A 26-year-old recently married woman, who has always had very irregular menstrual cycles varying between four and ten weeks duration, returns to the clinic one week after her previous routine review. At that time she indicated her last period had occurred six weeks previously. The results of the tests you arranged then are as follows:
Serum follicle-stimulating hormone (FSH) 3 IU/L (<13)
Serum luteinising hormone (LH) *850 IU/L (4-10 in follicular phase, 20-100 at mid-cycle)
Serum prolactin (PRL) 475mU/L (50-500)
Which one of the following is the most likely cause of her continuing amenorrhoea?
(A) Stress from her recent marriage
(B) Polycystic ovarian syndrome (PCOS)
(C) Premature ovarian failure
(D) Early pregnancy
(E) An LH-producing pituitary adenoma
