| Abstract: | Following various methods of tubal sterilization, menstrual disturbance have been reported. One reason for these might be a change in ovarian function caused by interruption of blood supply or nervous supply to the organ. In order to prospectively evaluate the corpus luteum function following tubal sterilization, plasma progesterone determinations were made during one menstrual period 2-3 months and even years after the operation performed by means of endothermic coagulation. The levels of progesterone in plasma during the menstrual period before the operation were used for comparison. When using endothermic coagulation as a method of sterilization there seem to be no signs of changed corpus luteum function either, months or years after the operation. |
