Understand the survival time of egg cells and grasp the best time to have sex

How long does an egg cell survive? This is a question that couples planning to have a baby are more concerned about, because the survival time of the egg is closely related to whether fertilization is successful. The chance of getting pregnant during ovulation is much higher. So let's learn about the common knowledge about the survival time of an egg cell.

Egg survival time

For a woman, the possibility of pregnancy begins with the two ovaries, small, oval-shaped organs attached to either side of the uterus that are filled with eggs. The egg can survive for 1-2 days, and its fertility ability is strongest within 24 hours after ovulation. Sperm can survive for 2 to 3 days after entering the female reproductive tract, so it is easiest to get pregnant when having sex during the ovulation period, and the further away from the ovulation period, the lower the chance of getting pregnant. The 5 days before and 4 days after ovulation, a total of about 10 days, are the fertile period, and the rest of the time is a relatively safe period. During the ovulation period, you can have sex once a day.

The egg does not stay still after being released, waiting for the arrival of sperm.

After the egg is discharged from the follicle, it usually takes 8 to 10 minutes for it to be absorbed into the fallopian tube cavity by the fimbria of the fallopian tube and reach the connection point between the ampulla and the isthmus of the fallopian tube. The egg then stays here, waiting for the arrival of sperm. Generally, fertilization occurs within 12 hours after ovulation, and the entire fertilization process takes about 24 hours.

How long does it take for sperm and egg to combine?

Each time a man discharges about 200-400 million sperms, most of which are discharged from the vagina along with the semen, and a small number of sperms move forward by swinging their tails, passing through the cervical canal and uterine cavity, and finally reaching the final destination - the ampulla of the fallopian tube, where they wait to combine with the egg. It takes 1-1.5 hours for sperm to be discharged into the fallopian tube and wait for the egg to combine. During intercourse, a man discharges about 200 to 400 million sperm each time, however, most of the sperm are discharged from the vagina along with the semen. Because the cervical mucus is alkaline, it is conducive to sperm activity. A small number of sperm rely on the swinging of their tails to move forward and quickly swim to the cervical canal. The sperm releases protein-lytic enzymes to dissolve the cervical mucus; the uterine contraction and fallopian tube peristalsis caused by sexual intercourse accelerate the movement of sperm. The sperm swims to the ampulla of the fallopian tube, where they wait to combine with the egg. The fastest time for sperm to reach the fallopian tube from the vagina is only a few minutes, the latest is 4-6 hours, and usually 1-1.5 hours.
