Patient's question:
Hello everyone, how long can sperm survive after being expelled from the body? When can it combine with an egg cell?Doctor's answer:
Hello: Sperm can survive in the male reproductive tract for up to several weeks, but in semen after ejaculation, they can only live for about 24-72 hours. However, if the temperature is lowered, semen can also be stored for several weeks; if frozen using liquid nitrogen, sperm can even be preserved for a long time.If sperm enter the vagina, uterus, or fallopian tubes, they can survive for several days. However, eggs lose their fertilization ability within 24 to 36 hours after ovulation. Therefore, if you want to conceive, it’s important to make appropriate arrangements for the timing of sexual intercourse.
