Fertility Basics | Complete Fertility

Suarez, A. At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical mucus filters out sperm with poor morphology and motility and as such only a minority of ejaculated sperm actually enter the cervix. In the uterus, muscular contractions may enhance passage of sperm through the uterine cavity. A few thousand sperm swim through the uterotubal junctions to reach the Fallopian tubes uterine tubes, oviducts where sperm are stored in a reservoir, or at least maintained in a fertile state, by interacting with endosalpingeal oviductal epithelium. As the time of ovulation approaches, sperm become capacitated and hyperactivated, which enables them to proceed towards the tubal ampulla.

How pregnancy *actually* happens

When a woman conceives naturally, sperm travel from the vagina through the cervix narrow, lower part of the womb , into the uterus womb , and up into one of the fallopian tubes. If sperm arrive in a tube soon after the release of the egg from the ovary ovulation ; the sperm and egg can meet and unite fertilization in the tube. The cervix naturally limits the number of sperm that enter the uterus. This means that only a small percentage of the sperm in the ejaculate actually make their way into the fallopian tubes. This makes the passage to the fallopian tubes much shorter, and there is a better chance that more sperm will encounter the egg.
