Follicular fluid recovery according to follicle diameter. The expected volume (●) and recovered volume (○) of follicular fluid from follicles of different diameters aspirated in vivo using the conventional OPU system (follicles > 8 mm) and the adapted OPU system (follicles ≤ 8 mm). The lines represent the regression curves of the expected ([^__], y = 0.0157x² - 0.1457x + 0.4115; R² = 0.99) and recovered ([---] , y = 0.0069x² - 0.0214x - 0.0258; R² = 0.83) volumes.
