ADRENAL FUNCTION IN SUBGROUPS OF THE PCO SYNDROME ASSESSED BY A LONG ACTH TEST

Abstract
SUMMARY: Fifteen patients with the polycystic ovarian (PCO) syndrome were classified into Group A (n= 6) and Group B (n= 9) based on their LH responses to LHRH before and at 44 and 92h after administration of oestradiol benzoate. Adrenal function in both groups was assessed by comparing the hormone responses to ACTH (0.5mg twice daily for 4 days) with those obtained in nine normally ovulating women during the early follicular phase of their cycles. In Group A patients there was no significant difference from normals in the serum concentration of dehydroepiandrosterone sulphate (DHAS), 17α‐hydroxy‐progesterone (17‐OHP) or androgens (testosterone and dihydrotestosterone). In contrast, the serum concentrations in Group B were significantly higher (PPPPPPP<0.02).
