Official title
Utility of the Endometrial Biopsy in the Evaluation of the Luteal Phase
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
When a woman becomes pregnant, the fertilized egg attaches itself to the lining of the uterus (endometrium). The endometrium is constantly changing throughout a woman's menstrual cycle in response to the female hormones estrogen and progesterone. The endometrium must have certain characteristics (be at a specific phase in its cycle) in order for the fertilized egg to successfully attach. Infertility may be caused by an "out of phase" endometrium (i.e., the endometrium doesn't have the right characteristics when the fertilized egg reaches it). The purpose of this study is to evaluate whether the endometrial biopsy is useful in predicting the potential for becoming pregnant and bearing a child.
