Fig. 2From: Numerical simulation of embryo transfer: how the viscosity of transferred medium affects the transport of embryosIllustration of the initial positions of the embryos in the catheter in the simulations: The small dashed-line circle represents the shape of an embryo. The 10 black dots (e1, …, e10) represent the centers of the 10 embryos used in the simulations. The shaded annulus represents the catheter wallBack to article page
