Sperm Extraction (TESA, TESE, PESA, MESA) to Treat Male Infertility
Regain fertility with testicular sperm extraction (TESE, PESA, MESA) at Reproductive Fertility Center
Contact UsInfertility can occur in men for various reasons. Little to no motile sperm may be present in their ejaculate, blockages may prevent the delivery of sperm, or ejaculation may not be possible. Potential reasons for these issues include a previous vasectomy, being born without a vas deferens, and having a low sperm count due to lifestyle factors or genetics.
Sperm extraction procedures can help men suffering from these conditions improve their fertility despite these causes. The sperm (spermatozoa) can be harvested directly from in or near the testes, and the healthiest, most viable sperm can be isolated. The sperm can then be used with other fertility treatments to achieve fertilization.
What are TESA, TESE, PESA, and MESA?
TESA: Testicular Sperm Aspiration
Testicular sperm aspiration involves using a small needle to extract sperm directly from the testis (testicle).
While this is generally done under local anesthesia, it can be done under general anesthesia if you are anxious or nervous and prefer to be asleep during the procedure.
TESE: Testicular Sperm Extraction
Testicular sperm extraction is a surgical procedure that uses a small incision in the testis (testicle). A small portion of testicular tissue that contains sperm is removed.
This procedure is performed with the patient under general anesthesia.
PESA: Percutaneous Epidydimal Sperm Aspiration
The epididymis is a tube behind the testis that joins the testicle to the vas deferens. PESA involves using a small needle to extract sperm from the epididymis.
This can be performed with the patient under local or general anesthesia based on their preference.
MESA: Microsurgical Epidydimal Sperm Aspiration
Microsurgical epidydimal sperm aspiration uses a small incision in the testicle to access the epididymis (the tube behind the testicle). A small needle is then used to aspirate sperm from the epididymal tubule.
MESA is performed with the patient under general anesthesia.
Is sperm extraction painful?
TESA, TESE, MESA, and PESA are performed using the necessary anesthesia to ensure the procedure is painless.
What does the recovery process look like after sperm extraction?
These procedures will have a recovery period that can include moderate discomfort. Patients can manage these side effects with prescription or over-the-counter medication.
How do I know if I need TESE, TESA, PESA, or MESA?
Dr. Saadat will usually make a recommendation for you based on tests he performs and suspected causes of infertility. TESA is most often used when the testes produce viable sperm that can’t be ejaculated. TESE is more commonly used when there is an issue with the production of healthy sperm within the testicles.
Do I need to know the cause of my infertility before undergoing sperm extraction?
Sperm extraction procedures can be used to overcome a wide variety of male infertility concerns. Therefore, knowing the specific infertility concern is not always critical. However, knowing the cause of your infertility may be beneficial in determining which procedure is best for you.
