Twins are mainly divided into identical twins and fraternal twins. Identical twins are formed by dividing the same fertilized egg. They have the same genetic material and the same sex. This formation mechanism has a certain

The randomness of

. Fraternal twins are formed by the union of two different eggs and two different sperm, each with its own genetic material, which may be the same sex or different. Then

Is

there only one way for ordinary people to want twins? What are the risks of IVF twins that need special attention? Next, let's discussthe factors of having twins:

1. Age factor

Older women are relatively more likely to have twins. Although a woman's chances of being infertile increase with age, advanced age does increase the chance of having twins if she can successfully conceive.

In most cases, women only eject one mature egg a month. As you age, the probability of irregular ovulation cycles occurring in women will be higher than in the past, which may lead to a

Evacuation of two eggs at the same time in a month increases the chance of having twins.

But we do not encourage deliberately late childbearing in order to have twins. Because having twins is only a certain probability event, it may not be possible to encounter it even if you age. Moreover, the age will increase. Will it increase?

Risk of pregnancy, miscarriage, and fetal abnormalities.

2. Factors of ovulation inducing drugs

Some women have patent fallopian tubes, but cannot conceive naturally due to problems such as irregular ovulation or ovulation disorders. In such cases, ovulation can be assisted by giving ovulation-inducing drugs.

Under the action of drugs, two mature follicles may sometimes be expelled at the same time, which may lead to twins.

I would like to remind all women that if they face infertility problems, they should not be too anxious. They can go to the hospital for examination first. The key is to find the cause and then provide symptomatic treatment. It is not necessary to enter

IVF, auxiliary methods such as monitoring ovulation, recanalization of fallopian tubes, outpatient discharge promotion, and artificial insemination can also help pregnancy.

3. IVF Factor

IVF does have a higher chance of twins than natural pregnancies. However, single embryo transfer is a method long advocated by the world's reproductive authority and is currently the main transfer strategy.

The happiness brought by twins may be doubled, but the risks they face are more than doubled. In terms of abortion rate, the incidence of twin abortion is 2 to 3 times higher than that of single pregnancies, and the premature delivery rate is even higher than that of single pregnancies.

7 to 10 times.

Therefore, in order to ensure safety during pregnancy, please follow the doctor's arrangements and try to transfer an embryo as much as possible. However, it is true that not everyone is required to undergo a single embryo transfer. The doctor will determine the patient's age

Hormone levels, endometrial conditions and systemic conditions were comprehensively evaluated. For example, if some women fail totransplant multiple times, doctors will recommend transplanting two embryos based on specific circumstances to increase the risk of pregnancy

Chance.

In short, the conclusion is that the probability of twins born in IVF will be higher than that of natural pregnancy, but twins are not our ultimate goal. We also hope that every woman can get pregnant smoothly and give birth safely.
