Patient's question:
A while ago, I went to the hospital for in vitro fertilization and found that it was a frozen embryo level 8C3. I want to know if 8B is a grade 1 embryo?Doctor's answer:
The success rate of first-grade embryo transfer is generally around 50%. First-grade embryos are the best embryos, and blastocysts are selected at three days of development to be transferred into the uterine cavity. For in vitro fertilization, high-quality eggs are usually selected during the ovulation period and then cultured with sperm at a certain temperature to form a zygote. Embryos are generally divided into four grades: first and second-grade embryos are of high quality, third-grade embryos can also be transferred, while fourth-grade embryos are usually discarded due to their lower success rate of transfer. The success rate of embryo transfer is mainly affected by factors such as the quality of the zygote, the chromosomes of both partners, and the uterine environment. Maintaining a healthy lifestyle can greatly help in the recovery of the condition.
