Normal fertility requires the production of enough healthy sperm by the male and viable eggs by the female, successful passage of the sperm through open ducts from the male testes to the female fallopian tubes, penetration of a healthy egg, and implantation of the fertilized egg in the lining of the uterus (see reproductive system). A problem with any of these steps can cause infertility.

正常生育有赖于男方产生出足量的健康且活动的精子,以及女方要有能生育的卵。首先从男方睾丸产生的精子要经过射精管成功进入女方阴道,穿过子宫进入输卵管,其中一个精子要能穿入一个正常的卵,而后受精卵要能植入子宫内膜。在这些步骤当中如有任何差错皆能导致不育。
