title: Examination of changes caused by tubal sterilization in ovarian hormone secretion and uterine and ovarian artery blood flow rates.
abstract: OBJECTIVE
  To examine the changes caused by tubal sterilization (TS) in ovarian hormone secretion and uterine and ovarian circulation.
  
  
  METHODS
  Tubal sterilization was performed by minilaparotomy and laparoscopy methods in 36 women. Blood samples were taken for hormonal tests on Preoperative Day 3 (D3) of the menstrual cycle, on Postoperative Days 13-15 (periovulatory period) of the same cycle and on D3 in the 1st and 6th months post-TS. Uterine and ovarian artery blood flow rates of the women were measured on the same days as hormonal tests by transvaginal color Doppler ultrasonography (TVCDUSG). The control group was composed of 15 volunteers in the same age group who preferred the barrier method and who had the same TVCDUSG and hormonal analyses in the same periods.
  
  
  RESULTS
  There was a decrease in the uterine and ovarian artery pulsatility index (PI) measurements and an increase in serum luteinizing hormone (LH) and estradiol (E2) values during the periovulatory period as compared with preoperative and postoperative menstrual measurements in all groups. There was no difference between baseline uterine and ovarian artery PI and serum follicle-stimulating hormone, LH and E2 values and those measured on D3 of the menstrual cycle in the 1st and 6th months post-TS.
  
  
  CONCLUSIONS
  The 6-month postoperative follow-up of groups that had undergone different TS methods showed no difference in uterine or ovarian artery blood flow rates or ovarian hormone secretion in comparison with baseline values.
