In vitro fertilization-intracytoplasmic sperm injection outcomes in single- versus double-lumen oocyte retrieval needles in normally responding patients: a randomized trial.
We compared the retrieval efficiency of single- (direct follicular aspiration) and double-lumen-needle (attained with follicular flushing) procedures in normal-responder IVF-intracytoplasmic sperm injection cycles. This prospective randomized study did not demonstrate a beneficial effect of double-lumen needle retrieval compared with single-needle retrieval in normal-responder IVF-intracytoplasmic sperm injection cycles in terms of retrieved oocytes, clinical pregnancy rates, and live birth rates.
