Egg Freezing, which is also known as mature oocyte cryopreservation, refers to the method through which reproductive potential is restored among women. Eggs get harvested from the ovaries, frozen and in an unfertilized manner and are stored for purpose of using them later on. The egg freezing procedure is recommended for those women, who would like to delay conceiving baby due to various kinds of reasons.

Before the freezing of eggs, it is important to first retrieve the eggs. Let us look at how the eggs are retrieved, followed by the procedure of egg freezing through two different ways.

Retrieval of Egg

Egg Retrieval takes place just like it is done in case of in vitro fertilization (IVF). Women would need to be put under medication for hormones or through injections, which shall lead to the stimulation of ovaries, leading to more eggs getting matured. After this women would receive the necessary medication to stimulate ovulation and then the extraction of eggs takes place through the use of a needle. Specialists perform this whole procedure by putting women under the effect of anesthesia and are also guided by ultrasounds. Once the extraction is completed, the freezing takes place.

There are two different techniques involved in the egg freezing process. They include:

Slow Egg Freezing Method

A substance called cryoprotectant is used in order to protect the biological tissues from getting damaged out of freezing. This slow freezing method of getting eggs freezed relies on low initial concentrations of crytoprotectant. The cryoprotectant in low concentration is introduced when the egg is at a relatively warm temperature and still continues to experience the usual functions of a living cell. Then the cryptoprotectant would spread all throughtout thus fill the egg, hence replacing most of the water inside the egg. The egg is then inserted into a small container made of plastic and ultimately get placed inside a cooling chamber. The lowering of temperature, to around -6 degree centigrade, takes place through injecting very tiny amounts of liquid nitrogen into the cooling chamber. The cooling process is controlled by a computer.

The main purpose of these techniques is to avoid ice crystals from getting formed in the egg. During the spreading of the cryoprotectant, if the ice crystals are still present, they can cause damage to the egg and hence the egg may not survive the process of thawing. Then the temperature is lowered further to around -32 degree centigrade. By this time, the egg s metabolic rate become slow. The container where the egg was placed, is then dipped inside the liquid nitrogen, forming a solid.

Rapid Egg Freezing Method or Vitrification

At the time of rapid freezing method, there is high concentration of initial cryoprotectant whereas the cell remains at room temperature. The egg is unable to stay for long in this temperature and thus gets poured immediately onto the liquid nitrogen. Cryoprotectant spreads at a rapid rate so as to avoid ice-crystal from getting damaged. Vitrification is a very new method for freeing eggs. Recent research has shown that vitrification of eggs largely improves the possibility for survival after thawing and the rates of pregnancy.

Different Techniques That Can Be Used For Egg Freezing!

In vitro fertilization (IVF) is a process of fertilization in which eggs (ova) from a woman's ovary are removed. They are combined with sperm outside the body in a laboratory procedure, and then the fertilized egg (zygote) is transferred to the same or another woman s uterus for a successful pregnancy.

IVF is one of the several assisted reproductive techniques (ART) used to help infertile couples to conceive a child.

Causes of Infertility

Blocked fallopian tubes
Hormonal imbalance
Endometriosis
Women with ovulation disorder
Uterine fibroids
In the man, low sperm count or poor quality sperm
Genetic disorder
Procedures
Two procedures are done to gain access to ovaries

It involves inserting the needle through the vagina (transvaginally). With the help of an ultrasound machine, the physician guides the needle to the location of the ovaries
In the other procedure, called laparoscopy, a small thin tube with a viewing lens is inserted through an incision in the navel. This lets physician to see inside the patient, and locate the ovaries.
Method
Without additional techniques, the chances of pregnancy would be extremely small. The additional techniques used in IVF include-

Ovarian hyperstimulation- Stimulation to induce development of multiple follicles of the ovaries.
Final maturation induction- Induction of final oocyte maturation is performed, generally by an injection of human chorionic gonadotropin (HCG), when the ovarian follicles have reached a certain degree of development. This is known as the "trigger shot  
Egg and sperm preparation- Semen is prepared for fertilization by removing inactive cells and seminal fluid in a process called sperm washing. An oocyte selection may be performed prior to fertilization to select eggs with optimal chances of successful pregnancy. 
Co-incubation- Eggs are removed from the woman and placed in one of the fallopian tubes, along with the man's sperm. This allows fertilization to take place inside the woman's body. Therefore, this variation is actually an in vivo fertilization, not in vitro.
Embryo culture- The main durations of embryo culture are until cleavage stage (day two to four after co-incubation) or the blastocyst stage (day five or six after co-incubation)
Embryo transfer- The number to be transferred depends on the number available, the age of the woman and other health and diagnostic factors. Embryos are transferred to the patient's uterus through a thin, plastic catheter, which goes through her vagina and cervix.
Aftercare
After the IVF procedure is performed the woman can resume normal activities. A pregnancy test can be done approximately 12-14 days later to determine if the procedure was successful.

