>While erect lengths are consistent, erect lengths measurements can also create challenges. Different techniques have been described to measure the erect length including self-report, in office spontaneous erection, and in-office intracavernosal (i.e., penile) injection. Because of their inherent biases, self-reported lengths should be regarded with caution. Studies attempting to analyze spontaneous erections in the clinic, on the other hand, have omitted numerous individuals who were unable to “perform” in this unnatural scenario [39]. The simplest technique to achieve an erection is penile injections which are routinely utilized to generate an erection in clinical settings [21, 37, 90].
