精液分析显示我的精子形态异常。请问这意味着什么?

回答 Sevann Helo, M.D.

精子形态(精子的大小和形状)是精液分析中评估男性不育症的一个因素。精子形态学结果报告给出显微镜下观察到的显示正常的精子的百分比。

正常精子的头部呈椭圆形,尾部很长。异常的精子存在头部或尾部缺陷,如头部巨大或畸形,或尾巴弯曲或成双。这些缺陷可能影响精子到达并穿透卵子的能力。然而,常见出现大比例畸形精子。通常,精液样本中仅 4% 到 10% 的精子正常,这意味着显微镜下绝大多数精子看起并不完美。

人们对精子形态知之甚少,且可能有主观性。在同一家实验室,使用相同的评分技术,同一精液样本的得分可能有所不同。大多数男性生育专家一致认为,精子形态在预测怀孕方面的作用尚不清楚,除非几乎 100% 的精子异常,否则将无法预测不孕不育症。

除了精子形态,典型的精液分析还评估:

  • 精液量
  • 总精子数
  • 精子浓度
  • 活力(成活率)
  • 运动(动力)

精液分析异常并不意味着您不育。许多精液分析值低的男性仍可成为父亲,只是可能耗时更长。如果您和性伴侣不能通过性交怀孕,则可以选择辅助生殖技术,如体外受精。
