Exposure to polybrominated diphenyl ethers and male reproductive function in Greenland,Poland and Ukraine

Animal and a few human studies suggest that polybrominated diphenyl ethers (PBDEs) may affect male reproductive function. The aim of the present study was to evaluate if male reproductive function was associated with serum level of PBDEs. We evaluated, in a cross-sectional study, the effects of environmental exposure to BDE-47 and BDE-153 on reproductive hormones and semen quality, including markers of DNA damage and apoptosis, in 299 spouses of pregnant women from Greenland, Poland and Ukraine. Adjusted linear regression models indicated no strong associations between BDE-47 or BDE-153 exposure and markers of male semen quality or reproductive hormones. In the largest study to date we demonstrate that BDE-47 and BDE-153 exposure was not associated with altered semen characteristics or reproductive hormones, indicating that male reproductive function is not affected by the exposure level of these compounds in fertile European or Arctic populations.     

Pyrethroid insecticide exposure and semen quality of young Japanese men

The present study aimed at assessing the relationship between exposure to pyrethroid insecticides and semen quality in 323 university students recruited in a population-based manner in Metropolitan Tokyo. Urinary concentrations of pyrethroid insecticide metabolite, 3-phenoxybenzoic acid (3-PBA), were measured by LC/MS/MS and semen parameters were measured by following internationally harmonized protocols. Median urinary 3-PBA concentration was 0.641 ng/mL (specific gravity-adjusted, n = 322). Median values of semen volume, sperm concentration, motility, total number of sperm, and total number of motile sperm were 2.5 mL, 56 × 10⁶/mL, 61%, 141 × 10⁶, and 82 × 10⁶, respectively. Urinary concentration of 3-PBA was not selected as significant in multiple regression models indicating, in contrast to previous findings, that environmental exposure to pyrethroid insecticides did not affect semen quality. This inconsistency may be related to exposure to different pyrethroid insecticides and/or levels of exposure as well as to survey design (hospital- vs population-based subject recruitment).     

Effect of lubricants and a vaginal spermicide gel on the detection of prostate specific antigen,a biomarker of semen exposure,using a quantitative (Abbott ARCHITECT) assay

Objectives

Little is known about the effects of commonly used lubricants on detection of biomarkers of semen exposure. We investigated the in vitro effect of Gynol®, K-Y Jelly®, Replens®, Astroglide®, Carbopol, and Silicorel on quantitative detection of prostate specific antigen (PSA).

Study Design

A predetermined concentration of each of the gels was added to serially diluted semen samples. Additionally, serial dilutions of each of the gels were added to three different semen dilutions (high, medium, or low). The resulting samples were tested for PSA on the Abbott ARCHITECT System.

Results

When using the Abbott ARCHITECT system, the only products that inhibited PSA detection were Gynol® and Replens®. The inhibition caused by Gynol® was dose-dependent, but that of Replens was dose-independent. K-Y Jelly®-spiked samples had higher PSA values than controls.

Conclusions

Caution is warranted when using the Abbott quantitative assay for PSA detection as a biomarker of semen exposure in settings where Gynol®, Replens® or K-Y Jelly® might also have been used. Neither Astroglide® nor Silicorel inhibited PSA detection. Additional studies evaluating other vaginal products, including microbicides, and their effects on other assays, are needed. In vivo studies will be especially important to optimize PSA detection from clinical samples.

Implications

Researchers should consider the potential for specific lubricants or any vaginal products to affect the particular assay used for semen biomarker detection. The Abbott ARCHITECT’s total PSA assay should not be used with the product Replens. Caution is warranted when using the assay in settings where Gynol or K-Y jelly may have been used.
