Approx. 10% of all women worldwide have an unfulfilled desire for children
70% are using contraception. 16 billion USD market for contraceptives in 2013.

Determining body core temperature as a biomarker has allowed us to develop a unique gynecological and endocrinological method for menstrual diagnostics, which we have launched onto the market as OvulaRing.
We have worked together with the gynecological departments at the universities of Leipzig and Dresden in conducting medical studies on a total of 158 infertility patients. Our studies have provided new medical findings on ovulation and variation in the menstrual cycle (Alexander 2015/Regidor 2017) from the 470 menstrual cycles evaluated.
We found that almost 70% of women ovulated outside the expected time window (day 14) despite a healthy biphasic pattern. The new findings have demonstrated the variability in menstrual cycles, and that every woman is unique in her fertility pattern.
Core body temperature serves as an indirect endocrinological biomarker in a variety of application areas in gynecology. These especially include diagnostics in an individual menstrual cycle by identifying the day of ovulation and fertile phase toward optimizing conception, treatment during in-vitro fertilization, and support for safe hormone-free contraception. Current studies are currently examining whether core body temperature might also contribute to determining risks such as miscarriage and other pregnancy disorders during early pregnancy.

OvulaRing is our first medical diagnostic innovation to fight unfulfilled desires for children-for more rapid recognition of possible menstrual cycle disorders and individual treatment decisions.
OvulaRing provides a novel method for accurate endocrine cycle diagnostics based on continuous body core temperature measurement. OvulaRing is the first that is able to map the entire cycle for exact and complete cycle diagnostics and is therefore ideal for diagnosing fertility issues.
OvulaRing is an approved medical device consisting of a vaginal biosensor and web-based evaluation software. The sensor is worn as a pessary and is unnoticeable to the user. The device continuously measures and stores core body temperature every five minutes at a total of 288 times each day. A reading device transfers the data to mobile software for evaluation using medical algorithms, with results presented in what is referred to as a cyclofertilogram. The algorithms detect individual temperature and fertility patterns, yielding reliable health information on the individual menstrual cycle. This information helps determining the length of the cycle and each cycle phase, window of fertility and time of ovulation, and current probability of conception. Apart from that, the system is able to early detect hormonal cycle disorders, such as anovulation and luteal insufficiency, for more effective treatments.
Our portfolio includes eight international patents and intellectual property rights; we are working hard on new projects and expanding our portfolio.
