All results above indicated that:The expression of ERβand p-ERβin mouse ovary at oestrous cycle and in early gestational period changed regularly, it showed that ERβand p-ERβhad important effects to ovaries development, ovarian follicles groth, oocyte maturation and form corepus luteum in female mouse ovary during oestrous cycle and in early gestational period.

以上结果表明：ERβ及其磷酸化形式——p-ERβ在小鼠发情周期以及妊娠早期卵巢中表达有规律性的变化，揭示ERβ与p-ERβ在雌性小鼠发情周期及妊娠早期，对卵巢发育、卵泡生长、卵母细胞成熟和黄体形成有重要的作用。

The mate choice of Brandt′s voles Microtus brandti was investigated in the laboratory to study the mating system of this species. It was found that the female voles spent significantly more time visiting the partners than the strange males, but the male voles did not show any preference of the partners to the strange females. A female vole showed no difference in the copulatory behavior between an unfamiliar male and a familiar male which had copulated with her for 15 minutes, but she visited and fought the unfamiliar male significantly more than the familiar male. A male vole significantly preferred visiting and mating with an unfamiliar oestrous female to a familiar female which had copulated with him for 15 minutes.

在实验室通过布氏田鼠对配偶与陌生异性鼠、已交配和未交配异性鼠、熟悉和陌生异性鼠三种情况下配偶选择的实验研究，结果表明：雌性布氏田鼠对配偶的选择显著地要多于陌生雄鼠；虽然对陌生和熟悉雄鼠选择差异不显著，但对陌生鼠的选择强度要高于熟悉雄鼠；同时对已交配和未交配雄鼠的选择无显著差异。
