Pornography Abstinence and Nocturnal Erections in Adult Men

The effects of pornography use on male sexual health remain uncertain, with mixed findings across existing literature and substantial variability at the individual level. This observational study is designed to help participants evaluate how a 30-day period of pornography abstinence affects their own sexual health and well-being, with a specific focus on nocturnal penile tumescence as a physiological biomarker. Participants will complete a short baseline observation period during which they maintain their usual pornography consumption patterns, followed by a 30-day abstinence period. Objective nocturnal erection data will be collected using a connected wearable device, alongside validated self-report questionnaires assessing erectile function, sexual desire, mood, energy, and emotional well-being. Participants serve as their own control, allowing for within-person comparisons of outcomes before and during the abstinence period.

Effect of Propofol vs. Sevoflurane on Erections During Narcosis In Transurethral Surgery

Penile erection is an unwanted event in transurethral (through the urethra) surgeries, which may be associated with adverse outcomes such as impaired access, prolonged operation time, the need to abort the operation, or the necessity for ancillary measures to achieve penile flaccidity, such as the injection of certain medications directly into the penis. To reduce greenhouse gas emissions, the primary use of propofol instead of gaseous agents is being recommended for general anesthesia. Whether propofol may be associated with an increased or decreased rate of unwanted intraoperative penile erection compared to other anesthetic agents is not known. More generally, there are no high-quality studies available to evaluate the impact of the type of general anesthesia on the risk of unwanted penile erections during surgery. This study aims to determine whether general anesthesia with propofol is more likely to cause intraoperative erections compared to sevoflurane during transurethral operations.
