Four Future Pregnancy Options Using Egg Freezing

The process of removing, freezing and storing a woman's eggs after the ovaries are stimulated is known as Oocyte cryopreservation

. As the timings of conceiving of a baby comes near for a lady, eggs get fertilized, though the lady may not necessarily be the source.

Oocyte cryopreservation has been regarded as an alternative for women with different conditions and issues hoping to have children in the future. You will understand why this process is a better choice for many women once you know how it works. In order to use a lady's eggs for use in the times to come, herein given is a brief narration of the methodology of the working of the egg-freezing process:

Ovary stimulation

To begin the process of oocyte cryopreservation,or egg freezing, you will have to go through a process of follicle stimulation which is achieved by injecting yourself with a hormone daily for one to three weeks. The ovaries are stimulated by FSH. While hormones are being injected, your doctor shall regularly monitor your ovaries and conduct blood tests and ultrasounds to make sure your eggs are healthy until they are ready for harvesting.

Egg extraction

You will be given a medication that will set off ovulation when the eggs have matured and are ready for harvesting. The client is sedated while the egg is retrieved which takes about fifteen minutes. An ultrasound-guided needle will be inserted through your vagina to the ovarian follicles to remove the fluid. This fluid now contains the eggs, the number of which is determined by how well your body responded to the follicle stimulating hormone. The fluid is the examined under a microscope to determine the number and condition of eggs it contains.

Egg freezing

A cryoprotectant solution is using during the freezing process to dehydrate water-filled eggs. Soaking eggs in this solution prevents the formation of ice crystals that may cause the destruction of the egg's integrity. Two processes, a slow-cooling method or a vitrification process, are used for freezing.

The eggs can be gradually frozen by dropping the temperature a half-degree at a time in the slow-cooling method. Many fertility clinics utilize the sluggish freezing way.

The vitrification process, on the other hand, allows the eggs to freeze faster but requires more cryoprotectants during the freezing process.

At this time, no significant differences have been observed between the two methods of freezing eggs.

Fertilization

Once the eggs are frozen, they can be used by any woman for assisted reproduction. One way of assisted reproduction is by borrowing eggs from other women. Once the recipient is ready to conceive, the eggs are thawed by a specialist and introduced to the sperm. The eggs in excellent condition are subjected to a process named intracytoplasmic sperm injection. The sperm normally penetrates the egg, but in this process, the sperm is actively inserted. The fertilized eggs are then set in your uterus using a catheter, expecting at least one egg will result in a successful pregnancy.

For women who want to preserve their eggs for future pregnancies-whether they are going through assisted reproduction or have been diagnosed with cancer but have not yet begun chemotherapy or radiation treatments (which are known to destroy eggs), oocyte cryopreservation,(egg freezing), is particularly helpful.
