These maturation changes still occur even when spermatozoa are confined to caput epididymidis by ligatures. 用结扎的方法将精子限制在附睾头内,这些成熟变化仍可能发生。
Methods: ICSI and SUZI were employed to obtain the assisted fertilization of mouse sperm from caput epididymidis and cauda epididymidis. 方法:用显微注射法把小鼠附睾头和附睾尾精子注入卵母细胞的胞质内或卵周隙进行显微受精。
