[Assessment of the penetration of culture media in uterine cavity as an effect of cervical lavage before embryo transfer: prospective and observational study of samples obtained in hysterectomy].

Cervical lavage used to remove and cleaning some of the scale elements as well as cervical mucous during embryo transfer has been a regular practice in many reproductive centers worldwide. However, the microenvironment influence using these techniques will or not be detrimental in the embryo development. Under this issue, a prospective study was doing in 16 patients (underwent hysterectomy). A cervical lavage was performed previous to the procedure similar to the embryo's transfer step, subsequently cervical invasion was checking. The age was 36.4 +/- 8.6 years, preoperatory diagnosis was abnormal uterine bleeding (n = 4), myomata (n = 4), adenomiosis (n = 4), endometrial polyp (n = 3) and chronic pelvic pain (n = 1). Uterine weight was 127.5 +/- 55.4 g with a surgical time of 48.8 +/- 12.5 minutes. Medium in the uterine cavity was founded in only one case. We believe that cervical lavage is a secure technique in embryo transfer.
