ABSTRACT
INTRODUCTION:
Infertility is a global public health problem that affects 15% of couples of childbearing age. Male infertility is involved in 20 to 50% of cases. These figures are sharply increasing around the world. Several factors may be responsible for this infertility with especially hormonal, genetic, toxic or infectious factors. The latter are dominated mainly by Chlamydia infection. Among the most serious complications of this infection are infertility related to urethritis, epididymitis and irreversible total azoospermia in men and tubal obstructions and ectopic pregnancies in women. STUDYOBJECTIVE:
To determine the prevalence of IgG anti-Chlamydia trachomatis in men consulting for infertility and the association between previous contact with this bacterium and the impairment of sperm quality and sperm function. MATERIAL ANDMETHODS:
Prospective study over 26months of 143 patients referred to the service for infertility assessment of the couple. Demographic data, primary or secondary character of infertility, risk factors (tobacco, inguinal hernia, varicocele and history of urogenital infections), semen parameters (volume, mobility, pH, vitality and morphological abnormalities) were studied as well as the determination of the anti-C. trachomatis IgG titer. The prevalence of Chlamydia infection and the association of the infection and alteration of the various parameters of the semen were analyzed.RESULTS:
The average age of patients was 38.5±8.55. Infertility was primary in 72% of patients. Among the patients, 54.5% had an abnormal spermogram. Chlamydia IgG antibodies were positive in 37.1% of patients whose 58.5% had abnormal spermogram. Analysis of sperm parameters of patients with and without IgG C. trachomatis showed an altered vitality in Chlamydia positive patients with an OR at 2.41, P=0.02, (95% CI 1.15-5.06).CONCLUSION:
The prevalence of Chlamydia infection is high in infertile male. C. trachomatis IgG antibodies may be associated with an alteration of spermatozoa vitality without significant impairment of other semen parameters. LEVEL OF EVIDENCE 3.Palavras-chave
