[Sperm collection for medically assisted procreation in azoospermic patients]

Area of Science:

• Reproductive Medicine
• Urology
• Andrology

Background:

• Infertility affects couples trying to conceive for one year without contraception.
• Male factors contribute to 50% of infertility cases.
• Azoospermia, the absence of sperm in ejaculate, impacts 10-15% of infertile men and requires specific management for assisted reproduction.

Purpose of the Study:

• To evaluate and compare the sperm retrieval rates of various surgical techniques in azoospermic patients.
• To identify the most effective surgical methods for obtaining viable sperm for assisted reproductive procedures.

Main Methods:

• Sperm retrieval from the seminal duct or testicular parenchyma.
• Categorization of techniques into percutaneous, open surgical (Testicular Sperm Extraction - TeSE, Epididymal Sperm Aspiration - ESA), and micro-surgical (micro-TeSE) methods.
• Comparison of retrieval rates across different surgical techniques.

Main Results:

• The study compares the efficacy of different surgical sperm retrieval techniques.
• Specific retrieval rates for percutaneous, TeSE, ESA, and micro-TeSE are analyzed.
• Data will highlight which methods yield higher success rates for sperm recovery in azoospermic individuals.

Conclusions:

• Surgical sperm retrieval is crucial for azoospermic patients undergoing assisted reproduction.
• The choice of technique impacts the availability of suitable gametes.
• Comparative analysis of surgical methods is essential for optimizing infertility treatment outcomes.
