Vaseline self-injection into the penis is currently a popular procedure in prisons. Since such injections are illegal, severe complications of the procedure can often remain hidden.
To identify the incidence, motivation, and morbidity of Vaseline self-injection into the penis among inmates.
A total of 4,735 inmates at the largest Hungarian prisons were asked to complete a questionnaire relating to their sexual life, whether they had self-injected Vaseline into their penis, the motivation leading them to resort to Vaseline self-injection, any complications observed and the level of satisfaction attained.
A 17-point questionnaire on the circumstances, motivations, and complications of Vaseline self-injection among prisoners.
Of the 1,905 responders, 15.7% admitted Vaseline self-injection. Only around one-fifth of the Vaseline injected subjects had not been satisfied with the original size of their penis and their sexual life up to the time of the injection, a proportion similar to that among Vaseline nonusers. While the satisfaction with the sexual life became significantly worse after the Vaseline injection, the satisfaction with the penis size did not change and an erectile dysfunction developed de novo in 21.4% of cases. The most common motivation for self-injection was a recommendation by another inmate; it was rarely recommended by a sexual partner. Complications had developed among 25.4% of the Vaseline users and 50.3% of them were not satisfied with the result of the Vaseline injection. Of the Vaseline users, 22.4% regretted the self-injection, while the rate among those who had developed complications was 53%.
The self-injection of Vaseline into the penile skin proved to be somewhat of a trend among these inmates. The complications depended mainly on the amount of Vaseline injected, the poor hygienic circumstances, and the personal tolerability. Increased awareness is needed for the prevention of this social, psychological, and physical problem.
凡士林自注阴茎在监狱中目前是一种流行的程序。由于这种注射是非法的，该程序的严重并发症往往仍然隐藏。
确定凡士林自注阴茎在囚犯中的发生率、动机和发病率。
共 4735 名囚犯在匈牙利最大的监狱被要求完成一份与他们的性生活有关的问卷，他们是否曾将凡士林自行注入阴茎，导致他们诉诸凡士林自我注射的动机，观察到的任何并发症以及达到的满意度。
囚犯中凡士林自我注射的情况、动机和并发症的 17 点问卷。
在 1905 名应答者中，15.7%承认凡士林自注。只有大约五分之一的凡士林注射者对阴茎的原始大小和注射前的性生活不满意，这一比例与凡士林非使用者相似。虽然凡士林注射后性生活满意度显著下降，但阴茎大小的满意度没有改变，21.4%的病例新出现勃起功能障碍。自我注射的最常见动机是另一名囚犯的推荐；它很少是由性伴侣推荐的。25.4%的凡士林使用者出现并发症，其中 50.3%对凡士林注射的结果不满意。在凡士林使用者中，22.4%后悔自我注射，而出现并发症的人中这一比例为 53%。
凡士林自注阴茎在这些囚犯中已经成为一种趋势。并发症主要取决于凡士林的注射量、卫生条件差和个人耐受性。需要提高对这种社会、心理和身体问题的认识，以预防这种问题。
