Is it necessary for a 30-year-old to undergo circumcision surgery?
Generally speaking, whether circumcision surgery is needed at the age of 30 depends on whether obvious symptoms are present. If there is no discomfort, surgery may be postponed. However, if there are issues such as recurrent infections, surgery is recommended. If in doubt, it is advisable to seek medical consultation in advance. Detailed explanation is as follows:

If the foreskin can be easily retracted, daily hygiene is manageable, and there are no abnormalities in urination or inflammation infections, surgery is usually unnecessary. These situations typically have no significant impact on daily life, and maintaining genital hygiene suffices to preserve reproductive health without excessive concern.
If the foreskin opening is narrow and cannot be retracted, or if recurrent balanitis, balanoposthitis, difficulty urinating, or discomfort during sexual activity occur, surgery becomes necessary. Without treatment, these conditions may lead to repeated and worsening infections, affecting quality of life. Timely surgery can effectively alleviate symptoms.
The decision to undergo surgery should be based on individual circumstances. It is recommended to visit a reputable hospital for an examination and have a doctor assess your condition before making a decision, avoiding hasty choices or delaying treatment.
