Blastocyst-assisted hatching is generally better able to help with better transfer and has a positive effect on improving the success rate of implantation. Assisted hatching is an important part of assisted reproductive technology. Blastocyst-assisted hatching refers to the use of artificial techniques to make holes in the zona pellucida or to make the zona pellucida thinner or even dissolve and disappear before the embryos are transferred back to the woman’s uterus in IVF procedures, which can help the embryos to hatch and thus encourage them to enter the uterus more easily. If a woman’s zona pellucida is too hard and too thick, it will cause the embryo to be unable to enter the uterus. The thickening and hardening of the zona pellucida is usually found in the bodies of women over 35 years of age, so it is more suitable for blastocyst assisted hatching for such women. If women want to have assisted reproduction technology, it is recommended to consult a doctor in time, under the doctor’s guidance, complete the relevant examinations to clarify whether it is suitable for assisted hatching of blastocysts, and then take corresponding measures.
