OvulaRing identifies your

fertile days, no matter

how your cycle ticks

You are unique, and so is your cycle

It is commonly thought that a “normal” female cycle is 28-32 days long, with an ovulation in the middle of the cycle. However, studies have shown that 70% of women do not meet this standard. Their individual cycle is shorter or longer, yet still perfectly normal. Ovulation still takes place, just on a different day and almost never in the middle of the cycle. No matter how your cycle ticks, OvulaRing identifies your fertile days and can make precise statements about your individual cycle health.

* Identification and prediction of the fertile window with a new web based medical device using a vaginal biosensor for measuring the circadian and circamensual core body temperature. Regidor PA., Kaczmarczyk M., Schiweck E., Goeckenjan M, Alexander H. Gynecological Endocrinology 2017. DOI:10.1080/095135910.2017.1390737.

** The daily conception probability is usually given from the second cycle onwards, since a learning cycle with ovulation is required for this.

*** The ovulation prognosis is usually made for the fourth cycle, since three cycles with ovulation are required as learning cycles. If the ovulation day varies by more than 8 days in the successive cycles, no reliable forecast can be given. This does not affect the calculation of the daily conception probability, which is why OvulaRing can make precise statements even with irregular cycles.
