阴茎体积描记仪
有膨胀问题的男子，也就是说勃起困难的男子，应该进行一个特殊的夜间检测，以排除生理方面的病因。一个健康男子在睡眠期的规律性复现的所谓快速动眼睡眠期(rapid-eye-movement phase, REM)会有阴茎勃起。显然，对夜间具有这种无意识的阴茎勃起的男子，可以排除生理方面的病因。因为在夜间的测试中，这个男子住进了睡眠测验室，他的阴茎套连着所谓的阴茎体积描记仪(penile plethydmograph)，通过这个描记仪，记录了睡眠期间的阴茎膨胀增加和消退的程度。第二天早晨，可以在描记图上读取记录结果。如果显示了预期的勃起记录，说明无生理方面的病因；如果未显示勃起或出现非常微弱的勃起，可能有某些血管方面的病症，则需要进一步的检查和治疗。

Sexological Examination - In Men

The Penile Plethysmograph
Men who have tumescence problems, i.e. erection difficulties, should undergo a special overnight test in order to rule out physical causes. Healthy men have erections in their sleep during the regularly recurring so-called REM (Rapid-Eye-Movement) phase. Obviously, in men who have these unconscious nightly erections a physical cause can be ruled out. For the overnight test, the man checks into a sleep lab. Before he goes to sleep, a  so-called penile plethydmograph is attached to his penis where it records the increasing and decreasing degrees of tumescence during sleep. The next morning, the test results can be seen in a recording chart. If it shows the expected erections, there is no physical problem. If it shows no or very weak erections, there may be some vascular problem needing further investigation and treatment.
