Abstract
A young woman with a history of a septic abortion and left oophorectomy for a dermoid cyst was investigated before and after laparotomy with regard to the function of the corpus luteum. At laparotomy the remaining right ovary was surrounded and fixed by thick adhesions around the ovary. The adhesions were removed. During two regular menstrual cycles before operation, low plasma levels of progesterone were found during the luteal phase. After the removal of the adhesions normal plasma levels of progesterone were found. The urinary excretion of oestrogens also improved. Severe pelvic adhesions might be one cause of insufficient luteal function.
