Many couples engage in sexual activity during their ovulation period. In order to achieve the purpose of contraception, but in fact, the failure rate of this contraceptive method is very high. Because we need to consider not only the female ovulation period, but also the survival time of male sperm in the female body. Normally, eggs survive in the body for about a day. So, how long can sperm survive in the uterus?
Generally, the survival time of sperm in the female body is longer than that of eggs. The survival time of eggs is usually around 24 hours, while the survival time of sperm can reach two to three days, and in some cases even longer. Human sperm can only survive for a few minutes outside the body, while sperm that enter the female sperm body can maintain a relatively vigorous vitality due to the suitable environment,.
After entering the uterus from the cervix, sperm can continue to swim upwards with the help of some uterine fluid. Generally, sperm do not stay in the uterus. After passing through the uterine horn, sperm will reach the isthmus of the fallopian tubes. In addition to blockage in the fallopian tubes, sperm can also pass through both fallopian tubes.
Sperm has a longer survival time in the female body. The fertilization ability can also be maintained for about two to three days. After the egg is released, it can survive for up to one day, and its activity may also change over time. So if both husband and wife want to use contraception or get pregnant, they must calculate the female ovulation period well.
