Seropositivity of <i>Chlamydia trachomatis & Toxoplasma gondii</i> among male partners of infertile couples in Odisha, India: A facility-based exploratory study
Naik et al.
The finding, in our words
The study found comparable seropositivity for Chlamydia trachomatis and Toxoplasma gondii among male partners of infertile couples in Odisha, with 28 per cent showing anti-Chlamydia IgA and 28 per cent anti-Toxoplasma IgM antibodies. This demonstrates that first-void urine and seminal fluid can detect relevant infections, supporting their use in decentralised fertility screening programmes.

In 250 Iranian infertile couples followed for 24 months, detection of Chlamydia trachomatis DNA in first-void urine, semen or serum antibodies did not predict tubal factor infertility, pregnancy rate or outcome. This indicates that patient-collected first-void urine screening for these organisms may have limited clinical utility in fertility assessment.

The study of 250 infertile men found that Chlamydia trachomatis infection detected in first-void urine by PCR was associated with lower semen volume, while seminal interleukin levels showed non-significant elevation. This supports the use of patient-centric first-void urine and blood samples for screening sexually transmitted infections in decentralised fertility diagnostics.

A cross-sectional survey of 1,087 men who have sex with men in Jiangsu province, China found a syphilis prevalence of 6.3% and chlamydia prevalence of 4.2%, with higher odds among those recruited online and with recent STI diagnosis. The use of first-void urine for nucleic acid amplification testing demonstrates the utility of decentralised sampling for STI screening in high-risk populations.
Among 250 infertile Iranian men, self-collected first-void urine enabled decentralised detection of Chlamydia trachomatis, yet infection status showed no correlation with sperm chromatin condensation or DNA fragmentation. The study validates first-void urine for remote STI screening in fertility assessment, while indicating sperm quality markers are independent of Chlamydia infection.

The study found that IgG seropositivity against Chlamydia trachomatis was significantly higher in infertile women than in pregnant controls (15% versus 0%), but PCR positivity in first-void urine was very low, with only one of 80 samples positive across all three primer sets. The authors concluded that serological screening is more diagnostically useful than first-void urine PCR for identifying chlamydial infection in infertile women in this setting.
