OBJECTIVE: To investigate the effect of azoospermia

type on fertilization and clinical pregnancy rates when

microdissection testicular sperm extraction (TESE) is

performed for sperm retrieval

in nonobstructive azoospermia

(NOA).

STUDY DESIGN: Patients

who underwent microdissection

TESE for NOA and conventional

TESE for obstructive

azoospermia (OA) were

included in the study. Intracytoplasmic

sperm injection (ICSI) results were compared

between groups.

RESULTS: The mean ages in the 2 groups were similar.

FSH and LH levels in the NOA group were significantly

higher than those of the OA group. Between groups

there was no statistically significant difference in testosterone

levels. The sperm retrieval rate was 58.56%

in NOA. Fertilization and clinical pregnancy rates were

similar for patients with NOA and OA.

CONCLUSION: In patients with NOA, microdissection

TESE accurately determines active spermatogenesis

areas via the high identification power of the operative

microscope. From these areas surgeons can collect

healthier spermatozoa, which can result in better ICSI

outcomes, the results of which are similar to those with

OA.
