In the European badger Meles meles L., the progesterone profile during the gestational phase shows two successive periods. The first, corresponding to implantation could be due to pituitary stimulation and seems not to have any relation with embryos. The second seems to be due to the presence of the placenta. Indeed, after hysterectomy the levels of plasma progesterone are significantly lower.
在欧洲獾（Meles meles L.）中，妊娠期的孕酮水平呈现出两个连续的阶段。第一个阶段对应着床期，可能是由于垂体刺激引起的，似乎与胚胎没有任何关系。第二个阶段似乎是由于胎盘的存在。实际上，子宫切除术后血浆孕酮水平显著降低。
