Summary
Testicular biopsy, crucial for infertility management and sperm retrieval for ICSI, shows open biopsy as most reliable. Microsurgical techniques can reduce complications.
Area of Science:
- Reproductive Medicine
- Urology
- Andrology
Background:
- Testicular biopsy traditionally served diagnostic roles in infertility.
- Assisted reproductive technologies now utilize testicular biopsy for sperm retrieval for intracytoplasmic sperm injection (ICSI).
Purpose of the Study:
- To review the feasibility and techniques of testicular sperm extraction for ICSI.
- To compare the efficacy of different testicular biopsy methods.
- To discuss advancements in testicular biopsy and associated procedures.
Main Methods:
- Review of current literature on testicular biopsy techniques.
- Comparison of open testicular biopsy with less invasive methods (fine needle aspiration, percutaneous needle biopsy).
- Discussion of microsurgical techniques to minimize complications.
Main Results:
- Less invasive techniques are effective, especially for obstructive azoospermia.
- Open testicular biopsy is considered more reliable for obtaining testicular specimens.
- Microsurgical approaches can reduce complication rates.
Conclusions:
- Open testicular biopsy remains a reliable method for sperm retrieval for ICSI.
- Advancements include tissue processing, sperm cryopreservation, in vitro maturation, and microinjection of precursor cells.
