It is very meaningful for a couple to have children and raise a life because they love each other. The combination of sperm and egg gives birth to a small life. This little life slowly took root and sprouted in my mother's belly until birth. But everyone still feels very mysterious about the process of sperm and egg binding. Next, let's take a look at the fertilization process of sperm and egg.
1. During sexual intercourse, men ejaculate about 200-400 million sperm each time. After the male sperm enters the female vagina, most of the sperm are discharged from the vagina along with the semen. Because cervical mucus is alkaline, it is conducive to sperm activity. A small portion of sperm rely on the movement of their tails to move forward and quickly swim towards the cervical canal, releasing proteolytic enzymes to dissolve cervical mucus; The uterine contractions and fallopian tube peristalsis caused by sexual intercourse accelerate the movement of sperm; The peristalsis of the fallopian tube muscle layer, the oscillation of mucosal cilia, and the flow of fallopian tube fluid secreted by mucous cells lead to the movement of sperm from the uterine cavity to the ampulla of the fallopian tube.
2. At the final destination - the ampulla of the fallopian tube, waiting to combine with the egg. The fastest time for sperm to reach the fallopian tubes from the vagina is only a few minutes, the latest is 4-6 hours, and generally 1-1.5 hours. During the process of sperm advancement, they are obstructed by cervical mucus and engulfed by white blood cells in the uterine cavity, resulting in only a few dozen to one hundred to two hundred reaching the fallopian tubes. Sperm still needs to undergo a period of incubation in the female reproductive cavity before fertilizing the egg. After undergoing morphological, physiological, and biochemical changes, it has the ability to fertilize. This process is called sperm capacitation. Healthy sperm and eggs are both prerequisites for nurturing a healthy baby. Data shows that nearly 70% of expectant parents have no knowledge of sperm and eggs, let alone the control of ovulation period. In fact, to improve the fertility rate, accurately calculating a woman's ovulation period is the key first step.
The above is the encyclopedia introduction about the fertilization process of sperm and egg. In short, due to the cyclical nature of ovulation in women, the production of sperm is relatively easier. Therefore, accurately calculating the ovulation period and ensuring the arrival of sperm at the freshest and healthiest time of the egg is a prerequisite for nurturing healthy embryos. I hope this article can be helpful to everyone.
