The purpose of this research is to study the endometrium (the tissue lining the uterus) in order to learn more about possible medical treatments for endometriosis, a painful condition in women in which the endometrium develops abnormally on the pelvic organs.
The goal of this study is to evaluate the causes of and future treatment options for endometriosis. We are asking participants to allow us to collect a tissue sample from the lining of their uterus (endometrial biopsy) at a particular point during their menstrual cycle. This study involves one to two office visits that will occur during a single menstrual cycle. Qualified participants may have the option of participating in this study up to four times (providing up to 4 biopsy samples).
You may be eligible to participate in this study if you:
- Are a woman in good general health
- Are between 18-45 years of age
- Have a history of regular menstrual cycles lasting 26-36 days when not using hormonal contraception
- Are not currently using hormonal contraception
- Are not currently using an intrauterine device or intrauterine system (IUD or IUS)
- Are willing to use a non-hormonal form of contraception during the study
- Are not currently pregnant or planning pregnancy during the study
Study participation is completely voluntary. Eligible participants will be compensated $200 for time and travel for each biopsy sample that is collected.
