Long acting contraceptive implants. An analysis of menstrual bleeding patterns.

Abstract

The menstrual patterns of women using subdermal implants of levonorgestrel and norgestrienone included in a double-blind clinical trial was evaluated by the method developed by the International Committee on Contraception Research. Women using Copper T200 randomly selected in the same clinics were used as controls. Both implant regimens were associated with a high frequency of reduced bleeding and norgestrel patients had also a high proportion of increased and irregular bleeding. Termination of use was associated to increased bleeding but not so much to reduced bleeding.
