What if you want children in the future but aren’t ready to start your family just yet? 

Sperm, eggs, and embryos can be preserved for future use through fertility preservation. People who wish to delay having children, or those preparing for medical procedures that might affect their reproductive health, may find this technique useful. 

The most common fertility preservation options are freezing eggs, sperm, and embryos. Each option uses a different technique and procedure, though all of them require keeping the reproductive cells or embryos at very low temperatures. 

The Whole Procedure of Egg Freezing

Egg freezing, also sometimes referred to as egg cryopreservation, is a method of collecting and preserving unfertilised eggs for potential future use. Women who intend to delay pregnancy, or who are preparing for treatments that may affect normal ovarian function, may choose this option.

Below are the steps involved in this procedure:

• Ovarian Stimulation: The ovaries are stimulated with hormonal injections 10 to 12 days before the treatment so that they develop multiple eggs instead of just one.
• Monitoring and Screening: Specialists can confirm egg formation with the help of blood tests and ultrasound scans. 
• Egg Retrieval: Once mature, the eggs are retrieved from the ovaries.
• Egg Freezing: Specialists examine the eggs and choose the suitable mature ones for further processing. Before freezing begins, a technique called vitrification is used to solidify the intracellular fluids of the eggs without forming ice crystals.
• Storage: The eggs are then stored in special tanks at extremely low temperatures until they are needed. 

Whenever a woman wants to use her frozen eggs, they are thawed using laboratory protocols. Once the eggs are in a suitable state, they are fertilised with sperm by ICSI. The resulting embryos are monitored carefully before a suitable one is selected for the transfer process. 

Not every egg that is retrieved will be suitable for freezing, and not every egg will become an embryo or be fertilised. The future probability of pregnancy depends on the total number of mature eggs stored and the age at which they were frozen. 

The Process of Sperm Freezing

Men can now preserve sperm for future reproductive procedures. This process is commonly referred to as sperm cryopreservation. It can be very beneficial for men who are planning to undergo chemotherapy, radiotherapy, or other surgical or non-surgical procedures that could affect sperm production. 

The process is as follows:

• Sperm Collection: The sperm sample is collected in a suitable container. 
• Semen Analysis: The lab processes the semen to assess sperm count, quality, quantity, and motility.
• Preparation of the Sample: A cryoprotectant, a liquid that aids sperm freezing, is added to the sample.
• Freezing and Storage: The sample is divided into small containers and stored at extremely low temperatures until future use.

Depending on sperm quality, the sample can later be used for procedures such as IVF, IUI, or ICSI. 

Embryo Freezing: How Is It Done?

Embryo freezing, unlike egg freezing, involves fertilised eggs before storage. Couples who want to save their embryos for a future pregnancy may opt for this procedure. It is normally carried out during an IVF cycle. 

The process of embryo freezing may involve:

• Stimulation of the ovaries
• Egg retrieval
• Development of the embryos: The chosen eggs are monitored until they reach the blastocyst stage (this takes 5 to 6 days).
• Embryo Testing (optional): Some couples may decide to undergo preimplantation genetic testing for specific chromosomal conditions. 
• Freezing and Storage

Whenever the couple is ready, the frozen embryos are thawed and used for pregnancy. Through embryo freezing, couples can use the frozen embryos without another egg removal. However, not every embryo results in a pregnancy, and not every egg is suitable to become an embryo. 

Which One of These Options Is Right for You?

The most suitable fertility preservation method depends on your age, medical history, reproductive goals, and whether you want to use donor sperm or eggs. It’s important to consult a fertility specialist about expenses, storage conditions, future treatment requirements, and the actual probability of pregnancy before going ahead with fertility preservation. Although it can open doors to new possibilities, fertility preservation cannot guarantee a pregnancy. 

Procedures including IVF, ICSI, IUI, embryo freezing, and sperm freezing are among the fertility treatment options available at NJINSKY IVF & Fertility Clinic. An in-depth consultation can help you decide which fertility preservation option best matches your condition. 

To Conclude

Whether you wish to delay having children or preserve your fertility for future use with the help of advanced treatment techniques, each approach offers a unique way to balance your fertility health. Your particular situation and future goals will determine which solution suits you best.
