Nocturnal emission, commonly known as “nightfall” or “wet dream,” is a natural and involuntary occurrence that happens during sleep. It is characterized by the release of semen from the penis during ejaculation while dreaming, typically associated with sexual content. Nightfall is a normal physiological process that often begins during adolescence and continues into adulthood.

Nightfall occurs due to the buildup of semen in the reproductive system, and it serves as a mechanism to release excess semen. It is a natural way for the body to regulate and maintain reproductive health. While nightfall is considered a normal part of sexual development, excessive or frequent occurrences may indicate underlying factors that warrant attention.

Several factors are responsible that causes Night fall. Some of them are: 

1. Hormonal changes during puberty.
2. Sexual arousal and fantasies during sleep.
3. Sexual abstinence or suppression of desires.
4. Psychological factors like stress and anxiety.

Diagnosis of Nightfall:

1. Evaluation of medical history and sexual development.
2. Discussion of frequency and impact on daily life.
3. Psychological assessment to address underlying issues.
4. Rule out any medical conditions or hormonal imbalances.
