In 1953, sex researcher Alfred Kinsey found that nearly 40% of the women he interviewed have had one or more nocturnal orgasms or wet dreams. The study indicates that such a first ejaculation resulting from a nocturnal emission was delayed a year or more from what would have been developmentally possible for such males through physical stimulation. Kinsey found that males experiencing their first ejaculation through a nocturnal emission were older than those experiencing their first ejaculation by means of masturbation. Thirteen percent of males experience their first ejaculation as a result of a nocturnal emission. In a 1998 study by Finkelstein et al, the number of boys reporting nocturnal emissions drastically increased as their testosterone doses were increased, from 17% of subjects with no treatment to 90% of subjects at a high dose. One factor that can affect the number of nocturnal emissions males have is whether they take testosterone-based drugs. In general the males who have the highest frequencies of nocturnal emissions may have somewhat lower rates of masturbation." ".some correlation between the frequencies of masturbation and the frequencies of nocturnal emissions. The frequency with which one has nocturnal emissions has not been conclusively linked to frequency of masturbation. Some males have the emissions only at a specific age, while others have them throughout their lives following puberty. For example, in Indonesia surveys have shown that 97% of men experience nocturnal emissions by the age of 24. In some parts of the world, nocturnal emissions are more common. For married males, the mean ranges from 0.23 times per week (about once per month) for 19-year-old married males to 0.15 times per week (about once every two months) for 50-year-old married males. įor males who have experienced nocturnal emissions, the mean frequency ranges from 0.36 times per week (about once every three weeks) for single 15-year-old males to 0.18 times per week (about once every five-and-a-half weeks) for 40-year-old single males. In the U.S., 83% of men experience nocturnal emissions at some time in their life. Some males have experienced large numbers of nocturnal emissions as teenagers, while others have never experienced any. Some reported that it is due to being sexually inactive for a period of 1–2 weeks, with no engagement in either intercourse or masturbation. The frequency of nocturnal emissions is highly variable. 4% of sex dreams among both men and women resulted in orgasms. In a detailed study, men and women reported that roughly 8% of their everyday dreams contain some form of sexual-related activity. In the largest study, which included nocturnal emission samples from 10 men with idiopathic anejaculation, the semen concentration was equivalent to samples obtained from the same men by penile vibratory stimulation, although the proportions of sperm which were motile and which were of normal morphology were higher in the nocturnal emission specimens. Composition ĭue to the difficulty in collecting ejaculate produced during nocturnal emissions, relatively few studies have examined its composition. Vaginal lubrication alone does not mean that the woman has had an orgasm. It is possible for men to wake up during a wet dream or simply to sleep through it, but for women, some researchers have added the requirement that she should also awaken during the orgasm and perceive that the orgasm happened before it counts as a wet dream. Nocturnal emissions can start as early as age nine and are most common during adolescence and early young adult years, but they may happen any time after puberty. Nocturnal emissions happen after stressful dreams in REM sleep which activate the sympathetic nervous system hence leading to ejaculation. For other uses, see Wet dream (disambiguation).Ī nocturnal emission, also known as a wet dream, sex dream, nightfall, or sleep orgasm, is a spontaneous orgasm during sleep that includes ejaculation for a male, or vaginal lubrication and/or an orgasm for a female.
