Sperm characteristics are routinely assessed in fertility clinics as decisive factors to select sperm for improved intracytoplasmic sperm injection (ICSI) outcomes. A recent study suggests that, in patients with non-obstructive azoospermia, no specific defect or combination of abnormalities in testicular sperm precluded chance of pregnancy, while also suggesting sperm motility and acrosome defects are the proxies relevant to ICSI outcomes.

如何从最具挑战性的样本中选择 ICSI 可行的精子

精子特征通常在生育诊所进行评估，作为选择精子以改善胞浆内精子注射 (ICSI) 结果的决定性因素。最近的一项研究表明，在非梗阻性无精子症患者中，睾丸精子没有特定缺陷或异常组合排除了怀孕的机会，同时也表明精子活力和顶体缺陷是与 ICSI 结果相关的代理。
