Abstract

We examined variations in human endometrial microvascular perfusion across one menstrual cycle in women who had undergone tubal ligation and did not report unusual menstruation. Endometrial red blood cell flux was monitored by laser Doppler fluxmetry via a fibreoptic probe atraumatically inserted transvaginally into the uterus of each of 13 conscious volunteers. The observations obtained have been compared with those previously reported from a matched control group of women [B.J. Gannon et al., Hum. Reprod., 12, 132-139 (1997)]. Women who had undergone tubal occlusion for sterilization exhibited greater endometrial perfusion during menstruation (cycle days 0-5), at the time of ovulation (cycle days 13-16) and in the late secretory phase (cycle days 23-28) than occurred in controls. In addition, vasomotion in the study group was lower than that in controls in the early and late secretory phase (cycle days 17-22 and 23-28). Tubal occlusion appeared to alter endometrial perfusion. It is possible that the reported menstrual changes in women following tubal ligation are a consequence of altered endometrial perfusion; a possible causative relationship is discussed.
