Introduction

There is no absolute fixed age for circumcision. The preferred time for surgery is during childhood, particularly the school-age period. However, adults diagnosed with phimosis can undergo surgery at any time, with the decision based on a comprehensive assessment of the type of phimosis and the individual’s physical development. If recurrent inflammation of the genital area or difficulty urinating occurs, prompt medical evaluation for possible surgical intervention is recommended. Physiological phimosis is commonly observed in infants and young children and is considered a normal part of development.

There is no universally fixed optimal age for phimosis surgery. The preschool to school-age period in childhood is generally considered the preferred time for surgical intervention; however, surgery can also be performed at any time after diagnosis in adulthood. The decision should be made comprehensively, taking into account the specific type of phimosis and the individual’s physical development. If recurrent inflammation of the genital area or difficulty urinating occurs, prompt medical evaluation and surgical assessment are recommended.

Physiological phimosis is common in infants and young children and represents a normal developmental phenomenon—early intervention is unnecessary. As the child grows, the foreskin gradually retracts naturally, and the glans penis becomes progressively exposed. In school-age children with persistent true (pathological) phimosis—characterized by a narrow preputial opening that prevents retraction—surgical correction may be indicated. Timely surgery helps prevent accumulation of smegma and local inflammation, and avoids adverse effects on normal development of the external genitalia.

In adults diagnosed with phimosis, surgical treatment is recommended regardless of symptom duration. Adult phimosis does not resolve spontaneously; prolonged untreated phimosis increases the risk of balanoposthitis, urinary dysfunction, and may negatively impact post-marital quality of life. Clinically, circumcision is the primary surgical procedure used to correct this condition. It involves minimal tissue trauma and offers rapid recovery, effectively resolving the various health risks associated with phimosis.

Maintain daily hygiene and care of the external genitalia: gently cleanse exposed areas with warm water, keep the area dry and well-ventilated, cultivate good personal hygiene habits, minimize smegma accumulation, and thereby sustain optimal genital health.

What Should You Pay Attention to When Undergoing Circumcision?

Circumcision requires attention to several key aspects, including preoperative examinations and preparations, preoperative lifestyle adjustments, postoperative wound protection, postoperative medication management, and follow-up visits. Properly managing each of these steps helps minimize complications and supports smooth wound healing; prompt medical consultation is essential if signs of bleeding or infection worsen. 1. Preoperative Examinations and Preparations: Complete the required baseline tests prior to surgery to assess the patient’s actual physical condition.

Painless circumcision procedure

In general, painless circumcision refers to a surgical procedure performed after administering anesthesia to ensure the patient feels no pain throughout the operation. The doctor first performs preoperative disinfection. The patient is placed in the lithotomy position and receives sacral canal anesthesia. Once the anesthesia takes effect, the genital area is disinfected and draped. The surgeon uses the index finger of the right hand to dilate the anus until it can accommodate four fingers, then inserts a speculum.
