TL;DR: Qualitative interviews with 6 of the 11 discordant participants provided possible explanations for their PSA test results, and 5 were prompted by direct discussion of those results.

Abstract: We explored the use of qualitative interviews to discuss discrepancies between two sources of information on unprotected sex: biomarker results and self-reported survey data. The study context was a randomized trial in Kingston, Jamaica examining the effect of STI counseling messages on recent sexual behavior using prostate-specific antigen (PSA) as the primary study outcome. Twenty women were interviewed. Eleven participants were selected because they tested positive for PSA indicating recent semen exposure, yet reported no unprotected sex in a quantitative survey (“discordant”): 5 reported abstinence and 6 reported condom use. Nine participants who also tested positive for PSA but reported unprotected sex in the survey were interviewed for comparison (“concordant”). Qualitative interviews with 6 of the 11 discordant participants provided possible explanations for their PSA test results, and 5 of those were prompted by direct discussion of those results. Rapid PSA testing combined with qualitative interviews provides a novel tool for investigating and complementing self-reported sexual behavior.

The use of biomarkers of semen exposure in sexual and reproductive health studies.
TL;DR: Semen biomarkers are innovative and promising tools to further study and better understand women's reproductive and sexual health and behavior and more research is needed to better understand the strengths, limitations, and optimal performance conditions of specific assays in vivo.

Differences in misreporting of sexual behavior over time: implications for HIV trials.
Maria F. Gallo,Lee Warner,Marcia M. Hobbs,Denise J. Jamieson,Tina Hylton-Kong,Markus J. Steiner +5 more
TL;DR: Comparing participant self-report of recent semen exposure to actual semen exposure measured by prostate-specific antigen in vaginal swabs suggests that the accuracy of reports of sexual behavior may vary over time.
Prevalence and risk factors associated with STIs among women initiating contraceptive implants in Kingston, Jamaica.

TL;DR: Although the prevalence of laboratory-confirmed STIs was high, the immediate initiation of a contraceptive implant was not associated with higher STI prevalence rates over 3 months, and the repeated-measures analysis found that PSA detected women did not have an increased prevalence of any STI.

TL;DR: In this low prevalence population, biological markers on their own revealed that a few adolescents had had sex, but in combination with in-depth interviews they may be useful in identifying risk factors for STIs.

Postcoital detection of a male-specific semen protein: application to the investigation of rape
TL;DR: The assay for p30 offers a more sensitive and specific method of semen detection in rape investigation than the enzyme assay for prostatic acid phosphatase, and is concluded to be a male-specific antigen.

TL;DR: Three immunochromatographic PSA membrane test assays are evaluated by analyzing semen stains stored at room temperature for up to 30 years, post-coital vaginal swabs taken at different time after intercourse, semen-free vaginalSwabs, and various female and male body fluids, including urine to demonstrate that PSA membranes test Assays offer the same sensitivity as ELISA-based tests and provide a rapid approach for the forensic identification of seminal fluid.
