It is a long held assumption that women have concealed ovulation, which means that men do not know when women's menstrual cycles are in their most fertile phase. Recent empirical results have provided evidence that ovulation may not be totally concealed from pair-bonded males, but the generality and the mechanisms of the finding demand further study. To examine the possible adaptive value of the phenomenon, it is necessary to study whether the ability to detect ovulation is confined to males. We studied these questions in an experiment in which male and female raters rated the sexual attractiveness and intensity of T-shirts' odors worn by 42 women using oral contraceptives pill users and by 39 women without oral contraceptives nonusers. Males rated the sexual attractiveness of nonusers highest at midcycle. However, female raters showed only a nonsignificant trend for this relationship. Neither sex rated attractiveness of the odors of pill users according to their menstrual cycle.

Kat Grilli started using Flo — a popular period- and pregnancy-tracking app — a year ago, when she began her IVF journey to get pregnant with her husband, who is transgender. She logged onto the app to track her periods so she would know when to start IVF drugs, she said, adding that she also responded to prompts about her sexual activity, hunger and exercise. Flo was founded by a pair of Belarusian men, Dmitry and Yuri Gurski, in , and claims to have million users. When users first sign up for the app, it asks them whether they want to track their periods, pregnancies or fertility, and then requests their age, mood and symptoms and what they want to improve about their sleep, mental health, sex lives and relationships, among other topics. By agreeing to the proposed settlement, Flo did not admit to or deny any of the allegations contained in the complaint. In a forthcoming paper Gross co-authored on the ethics of the monetization of menstruation app data, she argues that health data must be understood as a form of labor rather than property so that menstruation apps become subject to regulation. They are selling our data. Madeline Kiss, a former Flo user who deleted the app once she found out the news, agreed that the company should be held responsible for compensating users affected by the breach. Jenny Grinblo, a year-old user experience designer who lives in London, reached out to the company asking for a refund for her subscription on Wednesday night.
