Sperm, Exposure and Endocrine Disruptors (SEED)

Study participants receive lifestyle audit and educational intervention program in addition to urine and sperm testing.

Participants receive a 14 module intervention program about endocrine disrupting chemicals and reducing exposures. Participants must complete at least 8 modules over the course of 8 weeks.

Study participants receive urine and sperm testing only.

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).

Changes measured from Legacy Sperm Test- total motile count at the baseline and post intervention.

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.

Urinary EDC metabolites include bisphenols, phthalates, parabens and oxybenzone.

Measured pre and post intervention to Likert style questions from 1 to 5 on overall self reported sexual satisfaction with higher score indicating more satisfied. Two questions taken from validated survey questions from the international index of erectile function survey including "how satisfied have you been with your overall sex life?" https://www.browardurologycenter.com/pdf/International-Index-of-Erectile-Function-IIEF-Questionnaire.pdf

Validated survey measured pre and post intervention

Add the numbers corresponding to questions 1-5.

TOTAL:

The Sexual Health Inventory for Men further classifies ED severity with the following breakpoints:

1-7 Severe ED 8-11 Moderate ED 12-16 Mild to Moderate ED 17-21 Mild ED

Changes in # of reported product usage including personal care, household, and hair products with more products being worse and less products being better.

SUS is a validated survey measuring the usability of the intervention program at the end of intervention. The score is calculated from 0 to 100 with the greater the score indicating better perceived usability. Scores 60 and greater are considered acceptable.

Change in stress (from validated survey Perceived Stress Scale (PSS-4)). Summarize 4 questions for a score of 0-16. Higher score equals greater stress.

Number of total modules completed/requirements completed

Change in self rated general health ( Behavioral Risk Factor Surveillance System (BRFSS)) "In general my health is" from very good to very bad (coded 1 to 5, 5 being very good). These variables are exploratory and may or may not be included in final analysis.

Change in sleep (BRFSS- Behavioral Risk Factor Surveillance System), including self reported hours of sleep and sleep quality from very good to very bad(coded 1 to 5, 5 being very good). These variables are exploratory and may or may not be included in final analysis.

Change in physical activity (validated survey International Physical Activity Questionnaire (IPAQ)) using calculated MET (Metabolic Equivalent of Task) scores to classify into low, moderate or high physical activity (higher being better).

MET score = (how many days × how many minutes × how hard the activity is), added across all activity types." Walking= 3.3 METs Moderate activity=4.0 METs Vigorous activity=8.0 METs

These variables are exploratory and may or may not be included in final analysis.
