Does IVF hormone cause multiple births
IVF refers to the process of implanting the fertilized egg into the mother's uterus through in vitro fertilization technology. In the process of IVF, hormone therapy is often used to promote and regulate ovarian function to increase the probability of pregnancy. However, some people worry that the hormones used in IVF will lead to multiple births. This article will discuss whether IVF hormone can lead to multiple births from the aspects of physiological principles, hormone use methods, actual clinical data and some risk factors.
Physiological principle
In the case of natural pregnancy, a woman's ovary usually discharges only one egg per month, which is a natural protection mechanism to ensure that only one fetus is conceived in the uterus. However, in order to improve the success rate of IVF, hormone therapy is used to promote the development of multiple ovarian follicles and ovulation. Therefore, in the process of IVF, multiple eggs may be released at the same time, leading to an increased risk of multiple births.
However, it is worth noting that not all IVF babies using hormone therapy will lead to multiple births. Whether or not multiple births occur depends on such factors as the type and dosage of hormones and individual differences.
Hormone usage
Hormones commonly used in IVF include ovulatory stimulating hormone, progesterone and human chorionic gonadotropin. These hormones increase ovulation rate and pregnancy probability by controlling ovarian function.
In order to reduce the risk of multiple births, doctors will determine appropriate hormone doses according to individual conditions and needs. By adjusting the use method and dosage of hormone, the incidence of multiple births can be reduced, thus avoiding some risks associated with multiple births.
Clinical data and risk factors
According to the statistics of some research institutions, the incidence of multiple births in IVF infants using hormone therapy is relatively high. A study shows that the incidence of twins can reach about 30% in IVF infants who use hormone therapy.
In addition to hormone use, the characteristics of IVF patients will also affect the occurrence of multiple births. Age, ovarian reserve and ovarian responsiveness are related to the occurrence of multiple births.
Therefore, in the process of IVF, doctors will develop the most appropriate hormone program according to the specific conditions of patients to reduce the risk of multiple births.
summary
Whether IVF hormone use will lead to multiple births depends on many factors. Physiologically, hormone therapy can increase the number of ovarian ovulation follicles, thereby increasing the risk of multiple births; However, this risk can be reduced by reasonable use of hormone therapy, control of dosage, and hormone program according to the individual condition of the patient. Clinical data show that the incidence of twins is higher in IVF infants who use hormone therapy, but not all patients will have multiple births. Therefore, in the process of IVF, doctors will comprehensively consider the physiological conditions of patients and develop personalized treatment plans to reduce the risk of multiple births.
