Chlamydia trachomatis was isolated from multiple genital sites in 30.9% of infertile women with tubal infertility, suggesting tubal colonization may occur asymptomatically.

This study investigated whether Chlamydia trachomatis infection could be isolated from different parts of the female genital tract and how those findings related to tubal damage in 105 infertile women undergoing laparoscopy, using multiple specimen cultures from the cervix/urethra and from upper-tract sites including endometrium, peritoneal fluid, and the tubal lumen. Chlamydia was isolated from at least one site in 30.9% of women with tubal infertility, 12.1% with unexplained infertility, and also in smaller proportions of women with acute salpingitis or with endometriosis/uterine malformations; importantly, most positives had upper-tract colonization alone or involved one or both tubes, and only one positive woman showed laparoscopic signs of acute pelvic infection. The authors concluded that cervical cultures were inadequate to exclude tubal infection and that tubal mucosal colonization can occur without symptoms or laparoscopic signs. This paper is centrally about endometriosis only as part of its control group composition (a subgroup of women with endometriosis/uterine malformations was included for comparison when assessing silent chlamydial isolation in infertile women).

Abstract

Several studies have shown that previous chlamydial genital infection, reflected by serological markers, is strongly associated with tubal damage leading to tubal infertility. In 105 women undergoing laparoscopy, multiple samples were collected from the lower (urethra and cervix) and upper (endometrium, peritoneal fluid, tubal lumen) genital tract, in order to isolate Chlamydia trachomatis in cell culture. Chlamydia trachomatis was isolated from at least one site in 13 (30.9%) of 42 infertile women with tubal infertility, in 5 (12.1%) of 41 women with unexplained infertility, in 1 of 4 women affected by acute salpingitis and in 1 (5.5%) of 18 women with endometriosis or uterine malformations. The latter group was the control group. Thirteen (65%) of the 20 positive women harboured Chlamydia trachomatis in their upper genital tract alone and 16 women were positive in one or both tubes. Only one of the positive women showed laparoscopic signs of acute pelvic infection. Four of the 5 positive women with unexplained infertility harboured Chlamydia trachomatis in the tubal lumen. This study confirms that chlamydial infection is strongly associated with tubal damage. It suggests that cervical cultures are inadequate for excluding a tubal infection and that chlamydial colonization of the tubal mucosa is possible in the absence of symptoms and laparoscopic signs of active infection.
