Optimal aspiration pressure of suction pump for oocyte retrieval in infertile patients undergoing in vitro fertilization.

ABSTRACT:

Background

The oocyte retrieval is a critical step in assisted reproductive technologies, including in vitro fertilization and fertility preservation. Despite evolving techniques, the optimal aspiration pressure during retrieval remains debatable, with limited in vivo human studies. Existing studies, primarily in vitro and on animals, suggest that inappropriate aspiration pressures can impair oocyte quality. This study aims to compares the effects of two different aspiration pressures, 120mmHg and 150mmHg, on oocyte recovery, damage, and subsequent embryo development and pregnancy outcomes in infertile women undergoing transvaginal ultrasound-guided oocyte retrieval.

Methods and findings

This retrospective study analyzed data from 891 women at Seoul National University Hospi
