Male menstruation

Male menstruation is a term used colloquially for a type of bleeding in the urine or faeces, reported in some tropical countries. It is actually caused by parasite infestation of the urinary tract or intestines by Schistosoma haematobium, and cases of it are actually schistosomiasis, formerly known as bilharziasis. In some tropical peoples that work in wet places such as rice fields, most boys pick up Schistosoma, and start the bleeding, about puberty when they start working in the rice fields, and uneducated locals think that it is normal and refer to it as the male equivalent of female menstruation, and call it by their native language word for "menstruation".[1][2]

In at least one case, it was reported that a boy in an affected area started work in a factory instead of the rice fields, and so did not pick up Schistosoma, and did not develop the bleeding, and his father took him to a doctor asking for investigation of primary amenorrhoea.[citation needed]

This is to be distinguished from genuine menstruation in:

  • An anatomically intersex human who has a functioning menstruating womb but external sexual organs which are on the male side of ambiguous in form.
  • Trans men
  • Some men with the rare (about 1 in 100,000) condition persistent Müllerian duct syndrome where a womb has developed in a male fetus.
