ABSTRACT
Endometrial biopsy was used to study the luteal phase in patients with Fallopian ring (Yoon ring) tubal ligation. Luteal phase insufficiency was found in 9.3% of patients in the study group and in 3.4% of patients in the control group. THe differences are statistically not significant (p = 0.5). The patients with histological evidence of poor luteal phase after tubal ligation presented with oligomenorrhea and dysfunctional uterine bleeding. These results exclude the possibility of some interference with the utero-ovarian circulatory system caused by Fallopian rings.
PIP: A study of the luteal phase of patients with tubal sterilizations in which the Fallopian rings 2 incision technique was used was conducted to determine the extent of luteal phase insufficiency caused by the procedure. Corpus luteum activity of 32 patients who had tubal sterilizations for a period of 12-15 months and of 29 patients awaiting the procedure was studied using endometrial biopsy. Increased frequency of luteal phase insufficiency after tubal sterilization was not statistically present. The condition was found in 3 patients in the study group (9.3%) and 1 patient in the control group (3.4%). The patients with luteal phase insufficiency after tubal ligation presented with oligomenorrhea of dysfunctional uterine bleeding. The results do not support the hypothesis that Fallopian ring tubal ligation interferes with the utero-ovarian circulatory system as suggested by other research. To avoid disturbance of the corpus luteum or enhance the success of future reanastomosis, the use of Hulka clips or Yoon rings is advised.
