BIG 5
Yezak’s Signature Combination Surgery
The BIG5 combination surgery—which includes penile enlargement, 5 cm length extension, G-spot glans enlargement, Q-Laser premature ejaculation surgery, and erection management—is the procedure that Yezak Urology specializes in and performs with the highest confidence.
When it comes to male surgery, factors beyond size and shape—such as texture, functionality, the condition of the surgical site, and the suitability of surgical materials—must all be carefully evaluated. For more satisfying results, communication between the doctor and patient is essential. Yezak understands this best, which is why the outcomes of their surgeries are especially satisfactory.
With the finest surgical materials, we deliver the best results.
Yezak Derma Plus Penile Enlargement Surgery
Yezak Derma at Yezak Hospital embodies 20 years of expertise and advanced surgical know-how.
By using the most suitable materials for each individual — such as dermal grafts, fillers, or autologous fat — this procedure enlarges the penis by inserting the selected material, resulting in a natural-looking enhancement effect.
Effective lengthening surgery by considering the cause.
5CM Length Extension
Only possible at Yezak!
It has the same lengthening effect as suspensory ligament resection by pulling the penis as far as possible toward the base without resecting the ligament.
Minimizes the risk of recurrence while extending the length by 2~5 cm
(Based on statistical data from 4,000 actual surgical cases)
1. Abdominal fat removal surgery 
2. Scrotal scrotal removal
This surgery pulls out and fixes a buried or hidden penis, typically resulting in an extension of about 2 to 5 cm. It lengthens the penis in its flaccid state before erection, making it an excellent option for those with size-related insecurities. At Yezak, we strive for even greater results through special length and skin plastic surgery options.
The overall balance and aesthetic effect of the genitals are key.
Glans Enlargement Surgery
BEFORE
(For those without fat, it can be replaced with filler)
AFTER
At Yezak, a specialized technique is used to create a tunnel-like space in the glans, which is then filled with filler to achieve enlargement. This method has the advantage of low absorption and minimal side effects.
Because it produces a natural enlargement effect, Yezak performs glans enlargement using filler.
The effect of the Yezak glans enlargement is not only an enlargement of the glans, but also means that one can accurately stimulate sensitive internal spots, maximizing the partner’s sexual satisfaction. Additionally, the injected filler reduces the sensitivity of the glans, helping to delay ejaculation and alleviate premature ejaculation.
Minimal side effects and scarring
Excellent stability and high graft/implant take rate

Q-LASER Premature Ejaculation Surgery

At Yezak, we provide comprehensive premature ejaculation treatment based on our extensive surgical experience and expertise, tailored to each underlying cause. If left untreated, it can lead to decreased sexual desire, depression, and in severe cases, even divorce from one’s partner.

Erectile Dysfunction Treatment
Oral medication 
androgen therapy 
Erectile dysfunction injection therapy [Trimix]
Erectile function requires consistent and timely management. Simply worrying about poor erections without identifying the cause can make it too late. Through 19 diagnostic tests related to erectile strength, the exact cause can be identified and managed. For early-stage erectile dysfunction, doctors prescribe oral medications. If drug treatment is ineffective or contraindicated due to other conditions, testosterone therapy or intracavernosal (injected into the base of the penis) injection therapy (Trimix) may be used.
Erectile dysfunction can arise from various complex causes, and the treatment approach differs for each individual.
General medical examination 
External examination of the penis 
Special Test
Since erectile dysfunction can result from a combination of various factors, precise diagnosis through detailed examinations is essential for effective treatment. At Yezak Hospital, we identify the underlying causes of erectile dysfunction through a range of diagnostic tests and provide personalized, effective treatment plans tailored to each individual.
Specialized Erectile Dysfunction (ED) Test Stages
Rigiscan
A diagnostic test that measures erectile function, including erection strength, rigidity, size, and duration of erection.
Penile Vibratory Threshold Test
A test used to assess the sensitivity of the glans penis and to check for potential abnormalities in the nervous system.
Artificial Erection Induction Test
A diagnostic procedure in which a vasodilator is injected directly into the corpora cavernosa of the penis to induce an erection. This allows evaluation of erectile function, rigidity, size, and vascular response.
Male Hormone Test
A test that evaluates the endocrine system to check for abnormalities in male hormone levels, primarily focusing on testosterone and related hormones.
Surgical materials at Yezak: not just the ‘best’, but the best for you.
Surgical Material Optimization and Selection
At Yezak, we carefully select and use only premium dermal grafts, backed by over 20 years of experience.
In penile enlargement surgery, the most crucial factor is the surgical material. To achieve the desired outcome, it’s essential to choose materials that are medically appropriate, effective, and safe. However, since each dermal graft has distinct characteristics and every patient’s condition is unique, it’s impossible to say that one specific graft is the best for everyone. For better results, a clinic must offer a variety of graft options suitable for individual needs and possess extensive experience in handling different materials. That’s why it’s important to choose a specialized surgeon who has deep expertise in various graft types and can recommend the most suitable option based on each patient’s condition.
Xenograft (Heterologous Dermis)
· Made from ingredients extracted from certain animals
· Excellent enlargement effect and long-lasting
effect compared to the low price
· Low price compared to homologous dermis
YEZAK Derma Plus
This substitute dermis, which embodies 10 years of expertise and technology from Yezak Urology, overcomes all the drawbacks of existing substitute dermis and is exclusively available at Yezak. With a thickness of 4–5 mm, sizes of 5×6cm and 5×8cm, and the advantage of improving unevenness, it is currently the most widely used substitute dermis at Yezak.
homologous dermis
· Made from ingredients extracted from the human body
· Low risk of side effects and high survival rate
· Natural enlargement effect without any foreign body sensation
SuperDerm
SuperDerm is a hydrated allograft used in implants. It is specialized for supporting a wide range of defects in the human body, replacing tissue functions, and forming new autologous tissue through contact with surrounding tissue. It is physically stable enough to replace existing tissue and blood flow.
SureDerm
SureDerm is a freeze-dried, acellular allogeneic dermal graft whose safety and efficacy have been clinically proven. After transplantation, rapid revascularization and remodeling occur, resulting in healthy implantation into the patient’s tissues and preventing immune rejection.
SureDerm Uromax
SureDerm Uromax is an allogeneic dermis that maintains its three-dimensional structure by removing the epidermis and dermal cells that trigger immune responses in human skin. It provides the necessary framework for fibroblast influx, nerve development, and blood vessel regeneration in the dermal layer without immune rejection.
