无精子症(英语:Azoospermia俗称空枪空炮空包蛋[来源请求],是指男性精液中没有精子症状[1]。无精子症与男性不育密切相关,但许多都是可以治疗的。在人类中,无精子症影响了约1%的男性群体[2],造成了大约20%的男性不育[3]

分类

无精子症可以根据病因部位大致分为以下三种类型[3],许多情况仅造成一定程度的少精子症而非无精子症。

睾丸前因素

睾丸前因素主要有染色体异常,下丘脑垂体疾病引起的睾丸发育不良。

睾丸本身因素

睾丸本身因素主要有隐睾睾丸肿瘤、外伤、睾丸炎及全身疾病或肿瘤经化疗放疗后引起的睾丸病变。

睾丸后因素

睾丸后因素主要是附睾和输精管道的梗阻或发育不良,或医源性损伤(如输精管结扎或手术误伤)。

未知因素

特发性无精症(Idiopathic azoospermia)即是指原因不明的无精子症,可能由多重因素引起,比如老化和超重。
