title: Oestrogen treatment and subsequent pregnancy in two patients with severe hypergonadotrophic ovarian failure.
abstract: This report describes in detail the histological and hormonal findings in a patient with Turner's syndrome (45,XO) and a patient with premature menopause (46,XX), who both conceived after withdrawal or reduction of substitution therapy with oestrogens. The aetiology of severe hypergonadotrophic ovarian failure is discussed, and theories regarding a possible relationship between the oestrogen treatment and subsequent pregnancy are hypothesized.
