Penile Curvature A-Z: Causes, Types, and Treatment Options
Penile curvature can easily be corrected. Prof.Osama Shaeer is a world renowned expert in the treatment of penile curvature, with an experience exceeding 30 years in the field of penile surgery, and more than 57 international publications and surgical inventions that are taught in medical and surgical textbooks. This article has the details on the causes of penile deviation and how a curved penis can be straightened.
What is Penile Curvature ?
Penile curvature (also called penile deviation) refers to a condition in which the penis bends instead of being straight when erect. This bend can occur in different directions:
Dorsal penile curvature – upward bend.
Ventral penile curvature – downward bend.
Lateral penile curvature – bend to the left or right side.
Complex penile curvature – a combination of more than one direction.
Causes of Penile Deviation: Congenital vs. Acquired Penile Curvature
Penile deviation can be congenital (present since adolescence or early adulthood, lifelong) or acquired later in life.
Congenital penile curvature usually results from developmental differences in the tunica albuginea, the sheath covering the erectile bodies. One side grows more than the other does, leading to penile deviation.
Acquired penile curvature is most often linked to Peyronie’s disease, where elastic penile tissue is replaced by firm fibrous plaques. Other causes include penile trauma, particularly when the penis is erect.
Treatment of Penile Curvature
In mild Peyronie’s disease, medical therapy may slow down or reverse the process. However, in most cases, especially moderate to severe curvature, surgery is the main treatment. Surgical options fall into two categories:
Shortening techniques
Aim: correct curvature by shortening the longer side of the penis.
Examples: Nesbit procedure and 16-dot plication.
Drawback: penile length loss proportional to curvature severity.
Length-preserving techniques: Shaeer’s corporal rotation
Developed to avoid length loss.
Shaeer’s corporal rotation, created by Prof. Osama Shaeer, which rotates the corpora cavernosa to correct downward (ventral) curvature with minimal or no loss of length.
Best suited for congenital ventral curvature.
3. Plaque incision or excision with grafting
Used in Peyronie’s disease when curvature is severe.
The scarred plaque is incised or replaced with a graft to straighten the penis.
Risks: up to 30% may experience erectile dysfunction.
Frequently combined with penile prosthesis implantation, which restores both rigidity and straightness, offering highly reliable results.
Choosing the Right Surgery for Penile Deviation
Mild to moderate curvature: plication/shortening techniques.
Severe congenital ventral curvature: Shaeer’s corporal rotation.
Severe Peyronie’s with erectile dysfunction: incision/excision with grafting plus penile implant.
Frequently Asked Questions on Penile Curvature
Penile curvature, also known as penile deviation, is when the penis bends instead of being straight during erection. The bend can be upward (dorsal), downward (ventral), sideways (lateral), or a combination of directions (complex)
Penile curvature can be:
Congenital: Present from adolescence due to uneven growth of the tunica albuginea (the sheath around erectile tissue).
Acquired: Often caused by Peyronie’s disease (development of fibrous plaques in the penis) or trauma during erection
Yes. Many men experience some degree of penile deviation. While mild cases may not interfere with sexual function, moderate to severe curvature often requires medical or surgical treatment
Treatment depends on severity and cause:
Medical therapy: May help in early Peyronie’s disease.
Surgical correction: Main option for moderate to severe cases. Techniques include:
Shortening procedures (Nesbit, 16-dot plication) – effective but may reduce penile length.
Length-preserving procedures (Shaeer’s corporal rotation) – correct curvature with minimal or no length loss.
Plaque incision/excision with grafting – used for Peyronie’s disease with severe curvature, often combined with penile implant
Shaeer’s corporal rotation, developed by Prof. Osama Shaeer, is a surgical method that corrects ventral (downward) penile curvature without reducing penile length. It rotates the erectile bodies (corpora cavernosa) to restore straightness
Sensitivity may be reduced temporarily, returns back to normal in almost all cases within a few months. As for erection, procedures for Peyronie’s disease such as plaque excision with grafting, carry a risk (up to 30%) of erectile dysfunction. This is why penile implants are sometimes added in severe Peyronie’s disease
Accordion Content
Mild to moderate curvature: Shortening procedures like plication.
Severe congenital ventral curvature: Shaeer’s corporal rotation.
Severe Peyronie’s with erectile dysfunction: Grafting combined with penile prosthesis implantation
Yes. With proper evaluation and the right surgical technique, penile curvature can be corrected, restoring both straightness and sexual function in most cases
