After thet ovaries are stimultated, the eggs can be removed, preserved and stored in a process called 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.
An alternative for women who wish for children is Oocyte cryopreservation. Knowing how this process works will help you understand why it has become a better option for many women. 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
You will need to have injections of follicle stimulating hormone (FSH) once per day for 1-3 weeks; this starts the process of oocyte cryopreservation. In order to stimulate your ovaries to produce multiple eggs, one uses FSH Your doctor will regularly do blood tests and ultrasounds to make sure your eggs are healthy while hormones are being injected.
Egg extraction
When the eggs have matured and are ready for harvesting, you will be given a medication that will set off ovulation. For the execution of the egg retrieval method, you will have to undergo soft common anesthesia or sedation lasting for approximately fifteen minutes. A needle, guided by ultrasound, is inserted into your vagina to remove the fluid from ovarian follicles. This fluid now contains the eggs, and the number of eggs depends on how your body responds to the FSH. 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. As the formation of ice crystals can destroy the integrity of the egg, the eggs need to be soaked in this solution. The freezing process can be conducted by using either a slow-cooling method or a vitrification process.
In slow freezing method, the eggs are frozen gradually by decreasing the temperature by half a degree each time. The slow freezing method is used by most fertility clinics.
However, vitrification gives the eggs a chance to freeze at a speed which is faster but will need more cryoprotectants.
The two different methods have had no visible impact on frozen egg storage
Fertilization
These frozen eggs are not limited for use by the owner alone. They can also be donated to other women for assisted reproduction. The frozen eggs are removed from inside the freezer, then thawed by a specialist who makes sure that the thawing process is completed properly Once the eggs are prepared, the ones in the best condition are put through intracytoplasmic sperm injection to be fertilized. The sperm normally penetrates the egg, but in this process, the sperm is actively inserted. A catheter is used to place fertilized eggs inside the uterus. Hopefully one egg will cause a pregnancy.
Egg freezing, or Oocyte cryopreservation, is particularly helpful for women who want like to preserve their eggs for future pregnancy, for those going through assisted reproduction, and those diagnosed with cancer but who have not started chemotherapy or radiotherapy treatments which are known to destroy eggs.
