The most crucial step in nurturing the next generation is fertilization, which is the earliest beginning of any life. Sperm is produced through the male testicles under the stimulation of androgens, while eggs are produced by the female ovaries under the action of estrogen and progesterone. Can sperm and eggs develop into individuals?
Sperm and egg cannot be fertilized in any environment, and if they cannot be fertilized, they cannot develop into individuals. Generally, sperm and eggs can only develop into fertilized eggs in the female uterine environment. Although there is currently technology for artificial in vitro fertilization, it actually simulates the internal environment of the female body.
What are the necessary conditions for sperm and eggs to develop into individuals besides having a suitable environment?
One is the appropriate meeting time. Sperm is most active within 48 hours of entering the female body. Women usually only lay eggs once per menstrual cycle, so only when the egg cell and sperm meet with good activity can they combine to form a fertilized egg.
The second is high-quality cells. After each ejaculation, countless sperm enter the female body, and only the highest quality sperm can quickly reach the position where they are most likely to bind with the egg cell. Most sperm are actually just running along during this process; Although eggs are normally produced during each menstrual cycle, not every egg produced has the ability to develop into a fertilized egg. Therefore, only when both the egg cell and sperm are high-quality cells can there be a possibility of developing into an individual.
