“…It seems that the patency rates with the single-armed suture technique for VEs in both reports 5 6 were unexpectedly lower than the double-armed technique. This could be associated with multiple factors such as number of cases, different etiological causes of epididymal obstruction, and different microsurgical modifications or microsurgical materials.…”

“… 5 Besides Zhao, there has been one more report by Binsaleh of 22 cases with the single-armed suture technique in 2014. 6 Average patency rates in their articles were 58% and 59%, respectively. However, data from their studies were limited to a relatively small number of patients.…”

Vasoepididymostomy (VE), as the most challenging procedure in microsurgeries, is often carried out with a double-armed two-suture technique. In this study, we evaluated the efficacy and safety of the single-armed two-suture VEs on humans and studied the factors that could possibly affect the patency rates. From July 2012 to July 2013, we reviewed 81 patients with consecutive primary epididymal obstruction who underwent single-armed two-suture longitudinal intussusception microsurgical VEs by a single surgeon, Kai Hong (KH). At the same time, we analyzed seven factors that possibly related to the patency rates. With the single-armed technique, a total of 81 men underwent the microsurgical VEs. Data on 62 patients were completely recorded. 19 patients were lost to follow-up. Mean age was 31 years old. Mean follow-up time was 8.8 (2-17) months. The patency rate was 66.1% (41/62). Natural pregnancy rate was 34.1% (14/41). Overall pregnancy rate was 22.6% (14/62). No severe surgical complications were noted. With logistic regression test analysis, there were two factors related to a higher patency rate: anastomosis sites (P = 0.035) and motile sperm found in the epididymal fluid (P = 0.006). Motile sperm found in the epididymal fluid were associated with a higher patency rate (OR = 11.80, 95% CI = 1.79, 77.65). The single-armed two-suture longitudinal VE technique is feasible for microsurgical practice. The patency and pregnancy rates are comparable to the doubled-armed technique. Anastomosis sites and motile sperm found in the epididymal fluid were the most two important factors related to higher patency.

“…Microsurgical vasoepididymostomy (MVE) has been demonstrated to be a cost‐effective treatment for men with epididymal obstructive azoospermia (EOA) (Berardinucci et al ., ; Chan et al ., ; Kumar et al ., ). Compared with assisted reproductive technology, microsurgical procedure can avoid female ovarian stimulation, allow for the natural selection of the best spermatozoa and achieve a pregnancy rate of 32% to 40% (Kumar et al ., ; Ho et al ., ; Peng et al ., ; Binsaleh, ).…”

SUMMARYLongitudinal intussusception microsurgical vasoepididymostomy (LIVE) increases the patency rate in men with epididymal obstructive azoospermia (EOA). Here, we retrospectively analyzed the early outcomes of our modified single-armed suture technique for LIVE in men with EOA. From February 2012 to November 2013, 51 men received the modified technique and 39 men provided at least one post-operative semen sample. The mean age was 31.4 years old for the men and 29.2 years old for their female partners. The mean duration of obstruction was 34.3 months. Patency was noted in 24 (61.5%) men and pregnancy was reported in 15 (38.5%) female partners. Motile spermatozoa in the epididymal fluid were observed intraoperatively in 14 (58.3%) patent men and 3 (20%) non-patent men, respectively (p < 0.05). In the patent cohort, the mean ages of the pregnant and non-pregnant female partners were 26.5 and 32.7 years old, respectively (p < 0.05). Our modified technique resulted in favorable patency and pregnancy rates in this study. Sperm motility in epididymal fluid and female partner age were important factors associated with the patency and pregnancy rates.

“…Azoospermia, an essential factor for male infertility, is categorised into obstructive and nonobstructive azoospermia (Chen et al ., ; Qin et al ., ). Obstructive azoospermia is mainly caused by bilateral occlusion at genital tract or ejaculatory dysfunction, and presents normal spermatogenesis, but nonobstructive azoospermia exhibits abnormal histopathology (Binsaleh, ; Esteves et al ., ).…”

Neutral alpha-1,4-glucosidase and fructose levels contribute to discriminating obstructive and nonobstructive azoospermia in Chinese men with azoospermia

Nowadays, whether neutral alpha-1,4-glucosidase (NAG) and fructose levels are contributed to discriminating obstructive and nonobstructive azoospermia in Chinese azoospermic patients remains unclear. In this study, we retrospectively analysed the levels of NAG and fructose in 229 patients with obstructive azoospermia and 415 patients with nonobstructive azoospermia from three different medical central. Results indicated that NAG and fructose levels in patients with nonobstructive azoospermia were significantly higher compared with those with obstructive azoospermia (P < 0.05). According to the reference value of NAG and fructose defined by the World Health Organization (WHO, 2010), decreased level of NAG was observed in 77.3% of patients with obstructive azoospermia, which was significantly higher than those with nonobstructive azoospermia (55.2%, P < 0.0001). Low level of fructose was observed in 48.0% of patients with obstructive azoospermia, which is also obviously higher than those with nonobstructive azoospermia (31.8%, P < 0.0001). Moreover, the decrease of both NAG and fructose was only recorded in 3.7% of patients with SCO syndrome, 5.0% of patients with severe hypospermatogenesis and 18.2% of patients with maturation arrest. Therefore, our results indicated that NAG and fructose levels are contributed to discriminating obstructive and nonobstructive azoospermia in Chinese patients based on the histological types of testes.
