精子與卵子的融合，象徵著一個新生命的誕生。460Please respect copyright.ＰＥＮＡＮＡKiPYN2fcBM

（圖2）近來陸續有研究發現，精子的尾部有著名為Glycylation的結構，由至少三個名為Glycine的氨基酸組成。460Please respect copyright.ＰＥＮＡＮＡEfA7TKuzfl

（圖3）尾部擁有Glycylation結構的精子，接近9成時間都會直行。460Please respect copyright.ＰＥＮＡＮＡP4Dpd3LfHy
而缺乏該結構的精子，則有接近8成的時間會原地打轉。460Please respect copyright.ＰＥＮＡＮＡYzURHu8ixw

（圖4）大概是高機率原地轉圈的關係，尾部缺乏Glycylation結構的精子，與卵子結合的機率將會大減。460Please respect copyright.ＰＥＮＡＮＡ3xdVD7KjyX

尾部缺乏Glycylation結構的精子，其蛋白質Dynein的內部組成結構亦有所不同。460Please respect copyright.ＰＥＮＡＮＡoRXobJKpAN
這亦相信是導致精子原地轉圈的主要原因之一。460Please respect copyright.ＰＥＮＡＮＡhJyahikzfy

如何讓男士們的精子尾部結構保持合適數量的Glycylation結構，將有可能是解決不育的其中一道手段。460Please respect copyright.ＰＥＮＡＮＡPM21d2PSmJ
