From: A pilot trial of large versus small diameter needles for oocyte retrieval
Plots for needle size (Standard 17 Gauge and Thin 20 Gauge), ovarian reserve (diminished and normal), and oocytes retrieved. (a) Oocytes yield did not differ between the two needles among women with diminished ovarian reserve (p = 0.17). (b) Oocyte yield did not differ between the two needles among women with normal ovarian reserve (p = 1.00). No statistically significant differences were observed (Wilcoxon Matched-Pairs Signed Ranks test).
