Explanation:

An Independent variable refers to a variable in a research study that does not depend on the value of other variables in the study. Based on this and the information provided within the question it can be said that the independent variable in this study is the Viagra. Since in this study the main drug that is given to half of the individuals is the Viagra, and it does not depend on any other factor of the study.
