Menstrual patterns after laparoscopic sterilization using a spring-loaded clip

Details of the menstrual cycles in 504 women were recorded before laparoscopic sterilization with a spring-loaded clip and at six months and one year after the procedure. The operation did not affect the length of the menstrual cycle or duration of menstrual flow, nor the patient's assessment of the amount of blood losss or the incidence of dysmenorrhoea. The previous method of contraception was significantly related to subsequent menstrual patterns.
