Secondary azoospermia after vasovasostomy.

Objectives: To determine the frequency of secondary azoospermia after microsurgical vasovasostomy and to determine what factors increase the risk of its occurrence.

Methods: We performed a retrospective review of three surgeons' experience. Patency was defined as the presence of sperm in at least one postoperative semen sample.

Pregnancy outcomes after vasectomy reversal for female partners 35 years old or older.

Purpose: We review the outcomes after vasectomy reversal for couples with female partners 35 years old or older.

Materials And Methods: A retrospective review of experience at 2 institutions was performed. Patency was defined as the presence of motile sperm.

Outcomes for vasovasostomy with bilateral intravasal azoospermia.

We conducted an evaluation of outcomes for microsurgical vasectomy reversal in which sperm are absent from the vas fluid in order to determine a threshold obstructive interval when vasoepididymostomy (VE) may be indicated. Vasectomy reversal was performed for 32 patients with intravasal azoospermia: 25 received bilateral vasovasostomy (VV), 1 had a bilateral VV, 5 underwent VV/VE, and 1 had bilateral VE. Overall, the patency rate was 50% (14 of 28).

Outcomes for vasectomy reversal performed after obstructive intervals of at least 10 years.

Objectives: To determine the outcomes for vasectomy reversal performed after at least 10 years of obstruction.

Methods: We performed a retrospective review of three surgeons' experience with microsurgical vasectomy reversal for obstructive intervals of at least 10 years.

Results: The overall pregnancy rate was 37%.
