Dr. Andrew Wolfe is an associate professor of pediatrics and an assistant professor of physiology at the Johns Hopkins University School of Medicine. 

An endocrinologist, Dr. Wolfe serves as the director of research training in endocrinology in the Division of Pediatric Endocrinology at Johns Hopkins Children's Center. He also is the director of training in basic science for the Endocrine Diabetes and Metabolism Training Program.  

Dr. Wolfe earned his doctoral degree in neuroscience from Northwestern University and completed a research fellowship at Boston Children’s Hospital. Prior to joining the Johns Hopkins faculty in 2007, Dr. Wolfe served as both an assistant professor of pediatrics and Director of Basic Science Research in the University of Chicago’s Division of Pediatric Endocrinology.

His research aims to better understand the regulatory mechanisms of the hypothalamic-pituitary-gonadal axis. Among the body’s most important signaling pathways, this axis controls growth, metabolism and reproduction.

Dr. Wolfe’s work particularly focuses on understanding how the metabolic dysfunction of conditions such as type 2 diabetes, obesity and polycystic ovary syndrome affects reproduction and fertility—as well as the precise signaling pathways that result in those malfunctions.

Some of Dr. Wolfe’s work has yielded valuable new clues about the relationship between insulin sensitivity in the pituitary gland and ovaries and the development of infertility—findings poised to pave the way for new therapies.

Among his honors, Dr. Wolfe was elected in 2013 to the prestigious Society for Pediatric Research for his contributions to the study of childhood disease. more

Research Summary

Dr. Wolfe’s research centers on understanding the development and functional regulation of the hypothalamic-pituitary-gonadal axis, which controls reproduction. 

Because of a long-standing interest in the regulation of GnRH gene expression and in addition to performing standard in vitro analysis, his laboratory developed a variety of transgenic and knock-out mouse models that have revealed both cis- and trans-regulatory elements underlying the cell-specific expression of GnRH. 

His laboratory is also interested in understanding how metabolic status impacts reproductive function. It has long been known that states of negative energy balance are associated with infertility. These can include anorexia nervosa and can play an important component in functional hypothalamic amenorrhea. What has become clear in recent years is that states of positive energy balance, such as obesity and type 2 diabetes, are also associated with reproductive dysfunction. 

His laboratory has developed a mouse model of obesity-induced infertility. Used in conjunction with mouse models of tissue-specific gene deletion, they are able to probe the role of various molecular signals mediating the effects of obesity on reproductive function.
