Vitrification is the procedure of freezing of ova, zygotes, embryos, and blastocysts. Unused and not transferred haploid cells are frozen until the patient expresses the will to unfreeze them.
When is the procedure applied?
If you have a condition, or are facing medical treatment for condition (like chemotherapy), that may affect your fertility, you are about to have a vasectomy and want sperm available in case you change your mind about having (more) children, you have a low sperm count or the quality of your sperm is deteriorating, you have difficulty producing a sperm sample on the day of fertility treatment, you are at risk of injury or death (for example, you're a member of the Armed Forces who is being deployed to a war zone), or you're transitioning from male to female or from female to male.
In the future, the unfrozen sperm can be used to fertilize his partner using IUI, IVF or ICSI assisted reproductive techniques.
The advantages of vitrification
Using vitrified ova, zygotes, embryos, or blastocysts can avoid the unnecessary use of fertility medications in the future.
