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.
How long does it take sperm to reach the cervix?
How long does it take sperm to reach the cervix? Within a few minutes of ejaculation, sperm will arrive at the cervix. Some women have been told to lay on their backs for 30 minutes to an hour after ejaculation to help the sperm reach the cervix, but that is not necessary.
What prevents sperm from entering the cervix?
The protected sperm with the greatest motility travel through the layers of cervical mucus that guard the entrance to the uterus. During ovulation, this barrier becomes thinner and changes its acidity creating a friendlier environment for the sperm. The cervical mucus acts as a reservoir for extended sperm survival.
