Twins occur in the same family due to genetic predisposition but there are some external factors that may contribute to a twin pregnancy, such as taking a medication that stimulates ovulation or through in-vitro fertilization.
When the man has a twin brother, this does not mean that his wife will have twins, because the genetic factor is totally dependent on the woman.
Probability of getting pregnant of twins
Not every woman can get pregnant with twins naturally, because the main factor in making that happen is that she is the twin of another brother or sister. In this case, the woman will mature 2 eggs at one time, and will have twin children, but not identical.
The chances of having identical twins are the same for all women, because in this case, initially there was only one egg that was fertilized by a sperm, but in the first hours of conception, it split into 2, giving rise to two identical, non-identical being influenced by genetics, occurring by chance.
Pregnancy Remedies for Twins
Remedies, like Clomiphene, are not only prescribed for the woman to conceive of twins. This type of medicine is prescribed to stimulate ovulation during a fertility treatment that lasts for many months and should always be directed by specialists in human reproduction.
Tips for getting pregnant with twins
There are a few tips that can help increase the chances of having two identical but different babies at once, such as:
- Getting pregnant before the age of 35, between the ages of 18 and 30, the eggs are healthier, with better conditions to maintain a healthy gestation until the end;
- Getting pregnant near menopause, in the 40's and 50's, because at this stage the increase in estrogen can cause the body to release more than one egg at a time;
- Get treatment for pregnancy, with medications or IVF;
- Try to get pregnant as soon as you stop taking the contraceptive because in the first 3 cycles the body is still adjusting and there are more chances of releasing more than one ovule;
- Eat more yams and sweet potatoes because this helps the woman to ovulate more and better.
Facts not proven by science
Taking folic acid does not guarantee the pregnancy of twins because this is a dietary supplement indicated for all women who are trying to conceive or who are already pregnant to protect the baby's nervous system.
Eating more dairy products like milk, yogurt, butter and cheese are good sources of calcium, but it has no scientific proof that it can interfere with ovulation;
Sexual positions also do not interfere with the ability to conceive of twins because the most important thing is for the woman to have 2 eggs at the same time in the tubes and this can not be achieved during sexual contact, since it is not because more sperm arrive than the woman will pregnant with twins.
How is the pregnancy of twins?
Twin pregnancy is considered a risky pregnancy because there is a greater risk of premature birth and eclampsia, which is raising blood pressure in a dangerous way.
Because of this, the expectant mother of twins should have some special care during pregnancy such as attending all prenatal appointments and having a balanced diet. Sometimes the obstetrician indicates that the woman needs to be rested around the 30 weeks of gestation so that the babies can grow and gain enough weight to be born healthy.
Difference between univitelinos twins and bivitelinos
There are two types of twins, the same ones that are the univitelinos, and the different twins, who are the bivitelinos.
In univiteline twin pregnancies babies share the same genetic information, possessing only slight differences from one another, such as fingerprint, for example. In this case, the ovum was fertilized by only one spermatozoon and the egg formed divides in two, giving rise to 2 identical babies.
But in the pregnancy of twin twins, babies are different, being a boy and a girl. In this case, 2 ova were maturated and fertilized by 2 different spermatozoa.
In this way, the twins can be:
- Univitelinos: They share the same placenta and are equal
- Bivitelinos: Each one has its placenta and they are different
Although uncommon, it is possible for the woman to have a new ovulation after a few days of fertilization, becoming pregnant with twins with days or weeks of difference between them. In this case the twins will be bivitelinos.
