Study type | Observational |
Endometrium is the lining of the uterus. It is where the fertilized egg normally implants
during pregnancy.
This study was designed to better understand the way(s) that female sex hormones (estrogen
and progesterone) cause the uterus to grow and develop. It is known that these hormones are
necessary to prepare the uterus for pregnancy, but the way the hormones work is unknown.
Researchers would like to identify the genes that are affected by female sex hormones by
using a variety of tests (in situ hybridization, immunohistochemistry, and culture of human
endometrium).
Researchers will select women who have regular monthly menstrual cycles and study them for
two cycles;
1. <TAB>The first cycle (PRE-BIOPSY CYCLE) will include daily measurements of the patient's
body temperature and progesterone measurements during the last 14 days (luteal phase) of
the menstrual cycle.
2. <TAB> The second cycle (BIOPSY CYCLE) will include measurements of urinary luteinizing
hormone (LH) to determine the day of the LH surge. Luteinizing hormone is the hormone
that causes the ovary to release the developed egg. Ovarian ultrasounds will be
performed before the biopsy to determine development of the egg. Blood tests will be
taken on the day of the biopsy to have an overall idea of the hormones circulating in
the patient's blood. An endometrial biopsy will be taken at one of three possible times
to identify endometrial products under conditions of estrogen, estrogen/progesterone, or
steroid hormone withdrawal.<TAB>

- INCLUSION CRITERIA: Healthy volunteers will be in excellent health. Only women with regular menstrual cycles (every 26-35 days) using mechanical (condoms, diaphragm) or sterilization methods of contraception will be included. Only women with a negative pregnancy test, normal physical examination and laboratory results, and a luteal phase progesterone value of greater than 4 ng/mL will be entered into this study. Women with endometriosis will be recruited from those with histologically-proven endometriosis. Except for this diagnosis they will meet criteria for healthy volunteers as stated above. Women may participate in the study on more than one occasion, but biopsies may not be performed in a "baseline" cycle. |
