无精子症

In aspermous Patients the reason is the obstruction of spermatogenesis, the most common obstruction occurs in the spermatid level.

在无精症患者中是由生精阻滞所致，最常见的阻滞发生在精子细胞水平。

Results The diagnostic correspondent rate of obstructive and nonobstructive azoospermia by seminal spermatogenic cells examination was 85%, 95.1% respectively. The spermatogenic arrest at spermatid level, spermatocyte level and spermatogonium level or sertoli cells only were 14, 21 and 6 cases respectively.

结果 精液生精细胞学检查对梗阻性和非梗阻性无精症分型诊断的符合率分别为85%、95.1%。41例非梗阻性无精症中，生精阻滞阶段在精子细胞、精母细胞、精原细胞分别为14例2、1例和6例。

Results: Nine subjects did not achieve azoospermia or severe oligozoospermia within the 6 month suppression phase, w...

结果 9名受试者在 6个月的抑制期内未能达到无精子或严重少精子症，其原发避孕失败率为 2 。9/ 1 0 0人年。

Group in the polyester in four patients (36%) to the first 14 months significantly reduced when the sperm count; in the blend in a group (9%) to 10 months, suffering from oligospermia, and that is, the control group semen quality cotton group no change.

在聚酯组中有4位病人（占36％）到第14个月时精子数明显减少；在混纺组中有1位（占9％）到第10个月时患了少精子症，而对照组即纯棉组的精液质量无改变。

PESA/TESA is a convenient, minimally invasive and reliable method in the differential diagnosis of OA and NOA.

PESA/TESA操作简单且创伤小，是对梗阻性与非梗阻性无精子症进行鉴别诊断的可靠方法。

Methods 81 cases with seminal spermatogenic cells examination results were analyzed and compared with the results of epididym puncture biopsy.

分析81例无精子症患者精液生精细胞学检查结果，与睾丸穿刺活检结果对照分析。

Methods According to etiopathogenisis, 30 patients with obstructive azoospermatism were given vasovasostomy,vasoepididymostomy or vasovasostomy plus opposite vasoepididymostong,respectively.

对30例梗阻性无精子症患者，根据其病因分别采取输精管输精管吻合术、输精管附睾管吻合术、输精管输精管吻合术加对侧输精管附睾管吻合术。

Prostasomes and leukocyte were negative correlation in succus prostaticus in the asthenozoospermia group.

在正常精子密度和活力不育组以及少精症组无类似相关性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
