Brief summary
The Feeling Hot studies focus on the proof-of-principle of using temperature sensing as a tool to detect nocturnal erections. In the Feeling Hot 1 study the influence of environmental factors of overnight measurements are studied in a controlled setting. Healthy individuals will have visually aroused erections in different circumstances (naked, clothing, blankets) to determine the feasibility of this new measurement method for nocturnal erection detection in the search to modernize erectile dysfunction diagnostics.
Detailed description
Differentiation in nature of erectile dysfunction (ED) is currently made by nocturnal erection detection with the RigiScan. The RigiScan uses outdated software, measurements are user unfriendly and system components are out of stock. In the search of modernizing erectile dysfunctions diagnostics, the question has arisen whether temperature measurements can function as a tool for nocturnal erection detection. With the absence of a pressure component, the patient experience should improve. Literature and mathematical modelling studies have shown that the penile temperature increases significantly during erection. However, it is unclear what the influence of environmental factors such as blankets and clothing is on the increase in penile temperature during erection. The Feeling Hot 1 study explores the effects of these environmental factors in a controlled setting to gain insight into the possibility of using temperature sensing to detect nocturnal erections.
Interventions
The Feeling Hot sensor system consists of two temperature probes placed on the penis and outer thigh of the test subject to measure skin temperature during erection.
