This app AMHer is divided into three parts; Fertility Potential, Reproductive Preservation and Physiological Tracking. Fertility potential is based on the results of the AMH test and the age at the time of the test to determine whether the ovarian storage is normal and the age of the ovaries. When you test your anti-Mullerian hormone every year and keep using this app, you can get a personal AMH trend graph. One is to understand the status of one's ovaries, and the other is helpful for family planning. It can also predict the number of eggs to be retrieved and the success of embryo development during artificial reproduction. Reproductive Preservation is here to help people who are considering egg and sperm cryopreservation make their decision. A bonus is provided through a questionnaire survey to determine whether there is a demand for frozen sperm eggs. This can help men and women increase their likelihood of having children. Reproductive preservation, this need is closely related to personal age, marital status, nature of work and life pressure. The last part is closely related to personal health status. Both men and women can use this to record the values ​​obtained from annual health examinations. There is more in-depth tracking of women’s physiological status, such as menstrual cycles, ovulation day predictions and abnormal physiological functions, to achieve a deeper understanding.
