This study is looking for two groups: healthy women with proven fertility and women with unexplained infertility (no known reason for not getting pregnant). Researchers want to study cervical mucus to find biomarkers that might help understand fertility better.
This study collects urine samples and menstrual-cycle information from women who are actively trying to conceive. It aims to understand fertility patterns and may help researchers improve future fertility-related care.
This study looks at “biomarkers” (test signals in your blood or cycle data) to better judge how ready the womb lining is during IVF. It compares two types of IVF hormone setups to see which approach best matches endometrial receptivity and supports successful embryo transfer.
This study looks at how your natural menstrual cycle affects heart function and hormone levels. It may help doctors better understand fertility treatments.
This study looks at how progesterone levels change in the early part of the luteal phase (after ovulation) when ovulation is triggered by an hCG injection in a natural cycle. It may help women undergoing routine ovulation induction understand how their body responds.
This research study uses MRI scans to learn how the uterus (womb) naturally changes during your menstrual cycle. Understanding these changes better may help doctors improve fertility treatments and diagnose problems earlier.
