What factors affect the chances of having twins?
The chances of a woman having identical twins are about the same for everyone, as identical twins do not tend to run in families. This is considering identical twins come from a single fertilized egg splitting in two and this is a random, rare issue.
Fraternal twins, on the other hand, can be genetic. Congenial twins come up from two dissever eggs being fertilized by two sperm. Typically women merely release ane egg each cycle but women who excogitate fraternal twins take released two. This is why fraternal twins can just exist genetically connected through the mother, significant the male parent's genetics have goose egg to do with twinning.
Releasing more than 1 egg in a cycle is chosen hyper-ovulation and is controlled by certain genes. Women who conceive fraternal twins usually have loftier levels of these genes, which makes sense.
So who is more than likely to conceive fraternal twins? Your chances of having twins depend on vi factors:
ane. Body type

Those same women were more than likely to have opposite sexual activity twins than same sexual practice twins as well. Researchers are withal unsure why this is the instance.
2. Ethnicity and location
On the surface it appears that ethnicity plays a office in the chances of having twins, yet location seems to accept a large part too.
The Yoruba tribe of Nigeria has the highest rate of twins at 45–fifty twin sets (or 90–100 twins) per 1,000 live births, notwithstanding beingness of Nigerian decent and living elsewhere doesn't show the same correlation to twin births.
In Central Africa in that location are xviii–thirty twin sets (or 36–60 twins) per 1,000 live births. Due north America and Europe (and caucasians in full general) have intermediate rates of 9-sixteen twin sets per one,000 live births Latin America, Southward Asia, and Southeast Asia (and hispanic and asian ethnicities in full general) accept the lowest rates of 6–nine twin sets per 1,000 alive births.
The difference in chances of having twins between geographic locations (more ethnicity) begs the question of whether climate, diet, or lifestyle have more to practice with the chances of having twins than annihilation else.
3. Nutrition

4. Maternal Historic period
Older woman tend to have a higher run a risk of fraternal twins. Women over 35 tend to produce more than FSH than younger women and women with higher levels of these hormones are more than likely to take twins.
The increase in FSH levels also shows failing fertility, which means they are less probable to go pregnant, but more likely to accept twins if they happen to conceive.
5. Number of Pregnancies
The more pregnancies that a woman has had increase her chances of having twins. This could be a simple instance of numbers. The more pregnancies yous have the college your chances of having twins.

Fertility drugs increase the odds of you releasing several eggs at the same time by stimulating your ovaries. These kinds of drugs increase your chances of having twins or multiples to x% or higher, up to every bit much as thirty%.
vii. Breastfeeding during conception
