The goal of this study is to determine whether erectile function is differentially impacted by a single plant-based meat meal versus a single animal meat meal in healthy men with normal erectile function.
Subject provides written informed consent and HIPAA authorization in English before any study procedures are conducted. (If the subject is a fluent Spanish and/or other language speaker, subject must also be fluent in English (understanding and speaking) to be eligible for this study.)

Crossover
Animal-based meal
Other interventionConsuming a single plant-based meat or a single animal meat meal and measuring the meals impact on erectile function with the Rigiscan™ device.

Percent of time with ≥70% erection during overnight sleep after 1 meal
Total time (in minutes) when penile rigidity is ≥70% at both the tip and the base of the penis as measured by Rigiscan™ during overnight sleep, divided by the total time (in minutes) of overnight sleep. Overnight sleep is defined as the time in minutes from the onset of the first nocturnal erection to the end of the last nocturnal erection (as measured by Rigiscan™).
Erection events per hour during overnight sleep after 1 meal
Total number of erection events lasting ≥5 minutes and with ≥70% rigidity at both the tip and the base of the penis as measured by Rigiscan™ during overnight sleep. Overnight sleep is defined as the time in minutes from the onset of the first nocturnal erection to the end of the last nocturnal erection (as measured by Rigiscan™). This result will be reported as Erection Events/hour.
Tumescence events per hour during overnight sleep after 1 meal.
Total number of tumescence events lasting ≥5 minutes and when penile circumference increases by ≥2cm at both the tip and the base of the penis compared to their respective baselines as measured by Rigiscan™ during overnight sleep, divided by the total time (in minutes) of overnight sleep. Overnight sleep is defined as the time in minutes from the onset of the first nocturnal erection to the end of the last nocturnal erection (as measured by Rigiscan™). This result will be reported as Tumescence events/hour.
Heart rate
Comparing heart rate by dietary pattern at both time points after overnight sleep after consuming the 1 meal and compared to its respective baseline in beats/minute.
Blood pressure
Comparing blood pressure (both systolic and diastolic) by dietary pattern at both time points after overnight sleep after consuming the 1 meal and compared to its respective baseline in mmHg.
