Inexpensive and reusable menstrual cups are safe and as unlikely as disposable pads or tampons to leak, according to the first major scientific review of the devices, published on last week.

Some 70% of women who have tried menstrual cups said they would like to continue using them, researchers reported in The Lancet Public Health, a peer-reviewed medical journal.

Sanitary protection remains unavailable and unaffordable to many women around the world, the authors noted.

This means monthly bleeding keeps many girls and women out of school or work and puts them at risk of urinary tract infections if they use inferior products or make-do substitutes.

In some cultures, girls or women unable to conceal bleeding may face hostility, even violence.

A safe, affordable and long-lasting alternative to pads and tampons, in other words, has the potential to change the lives of millions, reported The Hindu.

“Despite the fact that 1.9 billion women globally are of menstruating age — spending on average 65 days a year dealing with menstrual blood flow — few good quality studies exist that compare sanitary products,” said Penelope Phillips-Howard, a professor at the Liverpool School of Tropical Medicine.

The new research — a review of 43 earlier studies gathering data on 3,300 women — is the first to evaluate menstrual cups.

Made from medical grade silicone, rubber or latex, the cups collect blood rather than absorb it, as pads and tampons do. They last from four to 12 hours.

In four of the studies reviewed, the cups were found to be as effective or better at collecting blood than sanitary pads or tampons.

The research showed no increased risk of infection. There were, however, five reported cases of toxic shock syndrome (TSS), a potentially life-threatening condition caused by bacteria getting into the body via foreign objects. Since the overall number of menstrual cup users is unknown, researchers could not determine how this compared with tampons, known to boost the risk for TSS, The Hindu reported.

The cup is reusable and can last for up to ten years, making it cheaper in the long run than disposable alternatives. In some places, however, the cups can be expensive, costing as much as $40 apiece, The Hindu reported.

“For consumers purchasing menstrual products, the results highlight cups as a safe and cost-effective option,” Julie Hennegan from the Johns Hopkins Bloomberg School of Public Health said in a comment, also in The Lancet Public Health.
