Cycle diagnostics and therapy monitoring for conception attempts with OvulaRing

OvulaRing is a temperature measurement ring for cycle and fertility diagnostics that has been subjected to multiple clinical tests and is approved throughout Europe. With the aid of a biosensor, which takes the core body temperature inside the vagina every 5 minutes, the temperature progression within the cycle is illustrated in the form of a cyclofertilogram and can be evaluated using a CFG score. The measurements are saved in a web-based database and evaluated with the aid of medical algorithms. The continuous (circadian, circamensual) measurement of the core body temperature replaces the individual measurement of various parameters in the cycle in use previously. This enables a clear statement to be made regarding the cycle health of the woman. For gynaecological practice this enables improved cycle diagnostics and therapy monitoring of attempted conception. Hormonal cycle disorders can be identified at any early stage and unnecessary examinations or premature therapy at a fertility clinic thereby avoided.

Simplified cycle diagnostics with the OvulaRing doctor account

A doctor login to the web-based OvulaRing software gives you the opportunity to gain simple access to the data of your patients. You can simply select the accounts made available by the patients and use the data for individual (telemedical) diagnostics. For each cycle of the patient a so-called cyclofertilogram (CFG) is produced with information of length of cycle, length of the individual cycle phases, ovulation time point and fertility window. In addition, a CFG score is identified for each cycle. This categorises the various cycle types and enables the medical assessment of the cycle as well as the comparison of different cycles at a glance.
