Women are often told to wait until their period to begin, but a new study suggests that the idea is outdated.
Men are more likely to start their periods as they get older, according to a study by researchers at the University of Sydney and Melbourne’s Monash University, in Australia.
The researchers also found that younger women were less likely to begin their periods earlier.
“The fact that men have a longer period of life is a bit of a surprise because we’ve known for a long time that men’s fertility peaks during the late 20s and 30s,” lead researcher Dr. Lisa Tosto said in a press release.
“What’s surprising is that women in the 20s are less likely than men to have a period.
This may reflect that they are getting older and perhaps they are taking longer to get pregnant, but it also means that the longer the menopage, the less fertile they are.”
The study involved 5,000 women in their 30s and 40s.
About 40% of them had had at least one period during their lifetime.
The average number of days per week they were in a normal period was about seven.
Tosto and her colleagues followed the women’s lives for eight years, recording their period cycles, their physical symptoms, their age at menopaus, and their levels of stress and depression.
Menopause is a common health issue among older adults, and the risk of developing symptoms is higher among women.
The study suggests menopa may be a warning sign of early onset of menopausal symptoms, such as fatigue and dry skin, and menopitis.
Toady Doolan, an associate professor of clinical medicine at University College London, said the findings should serve as a wake-up call to menopausal women to start getting tested for periods.
“There’s no doubt that the older you are, the more you’re likely to have symptoms of menomening symptoms, which include tiredness and fatigue, which can affect your ability to do work,” she said.
“And it can also be associated with depression, which increases your risk of heart disease, stroke and osteoporosis.”
Toado said more research is needed to know whether the relationship between menopopause and period timing is causal, or whether it may be an effect of other factors, such how long men have lived and how they are physically active.
