Which women have more chances of producing twins

When a pregnant woman expects not one but two children, the first thing a doctor asks them is if there are similar family stories

According to experts, the legacy is also somewhat responsible for the birth of twins who are born.

If a woman's ovules simultaneously release two eggs during the ovulation period, then the twins are brotherly. They will be, not “, two drops of water”, but like any brother and sister.

Otherwise, identical monosygogue/bignates come from an egg, which is divided into two, and their similarity is incredible.

In very rare cases, semi-identic twins, trilateral or five-man twins, are formed from the same egg, but from different sperm.

What is surprising is that twins are a “phenomen” common to some populations, such as West Africa, and for other populations, like Asians, the occasion when a woman gives birth is very rare.

Furthermore, it has been noted that older women and women who submit to a certain form of fertility treatment are more likely to give birth to twins.

What genes are responsible for bringing twins to life?

A recent study at Amsterdam University Hospital included 1,980 women who had twins and 12,953 women who had a child. Scientists decided to compare their genes.

The results showed that there are two distinct version genes found at higher levels in women who were born twins.

The first is the stimulant hormone (FSH), which helps the ovulating ovulation an egg is discharged after fully matured.

Scientists therefore speculate that if the levels of a woman's stimulating hormone are higher, the chances of releasing two eggs during ovulation are also high.

The second variable is the gene called (SMAD3) and according to the results, it shows how sensitive the ovaries are.

Women can thus produce common FSH levels, but their ovaries are more vulnerable to the hormone, with the result that they release two eggs a month.
