Sterilization Effects (Thailand)


For many years, female sterilization by tubal occlusion has been practiced in developing countries. To date, there has been little research into possible side effects resulting from this procedure. This project will enable the Chulalongkorn Hospital Medical School of Thailand to investigate any abnormal ovarian disturbances and uterine bleeding caused by this method of sterilization.

Researchers tested the effects of tubal occlusion in two experiments at the Chulalongkorn University Medical School and at Siriraj Hospital. In the university study, 50 volunteers underwent suprapubic tubal ligation; application of silastic Falope Rings; or laparoscopic tubal electrocautery. In the hospital study, two hundred women had either laparoscopic tubal electrocoagulation or minilaparatomy. Both groups were followed for 12 months postoperatively; and women using conventional contraception or having sterilized partners were used as controls.

Researchers found that there were no ill effects associated with the sterilization methods tested. In the university study, it was concluded that there were no significant changes in menstrual duration and flow following the procedures. Researchers did suggest, however, that the sterilization technique chosen be one that causes the least disruption of utero/ovarian blood supply. In the hospital study, it was found that there were no significant changes in body weight, blood pressure, hematocrit, and general health in all groups. Project results were discussed at an IDRC- supported national seminar.
