The relationship between sexually transmitted microorganisms and seminal quality in asymptomatic men.

ABSTRACT:

Objective

To detect DNA of different microorganisms, in semen samples from apparently healthy men and correlate their presence with seminal quality.

Methods

Semen samples from 81 healthy volunteers were collected, and semen parameters were analyzed. DNA extraction was performed using the phenol-chloroform technique, and the microorganisms were detected by the amplification of specific primers using polymerase chain reaction.

Results

DNA from at least one of the microorganisms was detected in 78 samples. The most frequent microorganism found in semen were: Lactobacillus spp. (70%), Neisseria gonorrhoeae (N. gonorrhoeae) (36%), Streptococcus epidermidis (64%), Klebsiella pneumoniae (56%), Staphylococcus aureus (32%), Chlamydia trachomatis (C. trachomatis) (28%), Pseudomonas aeruginosa (27%). The seminal parameters of all semen samples were over the lower reference values for normal semen analysis. To compare with negative samples, seminal volume was higher for the Escherichia coli positive samples and lower for Pseudomonas aeruginosa positive samples. Semen samples positive for Staphylococcus aureus had worse sperm morphology. The frequency of progressive motility was higher in positive samples for N. gonorrhoeae and C. trachomatis. Positive semen samples for C. trachomatis had a higher concentration per milliliter.

Conclusion

It is common to find microorganisms in semen of asymptomatic men, including those responsible for sexually transmitted infections. Antimicrobial treatment is recommended only in those individuals with a sexually transmitted infection (C. trachomatis and N. gonorrhoeae) and always promote condom use.

Project description:BackgroundHigh rates of sexually transmitted infections (STIs) among men who have sex with men (MSM) have been reported, but there is little research on their STI knowledge. Our study sought to determine participants' characteristics that contribute to either high or low STI knowledge among MSM in Nairobi, Kenya.MethodsWe mobilized MSM aged ≥18 years from Nairobi into a cross-sectional study. To determine their understanding of STIs, a pre-tested structured questionnaire was administered. Knowledge score was generated by summing up the number of responses answered correctly by a participant. We dichotomized scores as "low" and "high", by splitting the group at <12 and ≥12 which was the mean.ResultsA total of 404 participants were interviewed between March and August 2020. The mean age was 25.2 (SD = 6.4) years. Majority were single (80.4%) and Christians (84.2%). All participants had some formal education ranging from primary to tertiary; the majority (92.3%) had secondary education or more. Most (64.0%) were employed and their monthly income ranged from <50->150 USD. Almost all (98.5%) were Kenyans. Of the 404 (90.6%) self-identified as male and (47.5%) reported to be exclusively top partners. Many (39.9%) reported being versatile, while those reporting to be bottom partners were, (12.6%). The last 12 months, (55.4%) of the participants reported having sex with men only and (88.6%) reported to have had multiple sexual partners. Participants scored an average of 12.2, SD 4.5. Multivariable backward elimination logistic regression revealed that participants who had tertiary education (aOR = 0.50, 95% CI 0.32-0.77), a higher income (aOR = 0.40, 95% CI 0.22-0.75) and were engaging in vaginal sex (aOR = 1.86, 95% CI 1.25-2.78) predicted significantly higher odds of high knowledge in the final multivariable model.ConclusionParticipant's knowledge level regarding STIs was low. We recommend health care workers to continue educating patients about STIs.
