About this study
Official title: Feeling Hot 1: Investigating the Influence of Clothing and Blankets on Penile Skin Temperature During Male Sexual Arousal
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.
Read the 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 The RigiScan uses outdated software, measurements are user unfriendly and system components are out of stock.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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Feeling Hot sensor systemDevice
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.
| Study group | Role | What they receive |
|---|---|---|
| Visually aroused erection (naked, clothing, blankets) | Other | Randomisation of the order of visually aroused erection will be conducted:
1. Naked - Naked \& Blanket - Clothing \& Blanket
2. Naked - Clothing \& Blanket - Naked \& Blanket
3. Naked \& Blanket - Naked - Clothing \& Blanket
4. Naked \& Blanket - Clothing \& Blanket - Naked
5. Clothing \& Blanket - Naked - Naked \& Blanket
6. Clothing \& Blanket - Naked \& Blanket - Naked Receives: Device: Feeling Hot sensor system |

Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Temperature increase (time frame: 10 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2022.
