Treatment of premature ovarian failure trial: description of an ongoing clinical trial.

Premature ovarian failure is a relatively common clinical condition, and carries important long-term health consequences. Estrogen replacement is recommended to alleviate unpleasant hypo-estrogenic symptoms and reduce long-term health risks. However, the most suitable form of estrogen replacement, and the exact effects of no treatment, is unknown. Surprisingly, little research has been carried out in this area. We describe the design of an ongoing clinical trial that will address these issues so that we can begin to provide evidence-based care for affected women.
