The biology of the ovary – honouring the contributions of Ken P. McNatty and Rex J. Scaramuzzi

This Collection celebrates the work of Rex Scaramuzzi and Ken McNatty, two passionate researchers in the field of reproductive biology. Their impact was most profound in the area of ovarian biology in livestock, and that was our focus when we invited original contributions from colleagues, collaborators and friends. We have also included papers previously published by Scaramuzzi and McNatty in Reproduction, Fertility and Development. The coordinators of this Collection and authors of this foreword are co-Editors-in-Chief of the journal. To mitigate any potential conflict of interest they had no editor-level access to this manuscript during peer review.
