Berkeley, Calif. (AP) — Scientists at the National Institutes of Health have discovered that most menstruating men who suffer from toxic masculine shock syndrome benefit from higher doses of the male sex hormone testosterone.

“Our research underscores the universal truth that masculinity is toxic,” said lead scientist Dr. Calvo Mentiroso. “What we don’t understand yet is why menstruating transgender men experience fewer symptoms after receiving higher doses of the substance that makes men toxic.”

The study followed several thousand menstruating men who self-identified as binary, non-binary, or transgender, including three-and-a-half men who transitioned before age 10.

Results show that men were less toxic during “that time of the month” when given more male sex hormones than the control group.

“More research is necessary,” admitted Dr. Mentiroso. “For instance, we also don’t understand why transitioning individuals who identify as ‘non-binary’ only have the choice of two genders.”
