What is Surgical Sperm Retrieval and Extraction?
Surgical Sperm Retrieval and Extraction includes taking sperm directly from the testicles or epididymis for male patients with certain types of infertility. In this technique sperm is retrieved, by collecting sperm from areas like the epididymis or vas deferens, where sperm is already matured and stored. Sperm extraction is a more invasive procedure that is used for obtaining sperm directly from testicular tissue, usually when sperm production is severely impaired.
Techniques of Surgical Sperm Extraction
When natural ejaculation is not possible several techniques are used for surgical sperm extraction and festival such as:
Tests Conducted to Diagnose Female Infertility
diagnose the cause of female infertility. The process typically begins with a detailed medical history and a physical examination.
- Percutaneous Epididymal Sperm Aspiration (PESA)
PESA is a minimally invasive procedure where a thin needle is used to draw sperm directly from epididymis. This method is ideal for men and performed under local anesthesia. Thin needle is inserted through the scrotal skin into the epididymis to aspirate sperm-containing fluid. It's the most effective for men with obstructive azoospermia, or one who had vasectomy in the past or blockage in the reproductive tract. - Testicular Sperm Aspiration (TESA)
TESA involves using a fine needle to aspirate sperm directly from the testicular tissue.It often used when sperm cannot be retrieved and there is blockage preventing sperm from reaching ejaculation. It is suitable for men with obstructive azoospermia and sometimes for non-obstructive azoospermia and usually such sperm is used for ICSI like treatments. Impair. TESA is less invasive than open surgery but may yield fewer sperm in some cases. - Microdissection Testicular Sperm Extraction (Micro-TESE)
Micro-TESE is a highly specialized surgical procedure performed under a microscope to retrieve sperm when sperm is very low or absent. Micro TESE is helpful when traditional methods fail. In this the male partner is put under general anesthesia, a small incision is made in the testicle,and extraction is done by checking the healthiest seminiferous tubules likely to contain sperm.
