Micro TESE India, Microdissection Testicular Sperm Extraction in India
Dr. Hrishikesh Pai pioneers Micro TESE and microdissection techniques in India, revolutionising male infertility treatments.
What is Micro TESE?
Micro TESE (Microscopic Testicular Sperm Extraction) is an advanced surgical technique used to retrieve sperm from the testicles of men with non-obstructive azoospermia, a condition characterized by the absence of sperm in the ejaculate due to testicular dysfunction. Unlike conventional TESE, which involves randomly sampling testicular tissue, Micro TESE utilizes high-powered microscopes and precision instruments to identify and extract sperm-containing tubules within the testes with greater accuracy.
Understanding Micro TESE:
- Patient Selection: Micro TESE is typically recommended for men with non-obstructive azoospermia, where sperm production within the testes is impaired due to factors such as genetic abnormalities, hormonal imbalances, or testicular injury.
- Surgical Procedure: During Micro TESE, a small incision is made in the scrotum, and the testicular tissue is exposed. Using a microscope, the surgeon carefully identifies and isolates sperm-containing tubules, which appear as larger, more translucent structures within the testicular tissue.
- Sperm Retrieval: Once the sperm-containing tubules are identified, they are microsurgically dissected and removed from the testicle. The extracted tissue is then examined under the microscope to confirm the presence of sperm.
- Sperm Utilization: The retrieved sperm can be used for intracytoplasmic sperm injection (ICSI) during in vitro fertilization (IVF) procedures, where a single sperm is injected directly into an egg to facilitate fertilization.
Key Benefits of Micro TESE:
- Improved Sperm Retrieval Rates: Micro TESE offers higher sperm retrieval rates compared to conventional TESE procedures, as it allows for the targeted extraction of sperm-containing tubules, minimizing tissue damage and maximizing the chances of finding viable sperm.
- Reduced Tissue Trauma: The microsurgical approach of Micro TESE minimizes tissue trauma and preserves the structural integrity of the testicular tissue, leading to faster recovery times and reduced postoperative discomfort for patients.
- Enhanced Fertility Outcomes: By retrieving higher-quality sperm, Micro TESE can improve the success rates of IVF-ICSI procedures for couples struggling with male factor infertility due to non-obstructive azoospermia.
Considerations and Success Rates:
While Micro TESE offers significant advantages for men with non-obstructive azoospermia, it's essential to recognize that success rates can vary depending on individual factors such as the underlying cause of infertility, the severity of testicular dysfunction, and the experience of the surgical team performing the procedure. Additionally, not all men with non-obstructive azoospermia may have retrievable sperm, and alternative options such as sperm donation or adoption may need to be considered.
In conclusion, Micro TESE is a highly specialized surgical technique that has revolutionized the treatment of non-obstructive azoospermia, offering hope to couples facing male factor infertility. With its precision and effectiveness in sperm retrieval, Micro TESE has become a valuable tool in assisted reproduction, enabling many couples to fulfill their dream of parenthood.
