Follicle Structure Influences the Availability of Oxygen to the Oocyte in Antral Follicles [PDF]

Computational and Mathematical Methods in Medicine, 2011
The ability of an oocyte to successfully mature is highly dependent on intrafollicular conditions, including the size and structure of the follicle. Here we present a mathematical model of oxygen transport in the antral follicle. We relate mean oxygen concentration in follicular fluid of bovine follicles to the concentration in the immediate vicinity ...