Risks

Multiple pregnancies
Ectopic pregnancy
Ovarian rupture, bleeding
Infections
Complications of anesthesia

Daljindar Kaur's inspiring story of motherhood: How IVF became her savior

The success of In vitro fertilization continues in India as a septuagenarian woman gives birth to a baby boy. Even after 46 years of marriage, the couple from Amritsar was childless. Daljinder Kaur, along with her 79-year-old husband, Mohinder Singh Gill, had been visiting National fertility and the Test Tube Baby Centre in Hisar since 2013 and did not give up even after two failed IVF cycles. They had faced ridicule for their inability to have a baby and yet they kept their hopes up.
On the 19th of April, the couple was blessed with a baby boy who is nothing less than a miracle. The groundbreaking achievement of the embryologists from Hisar has been an inspiration and a beacon of hope for couples all across the country. Once again, IVF has proved to be one of the most successful procedures to have babies for couples with fertility issues. Following are some of the advantages of In vitro fertilization, which you should know about-
1. It can be used by anybody
In-vitro fertilization is not necessarily used by the going to be a mother. It can be used by gestational carriers or by a surrogate as well. So it depends on whether the parents want to take the help of a surrogate or themselves want to be involved in the pregnancy. IVF gives an opportunity to single women and same-sex couples to become parents.
2. Use of donated eggs and sperms
There might be circumstances when the doctor can recommend using donated sperms or eggs. In that case, the eggs can be fertilized manually in the lab and the fetus developed can be used for in vitro fertilization. This increases the chance of pregnancy by a fair amount.
3. Control over timing
In vitro fertilization is a solution for couples who have a very engaging professional life, and can be an option for people who want to have babies after a certain point of time. Eggs and embryos can be preserved for future use. It is also helpful for couples who already have a child and plan to have another later.
4. Decreases chances of miscarriage
Genetic abnormality is one of the primary causes of miscarriage. The technique of preimplantation genetic diagnosis (PGD) is used to ensure the viability of the embryo much ahead of time so that the mother can have an uncomplicated pregnancy and carry her baby full term.



Daljindar Kaur's inspiring story of motherhood: How IVF became her savior

Women undergo menopause in their 40s and this is primarily known as the age after which they can't bear children in their wombs any more. The ability to develop and maintain a healthy pregnancy wanes as a woman crosses the age of 30, which according to research is the optimal time for a woman to become a mother.

The body undergoes changes as it gets older and women slowly start losing the perfect conditions for pregnancy. However, with the rise of the IVF treatment for infertility, a great number of people are choosing to embrace parenthood at a relatively advanced age. However, the question is, can the same IVF treatment prove effective for a woman after her menopause?

The answer is yes. There have been several instances where a woman past menopause has been implanted with a fertilized egg and has been able to conceive a healthy offspring from the same. However, such an IVF treatment is much more complex and can require a lot of external hormonal treatments on the side as well.

How can IVF help menopausal women?
Women, who have gone into menopause more than 6 months ago, require additional care to achieve pregnancy through IVF. The uterus is usually shrunken in such people and the endometrial lining also develops a resistance to estrogen. Several cycles of estrogen treatment are needed for such women to achieve a healthy pregnancy.

Most doctors suggest at least a couple of months of estrogen and progesterone treatment prior to taking the actual IVF treatment. However, there is no guarantee that the same will be effective in every case.

By any chance, if the menopausal woman chose to store her eggs prior to her menopause, she can get those eggs fertilized and implanted after menopause, using the IVF method, in order to achieve a healthy pregnancy. Through, this procedure, the woman can not only become pregnant after menopause but can also ensure that she is the biological mother of the child who would be born.

