According to Chapter 4; page 120 of this weeks reading, "Men have nocturnal erections every 90 minutes or so as they sleep. They generally occur during REM (rapid eye movement) sleep, which is associated with dreaming."
The process of uniting an egg with a sperm is called fertilization. It occurs when a sperm cell penetrates the outer layer of an egg cell and fuses with the egg's nucleus, forming a zygote. This marks the beginning of a new organism's development.
The initial event in development is fertilization, where a sperm cell fertilizes an egg cell to form a zygote. This marks the beginning of the development of a new organism.
Men have testes because they produce sperm, which is necessary for the fertilization of ova. This fertilization results in the development of a fetus.

Fertilization is the fusion of a sperm and egg to form a zygote, while embryo development involves the growth and differentiation of cells in the zygote to form an embryo. Fertilization marks the beginning of development, while embryo development encompasses the processes that lead to the formation of a multicellular organism.
It's called, fertilization... I'm pretty sure its spelled correctly.
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
Elephants have internal fertilization, where the male transfers sperm into the female's reproductive tract. The sperm fertilizes the egg inside the female's body, leading to the development of the embryo. Elephants have a long gestation period of around 22 months.
Rabbits reproduce through internal fertilization. During mating, the male rabbit (buck) deposits sperm into the female rabbit's (doe) reproductive tract. Fertilization occurs when the sperm fertilizes the doe's eggs, leading to embryo development.
Fertilization
Fertilisation is when the sperm cell and the ova fuse together to form a zygote.
That process is the fertilization. It is the joining of sperm and ovum.
