In accordance with the US Facilities for Illness Management and Prevention, between 1% and three% of ladies use fertility consciousness — through which a lady’s physique indicators akin to temperature are measured to foretell ovulation — as a type of contraception. Nevertheless, a study from the College of Iowa discovered that if extra girls knew about it, one in 5 would think about it as an choice.

Pure Cycles hopes to faucet into that market. The app makes use of sperm survival charges, physique temperature and menstrual cycles to foretell a lady’s fertile days. To make use of the app, a lady should take her temperature with a basal physique thermometer, which offers correct information to the 10th of a level, each morning. A purple gentle then warns if there’s a danger of being pregnant and to make use of contraception; a inexperienced gentle says it is secure to have unprotected intercourse.

Pure Cycles was developed by nuclear physicist Elina Berglund Scherwitzl, who was a part of the Nobel Prize-winning workforce that found the Higgs boson particle, a part of a mannequin that explains the elemental constructing blocks of the universe. She and her husband developed and marketed the Pure Cycles algorithm after not discovering a passable hormone-free contraceptive choice available on the market.

Launched in Sweden in 2014 as a fertility app to assist girls who’re attempting to turn out to be pregnant, the app obtained approval final 12 months as an authorized contraceptive from the UK’s Medicines and Healthcare merchandise Regulatory Company.

“The approval of Pure Cycles by the FDA establishes a regulatory pathway for these sorts of units/apps,” mentioned Polis, which she hopes will result in a “stronger regulatory surroundings,” not a weaker one.

In January, a hospital in Sweden known as the app’s reliability into query. Södersjukhuset hospital in Stockholm mentioned that at least 37 women sought abortions at its services after utilizing Pure Cycles as a contraception methodology. Pure Cycles confirmed the report, saying on the time that the numbers “should not stunning given the recognition of the app and [are] in keeping with our efficacy charges,” including that undesirable pregnancies are an “unlucky danger with any contraception.”
Some girls have gone public with their mistrust. One wrote about her expertise with Pure Cycles in an article in The Guardian headlined “I felt colossally naive’: the backlash towards the contraception app.” After 4 months utilizing the app, she grew to become pregnant and had an abortion.
“As somebody who did not report my very own being pregnant final 12 months, preserving it secret even from my mother and father, I ponder what number of extra there have been,” Olivia Sudjic wrote. Because it turned out, Sudjic had polycystic ovary syndrome, a hormonal imbalance that causes irregular menstrual cycles, infertility and pelvic ache.
