    What is a spermatocele?

    Scrotal Hydrocele Sclerotherapy Doctor Los Angeles Orange County San Diego

    A spermatocele or spermatic cyst is an abnormal sac in the upper part of the epididymis (the epididymis is a coiled tube in the testicle that collects and transports sperm). In most cases, a spermatocele is a smooth, soft mass that contains clear or milky fluid, and sometimes, sperm. The exact reason why spermatoceles develop is unknown but it is believed to be due to a blockage in one or more of the multiple tubes within the epididymis. Spermatoceles are a relatively common problem and are often discovered by chance. Incidental spermatoceles are found in 30% of patients undergoing ultrasound of the scrotum for other complaints.

    Why treat a spermatocele?

    Spermatoceles are non-cancerous and they do not typically affect fertility. Most spermatoceles are painless. However, a spermatocele can grow large enough to cause discomfort, pain, and a sensation of heaviness or fullness. Spermatoceles are diagnosed by ultrasound which can be done in the office.

    Scrotal Hydrocele Sclerotherapy Doctor Los Angeles Orange County San DiegoIf the spermatocele becomes large enough to cause a level of discomfort, then treatment maybe recommended. Generally, the spermatocele should be at least 2 cm to be amenable to treatment. The first step is a diagnosis, which can be done by an ultrasound in the office. Our doctor is a board certified imaging specialist in addition to specializing in minimally invasive procedures and will perform the diagnostic ultrasound during your visit. Generally, the consultation and treatment can be done on the same visit.

    Treatment Options

    There are two types of treatments for spermatoceles: sclerotherapy and surgical excision.

    Spermatocele Aspiration & Sclerotherapy

    Sclerotherapy is an outpatient procedure performed in the office that involves removing the fluid collection (aspiration) through a small tube followed by injection of a medication (sclerotherapy) that helps close the cavity that was containing the fluid. Our specialist applies a local anesthetic to make the procedure essentially pain-free. There is no downtime and you will walk out of the office right after the procedure.

    This is a minimally invasive, quick, safe, and effective treatment for a spermatocele. The risk of complications is low and patient satisfaction is high.2 Unlike surgical excision, you will not need to wear athletic scrotal support, ice or sutures.

    Surgical Excision or Spermatocelectomy

    While we do not perform surgical removal of spermatocele you should understand and be informed of your surgical option. This procedure involves making an incision in your scrotum followed by dissection of the spermatocele without damaging surrounding epididymal tissue. The fluid and sac are then removed. The space is then sutured closed. After surgery, you need to wear an athletic support to protect the incision. You will also need pain medication and ice packs to keep the swelling down. Recovery from spermatocelectomy can take up to 5 days. Possible complications include continued pain, recurrence of the spermatocele, hematoma, and infection. Damage to the epididymis and/or vas deferens during the surgery can affect fertility. In one study, nearly 20% of patients who underwent surgical spermatocelectomy experienced postoperative complications such as treatment failure, chronic pain, and scrotal abscess formation.

    What is the right treatment for me?

    If you’ve been diagnosed with a spermatocele it’s important to gain at least a basic understanding of your treatment options. Every approach to treatment has its pros and cons. Ultimately, the treatment you choose will depend on what your doctor recommends and what feels best to you. Some patients obtain surgery while others prefer a non-surgical option such as sclerotherapy, and only seek surgery if the treatment is not effective for them.

    You should seek the expert advice of your urologist and interventional radiologist to further understand your options and expected outcomes.

    Our interventional specialist has performed over 5,000 ultrasound and image-guided procedures. While most hydrocele aspirations are done blindly, you can rest assured that your experience will be painless at CVI as the procedure is performed with precision with ultrasound guidance by our specialist.

    Can't I just have aspiration to remove the spermatocele fluid?

    Aspiration alone will not be sufficient. If your specialist only removes the fluid it will only be a matter of time that the spermatocele will return causing your symptoms again. Sclerotherapy is important as it closes the cavity, preventing the fluid from returning.

    Our specialist performs the aspiration first using ultrasound-guidance, which shows precisely the location of the needle so that the testicle does not get punctured minimizing risks. Make sure that the specialists performing this procedure is trained in ultrasound-guided procedures.


    Sclerotherapy is a minimally-invasive, non-surgical, outpatient treatment for scrotal spermatocele. It is quick, safe, and effective, and it avoids the expense and potential complications of surgery. There are no major incisions, no stitches, and no downtime. You can return to work immediately after the treatment.

    The initial success rate of a single spermatocele aspiration and sclerotherapy procedure is more than 75%, meaning 3 out of 4 patients are symptom-free just after one treatment. With multiple treatments, the success rate improves to nearly 95%.

    Consultations are available via an online video telehealth platform or in person at one of the offices in Los Angeles, Orange County or San Diego.  Why should you choose us? Read here.
