Shorter interval between consecutive testicular sperm aspirations and clinical pregnancy after intracytoplasmic sperm injection in obstructive azoospermia: a retrospective cohort study
Retrospective cohort study shows similar clinical pregnancy rates following testicular sperm aspirations in men with obstructive azoospermia, suggesting a practical approach.
Key Points
Clinical pregnancy outcomes remain stable with repeated TESA within three months.
Men with obstructive azoospermia were analyzed in this retrospective cohort study.
Interval differences between TESA definitions were minor and unreliable for decision-making.
Further prospective studies are necessary to validate these findings regarding clinical practice.
