Schenck compiled the first bibliography of gynecology, entitled Pinax auctorum in re medica, Graecorum, Latinorum priscorum, Arabum Latinobarbarorum, Latinorum recentiorum, tum & peregrinis liniguis cluentium, Exstantium, MS. promissorum vel desidetatorum: qui gynaecia, sive muliebria plento argumento sive ex instituto scriptis exceluerunt & illustrarunt. It covered writings on the subject from the earliest times to the beginning of the 17th century. This he appended to his posthumous first edition of Guinter’s treatise on gynecology. Neither Guinter's nor Schenck's work was particularly long; the entire book contains 56 pages, of which Schenck's bibliography occupies pp. 37-56.

Schenck described nearly 100 human and animal examples, illustrated with engravings by Theodor de Bry (1528-98). Most of the examples are from the 16th century. Not all the cases are teratological in the strictest sense as Schenck includes a discussion, with illustrations, of the painter and calligrapher Thomas Schweicker (1541-1602), who was born without arms, and wrote and painted with his feet.
