title: Chlamydia Trachomatis Infection and Tubal Infertility in Port Harcourt, Southern,Nigeria.
abstract: BACKGROUND
  Tubal occlusion remains one the commonest causes of infertility in our environment and previous pelvic infection have been implicated in the aetiology of the blockage Objective: To demonstrate prior chlamydia infection in women with tubal factor infertility and ascertain the relationship between chlamydia and tubal occlusion.
  
  
  METHODS
  This was a case-control study consisting of 188 patients drawn from the University of Port Harcourt Teaching Hospital (UPTH) Port Harcourt, South-South Nigeria.The cases were 94 women with radiologically confirmed tubal occlusion and the controls were another 94 women with intrauterine pregnancy, all screened for the presence of chlamydia immunoglobin G antibody in the serum using Immunocomb Chlamydia Bivalent IgG kit, Orgenics, Israel.Their socio-demographic characteristics and the pattern of sexual behaviour were documented in the profoma provided. Statistical analysis was done using SPSS version 17 statistical software.
  
  
  RESULTS
  The prevalence of Chlamydia antibodies was significantly higher in patients with tubal factor infertility (61.7%) than in the pregnant controls (34%) as p=0.001 and was associated with a three-fold risk of tubal factor infertility, with Odd's ratio (O.R) 3.12.
  
  
  CONCLUSIONS
  There was a risk association between Chlamydia Trachomatis infection and tubal factor infertility. Early coitarche and previous pelvic inflammatory disease were other risk factors of Chlamydia trachomatis infection found to be positively associated with tubal factor infertility.
