‘With CORA’ is a Cycle-Observation-Ring-Application for vaginal use. The cycle monitor calculates the moment of ovulation. It is important to understand that ovulation only occurs once a month. This is the only moment for a woman to get pregnant. Spermatozoa can survive up to 3-5 days within the body. An ovum only lives for about 24 hours. Knowing the fertile days is therefore crucial. Similar devices are a constant and daily reminder of not succeeding to get pregnant. ‘With CORA’ is designed with the intention: Wear to forget”. The cycle monitor needs to be inserted inside the vagina. At the end of the vagina is a cavity which is big enough to house the cycle monitor. The monitor measures by means of a temperature sensor the Basal Body Temperature (BBT). When ovulating the BBT shall increase with about 0.4 Degrees Celsius and shall decrease the first day of the menstrual days. The cycle monitor shall be inside the vagina until the first day of the menstrual days. During the menstrual cycle the monitor can be cleaned and charged. The day after the menstrual days the cycle monitor can be placed back inside the vagina. This is done by squeezing in the sides of the cycle monitor, placing it inside the vagina and pushing it with one finger further inside to the back. Due to its placement in the back, it is also possible to have intercourse while wearing the device. ‘With CORA’ does not only exist of a cycle monitor, but includes a charger and a mobile phone application. When ovulating the user will receive a notification saying that the fertile days are coming up. This way the couple has enough time to prepare to be intimate with each other. Because you will receive a notification you do not have to check daily if you are ovulating. This provides a less stressful situation. Although this project is based on couples who want to conceive, ‘With CORA’ can also be used by women who want to be in more control of their menstrual days or women who do not want to get pregnant. The cycle monitor is intended for couples who tend to get pregnant. By placing the cycle monitor inside the vagina and around the cervix the basal body temperature can be measured.
