Abstract
A search of past and current articles on ovarian physiology and premature ovarian failure (POF) using MEDLINE was performed in order to present an overview of clinical manifestations, necessary laboratory investigations, possible etiologies and treatments for POF.
POF is defined as gonadal failure before the age of 40 years. Initially, POF was thought to be permanent, but it is now believed that spontaneous remissions and even pregnancies are possible in affected women. In most cases, the etiology of POF remains elusive, but several rare specific causes have been identified. Although the etiology of POF is heterogenic, the treatment principles are the same. Hormone replacement therapy (HRT) is still the cornerstone of treatment. The only proven method of obtaining a pregnancy in patients with POF is fertilization of a donor oocyte. Cryopreservation of oocytes has worked well in animals but awaits refinement before it can be applied routinely to humans with prodromal POF, or to patients before chemotherapy or irradiation in order to save their oocytes for future fertilization.
New alternatives to traditional HRT and methods of fertility preservation are under development, but understanding of the basic pathophysiology of POF is necessary for the development and use of innovative treatments.
