A survey showed that parents underestimate the size of their children’s penis

The Brazilian Society of Urology (SBU) conducted a survey during the Novembrinho Azul Joint Effort, in Florianópolis (SC), to understand how parents and guardians evaluate the development of boys’ reproductive organs.

This initiative took place before the 40th Brazilian Congress of Urology and was motivated by the circulation of videos that incorrectly suggested that children would have a small penis and would need hormonal treatment.

The findings reveal that family perception often differs from clinical norms. Among those interviewed, 48% considered the child’s penis size to be within normal limits, while 24% considered it less than average.

In measurements, experts noted a consistent difference regarding the medical examination performed by caregivers.

Parent’s measurements are up to 3cm less than actual measurement

99 children, accompanied by their guardians, participated in the survey. During the service, each caregiver was instructed to measure the length and diameter of the child’s penis prior to professional evaluation.

The comparison showed the relevant difference. The average measured by the parents was 3.64 cm, while the measurement performed by the urologists was 6.18 cm, a difference of about 2.6 cm.

According to experts, factors such as age, weight and abdominal circumference seem to influence the assessment made by parents, who tend to interpret the organ as smaller in these cases.

Of all the children examined, none of them had a micropenis. The SBU confirms that determining hormonal treatment depends on accurate diagnosis, as the condition is rare and requires objective criteria.

Society also remembers that between the ages of four and the beginning of puberty, the penis is expected to go through a normal period of stable growth.

The research will be published soon and, according to its authors, it reinforces the importance of reliable information to avoid misdiagnoses and unnecessary interventions.
