Hostile Uterus

A hostile uterus is an outdated term used to describe either insufficient or poor-quality cervical mucus that is unfriendly to the movement of sperm.

As a result, sperm loses the ability to travel through a woman’s cervix and is likely to die prior to reaching the fallopian tube to fertilize an egg.

So-called hostile cervical mucus is not ideal for facilitating pregnancy and is a cause of subfertility.

A hostile uterus may also be called cervical hostility. Because the cervix is the lower part of the uterus, the two terms have been used interchangeably to describe this condition.
