JAKARTA - In some men, penis erection in the morning is a common thing. This condition is not an abnormality, but a normal thing experienced by men.

This was conveyed by an urologist, Dr. Reena Malik. He said that an erection in the morning has become normal from a man's physiological.

"It's just because you have erotic dreams or thoughts about sex, an erection in the morning is normal in men's physiology," said Doctor Reena, quoted from her YouTube account Reena Malik, MD, on Thursday, October 30, 2025.

In general, an erection occurs when a man gets sexual nuances, such as watching erotic films, reading books or adult novels, or having sex with a partner.

However, penises that have an erection in the morning are usually not only caused by these factors. Penis that have an erection in the morning may occur due to the soaring hormone levels.

The hormone testosterone is a hromon that plays a role in sperm and manifold production. These hormones affect the level of male libido. By increasing the hormone testosterone in the morning, even without receiving a ring, the penis can have an erection.

In addition, an erection in the morning can also be associated with a rapid eye movement (REM) during sleep. When sleeping, the nervous system will test the body's function by providing rangans on various parts of the body, including penises.

Therefore, during REM, brain activity increased, the parasimpathic nervous system became more active, and nerves that inhibited the erection became less active, helping the penis harden in the morning.

Thus, men should not feel afraid or strange if they have an erection in the morning even without a ring. Erections in the morning (noctural penis/NPT) can be a sign of a normal and healthy penis.
