Sperm retrieval

Sperm retrieval is a medical procedure that involves the extraction of sperm directly from the testes or epididymis. This procedure is often performed when there is a blockage preventing sperm from being ejaculated or when there is a problem with sperm production.

Types of Sperm Retrieval Procedures

There are several types of sperm retrieval procedures, including:

• Percutaneous Epididymal Sperm Aspiration (PESA): This is a non-surgical procedure where a needle is inserted into the epididymis to extract sperm.
• Testicular Sperm Aspiration (TESA): This procedure involves inserting a needle into the testes to extract sperm.
• Testicular Sperm Extraction (TESE): This is a surgical procedure where a small incision is made in the testes to extract sperm.
• Microsurgical Epididymal Sperm Aspiration (MESA): This is a surgical procedure where a small incision is made in the epididymis to extract sperm.

Indications for Sperm Retrieval

Sperm retrieval is often indicated for men who have:

• Azoospermia: This is a condition where there is no sperm in the ejaculate.
• Obstructive Azoospermia: This is a condition where there is a blockage in the reproductive tract that prevents sperm from being ejaculated.
• Non-obstructive Azoospermia: This is a condition where there is a problem with sperm production.

Risks and Complications

Like any medical procedure, sperm retrieval carries some risks and potential complications, including:

• Infection: This can occur if bacteria enter the body during the procedure.
• Bleeding: This can occur if a blood vessel is damaged during the procedure.
• Pain: This can occur during and after the procedure.

Success Rates

The success rate of sperm retrieval procedures varies depending on the specific procedure used and the underlying cause of the male infertility. In general, the success rate is higher for surgical procedures such as TESE and MESA compared to non-surgical procedures such as PESA and TESA.
