| People often confuse infertility with sterility, which are medically deferent in definition. According to a survey, newly married women who are pregnant within one year after marriage are accounted for about 85%.
Couples who live together without any contraception for more than 2 years (American gynecological textbook and association of sterility define it as 1 years), but haven't gotten pregnant is defined as ¡°sterility¡±.
On the other hand, infertility refers to that women in child-bearing age used to be pregnant, but was not able to keep the baby alive due to spontaneous abortion, premature delivery, or dead birth. Sterility or infertility due to men's factors is called ¡°male sterility¡± or ¡°male infertility¡±, and is generally called infertility. |
