The DUTCH Cycle Mapping maps the progesterone and estrogen pattern throughout the menstrual cycle. It provides the full picture of a woman’s cycle to answer important questions for patients with month-long symptoms, infertility and PCOS. For some female patients, testing on just one day of the month is not enough. Women with PCOS, infertility, irregular cycles or no menstrual bleeding due to an ablation or partial hysterectomy, can benefit from the DUTCH Cycle Mapping.
