A comparison of pain experienced during hysterosalpingography and in-office falloposcopy.

OBJECTIVE: To determine patient perception of the intensity of pain during in-office falloposcopy compared with hysterosalpingography (HSG). DESIGN: A prospective quality assurance study using a formal pain scale to compare two procedures. SETTING AND PATIENTS: Patients attending a tertiary level infertility clinic. INTERVENTIONS: In-office falloposcopy or HSG using analgesics. MAIN OUTCOME MEASURES: The mean pain score and area under the pain curve experienced during each investigation. RESULTS: Using our technique, in-office falloposcopy was associated with a significantly lower mean intensity of pain and with a longer procedure. The duration of the falloposcopic examination declined significantly with physician experience. Flushing adjacent to the uterotubal ostium, ostial cannulation, and rapid eversion provoked episodes of acute pain during falloposcopy. CONCLUSION: These results support the patient acceptability of in-office falloposcopy.

Office falloposcopy; a tertiary level assessment for planning the management of infertile women.

Thirty-nine women underwent Falloposcopic examination utilizing the linear eversion catheter. Indications for examination included bilateral and unilateral proximal and distal tubal occlusive disease, assessing the residual Fallopian tube after salpingectomy for ectopic pregnancy, and unexplained infertility. Seventy-three Fallopian tubes were available for examination, of which 72 (98.6%) were successfully cannulated. Sixty-eight ampullas were successfully visualized (94.4%). The mean duration of the examination was 24.7 minutes. Where proximal tubal disease was not suspected, 30.3% of oviducts were found to have a proximal lesion and 57.5% were found to have distal intratubal disease.

Sperm numbers and distribution within the human fallopian tube around ovulation.

This study aimed to determine the number and distribution of spermatozoa within the human Fallopian tubes around ovulation. Parous women, undergoing total abdominal hysterectomy for menorrhagia, were inseminated with either partner's semen (3/10) or donor semen (7/10). Approximately 18 h later both Fallopian tubes were ligatured into ampullary, isthmic and intramural regions. These were removed and assessed for sperm content by flushing, scanning electron microscopy (SEM) or homogenization. A median of 251 spermatozoa were recovered (range, 79-1386). The number of spermatozoa within each tube was not significantly different. The ovulatory ampulla contained a significantly (P < or = 0.01) larger percentage of spermatozoa than the non-ovulatory ampulla. The number of motile spermatozoa inseminated was not significantly correlated to the number of spermatozoa recovered, but a trend was identified. The time between the onset of the luteinizing hormone surge and hysterectomy was significantly correlated (P < or = 0.01) to the number of spermatozoa within the intramural regions, but not to the tubal sperm distribution. Spermatozoa were not observed, by SEM, bound to the tubal epithelium. These data suggest that, after artificial insemination at least, sperm access to the human Fallopian tube may be controlled, but that ovulation does not affect the redistribution of spermatozoa between tubal regions and that the isthmus does not appear to act specifically as a sperm reservoir.

Recovery of artificially inseminated spermatozoa from the fallopian tubes of a woman undergoing total abdominal hysterectomy.

Investigation of the process of sperm transport within the human female reproductive tract must involve the recovery of spermatozoa from the oviducts of women post-coitum or insemination. This case report describes the insemination of a 40-year-old woman with her partner's semen and the subsequent recovery of spermatozoa from her Fallopian tubes, removed at hysterectomy, 2 days post-ovulation. The number of spermatozoa present within the tubes and their location was ascertained using a flushing technique and scanning electron microscopy (SEM). The total number of spermatozoa present within the flushed tube was calculated to be 142, whilst the total number of spermatozoa calculated to be present within the scanned tube was 673. The proportional distribution of spermatozoa within the tubes was virtually identical by the two techniques used. The largest population of spermatozoa resided within the ampulla (66.1% SEM, 68.3% flush), and the smallest population resided within the intramural region (14.9% SEM, 13.4% flush).
