What extra measures one need to adopt at the time of embryo transfer?
Timing of Embryo Transfer The correct time for embryo transfer after thawing is a crucial factor. Attachment and implantation of the embryo normally occur early during the second week following fertilization. Therefore , careful monitoring of the ovulatory cycle near the expected time of ovulation is necessary to ensure that a thawed embryo can be replaced at a period of time in which that particular cell stage would normally be present within the reproductive tract. There is a window of time during which the embryo may be replaced, generally 24 to 32 hours. Embryonic age is calculated at the time from egg collection to the time of freezing. The endometrium is considered to be in synchrony with the embryo when the development of IV developed embryo matches that of normal embryo. Replacement of thawed embryo requires specific calculation of ovulation timing. This crucial factor determines the synchronization timing for frozen thawed embryo age and uterine age.
