Such machines are used for freezing oocytes, skin, blood products, embryo, sperm, stem cells, and general tissue preservation in hospitals, veterinary practices, and research labs. The number of live births from 'slow frozen' embryos is some 300,000 to 400,000 or 20% of the estimated 3 million in vitro fertilized births. Dr Christopher Chen ...
Undermining use of frozen embryos in IVF would introduce many uncertainties, delays and possible additional expenses, according to fertility experts. Here is what you need to know about the ...
