Gestation.
Period of time between fertilization and birth of an animal. Commonly called pregnancy.Gestation is pregnancy, carrying in the womb.Gestation is the process of carrying or being carried in the womb between conception and birth. Some animals gestation period lasts up to 113 days.
The process of preventing fertilization of eggs is called contraception or birth control. Examples of contraception include the birth control pill, Depo Provera injection, the coil and condoms.
Internal because they give birth and not lay eggs. If they lay eggs, they would be like a chicken. ~Savannah B.
all animals have eggs, but it depends their fertilization development type (which is either internal or external). Humans are mammals, and all mammals give live birth unless it is a monotreme, which lays eggs.
Giraffes have internal fertilization. Giraffe gestation lasts 400 to 460-days. The mother gives birth standing up to a single calf. The mother then grooms the newborn and helps it stand up.
In some species there is external fertilization. In other species there is live birth. Live birth requires internal fertilization.
Pregnancy is the process of carrying a fetus for nine months. Birth is the process of delivering a baby. Conception is when the egg is fertilized.
Most mammals use sexual reproduction, where fertilization is internal, and give live birth.Some mammals are oviparous (egg laying) mammals called monotremes, namely platypuses and echidnas -- the young are not born live but are nursed after they hatch.Pouched mammals and placental mammals give birth to tiny young ones, so are called viviparous.Sexual intercourse
The time period from fertilization to birth is called gestation.
Hormonal forms of birth control (the Pill, Depo-Provera shots, the Nuva ring, the Patch) prevent eggs from being released, and therefore prevent fertilization from occurring. Condoms (male and female) also prevent fertilization from occurring if they are used properly. The IUD prevents implanation after fertilization by a process not fully understood.
This form of birth control does not interfer with fertilization but does inhibit inplantation
Mammals give birth to live young
