Answer:
Reproduction in humans involves the union of a sperm cell from a male and an egg cell from a female. Here's a simplified overview of the process:
1. **Gamete Production**: In males, specialized cells called sperm are produced in the testes through a process called spermatogenesis. In females, eggs (ova) are produced in the ovaries through a process called oogenesis.
2. **Fertilization**: During sexual intercourse, sperm are ejaculated into the female's vagina. The sperm then swim through the cervix and into the uterus, where they may encounter an egg if it has been released from the ovary. Fertilization occurs when a sperm successfully penetrates the egg.
3. **Zygote Formation**: When the sperm fertilizes the egg, it forms a single cell called a zygote. This cell contains genetic material from both the mother and father.
4. **Implantation**: The zygote begins to divide and forms a blastocyst. The blastocyst travels down the fallopian tube and eventually implants itself into the lining of the uterus. This is where it will develop into an embryo and, later, a fetus.
5. **Embryonic Development**: Over the next nine months, the embryo undergoes a series of developmental stages, ultimately becoming a fully formed baby. This process involves the growth of various organs and systems.
6. **Childbirth**: At the end of the pregnancy, the baby is born through the mother's vaginal canal or via a surgical procedure like a Cesarean section (C-section).
It's important to note that this is a simplified explanation, and the reproductive process is complex and regulated by hormones and various physiological factors. Additionally, not all pregnancies result in a successful birth, and there can be complications at various stages of reproduction.
Verified answer
When male and female engage in sexual intercourse, and the male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (pronounced: ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.
