Zusammenfassung: | Objective: To compare the effect of a short (4 days) or a long (14 days) abstinence period on sperm retrieval by extended sperm preparation in patients with nonobstructive azoospermia scheduled for testicular biopsy and intracytoplasmic sperm injection (ICSI).
Design: A prospective case control study.
Setting: Male infertility clinic in a university hospital.
Patient(s): Fifty male patients with nonobstructive azoospermia, scheduled for testicular biopsy for ICSI.
Intervention(s): Diagnosis of nonobstructive azoospermia and a thorough microscopic search for sperm cells (extended sperm preparation).
Main Outcome Measure(s): The number of sperm cells collected, sperm motility, and total motile sperm count after short and long abstinence periods
Result(s): There was a significant difference between long and short abstinence with an increase in sperm count (log-to-log transformed analysis of variance
