“…Azoospermia, defined as the complete absence of sperm from the ejaculate, affects approximately 1% of all men and 5 to 10% of all subfertile males seeking care (1,2). Although the majority of cases are secondary to an impairment of testicular function, a bilateral obstruction of the male genital tract causes azoospermia in up to 20 to 40% of cases (3).…”

Obstructive azoospermia is a relatively common male infertility condition. The main etiologies of obstructive azoospermia include congenital, surgical-derived, traumatic and post-infectious cases. Although seminal tract reconstruction is a cost-effective treatment in most cases, this approach may not be feasible or desired in some cases. In such cases, assisted reproduction techniques offer a method for achieving pregnancy, notably via sperm retrieval and intracytoplasmic sperm injection. This process requires several considerations and decisions to be made, including the cause and duration of obstruction, which sperm retrieval technique to use, and whether to use fresh or frozen-thawed sperm. We present a review of obstructive azoospermia and assisted reproduction techniques, highlighting the most relevant aspects of the decision-making process for use in clinical practice.

AimEvaluation of a protocol for the management of seminal tract obstruction. Patients and methods Eighty infertile men with obstructive azoospermia were enrolled in this study. Intraoperative vasography pinpointed the site (or sites) of obstruction. According to the algorithm, single-site or multiple-site obstructions were managed by various combinations of epididymovasostomy, vasovasostomy, transurethral resection of the ejaculatory ducts, and pelviscrotal vasovasostomy. Results Cases (92.5%, 74 out of 80 patients) showed the appearance of spermatozoa in semen after surgery. The average count was 14 million/ml and the average motility was 40%. Simultaneous multiple-site obstruction was detected and managed in 32 out of 80 patients (40%). ConclusionThe modest success rate for surgical repair of seminal tract obstruction may be attributable to missing or failure to manage multiple-site obstruction, which appears to be common. The proposed algorithm guides the surgeon to full restoration of patency of the seminal tract along its whole length on the basis of proper diagnostic and corrective measures.

“…Other indications are vascular erectile dysfunction and penile or testicular vascular trauma. Obstructions of the male genital tract represent 5-10% of the causes of male infertility and in 70-80% of these men surgical repair can be performed [11].…”

A B S T R A C TMicrosurgical vasectomy reversal is a challenge for the physician but successful treatment depends on the experience and skills of the surgeon. Fertility can often be restored, thus avoiding the need for artificial reproductive techniques. Also, the surgical procedures can be combined with sperm aspiration and cryopreservation, to be used for Intracytoplasmic sperm injection (ICSI) in cases of surgical failure. We describe the results of 217 vasovasostomy procedures, with special emphasis on recent technical refinements and prognostic indicators.
