe When the physician does an examination, she or he will take samples of the fluid from the vagina or penis . Examining the fluid under a microscope may show the protozoans, but a more reliable method, especially for infected men, is to culture the fluid to grow the protozoans.
Antiprotozoal medication is prescribed to kill the parasite.
Both partners should be treated at the same time so one does not remain infested and reinfect the treated partner. Stages and progress Symptoms usually appear four to twenty days after infestation, but may not occur until years later in some individuals. Prevention Trichomonas can be transmitted if a person is infected, even if there are no symptoms. The best prevention, after abstinence, is the use of condoms and diaphragms.
