Information about Marc Breedlove

S. Marc Breedlove (born 1954) is currently the Barnett Rosenberg professor of Neuroscience at Michigan State University in East Lansing, Michigan. He was born and raised in the Ozarks of southwestern Missouri. After graduating from Central High School (Springfield, Missouri) in 1972, he earned a bachelor's degree in Psychology from Yale in 1976, and a Ph.D. in Psychology from UCLA in 1982. He was a professor of Psychology at the University of California, Berkeley from 1982-2002, moving to Michigan State in 2001. He works in the fields of Biological Psychology and Neuroendocrinology. In numerous papers, he has demonstrated that steroid hormones and sexual behavior affect the developing and adult spinal cord and brain. He also reported that lesbians have a more masculine digit ratio than do straight women [1] , a finding that has been replicated in his [2] and many other labs [3] [4] [5] [6] [7] [8] [9] [10] and which indicates that lesbians, on average, are exposed to more prenatal testosterone than are straight women. This finding joins many others that biological influences, such as prenatal testosterone and fraternal birth order[11] , act before birth to affect the later unfolding of human sexual orientation. Copies of these papers, and others, can be obtained at his lab home page listed below. He has co-authored textbooks in Biological Psychology [12] and Behavioral Neuroendocrinology [13]. He is a member of the Society for Behavioral Neuroendocrinology and the Society for Neuroscience.
