Secreta mulierum et virorum (cum commento).

This work on the physiology and procreative "secrets" of women was attributed to Albertus Magnus, but is now thought to have been written by one of his disciples. It was one of the most widely printed medical works in the 15th century, of which 60 different, and sometimes augmented, printed editions are catalogued in the ISTC.
