Failure of Egg Retrieval Sample Clauses

Failure of Egg Retrieval. It is possible that the aspiration will fail to obtain any eggs or the eggs may be abnormal or of poor quality and fail to produce any viable eggs. Cryopreservation Because ice crystals can form within the eggs and damage them, the embryologist places the eggs in special solutions to remove the water from the eggs and then bathes them in protectant solutions during the ‘flash’ freezing process known as vitrification. Eggs may not survive the freezing process or technical or mechanical or power failures may occur causing loss of some or all of the eggs. This may or may not affect the cryopreserved egg’s capacity for fertilization or implantation. Storage Cryopreserved / vitrified eggs are stored in liquid nitrogen storage containers until they are removed for warming. Technical, mechanical or power failures can occur at any point in the freezing process or anytime during the storage which could result in the loss of the future viability of the eggs. Likewise, once the eggs are in storage, technical problems, terrorism, fire, and certain acts of nature (earthquake, prolonged loss of power, etc) could result in the loss of some or all of the frozen eggs. Summary of future procedures for subsequent attempts at egg fertilization, embryo growth in vitro, and embryo transfer using the cryopreserved eggs from this cycle (those later procedures requiring subsequent separate informed consent and agreement documents) : At a time when you wish to attempt to conceive, you will be given medication to regulate your cycle to coincide with the time of egg warming. For the eggs that survive the warming process (if any), trained laboratory personnel will perform Intra-Cytoplasmic Sperm Injection (ICSI), a procedure where one sperm is directly injected into each mature egg using a very fine glass needle to achieve fertilization. The risks of ICSI include damage to either the egg or sperm resulting in either lack of fertilization or death of the egg or sperm. In some instances, the damage is more subtle and the embryo produced will not be normal and will have to be discarded. Successful fertilization rates with ICSI are similar or superior to routine in-vitro fertilization in the hands of experienced qualified embryologists. As with all laboratory procedures, there is a risk of damage to the egg and/or sperm during handling. There is no guarantee of how many or that any of the frozen eggs will survive the warming process or how many or if any of them will successfully fertiliz...
