[Urology] How long does it take for circumcision sutures to fall off?

Following circumcision or other penile surgical procedures, absorbable sutures are commonly used to close the incision site. These sutures are typically made from materials such as polyglycolic acid (PGA), polyglactin 910 (e.g., Vicryl), or chromic gut—designed to gradually break down and be absorbed by the body through hydrolysis or enzymatic degradation. In most cases, visible suture material begins to loosen and slough off within 7 to 14 days postoperatively. Complete absorption usually occurs between 2 to 4 weeks, though individual variation exists depending on factors including suture type, patient age, local tissue perfusion, metabolic rate, and wound healing status.

It is important to note that suture “falling out” does not necessarily indicate full wound healing. The underlying tissue continues to gain tensile strength over several weeks, with maximal collagen maturation occurring around 6 to 8 weeks. Patients should avoid sexual activity, vigorous exercise, and tight-fitting clothing until cleared by their urologist—typically after clinical assessment confirms epithelialization, absence of active inflammation or discharge, and adequate wound integrity.

If sutures persist beyond 4 weeks, become increasingly painful, or are accompanied by signs of infection—including erythema, induration, purulent discharge, or systemic symptoms like fever—prompt urologic evaluation is warranted. Similarly, premature suture loss before day 5–7 may raise concern for wound dehiscence and should be assessed clinically. Routine wound care includes gentle cleansing with mild soap and water, pat-drying, and avoidance of topical antiseptics (e.g., hydrogen peroxide or iodine), which can impair fibroblast function and delay healing.
