What are frozen eggs and how are they preserved?
Frozen eggs, also known as cryopreserved eggs, are eggs that have been frozen to preserve their viability for future use. The process of freezing eggs involves several steps, including ovulation induction, egg retrieval, and vitrification. During ovulation induction, medications are used to stimulate the ovaries to produce multiple eggs. Once the eggs are mature, they are retrieved through a minor surgical procedure and then frozen using a process called vitrification, which involves the use of cryoprotectants to prevent ice crystal formation and preserve the eggs’ structure.
The frozen eggs are then stored in liquid nitrogen at a temperature of -196°C, where they can remain viable for many years. The preservation of frozen eggs is critical for women who want to delay childbearing due to various reasons such as career, health issues, or lack of a partner. Frozen eggs can also be used for fertility treatments like in vitro fertilization (IVF), and they offer a viable option for women who are at risk of losing their fertility due to medical conditions or treatments. With the advancement in technology, the process of freezing eggs has become more efficient, and the success rates of using frozen eggs in fertility treatments have improved significantly.
