N2 - To examine the role of Chlamydia trachomatis infections of the cervix and abnormal postcoital tests (PCT) in a general infertility clinic, 63 consecutive patients undergoing a midcycle PCT during a routine infertility workup underwent endocervical curettage, and a 10-ml blood sample was obtained. The endocervical tissue was cultured for C. trachomatis; the serum sample was analyzed for chlamydial IgG and IgM antibodies using an indirect microimmunofluorescence assay. A negative titer was considered to be ≤ 1:8 dilution for IgG antibodies and ≤ 1:32 dilution for IgM antibodies. A good PCT was defined as ≥ 5 motile sperm per high power field (HPF). A poor PCT was defined as < 2 motile sperm/HPF, and a fair PCT was defined as 2 to 4 motile sperm/HPF. Of the 63 PCTs done, 27 (42.9%) were good, 14 (22.2%) were fair, and 22 (34.9%) were poor. All endocervical tissue cultures for C. trachomatis obtained during PCTs were negative. All IgM chlamydial antibody titers were negative (≤ 1:32 dilution), 55 (87.3%) of the patients having a zero titer. Eleven (17.5%) of the patients had negative IgG chlamydial antibody titers (≤ 1:8 dilution), none of the patients had a 1:16 dilution, and 52 (82.5%) had positive IgG chlamydial antibody titers (≥ 1:32 dilution). Thus, chlamydial infections of the endocervix are rare and not commonly associated with poor PCTs in this patient population.
