An embryo frozen as an egg cell, inseminated egg cell or already frozen as an embryo is transferred into the uterine cavity either in the natural cycle or after hormonal stimulation.
During the process of cryo-preservation, the water is removed from the cellular tissues in a preparation stage. This enables the cryo-procedure to effectively freeze cellular material without the risk of damage. This is extremely important as any presence of water will result in the formation of ice crystals that would damage sex cells, embryos and other material that is designated for preservation.
There are several advantages to utilizing Cryo-Cycles in conjunction with a surrogacy program. An embryo frozen as an egg cell, inseminated egg cell or already frozen as an embryo can be transferred into the uterine cavity either in the natural cycle or after hormonal stimulation which significantly decreases the cost to achieve multiple pregnancies with surrogates through additional hormonal procedures.
Often, after the transfer of embryos into the uterine cavity during the process of in-vitro fertilization (IVF), some embryos remain. These embryos can be preserved for a long time with the help of cryo-preservation. This process enables embryos to be used in future IVF procedures to create sibling groups.
Typically, in cryo-cycles, eggs, inseminated eggs, or an embryo is frozen. Sometimes for this process to work optimally, the surrogate is required to take HRT hormones before the implantation of the already-frozen embryo. These hormones help the lining of the uterus to be prepared to carry a pregnancy to term. Nevertheless, for those interested in creating sibling groups or those who feel that they may desire full siblings for their child in the future, cryo-cycles offer plenty of options.
The use of Cryo-cycles is optimal in cases where donor oocytes, developed embryos, sperm and eggs are not readily available to arrive at our medical facilities on the day where treatments or procedures are to take place. This option is also advantageous in cases where various screenings are required to isolate and eliminate threats of hereditary diseases, and where ongoing IVF treatments are required. Additionally, cryo-cycles assist in scenarios where scheduled implantation may not be able to occur due to a surrogate’s endometrium not being ready for the transfer of an embryo or in cases of Hyperstimulation Syndrome where the transfer of an embryo would risk the health and development of a future child. One major advantage to the use of Cryo-Cycles is the peace of mind that this procedure offers prospective parents. It is scientifically proven that cryopreservation of an embryo has no adverse side effects on the health of your future child. Intended parents who choose Cryo-Cycle procedures can take comfort in the knowledge of this reliable and safe option.
