Abstract

Introduction
Penile constriction devices are a noninvasive way to improve sexual performance and erectile function, making them an appealing choice for men. To understand their clinical value and patient satisfaction, it is important to assess patient preferences and the efficacy of different devices. Comparative studies between heterosexual and homosexual men are also necessary to recognize and meet the diverse needs and experiences of these populations, leading to more tailored and effective recommendations.

Objective
To assess and compare the preference and effectiveness of two medical-grade penile constriction devices.

Methods
Between May 2023 and July 2023, males were recruited via social media platforms and prospectively enrolled into an IRB-approved, randomized, questionnaire-based study. Upon enrollment, the participants completed the Sexual Health Inventory for Men (SHIM) and Androgen Deficiency in Aging Males (ADAM). Participants were then randomized to which device (FirmTech vs Eddie by Giddy) they would receive first and were instructed to use the device twice either during masturbation or intercourse within a two-week timeframe. Once utilized, the participants completed a 17-question, five-point Likert scale device satisfaction questionnaire. Once the first device and survey were completed, the other device was sent and the process was repeated. In the device satisfaction questionnaire, lower numbers indicated more positive responses to the questions. Responses from the questionnaire with numerical values are presented as the mean difference (MD) and analyzed using a paired t-test. Questionnaire responses that were “yes” or “no” were analyzed using McNemar’s chi-square analysis. A p-value less than 0.05 was considered significant.

Results
Fifty men were enrolled and 44 completed the study. Among the participants, 31 (70.4%) identified as homosexual, 10 (22.7%) as heterosexual, and 3 (6.8%) as bisexual with a mean age of 36.5 (IQR = 16.5). Table 1 provides a summary of the demographic characteristics. The baseline mean SHIM and ADAM score was 19.5 and 0.5, respectively. A statistically significant preference for the ease of putting on the FirmTech device while erect was found (MD,-0.84; p = 0.001). There was also a statistically significant preference for the comfort, adjustability, and stretch of the FirmTech device (MDs -0.66, -0.32, and -0.86; respective p values 0.018, 0.033, and &lt;0.001). Finally, 35 (79.5%) participants stated that they would recommend FirmTech to a friend, as opposed to 25 (55.6%) who would recommend Eddie by Giddy (p = 0.020).

Conclusions
These findings suggest that, when comparing penile constriction devices, men prefer the FirmTech device over the Eddie by Giddy with respect to ease of putting on the device, comfort, stretch, and adjustability. Men are more likely to recommend the FirmTech device over Eddie by Giddy. Further research with a larger sample size, which includes a more equal distribution of men of different sexual orientations, is warranted to further support the generalizability and validity of these initial findings, illustrate consumer preference for FirmTech, and expound upon its preferential qualities.
