女子不孕的常見病因是輸卵管堵塞。輸卵管堵塞常常由於感染性傳播疾病。
A common cause of female infertility is the blockage of the Fallopian tubes, often caused by a sexually transmitted infection.

正象上面所提及的那樣，一對夫婦不能生育可能在於男方或女方或雙方。如果醫學檢查證明男方有生育能力，內科醫生將對女方展開一系列的檢查。她可能因為某些先天性缺陷或由於某些感染（尤其淋菌感染）而不孕。這樣的各種感染可能已經永久性地阻塞了她的輸卵管而導致不能受精。有一些不孕的病例，只是無可供受精的卵子，因為她就無排卵。另外一些病例受精確實發生過，但是受精卵不能附著到子宮內膜裏。還有一些例子，受精和植入都正常，只是隨後的早期自發性流產而導致妊娠失敗。這種病例的病因可能是子宮或子宮頸不正常。有一些女子的子宮頸黏液栓太稠，以至於不能被精子穿透；還有一些女子的子宮頸液或陰道液不利於精子生存而最終導致精子死亡。偶爾，有的女子體內會產生抗體，並被分泌到陰道內，對所有的精子或對特定男子的精子產生免疫作用，這也是女子不孕的原因。 |

Infertility in Women
|
|
As mentioned above, the cause of a couple's infertility may lie with the man or the woman, or both. If medical tests prove the man to be fertile the examining physician will start a new series of tests on the woman. She may be sterile because of certain congenital defects, or as a result of certain internal infections especially gonorrhea. Such infections may have led to a permanent blocking of the Fallopian tubes, thus making fertilization impossible. In some cases of infertility, there simply is no egg to be fertilized because there is no ovulation. In other cases, fertilization does take place but the fertilized egg invariably fails to attach itself to the uterine wall. In still other instances, both fertilization and implantation occur, only to be followed by early spontaneous abortions (miscarriages). The reason for this may be some abnormality of the uterus or the cervix. In certain women, the cervical mucus is too thick to be penetrated by sperm; in others, the cervical or vaginal fluids are hostile to the sperm and kill it. Sometimes women develop antibodies which appear in the vagina and produce an immunity to all sperm or to the sperm of a particular man. |
