MESA
Pronunciation: MEE-sah
Also written as: MESA — Microsurgical Epididymal Sperm Aspiration
Microsurgical epididymal sperm aspiration, a surgical technique for sperm retrieval in obstructive azoospermia.
Full Definition
MESA (Microsurgical Epididymal Sperm Aspiration) is a surgical procedure used to retrieve sperm directly from the epididymis in men with obstructive azoospermia. This microsurgical technique allows for the collection of mature, motile sperm that can be used immediately for ICSI or cryopreserved for future use. The procedure is performed under general anesthesia using an operating microscope to identify and aspirate sperm from individual epididymal tubules. MESA typically yields higher numbers of sperm compared to other retrieval methods and has good success rates when combined with assisted reproductive technologies.
Usage
Usage note: Always spell out on first use in formal documents; distinguish from other sperm retrieval acronyms.
