What is Fertilization?
Fertilization is the fusion of a sperm cell with an egg cell, resulting in the formation of a zygote. This process marks the beginning of the development of a new organism.Steps of Fertilization
- Release of the egg: During ovulation, an egg is released from the ovary and enters the fallopian tube.
- Introduction of sperm: Sperm are introduced into the female reproductive tract through sexual intercourse.
- Union of sperm and egg: If a sperm cell successfully penetrates the egg cell, their genetic material combines to form a zygote.
- Implantation: The zygote travels down the fallopian tube and implants itself in the lining of the uterus, where it begins to develop into an embryo.
Factors Affecting Fertilization
- Timing: Fertilization is most likely to occur if sexual intercourse takes place around the time of ovulation.
- Sperm health: The health and viability of the sperm cells can influence the likelihood of successful fertilization.
- Uterine environment: The condition of the uterus and the fallopian tubes can impact the chances of successful implantation after fertilization.
