体内受精(英语:Internal fertilization)是指女性体内有性生殖过程中卵子精子细胞的结合。体内受精不同于体外受精,给雌性带来更多的生殖控制[1]。在这种受精形式下,精子可利用在液体中运动的能力,游向卵子并与其结合。进行体内受精的动物包括哺乳类爬虫类鸟类

大多数通过体内受精繁殖的分类群雌雄异体[2]:124-125。当前在哺乳动物爬行动物和某些其他动物群体中,这是通过交配来实现的,即将一个侵入式器英语intromittent organ引入阴道泄殖腔[3][4]。大多数鸟类使用泄殖腔吻,两只动物在传递精子时将泄殖腔压在一起.[5]

体内受精的方式 编辑

于雌性动物体内发生的受精可透过以下以种方式进行:[6][7][8]
