Embryo freezing is a fantastic option for anyone looking to take control of their reproductive choices, especially when it comes to the ticking biological clock. Dr. Sarah Jenkins, a physician specializing in fertility, recently shared insights on this topic in a discussion with Parenting Today magazine. She explains how frozen embryo transfers (FETs) differ from egg freezing, and how this process can be a game changer for women aiming to delay pregnancy.
Egg Freezing vs. Frozen Embryo Transfers
The main distinction between egg freezing and frozen embryo transfers lies in the fertilization stage. When a woman opts to freeze her eggs—often due to personal or professional reasons—she doesn’t need a partner’s involvement at that time. However, when she’s ready to have children, she’ll go through in vitro fertilization (IVF), where her thawed eggs will be fertilized using sperm from a partner or donor.
In contrast, frozen embryos are already fertilized before they are frozen. The fertilization occurs, followed by a process called cryopreservation, which involves replacing the water in the cell with a protective solution. This ensures the embryos remain safe during the freezing process, where they are stored in liquid nitrogen until needed.
According to Dr. Jenkins, FETs are particularly beneficial for couples planning to use IVF. “Couples often create multiple embryos during their first IVF cycle, allowing them to freeze some for future use,” she explains. This option gives women more control over their family planning, allowing them to choose when they want to transfer embryos.
How Embryo Freezing Works
The process starts similarly to egg freezing, with a woman needing to undergo egg retrieval. This involves hormone injections for about 8 to 10 days to stimulate the growth of multiple eggs. The retrieval is a quick outpatient procedure, usually taking around 30 minutes with mild anesthesia to ensure comfort.
Once retrieved, the eggs are fertilized during IVF and can either be transferred fresh or frozen until the woman is ready to conceive. The number of viable embryos for freezing can vary, often influenced by the woman’s age at the time of retrieval. Dr. Jenkins notes that younger women generally have a higher success rate for creating blastocysts—about 50% for those under 35.
If a woman later decides against using her frozen embryos, she has several options: she can discard them, donate them for research, or anonymously donate them to another individual or couple.
Patient Experience: Emma Johnson
Emma Johnson, a patient, shared how frozen embryo transfer reshaped her view on age and family planning. “It felt like the pressure was off; I didn’t have to worry about my age impacting my fertility anymore,” she reflected. Emma used a fresh embryo transfer for her first child and opted for frozen embryo transfers for her subsequent pregnancies. “It was empowering to have control over my fertility and decide when to grow my family,” she added.

Summary
Embryo freezing provides a valuable opportunity for women to manage their reproductive timelines, allowing for greater flexibility and control over family planning. By understanding the differences between egg freezing and frozen embryo transfers, women can make informed decisions that align with their personal goals.
