Well, this explains a lot.
"A quarter of British men believe that they experience a monthly 'man period', according to new research.
As part of a study of 2,412 people (50pc men and 50pc women), male participants were asked if they frequently suffered the same common side effects of premenstrual syndrome (PMS) that women experience during their menstrual cycle, including tiredness, cramps and increased sensitivity.
And whilst 26 per cent of men revealed that they did experience these feelings on a regular basis, perhaps a more shocking statistic is that 58pc of their female partners believed them.
Furthermore, all female respondents whose partners claimed to experience 'man periods' were asked whether or not they offered any special support to their partners during these times, and 43 pc admitted that they did.
When asked how they had done so, the most commonly cited ways were "try and cheer him up" (44 pc) and "walk around on egg shells" (39 pc). Of those who didn’t believe their partners, 33 pc admitted to telling their partner to "man up".
Men identified several PMS-related symptoms as indicators of their 'man periods', from constant hunger to general irritability.
Increased cravings, tiredness and a "bloated" feeling were also reported, with 12 pc confessing that they were "more sensitive about personal weight". 5pc of respondents even reported suffering from "menstrual cramps".
According to the poll, commissioned by vouchercloud.co.uk, the average British man who believes he has a ‘man-period’ spends an additional £81.53 on food and snacks per month, compared to those who don’t suffer from the much debated biological phenomenon."
