Twins in IVF
IVF is a method to help infertile couples achieve their reproductive aspirations through assisted reproductive technology. Twins sometimes occur during IVF. So what is the probability of twins in IVF? The following will elaborate on the factors of age, embryo transfer strategy, hormone therapy and the actual situation of the hospital.
Age factor
The age of female is one of the important factors that affect the probability of twins in IVF. With the increase of age, female fertility gradually decreases. According to statistical data, the incidence of twins in IVF infants under 30 years old is low, about 15%. However, in the age group above 35, the incidence of twins will increase significantly, even more than 30%.
The influence of age on the probability of twins is mainly because women may release multiple eggs at the same time in one ovulation cycle. This is because as women grow older, their ovarian function declines and hormone secretion is unbalanced, which may lead to the simultaneous release of multiple eggs during ovulation. This provides the possibility of twins.
In addition, the influence of age on the twin probability is also related to the embryo transfer strategy in the process of in vitro fertilization, which will be introduced in detail next.
Embryo transfer strategy
The success rate of IVF is closely related to the quality of embryos. In one IVF cycle, multiple fertilized eggs are usually cultivated in the laboratory, but doctors will not transplant all embryos back to the uterus. The aim is to reduce the incidence of multiple embryo pregnancies.
During embryo transfer, doctors can choose to transfer a single embryo back to the uterus or transfer multiple embryos at the same time. Compared with single embryo transfer, multiple embryo transfer has a higher incidence of twins. According to statistical data, in the case of multiple embryo transfer, the incidence of twins can reach more than 50%.
However, it should be noted that multiple embryo pregnancy also has certain risks, including premature delivery, low birth weight and other problems. Therefore, when carrying out embryo transfer strategies, doctors need to make trade-offs and choices according to the specific conditions of patients.
hormone therapy
Hormone therapy is one of the common adjuvant treatments in IVF. Hormone therapy can help regulate women's ovarian function, promote ovarian ovulation and increase the probability of pregnancy.
However, hormone therapy may also increase the risk of multiple pregnancies. The use of hormone can increase the number of ovarian ovulation, thus increasing the probability of twins. Therefore, when conducting hormone therapy, doctors need to weigh the potential risk of multiple pregnancy, and adjust and monitor according to the specific situation of patients to ensure the safety of mothers and infants.
Actual situation of the hospital
The twins probability of IVF is also affected by the actual operation of the hospital. The operation process, technical level and the ability to interpret statistical data of different hospitals may have an impact on the incidence of twins.
Some professional IVF hospitals may have stricter embryo transfer strategies to reduce the risk of multiple embryo pregnancy. At the same time, the hospital's technical level and equipment conditions will also have an important impact on the success rate of IVF surgery.
Therefore, when selecting IVF hospitals, it is necessary to comprehensively consider the hospital's professional level, equipment conditions, postoperative nursing services and other factors, and avoid blindly pursuing low prices and quick success, so as to ensure the health of oneself and the baby.
Summary
The twin rate of IVF is affected by many factors, including the age of women, embryo transfer strategy, hormone therapy and the actual situation of hospitals. Age is one of the main factors that affect the probability of twins. The probability of twins will increase with age. Embryo transfer strategies and hormone therapy can increase the incidence of twins, but may also increase the risk of multiple pregnancies. The actual operation and technical level of the hospital will also have an impact on the probability of twins. Therefore, before IVF surgery, it is necessary to fully understand the situation of the hospital, select appropriate embryo transfer strategies, and carry out hormone therapy according to the doctor's recommendations to improve the success rate and ensure the safety of mothers and infants.
