What do women and rhinos have in common?

The concept that human reproductive physiology is unique, and little can be learned or benefits gained by studies in other model system or exotic species is woefully out of date. The cross-fertilization that can be gleaned by furthering our knowledge about the basic biology and molecular mechanisms that regulate everyday physiological processes in other species is vast. In this review, I share how studying rhinoceros ovarian physiology, exploring novel culture techniques, and overcoming unexpected challenges that are presented by working with such unique samples has benefitted my program of research that focuses on developing fertility preservation technologies for women — and rhinoceros.
