Traveled path of sperm through vagina

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. Sperm may be guided to the oocyte by a combination of thermotaxis and chemotaxis. Motility hyperactivation assists sperm in penetrating mucus in the tubes and the cumulus oophorus and zona pellucida of the oocyte, so that they may finally fuse with the oocyte plasma membrane.

Egg meets sperm (article) | Embryology | Khan Academy

From the vagina, through cavity of cervix and uterus,then through fallopian tube where the sperm meets the egg in ampulla, a part of fallopian tube. Once ejaculated out of the penis, sperm travels up the vagina. It then goes through the cervix, which is the entrance to the uterus. Once inside the uterus, it goes towards the fallopian tubes in search of an egg. If no egg is found, it dies within 48 hours.

Understanding the process of how pregnancy occurs can be beneficial both for those who are trying to become pregnant, and those who wish to avoid pregnancy. For those that wish to avoid pregnancy, we highly recommend using both a barrier method of birth control , such as a condom , and a hormonal method, such as birth control pills. Using a condom properly will also help prevent the spread of sexually transmitted infections STIs.
