Hormone pellet implantation for the menopause and premenstrual syndrome.

Sex hormone implants have been available for almost 50 years, but only a few clinicians administer them regularly. Implants represent a physiologic mode of therapy with many metabolic advantages over other routes. Surprisingly, they are relatively ignored by physicians. This may well reflect their surgical nature, although the technique of hormone implantation is simple and fast and obviates daily oral medication. As the list of indications for hormone pellets grows, more patients will take advantage of the benefits they offer.
