答案

答案:C

题目分析:A、受精作用发生在输卵管,受精卵不断进行分裂,逐渐发育成胚泡,胚泡移动到子宫中植入子宫内膜,这是怀孕,B、胎儿通过胎盘、脐带与母体进行物质交换,D、月经是子宫内膜脱落的现象,输卵管结扎后,并不影响产生月经,故A、B、D都不符合题意。

C、男性的精囊、输精管、睾丸、阴茎等构成了男性的生殖系统,女性的卵巢、输卵管、子宫、 * * 等构成了女性的生殖系统,其中男性产生生殖细胞--精子的器官是睾丸,同时睾丸也可以分泌雄性激素,又属于内分泌器官,是男性的主要生殖器官,女性产生生殖细胞--卵细胞的器官是卵巢,同时卵巢也可以分泌雌性激素,又属于内分泌器官,是女性的主要生殖器官。
