Eggs, Embryos and Sperm Freezing

Do you know that frozen sperm, eggs or embryos remain healthy and can be successfully used in fertility treatment years later?

Cryopreservation or freezing of eggs, sperm or embryos is done for various reasons. Here’s a quick look at what happens when you freeze your eggs, sperm or embryos.

Embryo freezing

During your IVF cycle, more than one egg is fertilized with sperm. This may result in more than one good embryo which can be frozen and stored so you can use them in future, without starting a new IVF (In Vitro Fertilization) or ICSI (Intracytoplasmic Sperm Injection) cycle.

Embryos that are safely preserved at extremely low temperatures in liquid nitrogen can be stored for many years and still remain healthy and viable for use.

If you need to use them in a future IVF cycle, you’ll have frozen embryo transfer. Then the embryo is thawed and transferred to the uterus for the highest chance of pregnancy.

Egg freezing

Women fertility decreases with age. This is why many women choose to freeze their eggs so that they can start a family later in life. Egg freezing is also an option for women who have to undergo some medical treatment which can affect their fertility. Transgender patients about to undergo a sex-change may also choose to freeze their eggs.

Egg freezing involves stimulating ovaries to produce mature eggs. The eggs are then collected and frozen in an advanced lab using vitrification. Vitrification is a special fast-freezing method which ensures high survival rates for frozen eggs.

Several factors that can influence success when the egg is thawed because you wish to have a baby. These include – your age at the time of freezing and collecting the eggs. Egg quality decreases with age, so it is best to store them earlier than later.

Sperm freezing

Sperm freezing allows men to preserve their fertility. Many men opt to freeze their sperm –

  • before an upcoming medical treatment that may affect sperm quality and production
  • before vasectomy in case they want to have future children
  • if they are in the armed forces and at risk of injury.

For sperm freezing, you’ll undergo a health screening and provide samples of your sperm, which will be preserved in liquid nitrogen.

When you’re wanted to start a family, your sperm will be thawed and assessed for use in fertility treatment such as IVF or ICSI.
