Contraception. Effectiveness of diaphragm and jelly in a well-motivated group of clinic patients.

With the increasing availability of new forms of contraception it is of importance to relate data obtained with new techniques to that obtained with diaphragm and jelly. This report provides statistical information relative to incidence of pregnancy in a relatively carefully-controlled group of clinic patients. Eighteen pregnancies occurred among 659 patients who used the method for a total of 7,353 cycles.
