Babies are made through a process that typically involves the fertilization of an egg by a sperm. Here's a simplified overview of how this process works:
-
Ovulation: In individuals with a uterus, an ovary releases an egg (ova) during a process called ovulation, which usually occurs once a month.
-
Fertilization: During sexual intercourse, sperm from a male can enter the female's body and swim through the cervix and uterus to reach the egg in the fallopian tube. If a sperm successfully penetrates the egg, fertilization occurs.
-
Zygote Formation: Once the sperm fertilizes the egg, it forms a single cell called a zygote.
-
Cell Division: The zygote begins to divide and develop as it travels down the fallopian tube toward the uterus.
-
Implantation: Once it reaches the uterus, the developing cluster of cells (now called a blastocyst) implants itself into the uterine lining, where it continues to grow and develop into an embryo.
-
Development: Over the course of about nine months, the embryo develops into a fetus, and eventually into a baby, ready for birth.
It's also worth noting that this is a biological process, and there are additional methods of conception, such as in vitro fertilization (IVF), where fertilization occurs outside the body before implantation.
