6种蝙蝠精子储存现象的组织学观察

Histological Study on Sperm Storage in Six Microchiropteran Species

精子储存是蝙蝠的生殖对策之一,有些种类的蝙蝠能将成熟精子在交配前(雄性)或交配后(雌性)储存在附睾或者输卵管及子宫内数月。采用冰冻切片和苏木精-伊红(H.E)染色法,观察了6种蝙蝠的睾丸、附睾、卵巢、输卵管和子宫,发现5种蝙蝠有精子储存现象。另外,本文还讨论了不同生殖对策蝙蝠的地理分布。

Sperm storage is a reproductive strategy in bats. Some species of bats can store mature spermatozoa in epididymis （male） or oviducts and uterus （female） for months. We observed testes, epididymis, ovaries, oviducts and uteri in six species of microbats by the Haematoxylin and Eosin （ H. E） staining of frozen tissue sections and found that sperm storage in five of the 6 species. In addition, we discussed the distribution of bats with different reproductive strategies.
