Endometrial Dating by Ex-vivo Imaging of Endometrial Biopsies of In-vitro Fertilization Candidate Participants

In order to assess the efficacy of using ex-vivo endometrial imaging to determine optimal time for embryo transfer, two to four separate analyses, including imaging, and the current standard method of endometrial dating (ultrasound, histological and blood tests) will be performed as well as participant's testimony. Dating by hormonal profile (blood tests) will be contingent on availability of the tests for each subject. So shall be the ultrasound test. During the analysis data will be acquired for subsequent correlation analysis. In addition, a parallel in-vivo analysis, similar in methodology to the ex-vivo analysis, may be performed via imaging by hysteroscopy.
