Task: Question Answering
Input (English): Passage: Nocturnal emission -- The frequency of nocturnal emissions is highly variable. 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. Some males have experienced large numbers of nocturnal emissions as teenagers, while others have never experienced one. In the U.S., 83% of men experience nocturnal emissions at some time in their life. For 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. 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. In some parts of the world nocturnal emissions are more common. For example, in Indonesia surveys have shown that 97% of men experience nocturnal emissions by the age of 24.
