“…Previous studies have demonstrated that the obstructive interval negatively influences pregnancy (Abdelmassih et al, 2002;Borges Júnior et al, 2003), ongoing pregnancy (Abdelmassih et al, 2002;Borges Júnior et al, 2003), implantation (Abdelmassih et al, 2002;Borges Júnior et al, 2003) and miscarriage (Borges Júnior et al, 2003) rates. One study, with severe limited power, failed to demonstrate such associations (Sukcharoen et al, 2000). A recent study from our group showed that the obstructive interval negatively influenced not only the SSR outcomes but also the blastocyst development, implantation and pregnancy rates.…”

“…Vasectomy reversal is another option for vasectomized patients who want to father again, but it may not restore male fertility due to several repercussions of vasectomy such as (i) secondary epididymal blockage and anti-sperm antibody formation (Sukcharoen et al , 2000), (ii) endocrine disruption leading to Sertoli cell vacuolation and dysfunction (Kubota, 1969), (iii) oxidative stress in sperm cells (Shapiro et al, 1998;Kolettis et al, 1999; Practice Committee of the American Society for Reproductive Medicine, 2015) increased interstitial fibrosis in testes (Shiraishi et al, 2003), and (v) increased apoptosis in the seminiferous tubules, Sertoli cells, primary spermatocytes, and round spermatids (O'Neill et al, 2007). The use of PESA or TESA and ICSI is supposed to bypass those factors that interfere with fertility in vasectomized men.…”

“…The influence of the obstructive interval (time elapsed since vasectomy) on the outcomes of ICSI with SSR has been addressed in some studies with conflicting results (Sukcharoen et al, 2000;Abdelmassih et al, 2002;Borges Júnior et al, 2003). This case report will describe a successful twin pregnancy obtained after 25 years of obstructive interval.…”

The couple from this clinical case consisted of a 55 years old male with an obstructive interval of 25 years post vasectomy, and a 38 years old female partner. Both partners had normal results in infertility workup. Five mature oocytes were injected with motile spermatozoa showing morphological alterations, obtained by percutaneous epididymal sperm aspiration. Four oocytes fertilized, and three embryos were transferred with assisted hatching on day three of development, of which one was a high-quality embryo. A clinical pregnancy was confirmed by the detection of two gestational sacs with foetal heartbeats. Pregnancy was ongoing during the submission of this manuscript. The use of ICSI with PESA/TESA should be considered as a feasible alternative when vasectomy reversal fails in vasectomized men wishing to father again. Case reports like this may inspire the counseling of couples that have suffered from a previous vasectomy reversal failure and support the recommendation of ICSI with PESA treatment, which could allow those couples to have their own children, even in the presence of advanced parental age.

“…No difference could be found regarding fertilization rates (FRs), implantation rates (IRs), and pregnancy rates (PRs) between the groups. The authors of the aforementioned study concluded that the interval between vasectomy and surgical sperm retrieval associated with ICSI treatment had no impact on pregnancy outcomes, although it should be noted that the analyzed sample was small and likely lacked statistical power to enable definitive conclusions (23). …”

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.

“…All methods generally provide sufficient numbers of viable sperm for ICSI and often also for cryopreservation. As long as viable sperm can be retrieved, neither the duration of obstruction (10,11) nor the motility of the sperm affects the outcomes achieved with IVF/ICSI (12).…”
