Does It Easy for In Vitro Fertilization to Successfully Produce a Boy-Girl Twin?

In vitro fertilization-embryo transfer (IVF-ET) refers to the technique of fertilization and embryo transfer outside the body. If high-quality blastocysts are selected, the survival rate is relatively high, around 10%. If the blastocysts develop poorly, the survival rate is lower, and it is necessary to seek timely treatment in a formal hospital. IVF-ET is mainly used to address cases where natural pregnancy or artificial insemination fail.

Generally, two blastocysts are implanted at a time. If both blastocysts are of high quality, the probability of becoming twins is relatively high, typically around 50%. However, the probability of having twins of different sexes (dragon and phoenix twins) is lower, mostly around 10%. If high-quality blastocysts cannot be implanted, the survival rate of the blastocysts may decrease, and the probability of twins becoming even smaller.

The survival rate of blastocysts is influenced by various factors such as sperm quality, egg quality, and uterine environment. After successful implantation, it is necessary to closely monitor any changes in the body to check for pregnancy. IVF-ET requires a relatively long period of time, involving ovarian stimulation, egg retrieval, fertilization, and embryo culture. During the treatment period, it is important to avoid psychological stress and follow the doctor's advice for the next steps of treatment.

If a successful pregnancy is achieved, it is crucial to monitor the growth and development of the fetus.
