Introduction
Penile impairment: Phimosis can restrict the glans penis, impairing its normal development and potentially resulting in a significantly reduced coronal circumference, thereby affecting sexual intercourse. Infection: Phimosis predisposes to accumulation of smegma; improper hygiene may lead to secondary inflammatory conditions, such as prostatitis or orchitis.

Some men experience phimosis (excessively long foreskin). If left untreated, it may adversely affect health—including penile injury, premature ejaculation, infections, and infertility.

① Penile Injury

With phimosis, the foreskin and glans penis are prone to adhesion. Since the glans remains enclosed within the foreskin, it may become constricted, impairing normal glans development. In severe cases, the coronal circumference of the glans may be significantly reduced, thereby interfering with sexual intercourse.

② Premature Ejaculation

In cases of phimosis, the glans remains constantly covered by the foreskin, resulting in reduced tactile stimulation and friction. Consequently, during sexual intercourse, the glans becomes hypersensitive, potentially triggering premature ejaculation.

③ Infections

Phimosis creates a warm, moist environment conducive to bacterial growth and proliferation. Over time, this may lead to accumulation of smegma (foreskin debris), predisposing individuals to balanoposthitis or urinary tract infections. Improper management may further precipitate other inflammatory conditions, such as prostatitis or orchitis.

④ Infertility

Phimosis may compromise male fertility. Failure to maintain adequate hygiene or delay in undergoing circumcision allows smegma accumulation, which can contribute to prostatitis—thereby impairing sperm motility and altering seminal viscosity—ultimately leading to infertility.
