Researchers have suggested that symptoms such as irritability are often unfairly blamed on a woman's period when other factors such as stress or a lack of support may be to blame, the Daily Mail reported.
Premenstrual syndrome (PMS) also called PMT or premenstrual tension is a collection of physical and emotional symptoms believed to be related to a woman's menstrual cycle.
Researchers from the University of Toronto assessed a number of studies relating to PMS.
They concluded that the studies "failed to provide clear evidence in support of the existence of a specific premenstrual negative mood syndrome".
"The idea that any emotionality in women can be firstly attributed to their reproductive function - we're sceptical about that," lead researcher Dr Sarah Romans was quoted as telling The Atlantic.
Romans and her colleagues assessed more than 40 studies relating to PMS. While many found some association with mood at various times of a woman's cycle, there was no clear pattern as to which part of the cycle was affected and sometimes no relationship at all.
Thirty-six per cent found no association between mood and the menstrual cycle.
Another 42 per cent "found an association of negative mood in the premenstrual phase, combined with another phase of the menstrual cycle".
Only 13 per cent found an association between negative mood and the premenstrual phase.
This suggests that hormonal fluctuations related to the menstrual cycle aren't necessarily to blame.
And "when there is a menstrual cycle tie-up it's actually perimenstrual - the premenstrual (3-5 days before menstruation) and the menstrual phases together - not purely premenstrual," added Romans.
"I think this can be seen as the modern day equivalent of the old wandering womb notion
