Brief Summary
The proposed research aims to 1) measure male participants' urinary levels of EDCs and sperm quality before and after report-back and EDC reduction intervention and assess changes, 2) assess the extent to which MM's program (testing, curriculum, and report-back) alters participant environmental health literacy (EHL), readiness to change (RtC), and product/lifestyle choices, and 3) test the feasibility and acceptability of MM's program to male participants. The primary study subjects are adult men of reproductive age. The study aims to have 60 participants complete the study.

Outcome Measures
Primary Outcomes (4)
Change in Environmental Health Literacy
This surveys assesses EDC-specific environmental health literacy, based on questions in a 5-point Likert scale from 1 (strongly agree) to 5 (strongly disagree) or 1 (never) to 5 (always). Responses will be reverse coded during analysis as needed so that higher numbers reflect positive outcomes (higher EDC-EHL).
12-weeks
Change in Sperm Count
Changes measured from Fellow Sperm Test- total motile count at the baseline and post intervention.
12 Weeks
Change in Readiness to Change
The Readiness to Change question asks participants to choose the response (sentence) that most accurately describes their current efforts and interest in limiting their exposure to harmful chemicals. Responses will be coded from 1 to 5 with 5 reflecting greater readiness to reduce risky behaviors.
12 weeks
Change in Metabolites
Urinary EDC metabolites include bisphenols, phthalates, parabens and oxybenzone.
12 weeks
Secondary Outcomes (9)
Change in Sexual Satisfaction (From the International Index of Erectile Function (IIEF) Survey)

Change in Sexual Health Inventory (SHIM)

Study Arms (2)
Education Intervention
EXPERIMENTALStudy participants receive lifestyle audit and educational intervention program in addition to urine and sperm testing.
Control
NO INTERVENTIONStudy participants receive urine and sperm testing only.

Data will be available for use only to answer the specific question(s) indicated in the research plan. The researchers must provide a list of variable names and an outline of how research findings will be disseminated; and will be asked to sign a data-sharing agreement that commits to: 1) not attempt to identify any individual participant, 2) secure the data using appropriate software technology, 3) and destroy or return all data once analyses are complete. All final datasets will be de-identified. Final authorship on manuscripts will require review and approval by the Principal Investigators of this study.
Million Marker will disseminate research results and findings to the scientific community through presentations at scientific meetings and conferences and publications in academic journals, as well as through the mass media and online postings. The Principal Investigator of this study will make data and associated documentation/metadata available to external researchers under a data-sharing agreement in which a specific commitment is made to use the data for research purposes only, to not provide the data to a third party or distribute it in any form, and to properly acknowledge the source of funding for the collection of the data and the researchers involved in this study.
