The Parkes lecture: controlled ovarian stimulation in women.
Recent advances in knowledge of the endocrine and paracrine mechanisms that regulate human ovarian folliculogenesis have been parallelled by the introduction into clinical practice of new drugs that can be used safely and effectively to stimulate ovarian function in infertile women. Most notably, recombinant DNA technology has been applied to the production of molecularly pure forms of the gonadotrophins, FSH and LH, opening the way to the development of improved strategies for manipulating the ovarian paracrine system. The clinical objectives of controlled ovarian stimulation fall into two categories, depending on patient needs: (1) induction of multiple follicles from which mature oocytes can be harvested for use in assisted reproduction protocols such as in vitro fertilization and embryo transfer; or (2) induction of spontaneous ovulation of a single mature follicle so that conception might occur in vivo. This review summarizes the physiological principles upon which the use of gonadotrophins for clinical purposes is based, highlighting new opportunities for improved treatment as a result of the availability of recombinant FSH and LH.
