Abstract

More than 40 years ago, the development of contraceptive vaginal rings began, based on the fact that the vaginal epithelium can absorb steroid hormones and the capacity of elastomers to release these hormones at almost constant rates. The growing interest in woman-controlled contraceptive methods has supported and accelerated the process.