At any rate, it is best to undergo the IVF treatment before menopause, as this improves the chances of conceiving. The hormonal treatments are often easier and most women can completely forego the progesterone and estrogen supplementation in such a case. This will not only reduce the time required to complete the treatment but will also significantly reduce the cost that the parents have to bear.

Can IVF Help Menopausal Women Get Pregnant?

In vitro fertilisation, commonly known as IVF, is the process of fertilising single or multiple eggs outside the body. This treatment can be performed by either using your own egg and sperm or using donated egg or sperm or sometimes both. The resulting sperms and eggs are evaluated for quality and then one or more of them are positioned properly in the uterus through the cervix. IVF is regarded as one of the most commonly opted treatment plans, and it accounts for more than 99% of assisted reproductive technology processes.

Who are suitable for IVF?
IVF can be helpful for you in case you have some issues with the egg quality or ovulation, fallopian tubes that are blocked in some way or endometriosis. It can also help you to get pregnant if your partner has problems with mortality and sperm count and when you have opted for donor eggs. About 1.5% of babies in the United States are conceived through the IVF process.

How does IVF work?
There are several steps through which IVF process works and the timeline follows the following steps:

    Stimulation for ovary: You will have to take a special kind of fertility drug for 8 to 14 days near the start of your menstruation cycle. This drug aids in the stimulation of your ovaries for developing multiple mature eggs to fertilise instead of a single one. You may also need to take an artificial hormone-like cetrofelix and leuprolide for keeping your body from releasing eggs very early.
    Development of follicle: When you are under all these medications, you will have to visit your doctor s office often for checking the hormone levels as well as ultrasound measurements for the ovaries.
    Getting the trigger shot: Once the follicles are ready, you are likely to receive a trigger shot, which is an injection causing the eggs for maturing fully and becoming capable of being fertilised. Your eggs are ready for being retrieved after about 36 hours of receiving this shot.
    Gathering the eggs: At this stage, you are likely to receive an aesthetic or ultrasound probe that is inserted through the vagina for checking the ovaries and identifying the follicles. Normally, about 8 to 15 eggs are retrieved through the insertion of a thin needle.
    Fertlisation: This is the most vital step, where an embryologist is going to examine the eggs before they are combined with the sperm and incubated overnight. Fertilisation happens at this particular time, but abnormal eggs are not fertilised.

Then the embryos slowly develop and are planted on the basis of your age and clinical condition. When the treatment is working, an embryo is implanted in the uterine walls and starts developing. 

IVF - How Does it Work?

IVF is a useful process for people who want to become parents but have exhausted all other means of being so. However, the in-vitro fertilization method is definitely not suitable for everyone. Here are some facts you need to know about the procedure and they will help you determine whether you are suited for the program or not.

1. IVF Takes Time
Even though most clinics may not tell you this, but the IVF procedure takes a bit of time to deliver the desired results. On an average, the treatment can take anywhere between four weeks to a couple of months to produce results, depending on the patient s ability to respond to the medicines used. The procedure involves artificially stopping the menstrual cycle of the woman. Next, the ovulation process is stimulated so that the healthy egg can be extracted from the womb. The eggs chosen are then fertilized and left to undergo embryo culture for another six days. After this, the eggs are implanted back into the mother s body.

2. The process Can Be Stressful
IVF treatment and pregnancy can be quite a stressful period of time for the parents in question. The mother needs to be constantly monitored to check for any abnormal response to the pregnancy. Regular checkups by the doctor along with blood tests may also be suggested. However, this stress has very little chance of affecting the quality of the pregnancy. So, do not worry that overstressing yourself will lead to complications for the embryo.

3. More Than One Cycle Needed For Pregnancy
IVF treatment occurs in cycles. Each cycle involves transplanting a fertilized egg into the womb. However, pregnancy, right after completion of the first cycle, is quite rare. In fact, almost all patients need to undergo several similar cycles in order to get pregnant. So, do not be disheartened if you do not get pregnant after undergoing the very first cycle of IVF treatment.

4. IVF Is Costly
Not everyone is able to afford the high cost of IVF. Others may be able to afford the cost of undergoing a couple of cycles of the same, after which the high costs can become a burden. Only a select few can bear to carry on with the treatment until the pregnancy arises. So, consider your financial condition prior to signing on for such a treatment option.

At any rate, consult with an expert to get an even better idea about the IVF procedure and the consequent pregnancy.
