When SSR is needed
Obstructive azoospermia – blockage of sperm transport (vasectomy, congenital absence of vas, infection). PESA or TESA usually successful.
Non-obstructive azoospermia – testicular failure to produce sperm. Micro-TESE offers the best chance of sperm recovery (40-50 percent of cases).
PESA, TESA, Micro-TESE explained
PESA (percutaneous epididymal sperm aspiration) – needle aspiration from epididymis, minimal-invasive, for obstructive cases.
TESA (testicular sperm aspiration) – needle biopsy of testis tissue.
Micro-TESE (microdissection testicular sperm extraction) – open surgical exploration of testis under microscope to identify sperm-producing tubules. Best yield for non-obstructive azoospermia.
Success rates and what follows
Sperm recovery rates depend on cause. Obstructive azoospermia: 95+ percent. Non-obstructive azoospermia: 40-50 percent with micro-TESE. Recovered sperm is used immediately for ICSI or cryopreserved for future cycles.
