A method for evaluating human tubal motility in vivo: a new approach for infertility investigation.
The motility of the Fallopian tube plays an important role in the gametes and embryo transport. Disorders of the tubal motor function may be involved in a great number of patients with unexplained infertility. The aim of this study was to develop a method to measure the tubal motility by means of an hysteroscopic approach in humans. The following motor parameters were evaluated: 1) the basal pressure of each 1 cm tract of the tube; 2) amplitude and frequency of the tubal contractions; 3) the uterine intraluminal pressure eight patients in the follicular phase (FP group) and 8 in the luteal phase (LP group) of the menstrual cycle, were studied. The duration of the motility recording session was 12 +/- 3 minutes (range 7-19 minutes). No significant differences were shown between the two groups of patients, and no differences were found between the recordings obtained from the right and the left tubes.
