The forming factors of dragon and phoenix fetuses in test tube babies
In vitro twins refer to the successful implantation and development of embryos carrying both female and male chromosomes during in vitro fertilization through assisted reproductive technology. However, the formation of test tube twins is not a simple probability problem, and there are many factors that will affect it. The following four aspects will be elaborated in detail: embryo transformation, embryo implantation, hormone influence and individual characteristics.
Embryonic transformation
IVF embryo transformation refers to the process in which an embryo develops from a single cell stage to a multicellular stage in the process of in vitro culture. This transformation process is one of the important factors that affect the formation of twins. Studies have shown that embryos with strong transformation ability are more likely to form twins. The ability of embryo transformation mainly depends on its own genetic characteristics and chromosome quality. In addition, the quality of culture environment and embryo culture operation technology will also have an impact on embryo transformation.
On the one hand, high-quality culture environment can provide the nutrients and oxygen needed by embryos, and promote the normal development of embryos. Hospitals with better development of modern medical science and technology, such as Peking Union Medical College Hospital, Shanghai Jiaotong University Medical College Affiliated Obstetrics and Gynecology Hospital, have advanced cultivation equipment and quality control system, providing a more suitable culture environment for embryo transformation.
On the other hand, the success of embryo transformation is also related to the proficiency of operation technology. Professional medical staff can operate accurately in all aspects of embryo culture, which can reduce the impact of human factors on embryo health and improve the probability of the formation of twins.
Embryo implantation
The formation of twins in vitro is also affected by the factors of embryo implantation. Embryo implantation refers to the process of implanting the in vitro cultured embryos into the mother's uterus through minimally invasive technology after the culture time to achieve pregnancy. The technical level of implantation and hormone status will affect the formation of twins. For example, the selection of implantation sites, the number of embryos implanted, and the timing of implantation will affect the formation of twins.
In addition, hormone level is also one of the important factors that affect the twins in vitro. For example, progesterone and other hormones will affect the growth and development of endometrium, thus affecting the implantation quality of embryos. Regular monitoring and adjustment of hormone levels in patients is essential to ensure the suitability of the intrauterine environment and the success of embryo implantation.
Hormone effects
Hormone level and balance will also affect the formation of test tube baby twins. Hormones play a role in regulating physiological functions in the body, and their influence on embryonic development cannot be ignored. The supply and adjustment of endogenous and exogenous hormones will affect the quality of eggs and sperm and the formation of embryos.
For example, in the regulation of ovulation induction cycle, the use and dosage control of hormones such as ovulation stimulating hormone can affect the quality and quantity of egg development. Appropriate hormone dosage and monitoring can improve the quality of fertilized eggs and increase the chances of the formation of twins.
Individual characteristics
The formation of test tube baby twins is also related to the individual characteristics of the patient. Age, birth history, genetic background and other factors will affect the success of pregnancy and the formation of twins.
The study found that female age is an important factor affecting the formation of dragon and phoenix fetuses in IVF. Older women have a relatively low chance of the formation of twins due to the decline of egg quality and ovulation function. In addition, women who have had childbearing experience have a higher chance of forming twins than women who have not had children. Genetic background is also one of the factors that affect the formation of dragon and phoenix fetus. Some genes may be related to the formation of dragon and phoenix fetus, but the specific mechanism remains to be further studied.
Summary
The formation of dragon and phoenix fetuses in IVF is affected by multiple factors. Embryo transformation, embryo implantation, hormone effects and individual characteristics are the most obvious aspects. The genetic characteristics and background of the embryo itself, as well as the culture environment and operation technology will have an impact on the formation of dragon and phoenix embryos. Rational use of hormone regulation and close monitoring of individual characteristics will help to improve the probability of the formation of dragon and phoenix fetuses in IVF.
