Cryopreservation of Embryos

After embryo transfer is done and there are surplus embryos of good quality, these can be cryopreserved and thawed in the future for another embryo transfer, providing more opportunities for pregnancy. Some patients may have overstimulated ovaries with associated discomforts which may be heightened after implantation or may have to delay embryo transfer for some reasons, can have their good quality embryos cryopreserved for future thawing and embryo transfer. At present, according to the provisions of the artificial reproduction law, embryos can be cryopreserved for 10 years.

Sperm cryopreservation:

If there are conflicts in schedule that the husband cannot collaborate with the wife’s treatment schedule, sperm can be cryopreserved ahead of time. Fresh sperm is best for couples if semen analysis reveals the sperm conditions is not good enough.
