Varicocele is potentially a progressive condition that may affect fertility. The authors have encouraged sperm banking for their postpubertal patients with varicocele and aim to evaluate the sperm parameters in this cohort of patients.
With institutional ethical approval, sperm variables (volume, concentration, and forward motility) of patients with postpubertal varicocele who opted for sperm banking were prospectively recorded. The following parameters were also acquired: (a) ultrasound measurement of testicular volume, (b) clinical grade, and (c) venous Doppler. Patients were divided into 2 groups: symmetrical testis (group A) and asymmetrical testis (group B). Testicular asymmetry was defined as greater than 20% difference in testicular volume compared with contralateral testis. Sperm parameters were compared between groups A and B using Mann-Whitney U test and P < .05.
Fifteen patients were included: 10 in group A and 5 in group B. Median semen concentration in group B was significantly lower than group A (3 vs 26 million/mL; P = .04). One hundred percent of group B failed World Health Organisation adult criteria for normal spermiograms compared with 50% of group A.
Sperm concentration and quality was lower in patients with asymmetrical testis. Testicular dysfunction may be present before the onset of testicular hypotrophy. When testicular hypotrophy is present, testicular dysfunction is very likely.
精索静脉曲张可能是一种进行性疾病,可能会影响生育能力。作者鼓励患有精索静脉曲张的青春期后患者进行精子库存储,并旨在评估该队列患者的精子参数。
在获得机构伦理批准的情况下,前瞻性地记录了选择精子库存储的青春期后精索静脉曲张患者的精子变量(体积、浓度和前向运动)。还获得了以下参数:(a)睾丸体积的超声测量,(b)临床分级和(c)静脉多普勒。患者分为两组:对称睾丸(A 组)和不对称睾丸(B 组)。睾丸不对称定义为与对侧睾丸相比睾丸体积差异大于 20%。使用 Mann-Whitney U 检验比较 A 组和 B 组之间的精子参数,P<.05。
共纳入 15 名患者:A 组 10 名,B 组 5 名。B 组的精液浓度中位数明显低于 A 组(3 对 2600 万/mL;P=.04)。B 组 100%的患者未能达到世界卫生组织成人正常精子标准,而 A 组仅 50%的患者未能达到。
睾丸不对称的患者精子浓度和质量较低。睾丸功能障碍可能在睾丸萎缩发生之前出现。当睾丸萎缩存在时,睾丸功能障碍很可能发生。
