Testicular sperm extraction
Testicular Sperm Extraction[edit | edit source]
Testicular Sperm Extraction (TESE) is a surgical procedure used to retrieve sperm directly from the testicles. This technique is primarily employed in cases of male infertility, particularly when there is an absence of sperm in the ejaculate, a condition known as azoospermia.
Indications[edit | edit source]
TESE is indicated in several scenarios, including:
- Non-obstructive azoospermia, where the testicles do not produce enough sperm to appear in the ejaculate.
- Obstructive azoospermia, where a blockage in the male reproductive tract prevents sperm from being present in the ejaculate.
- Cases where sperm retrieval is necessary for intracytoplasmic sperm injection (ICSI) during in vitro fertilization (IVF).
Procedure[edit | edit source]
The TESE procedure involves the following steps:
1. Anesthesia: The patient is typically given local or general anesthesia to ensure comfort during the procedure. 2. Incision: A small incision is made in the scrotum to access the testicle. 3. Tissue Extraction: A small amount of testicular tissue is removed. This tissue is then processed in a laboratory to extract viable sperm. 4. Sperm Retrieval: The extracted sperm can be used immediately for ICSI or frozen for future use.
Advantages and Disadvantages[edit | edit source]
Advantages[edit | edit source]
- Provides an option for men with azoospermia to father biological children.
- Can be performed as an outpatient procedure with minimal recovery time.
Disadvantages[edit | edit source]
- Invasive procedure with potential risks such as bleeding, infection, or damage to the testicular tissue.
- Success rates can vary depending on the underlying cause of infertility.
Alternatives[edit | edit source]
Alternatives to TESE include:
- Microsurgical Testicular Sperm Extraction (Micro-TESE), which uses a microscope to identify and extract sperm from the testicular tissue.
- Percutaneous Epididymal Sperm Aspiration (PESA), which retrieves sperm from the epididymis rather than the testicle.
