Premature ovarian failure (POF) is common, affecting approximately 1%
of women. It is defined as gonadal failure before the age of 40 and pa
tients may clinically present with either primary or secondary amenorr
hoea. This review concentrates on the clinical aspects of POF, with se
quential discussion on the aetiology and epidemiology, clinical manife
stations and relevant investigations, concluding with an overview of m
anagement. In addition, the scientific basis for our current understan
ding of POF is summarized to provide a comprehensive overview of the d
iverse pathophysiological mechanisms that may underlie this disorder.
Despite the heterogeneity of causes of POF, the fundamental treatment
principles are the same. In this review the initiation of hormone repl
acement therapy in the younger woman and the importance of long term f
