Frozen Embryos are embryos created during an IVF cycle and preserved for future use. Embryo freezing is an important advancement in fertility treatment because it allows suitable embryos to be stored and transferred at a later time without repeating the entire egg-retrieval process. During IVF treatment, eggs are collected and fertilized with sperm in a laboratory. The developing embryos are carefully monitored by embryologists. When suitable embryos are available, they may be transferred to the uterus or preserved for future treatment. Modern vitrification techniques allow embryos to be frozen rapidly and stored under controlled laboratory conditions.
