Why do some doctors recommend using blastocyst culture? Because blastocyst transplantation is more in line with human pregnancy mechanisms, with a high implantation rate and pregnancy probability, it can effectively reduce the risk of ectopic pregnancy. Moreover, high-quality embryo capsules are good because most women undergo in vitro fertilization and find that they are not high-quality embryos. In order to achieve success in implantation, doctors generally recommend that women choose to use embryo culture because not everyone's embryos are primary and secondary advantage embryos. Without knowing that high-quality embryos are the best, undoubtedly, embryo culture is the best method. It is necessary to incubate high-quality embryos in vitro, which can effectively improve the success rate.

1. Adapt to the human body because pregnancy involves the implantation of an embryo into the endometrium, which then begins to grow and develop. Women's endometrium may not accept embryos at all times, just like our land. Generally, crops cannot grow in winter, and there is a special time when the endometrium opens the door to welcome the embryo. This time point is usually on the 20th to 24th day of menstruation (6-10 days after ovulation), and the blastocyst is only on the 6th day, so the blastocyst and endometrium are more synchronized. The quality of successful embryos is very high.

2. The process of selecting embryo quality capsules is a survival process for the fittest. On the third day, embryos that look good but have poor internal quality are difficult to continue growing and developing during the cultivation process, and will naturally wither. This can reduce the number of transfer failures, reduce costs and energy waste, and successfully improve the quality of embryos with good developmental potential.

3. The probability of blastocyst pregnancy: Single blastocyst transplantation can reduce the incidence of twins and multiple births. Many people envy twins, and the risk of twins is generally not high. This time, it must be rational. Twins violate natural laws, and all things that violate natural laws will have consequences. Pregnancy of twins is not necessarily a good thing. Raising the sac can effectively reduce ectopic pregnancy.

4. On the third day of embryo transfer to reduce the risk of ectopic pregnancy, it may migrate for a period of time and enter the fallopian tubes, leading to ectopic pregnancy. After the blastocyst is transplanted into the uterus, it will quickly find a place to live, reducing the possibility of ectopic pregnancy. The disadvantage of high-quality embryo sac is that some rare women use high-quality embryo sacs, but if they fail, there may be the idea of why high-quality embryo sacs are not successful. In fact, the success rate of the sacs varies from person to person, and the sacs may eliminate some embryos or even all embryos with poor developmental potential. If the sacs fail, leading to no embryo transfer, if you cannot accept the risk of failure, carefully choose the sacs. Young people are the most suitable person.

Is it necessary to use high-quality embryo sac for in vitro fertilization? The editor of 592 Baobao Network believes that if allowed, it is possible to keep bags. Due to being young, having good ovarian reserve function, and having a large number of eggs, more than 8 mature eggs can be taken. On the third day, patients with high-quality embryos can freeze several high-quality embryos, the remaining embryo sacs, or all sacs. Excess embryos are screened through cysts to identify embryos with greater developmental potential, reducing freezing costs and failure rates. It can also improve the success rate.
