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

In Vitro Fertilization - Quick Facts!

Recurrent pregnancy loss can be defined as the consecutive loss of three of more pregnancy. Recurrent Pregnancy loss is a medical condition in which the pregnancy loss occurs before completing 20 weeks in an involuntary manner. Pregnancy loss can be visualized using ultrasound technique.

What are the causes of recurrent pregnancy loss?
Most of the pregnancy losses occur due to various abnormalities in the genetic makeup of an organism or any chromosomal abberities. The abnormality can be present during the formation of an egg or sperm or the embryo. However it is well said that the miscarriage usually happens within first 12 weeks of conception. Almost half of the times, women even don t realize that she is pregnant during first three months. The risk of recurrent pregnancy loss increases with the increase in previous miscarriages.

Recurrent pregnancy loss is more common in the women who conceive late according to their age. It is because the quality of egg formation decreases and this may lead to abnormalities in chromosome formation or division. Sometimes, it may happen that father and mother, both suffer from slight abnormality in their genes and hence, the fetus can be more severely affected and hence causes recurrent pregnancy loss in the uterus.

The weakening of immune system can also lead to recurrent miscarriages. Abnormality in the functioning or secretion of hormones can cause severe diseases such as diabetes and thyroid which can cause an impact. Also, blood clotting issues may also play an important role.

The gynecologists may help in the treatment of this medical condition but their treatment option depends upon the underlying cause of recurrent pregnancy loss.

The gynecologist recommends genetic counseling to those patients who have any chromosomal abnormality in their genetic makeup. Some of the couples can opt for prenatal genetic studies while expecting a child so as to keep a check on whether the child has normal genetic makeup. Some of the techniques used by the medical health providers are chorionic villi sampling, or amniocentesis. 

For genetic diagnosis, in vitro fertilization can also be done along with pre implantation. If there is any abnormality in the uterus or the tract in the female then surgery can be done so as to cure the defect. If there is a syndrome such as anti-phospholipids syndrome, then medications are provided in order to decrease the formation of blood clot.

Therefore, gynecologists are assisting in the treatment of recurrent pregnancy loss in females.

Why Your Baby's Health is Decided Much Before You Even Conceive

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?

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!

There are two methods by which abortion can be done:

Medical Abortion - Non-surgical abortion in which medicines are used to induce abortion

Surgical Abortion - Use of transcervical procedures for terminating a pregnancy, including vacuum aspiration, and dilatation and evacuation (D and E).

Surgical or Medical Abortion for Unwanted Pregnancy

If pregnancy is lesser than = 7 weeks; medical method with Mifepristone with Misoprostol is favorable as the success rate is as high as 97%.

If pregnancy is between 7-12 weeks; surgical abortion is the only option.

If pregnancy is beyond 12 weeks - 20 weeks, then the woman needs to be hospitalized and will be given either Mifepristone followed by Misoprostol tablet or only Misoprostol tablets and woman will then abort like a miscarriage in the hospital. If any products are remaining, then it will be evacuated surgically.

Surgical abortion is preferred if patient desires concurrent tubal ligation or IUCD (CuT) insertion.

If a woman fulfills the criteria for selecting either method i.e. before 7 weeks, final choice has to be given to the woman.

Summary of choice between Surgical or Medical abortion in India

lesser than = 7 weeks - Medical method or surgical method

7-12 weeks - Surgical abortion

12 - 20 weeks - Medicines with or without surgical procedure in hospital

Advantages of Medical Abortion

Avoid surgery

Controlled by the woman and may take place at home

No need for admission to the hospital

Usually, well tolerated by women, if properly counselled and motivated

No need to take leave from work, as bleeding can be managed with menstrual pads even while in the office or at work.

Disadvantages of medical abortion

Takes time (hours to days) to complete abortion, and the timing may not be predictable. Women experience bleeding and cramping, and potentially some other side-effects (nausea, vomiting, fever, and shivering). May require more clinic visits than surgical abortion.

Advantages of Surgical Abortion

Quick procedure

Complete abortion easily verified by evaluation of aspirated products of conception

Takes place in a hospital so Sterilization or placement of an intrauterine device (IUD) may be performed at the same time as the procedure. It can be performed under local anaesthesia if woman is properly motivated and counselled

Disadvantages of surgical abortion

Requires instrumentation of the uterus

Small risk of uterine or cervical injury

Timing of abortion controlled by the doctor and hospital

Anaesthesia needs to be administered. Most doctors perform this procedure under short general anaesthesia. A woman needs to be in the hospital for at least 6 hours. Effect of sedation will be there throughout the day.
