Spontaneous pregnancy in a patient with hypergonadotrophic ovarian failure

A 27-year-old woman was referred to the gynaecological endocrine clinic because of infertility and secondary amenorrhoea. Serum luteinizing hormone and follicle stimulating hormone levels were raised and oestradiol concentrations were subnormal. In spite of these findings, spontaneous resumption of menstrual cycles associated with a fall of gonadotrophin concentrations was followed by a normal pregnancy.
