Will the penis become shorter after circumcision?

Some men consider undergoing circumcision but worry whether the procedure will make their penis appear shorter. In fact, some men even report perceiving a reduction in penile length after circumcision. So, can individuals with nephritis take tonics? Let’s explore this further.

Will the penis become shorter after circumcision?

No, circumcision does not shorten the penis. Penile length is determined by the size of the corpora cavernosa—not by the length of the foreskin—so removing excess foreskin has no effect on overall penile length.

Apparent shortening may result from obesity: excessive subcutaneous fat, particularly in the perineal region, can partially conceal the penis, making it appear shorter; weight loss often restores its visible length. Alternatively, frequent masturbation may contribute to perceived shortening due to impaired erectile function—resulting in inadequate penile engorgement compared to previous baseline states.

Circumcision (i.e., surgical foreskin removal) involves excising redundant foreskin to expose the glans penis. It is commonly performed to treat phimosis or redundant prepuce, and to prevent complications such as balanoposthitis. The procedure typically lasts 10–30 minutes, usually requires no hospitalization, and carries minimal surgical risk.

Prior to circumcision, proper local hygiene is essential. Starting three days before surgery, patients should cleanse the genital area daily using warm water or a 1:5,000 potassium permanganate solution. During cleansing, the foreskin should be gently retracted to fully expose the coronal sulcus and thoroughly remove smegma. However, care must be taken to promptly return the foreskin to its normal position afterward to avoid paraphimosis. Additionally, patients are advised to fast for 4–6 hours before surgery to minimize gastrointestinal discomfort.
