The abortion rate in trans-myometrial eggs retrieval is the same as in classical transvaginal retrieval.

ABSTRACT

OBJECTIVE: This study compares the miscarriage rate of pregnancies after trans-myometrial eggs retrieval to transvaginal eggs retrieval. PATIENTS AND METHODS: In the period between January 2004 and December 2020, 13,323 egg retrievals were carried out. In 699 cases, the ovaries were unreachable. Alternative maneuvers were performed to solve this problem, but despite this, in 132 patients the technique of trans-myometrial sampling had to be used. 26 patients were excluded from the study, because of the inclusion criteria, and therefore two groups of 106 patients were selected, Group A and Group B (control). RESULTS: In the comparison between the two groups, there were no statistically significant differences in abortion rates, pregnancy rates and complications after the technique. CONCLUSIONS: This study shows that the abortion rate in trans-myometrial oocyte retrieval does not change when compared to classic retrieval, despite the sampling needle completely crossing the myometrium. Furthermore, the pregnancy rate and the complication rate do not appear to have worsened with this technique.
