The Mystery Tradition of Miraculous Conception: Mary and the Lineage of Virgin Births by Marguerite Mary Rigoglioso is a book that details the very interesting ideas of Virgin Births and Parthenogenesis.
Dr. Rigoglioso has a great site with more resources called the Seven Sisters Mystery School. Also, several interviews are listed at InnerTraditions.
I wonder how her work relates to that of Dr. John Mack and the UFO abduction/birth phenomenons?
