Abstrakt: Background: Chlamydia trachomatis is considered a public health problem due to the high prevalence in sexually active women and men. The distribution of genital Chlamydia genotypes among Mexican men is unknown.
Objective: To assess the prevalence of Chlamydia genotypes in men with infertile women as sexual partners.
Methods: A total of 659 urine samples were collected from men whose sexual partners were infertile women; the identifying Chlamydia infection was by means of a real-time nucleic acid amplification test (qPCR). OmpA gene PCR-RFLP and sequencing were used to confirm the genotypes of C. trachomatis. The association of genotypes with age, spermatic parameters and gynecological data of sexual partners was further analyzed.
Results: Forty-nine urine samples were positive infection (7.4%). The Chlamydia infection was significantly associated with teratozoospermia, azoospermia, hypospermia, and oligozoospermia. Five genotypes (F 51%; 12.2% to D; 12.2% to E; 6.1% to L2 and 4.1% Ia) were correctly identified. None genotypes identified in this comparative study were positively associated with changes in some of the spermatic values because all of them typically produce some considerable damage to these cells.
Conclusions: The F genotype was the most frequent genotype identified in infertile men from Mexico City and all genotypes play an important role in the seminal alteration of Mexican men whose female partners are infertile.
