From: A pilot trial of large versus small diameter needles for oocyte retrieval
Plots for standard (17 Gauge) needle and thin (20 Gauge) needle and cycle data. (a) Oocyte yield did not differ between the two needles (p = 0.50). (b) The number of oocytes per the number of aspirated follicles did not differ between the standard and thin needles (p = 0.23). (c) Operating time significantly increased, by an average of 3.3 minutes per ovary (p = 0.002) using the thin needle in comparison to the standard needle. The asterisk indicates statistical significance (Wilcoxon Matched-Pairs Signed Ranks test).
