Gynecomastia surgery in Seoul
Lose the chest.
Lose the chest.
Keep the confidence.
Gynecomastia is enlarged male breast tissue caused by hormones, weight, medication or steroids. Diet and gym won't remove glandular tissue — surgery does. Our urologists grade every chest by ultrasound before planning gland removal, liposuction, or both.

Quick answers
Men's urology in Seoul — the facts
Where is HIGHST Urology?

What is 5S penile enlargement?

FAQ
Straight answers.
How long do I need to stay in Seoul for penile enlargement surgery?
Most international patients plan a stay of about one week so the surgeon can check healing before departure. The exact timeline depends on which 5S components you choose — your surgeon confirms it during the online consultation. Follow-up continues remotely for 12 months.
Is penile enlargement surgery in Korea safe?
Safety depends on the surgeon and the materials. At HIGHST, surgery is performed by board-certified urologists using certified allograft dermis with authenticity documents, after 5-stage pre-operative testing, with OR CCTV available on request. Like any surgery, there are risks (swelling, infection, asymmetry), which your doctor explains before consent.
What causes gynecomastia, and will exercise fix it?
Gynecomastia is caused by hormonal imbalance, weight gain, certain medications, steroid use, or liver/kidney conditions. Exercise can reduce fat, but it cannot remove glandular breast tissue. Surgery removes the gland (and fat if needed) through a 5 mm armpit incision in about 40–60 minutes.
How soon after exposure should I get an STD test?
Most STDs have a window period of about 2 days to 1 month. If you have symptoms such as discharge, burning or itching, come in right away. Without symptoms, your urologist will recommend the best test date and a retest schedule. See our STD testing page.
Is my visit confidential? Do I need Korean insurance?
Yes, every visit is confidential, and you do not need Korean national health insurance — foreign patients can pay directly. Results are shared only with you, by private message or in person.
Do the doctors speak English?
Consultations are available in English with dedicated international coordinators via WhatsApp and KakaoTalk, so you can ask questions before you book a flight.
How much does penile enlargement or gynecomastia surgery cost in Korea?
Cost depends on your anatomy and which procedures you combine. Send a WhatsApp message for a doctor-reviewed, itemized quote — no obligation.
