Men can become allergic to their own orgasms.
Men can be allergic to their orgasms
Experts have discovered nearly 60 cases of men who fall ill immediately after climaxing, with symptoms including itchy eyes, a blocked nose or flu-like symptoms.
Sufferers can also experience feverishness, muscle weakness and problems with their speech and the side effects can continue for up to a week after the orgasm.
Scientists have named the condition Post Orgasm Illness Syndrome (POIS) but now think that they have found a way to cure the condition with over-the-counter pills.
Lead researcher Andrew Shanholtzer - from Oakland University in the US - wrote in the journal Urology Case Reports: "POIS is becoming increasingly recognised as a culprit among men experiencing sexual dysfunction.
"Many (health) providers do not know about it, let alone the public.
"Given it is newly being described as a condition, it is more than likely that it is underdiagnosed, with many sufferers out there."
