Expert PESA/TESA/TESE procedures offering hope to men with severe male infertility through cutting-edge extraction techniques at AFIC Sri Vijaya Puram.
Advanced solutions for male infertility when conventional treatments are not sufficient
In the process of human reproduction, males play an indispensable role. From puberty onward, the male body produces sperm - the essential male reproductive unit. The male reproductive system comprises vital organs including the penis, testes, prostate, and epididymis, each performing crucial functions in the reproductive process.
Male infertility often stems from sperm-related issues, as sperm are directly responsible for fertilization. Some patients experience conditions where their ejaculate contains insufficient healthy sperm, creating significant challenges in conception. This situation can be particularly psychologically distressing for men, directly impacting their self-esteem.
Modern fertility medicine offers solutions through Surgical Sperm Extraction Techniques. When medications fail to improve sperm production, these minimally invasive procedures allow direct retrieval of sperm from reproductive organs. This approach enables the collection of viable sperm for use in IVF treatments, offering new hope to patients with low sperm counts.
At AFIC Sri Vijaya Puram, these extraction techniques have proven highly effective across all age groups, helping hundreds of patients overcome male infertility challenges and achieve successful pregnancies through assisted reproduction.
Understanding the natural process and extraction techniques
Sperm are produced in the testes by seminiferous tubules, which are tightly coiled structures within the testes. These tubules continuously produce sperm throughout a man's lifetime.
After leaving the testes, sperm travel through efferent ducts to the epididymis, where they mature and develop motility and fertility over several weeks.
Depending on the technique, tissues are extracted from the epididymis or from the testes directly, either by aspiration or biopsy under controlled medical conditions.
Sperm are retrieved from the extracted tissue samples in our laboratory. AFIC uses cutting-edge technology to enhance success rates and identify viable sperm.
Advanced surgical techniques tailored to individual patient needs
Percutaneous Epididymal Sperm Aspiration - Minimally invasive procedure retrieving sperm directly from the epididymis with minimal pain and risk. This technique uses a fine needle to aspirate sperm-containing fluid.
Testicular Sperm Aspiration - Collects testicular fluid using needles through a painless, minimally invasive approach. This method directly samples sperm from the testicular tissue.
Testicular Sperm Extraction - Testicular tissue collection under general anesthesia via biopsy with minimally-invasive surgery. Provides larger tissue samples for analysis.
Microsurgical Epididymal Sperm Aspiration - Microscopic biopsy of the epididymis for more accurate sperm collection with enhanced precision and success rates.
Specific medical conditions that benefit from surgical sperm retrieval
Used when blockages prevent sperm release. These procedures bypass the need for surgical clearance, enabling parenthood through direct retrieval. Common causes include congenital absence of vas deferens, previous infections, or surgical complications.
Sperm extraction methods such as TESE and Micro TESE often produce excellent results in treating men with non-obstructive azoospermia. These methods are mainly used in serious cases where the condition cannot be cured with medications alone. By directly retrieving sperm from the testes, these techniques bypass underlying production issues.
Sperm extraction is particularly beneficial for men whose ejaculated sperm display a significantly high DNA Fragmentation Index (DFI). Testicular sperm typically have a lower DFI, making extraction methods like TESA a promising solution for overcoming infertility in these cases.
Necrozoospermia, the condition where a high percentage of ejaculated sperm are dead, can be effectively addressed through testicular sperm extraction. Since testicular sperm are naturally alive, techniques like TESA, TESE, and Micro-TESE can retrieve viable sperm for IVF procedures.
The complete process from extraction to successful fertilization
Once sperm retrieval is complete, the collected sperm undergo rigorous testing to assess their quality. This includes evaluating motility, morphology, and DNA fragmentation. If the sperm meet the required standards, they are prepared for use in ICSI.
Viable sperm are cryopreserved in liquid nitrogen at -196°C for future use. If the sperm are intended for immediate application, they are thawed and prepared for the procedure. This allows for flexible timing of fertility treatments.
If the initial retrieval does not yield sufficient high-quality sperm, doctors may recommend alternative extraction methods. For example, if PESA does not yield results, we can proceed with TESA or TESE, ensuring every possible option is explored.
