Species preservation depends on the success of fertilization. Sperm are uniquely equipped to fulfill this task, and, although several mechanisms are conserved among species, striking functional differences have evolved to contend with particular sperm-egg environmental characteristics. This review highlights similarities and differences in sperm strategies, with examples within internal and external fertilizers, pointing out unresolved issues.
物种的保护取决于受精的成功。精子具有独特的能力来完成这项任务,尽管几种机制在物种间是保守的,但为了应对特定的精子-卵子环境特征,已经进化出了显著的功能差异。本综述强调了内部受精和外部受精的精子策略的相似和不同之处,并举例说明了这一点,指出了尚未解决的问题。
