Abstract

Background Environment-Protection-Agency Reference Doses (EPA RfDs) for phthalate intakes are based on limited evidence, especially regarding low-dose male-reproductive toxicity. This study investigates the association between phthalate exposure and semen parameters and reproductive hormones in a general population with low phthalate exposure compared to the EPA RfDs. Methods The MARHCS (Male-Reproductive-Health-in-Chongqing-College-Students) cohort recruited 796 male students, who experienced a relocation of campuses and shifting environmental exposure. Urine, semen and blood before and after the relocation was collected and investigated for: (1) the associations between 13 urinary phthalate metabolites and 11 semen/hormone outcomes (five semen parameters including semen volume, sperm concentration, total sperm number, progressive motility, normal morphology) and six serum reproductive hormones including estradiol, follicle-stimulating hormone, luteinizing hormone, prolactin, progesterone, testosterone; (2) re-analysis of the metabolite-outcome associations in the subjects with estimated phthalate intakes below the RfDs; (3) a change in phthalate metabolites and change in semen/hormone outcomes after the relocation; (4) the association between these changes. Results (1) All but two semen/hormone outcomes were associated with at least one phthalate metabolite, e.g., each quartile monoethyl phthalate was associated with a 5.3%, 5.7% and 2.6% decrease of sperm concentration, to…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
