Cervical Mucus Quality, Clomid and Sperm Transport?
Q: I have read information about the maximum amount of time that sperm can survive in fertile cervical mucus (CM). Can you tell me the maximum amount of time sperm can survive in non-fertile CM, like sticky or creamy? Is it only a problem in the vagina and once the sperm makes it into the uterus it can survive for several days? Or, is it that sperm can only make it from the vagina into the cervix if there is fertile CM? A: After ejaculation, sperm have to be able to swim through the cervix to reach the Fallopian Tube where fertilization of the egg occurs.

The “cervical reservoir” of sperm is not an actual pool of fertilizing sperm. Sperm have to get thru CM to get to the Fallopian tube where they are then stored for hours to days until the egg comes. However, the interactions of sperm and
