Primary outcomes
Change in International Index of Erectile Function (IIEF) questionnaire
The IIEF is a self-administered questionnaire in which participants will be asked to answer 15 questions relating to erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall sexual satisfaction. Lower scores indicated higher perceived erectile dysfunction
Change in Erection Hardness Score (EHS)
Participants will be required to assess their erection quality by using the EHS. They will be asked to rate the hardness of their erection on a scale of one to four, with four being the maximal score.
Secondary outcomes
Change in the Ageing Male Symptom (AMS) Questionnaire
The Ageing Males' Symptoms scale (AMS) is a self-administered questionnaire that will help assess the symptoms of ageing, often related to androgen decline. As the men in this population are aged between 40 and 75 years, this questionnaire will be used to assess any changes in quality of life.
