Reproduction is necessary for the survival of any species. As we domesticated animals and attempted to make genetic change, it became imperative that we better understand the physiology of reproduction. Through this improved understanding, the development of reproductive technologies like artificial insemination, embryo transfer and sexing semen became possible. By studying developmental biology, a sub-field of reproductive biology, we now better understand crucial developmental periods during gestation and can make appropriate adjustments in how we manage and feed animals.
As one starts to delve into the literature explaining the physiology of reproduction, it can seem like a daunting task. Any field of study seems to have its own language, and physiologist, like most scientists, love their acronyms. To help explain some of the simple concepts in reproductive physiology, Dr. Frank Robinson at the University of Alberta challenged his students to answer several questions related to reproductive physiology in a fun and entertaining way.
