Women who wish to delay having children have the option to freeze their viable eggs to start a family later on. This procedure is known as "egg freezing" and is done by cryopreserving a female's eggs for later use.
Egg freezing first begins with a cycle of hormone injections, to stimulate the ovaries. Your doctor will teach you how you give yourself the injections, so that they can be regularly carried out by you at home. After around 2 weeks, the eggs are matured and the extraction starts.
Here is how an egg freezing procedure goes:
When the woman is ready to use the eggs, they will be thawed to room temperature in a matter of seconds. The eggs will then be fertilized using Intracytoplasmic Sperm Injection (will link). After fertilization, the eggs will be transferred into your uterus (after making sure the endometrium lining is ready).
Just like egg freezing, sperms can also be frozen for later use. Many men undergoing cancer treatment, or even before a vasectomy, can choose to freeze their sperms. The process is similar to egg freezing, whereby sperms are collected by the man himself, at home or the clinic. Following this, they will be rapidly cooled to freezing temperatures and preserved for a number of years. These sperms can later be thawed and then used during IVF, IUI or ICSI treatments.
