體內受精(英語: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]。在這種受精形式下,精子可利用在液體中運動的能力,游向卵子並與其結合。進行體內受精的動物包括哺乳類爬蟲類鳥類

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]

體內受精的方式[编辑]

於雌性動物體內發生的受精可透過以下以種方式進行:[6][7][8]
