It starts to develop in utero and completes most of its development by the mid twenties, between 21 to 25.

Seeds develop from the ovules in the female plant, after they have been fertilised by the pollen from the male parent plant. This is termed 'sexual reproduction', as seeds contain the genes of both the male and female parent, and usually both male and female flowers are required to produce seeds. Sometimes, the male and female flowers are from separate plants, sometimes they are from the same plant, and sometimes a flower may be fertilised by its own pollen. The ovules are the embryos from which the seed will develop. At the time of fertilisation, they are very small compared to the mature seed. Without being fertilised (in most cases), the ovules will not develop into seeds, any more than pollen can. So in order to develop into seeds, the ovules must first be fertilised.
Cuz they are, ok
It has been reported that most women develop about 400 eggs in their ovaries by the time of menstruation. These wouldn't be embryos until they have been fertilized.
Oviparous -- reproduction by eggs that develop outside the body -- birds, most reptiles Viviparous -- reproduction via live birth where offspring develop inside the mother's body -- human, most mammals
Monotremes- are mammals that lay eggs instead of giving birth to live young like marsupials and placental mammals Oviparous- animals are animals that lay eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians and reptiles, all birds, the monotremes, and most insects and arachnids. Ovoviviparous- animals develop within eggs that remain within the mother's body up until they hatch or are about to hatch. This strategy of birth is known as ovoviviparity. It is similar to vivipary in that the embryo develops within the mother's body. Unlike the embryos of viviparous species, ovoviviparous embryos are nourished by the egg yolk rather than by the mother's body. However, the mother's body does provide gas exchange. Viviparous- is an animal employing vivipary: the embryo develops inside the body of the mother, as opposed to outside in an egg (ovipary). The mother then gives live birth.
Most mammals are placental mammals: they develop in a placenta before birth. Marsupials also develop in a placenta, but they are delivered much earlier and the placenta is less developed. Monotremes develop within an egg, which is kept inside the mother for some time before it is laid. It hatches several days later.
Most rays are ovoviviparous, bearing live young in "litters" of five to ten. The female holds the embryos in the womb without a placenta. Instead, the embryos absorb nutrients from a yolk sac, and after the sac is depleted the mother provides uterine milk
Among the mammals - monotremes Among birds - all of them Among fish - most of them Among reptiles - most of them Among insects - most of them Egg laying is common to all species of birds and most reptiles, though several species of snakes and lizards are viviparous. Most fish and amphibians are oviparous as well. Among mammals, only the platypus and four species of echidna lay eggs. There is a third mode of reproduction, called "ovovivipary" in which embryos develop inside eggs that are held within the mother's body, until they are ready to hatch. The scientific term for an animal that lays eggs is oviparous.
