Nocturnal Erections

Younger men generally have more frequent and stronger nighttime erections. Nighttime erections generally decrease as men age. Nocturnal erections are spontaneous erections that occur during sleep. The optimal target is approximately 3 hours and 30 minutes of nocturnal penile tumescence per night. The current baseline averages 2 hours and 12 minutes of erection time per night. The observed effect appeared to reverse or amplify a function that normally declines with age. Nocturnal erections are presented as a meaningful biological age marker. Nocturnal penile tumescence serves as a marker for sexual health and biological aging.
