Is it true that wet dreams is a signal the boy now producing sperms?

Yes, wet dreams, also known as nocturnal emissions, are an indication that a boy has reached sexual maturity and is now producing sperm. During puberty, the body undergoes several changes, including the production of hormones that stimulate the testes to produce sperm and the growth of the male reproductive organs. As a result, males start experiencing involuntary ejaculation during sleep, known as wet dreams, where seminal fluid containing sperm is released from the penis.

However, it is important to note that having wet dreams does not necessarily mean that a boy is ready for sexual intercourse or has reached full reproductive maturity. Other physical, emotional, and psychological changes also accompany sexual development and must be taken into consideration.
