Subtle variations in tubal anatomy in infertile women

The frequency of tubal variations was recorded in 100 infertile and 100 fertile women at cesarean section. The infertile women had significantly more tubal/pelvic anatomical variation than did their fertile counterparts. Fimbrial agglutinations (25%), accessory tubes (13%), accessory ostia (10%), phimoses (13%), and sacculations (7%) were found more commonly in the infertile women. Paratubal cysts were found with equal numbers in both groups. There was no statistical difference in history of sexually transmitted disease/pelvic inflammatory disease (PID) or endometriosis. No significant relationship between a positive PID history and fimbrial agglutination was found; the majority of agglutinations were present with no associated adhesions.
