Marmar Surgery for Varicocele: Procedure, Benefits and Recovery
Marmar surgery, also known as microsurgical subinguinal varicocelectomy, is a surgical technique used to treat varicocele.

Marmar surgery, also known as microsurgical subinguinal varicocelectomy, is a surgical technique used to treat varicocele. The procedure is performed through a small incision in the groin area, below the external inguinal ring, and uses optical magnification to identify and close the abnormal veins while preserving important surrounding structures.
The technique is named after urologist Joel L. Marmar, who, together with Young Kim, published results of a modified microsurgical subinguinal approach in 1994.
When is Marmar surgery recommended?
Not every varicocele requires surgery. Treatment may be considered when a clinically significant varicocele is associated with infertility and abnormal semen parameters, persistent scrotal pain, or impaired testicular development in adolescents.
Current European Association of Urology guidance recommends treatment in selected infertile men with a clinical varicocele, abnormal semen parameters and otherwise unexplained infertility. Surgery is generally not recommended solely for a subclinical varicocele or for infertile men with normal semen analysis.
How is Marmar surgery performed?
During microsurgical subinguinal varicocelectomy, the surgeon makes a small incision in the groin and accesses the spermatic cord without opening the abdominal cavity.
Using an operating microscope, the surgeon identifies the dilated veins responsible for the varicocele and ligates them to interrupt abnormal venous blood flow. At the same time, the technique is designed to preserve the testicular artery, vas deferens and lymphatic vessels.
The use of magnification is particularly important because the spermatic cord contains multiple small arteries, veins and lymphatic vessels that need to be distinguished during surgery.
What are the advantages?
The microsurgical approach allows the surgeon to identify small veins while protecting arteries and lymphatic vessels. Current EAU evidence indicates that microsurgical varicocelectomy is among the most effective surgical approaches for varicocele and may have lower recurrence and complication rates than non-microsurgical techniques.
However, no surgical method can guarantee improvement in fertility or complete resolution of symptoms.
Recovery after Marmar surgery
Microsurgical varicocelectomy can often be performed as an outpatient procedure, allowing the patient to return home the same day. Temporary discomfort, bruising or swelling may occur after surgery.
The surgeon will provide individual instructions about wound care, physical activity, exercise and returning to work or sexual activity. Follow-up may include physical examination and, when surgery was performed for infertility, repeat semen analysis.
FAQ
Is Marmar surgery the same as varicocelectomy?It is a specific microsurgical, subinguinal technique for performing varicocelectomy.
Can varicocele return after Marmar surgery?Recurrence is possible after any varicocele treatment, although microsurgical approaches are associated with relatively low recurrence rates.
Does Marmar surgery improve fertility?Varicocele repair may improve semen parameters and fertility outcomes in appropriately selected men, but pregnancy cannot be guaranteed.
