Baudelocque is known for making obstetrics a scientific discipline in France. He advanced and popularized the methodology of William Smellie (1697–1763), who modernized obstetrical practices in England in the 18th century. Baudelocque is credited for correcting errors regarding childbirth and wrote a popular book on midwifery. He refined André Levret's (1703–1780) "pelvic forceps" and constructed a pelvimeter for use in obstetrics. His pelvimeter were anthropometric calipers used to measure external pelvic dimensions.

In England, William Smellie developed a method for measuring internal pelvic dimensions." - (en.wikipedia.org 11.02.2022)
