Varicocele
How Is Varicocele Surgery Performed?
Varicocele surgery is performed using a microsurgical technique. A 2 cm incision is made in the groin area to access the testicular veins. Under a microscope, the enlarged veins are carefully separated from other vessels and ligated.
How Long Does Varicocele Surgery Take?
Since varicocele surgery is performed using microsurgical methods, all affected veins in the area must be tied. Depending on whether the surgery is unilateral or bilateral and the number of veins involved, the duration may vary between 1 to 2.5 hours.
Are There Risks Associated with Varicocele Surgery?
Because varicocele surgery is performed microsurgically, the complication rate is very low. The most important risk is accidental ligation of the testicular artery, which may lead to reduced blood supply and shrinkage of the testicle after surgery. However, under microscopic visualization, arteries and veins can be clearly distinguished, making this complication extremely rare today.
The risk of hydrocele (fluid accumulation around the testicle) has also significantly decreased. As with all surgical procedures, risks such as postoperative infection and bleeding should not be ignored. With proper sterilization and bleeding control, these risks are minimized.
Are There Different Treatment Methods for Varicocele?
Varicocele can be treated using different surgical and radiological methods.
Varicocele embolization: Through interventional radiology, an occlusive material can be injected into the enlarged veins via a groin entry. However, this method may carry risks such as migration of the occlusive material, loss of effectiveness over time, pain, and allergic reactions. Therefore, it is not widely recommended in international guidelines.
Other surgical approaches include inguinal, high inguinal, and laparoscopic techniques. However, microsurgical subinguinal varicocelectomy performed under a microscope is considered the gold standard.
Does Varicocele Recur?
Although there are different treatment options, recurrence rates after microsurgical varicocelectomy are extremely low, approaching nearly zero.
What Is the Recovery Time After Varicocele Surgery?
After microsurgical varicocele surgery, patients can return to normal daily activities within 2–3 days and resume routine work life within 7–10 days. Strenuous physical activities and exercise may require 4–6 weeks before resumption.
When Do Sperm Parameters Improve After Surgery?
To evaluate the effect of varicocele surgery on sperm, the sperm production cycle must be considered. The process from germ cell to mature sperm in the testicle takes approximately 90 days. Therefore, sperm parameters are typically evaluated every 3 months after surgery.
The most significant improvement in sperm production is usually observed around the 6th month. If improvement is noted at 6 months, further enhancement may continue at the 9th and 12th months.
If no improvement is observed at 6 months, additional recovery related to surgery is unlikely, and alternative treatment options should be considered. Approximately 60–70% of patients experience improvement in sperm parameters. Around 30–40% may show no change, and less than 1% may experience worsening, which is more commonly seen in bilateral varicocele cases.
What Should Patients Pay Attention to After Surgery?
In the early postoperative period, patients should avoid sports activities, heavy exercise, and sexual activity according to their doctor’s advice. Sexual activity is usually postponed for 15–20 days, while strenuous activities and sports should be avoided for 4–6 weeks.
Is Testicular Pain Normal After Surgery?
As with any surgical procedure, some neuralgia-like discomfort may occur due to minor nerve irritation in the testicular area. However, surgery should not be performed solely for testicular pain without infertility. Many underlying causes may be responsible for pain, and it may persist even after surgery.
Is Swelling Normal After Varicocele Surgery?
Mild testicular sagging on the operated side may occur due to loosening of connective tissue. However, significant swelling is usually related to hydrocele (fluid accumulation). This is more common in non-microsurgical methods. In microsurgical procedures, hydrocele occurs in less than 1% of cases because lymphatic vessels are preserved.
Can Patients Have Children After Varicocele Surgery?
After surgery, 60–70% of patients show improvement in sperm parameters. If no improvement is observed by the 6th month, alternative treatments such as intrauterine insemination (IUI) or IVF may be recommended depending on age, female factor, and sperm parameters.
For younger patients with abnormal sperm parameters who wish to conceive naturally, surgery may be beneficial. However, in older patients, assisted reproductive techniques such as IVF may be more appropriate to avoid losing time. Infertility should always be evaluated as a couple-based condition.
What Happens If Varicocele Is Not Treated?
Varicocele is a chronic condition and does not resolve spontaneously. If left untreated, it may lead to testicular shrinkage, increased varicocele size, worsening sperm parameters, and hormonal imbalances over time. However, not every varicocele requires surgery.
