How are two or more babies formed?

Question

video links are welcomed

Answer 1

when p***s found v****a, it formed :)

Answer 2

You mean multiples?

Its pretty simple, and has two ways of occuring:

1. The ovary releases two or more eggs and the sperms unite with these eggs. The babies from this kind will be fraternal (not the same) and will have separate placentas etc.

2. The woman releases one egg, and one sperm unites, but the cell divides, and creates more, usually the cell only splits to 2, resulting in twins. In this case the babies will be identical and share the same placenta etc.

In other cases of triplets and quads, these are normally resulting in the use of IVF. With IVF (in-vitro fertilisation) many embryos are implanted to ensure a pregnancy as some will normally die.

Anyway, hope that helps

BTW i have fraternal twin baby sisters lol.

Answer 3

Twins can be monozygotic (identical) where one sperm fertilises an egg wheich then splits and develops separately. They are identical because they inherited the same genes from the same sperm and egg.

Alternatively, fraternal (non-identical) twins occurs when two eggs are released and are fertilised by different sperms. They can be of opposite sexes since the sperm carries the X or Y chromosome determining if the fotus will be male or female. Fraternal twins are no more likely to be alike than other siblings, it is simply two pregnacies occuring at the same time.

Less frequently three or more eggs may be fertilised leading to triplets or other multiple births.

IVF (In Vitro Fertilisation) treatment for couples having trouble conceiving leads to multiple births.

1. The female is given hormonal treatment to bring about multiple ovulation (release of eggs from the ovary).

2. The eggs are collected using a fine tube.

3. Eggs are added to sperm from the partner or donor in a nutrient medium and allowed to incubate at 37oC for several days.

4. The pertri dish is examined under the microscope to look for presence of embryos (a tiny ball of cells formed by division of fertilised eggs)

5. Several embryos are implanted in the womb of the female at the time of the month when her womb is most developed for a potential pregnancy.

6. Unused embryos are frozen for use if the first attempt at IVF is unsuccessful.

If two or more of the implanted embryos successfully implant in the female's womb then it will lead to multiple births.

Hope this helps!
