For this study, we are asking women to allow us to obtain a swab from the vagina, cervix and endometrium as well as small sample of tissue from the lining of the uterus. This sample is called an endometrial biopsy. We will look at this tissue and examine the composition of cells and other characteristics of this tissue.
We will also be obtaining a blood sample (approximately 1 teaspoon) at the time(s) we obtain the swabs and endometrial biopsy. We will perform the same tests on the blood sample described above on the endometrial biopsy.Four groups of women will be included in this study.
