About

Dr. Martha Sofia Ortega Obando is an Assistant Professor at the University of Wisconsin–Madison, USA. Her research focuses on reproductive success in dairy cattle, including the management of genetic defects, and embryo development. Recent articles highlight the effects of various supplements on pregnancy success, the influence of sire selection on fertility, and the relationship between sperm quality and oocyte health.
