If you are wondering what is IVF and Test tube baby, whether both the terms are related, let us try and understand them in detail. Test tube baby is a term that refers to a child that is conceived outside the women’s body by a scientific process known as In-Vitro fertilization or IVF treatment. This entire process is done in a laboratory. In this process the eggs are taken from the mother’s ovary and fertilised by the sperms from the father.
The fertilised egg is cultured for 2–6 days and allowed to divided 2-4 times inside a test tube (hence the name test tube baby) These eggs are then returned back to the mother’s uterus where it can be developed normally, this is done with the intention to establish a successful pregnancy.
This procedure has greatly helped women having infertility problems that are untreatable to give birth to healthy babies.
The test tube baby procedure was made possible by scientist Robert Edwards and gynecologist Patrick Steptoe in 1978 when the first test tube baby, Louise Brown was born in England. In 2010, Robert G. Edwards was conferred the Nobel Prize in Physiology or Medicine for developing the IVF treatment.
Now, IVF treatment has given many couples who are suffering from fertility problems a hope of becoming a parent. Since the first test tube baby in 1978 to recent times there have been millions of children who are born with the help of IVF treatment.
IVF procedure – An Overview
Now let us understand the steps involved in test tube baby process. The steps for test tube baby break in four phases. People planning for IVF treatment should know the steps for the process in depth.
Step 1 - Egg stimulation: Patient is given fertility medications to stimulate the production of egg. To increase the success rate of the treatment multiple eggs are needed. Usually it not advisable to rely on single egg for which the doctor gives fertility drug to increase the production of eggs.
Depending upon the patient's response medications are advised. There are various protocols for egg stimulation.
Egg stimulation is guided by Transvaginal ultrasound to examine ovaries, blood samples and to determine the level of hormones.
Step 2 - Egg Retrieval: Imaging ultra sound is used to retain ovarian follicles with the help of hollow needle. Retrieval of egg is followed with minor surgery
Complete procedure takes about half an hour. The follicular fluids are carefully seen by embryologist to trace the proof of available eggs.
After the entire procedure eggs are preserved in incubator till insemination.
Step 3 - Culture of Fertilization and Embryo: For insemination male sperm sample is collected
Eggs are mixed with the sperms and stored in laboratory
If there are chances of low probability of fertilization, ICSI can be considered.
To enable fertilization single sperm is infused in the egg Fertilized eggs are considered as embryos only after the confirmation by an embryologist.
Step 4 - Transfer of egg and quality of Embryo: Embryo transfer is the quickest method done in overall treatment
Embryo is assessed on the basis of age and quality.
Doctor is asked to keep the full history of the patient starting from age to previous treatment, but the end decision is taken by patient itself
Under normal situation, doctor suggests transferring single embryo with blastocyst and rest of them are preserved. Transfer of one high quality embryo decreases the risk of triplets or twins.
During transferring, doctor inserts Cather and pushes pre determined embryos in the female uterus
This method is done under guidance of ultra sound. Patient is advised to take rest for 5- 6 hours after it
After this method, pregnancy test is conducted to know the exact situation.

The average cost for test tube baby in India would be around Rs. 200000 to Rs. 400000. However, there are some government recognized hospitals like AIIMS and few others charge as low as Rs. 70000 to Rs. 85000 Other than this, a few private clinics charge on per cycle basis. Whereas some offering multiple IVF cycle packages. Always discuss with the clinic, the payment options you can get before starting the treatment.
Patient’s age : Success rates decreases as the age of the women increases especially above 40 years.
Embryo Quality : Embryos having chromosomal and genetic problems are extremely weak and are not suitable for this treatment
Ovarian Response : If the ovaries do not react positively to the medications and are unable to produce multiple eggs.
Implantation problems : Around 50% of the cases fail due to implantation problems. This can happen when the embryo stops growing unknowingly.
Sometimes women find implantation to be painful. To conduct the implantation without pain, they are given pain killer tablets and injections.
Usually IVF patients experience irregular periods or spotting after two weeks of implantation. As the embryo moves into the uterus it causes bleeding and pain.

In this case IUI (Intra-uterine Insemination) or IVF is required for a mother to get pregnant 6) Genetic Testing: suppose a partner is suffering from certain disease, and if they have fear that the disease can be passed to the new born baby, then IVF technique is needed 7) Death of partner : IVF treatment is very helpful in the case if the partner is not alive, and the couple has stored its sperm or egg before 8) Surrogacy : surrogacy means, if the female partner is unable to conceive a child, then the baby is carried in the womb of another lady. IVF is useful so that sperm or egg produced by another partner can be transferred to surrogate uterus 9) Egg freezing: in case of egg freezing egg stimulation and egg retrieval is needed.

Patient should understand the chances of conceiving and this depends upon various factors, from which the most important are:
As you cannot change your age or past history but you can make your chances positive of being pregnant by getting nothing but the best treatment under the hands of IVF experts.
Assisted reproductive technology (ART) includes many advanced techniques that increase your chance of conceiving through test tube baby procedure.
1) Intrauterine Insemination (IUI):
During this treatment, the sperm is directly placed in the woman’s uterus using a long narrow tube. It is mostly used in cases where the sperm count is low or has low mobility. It is also used for women who have a defect in the cervix.
2) Intracytoplasmic sperm injection (ICSI):
ICSI is used in cases of severe male-factor infertility. A single sperm is injected directly into an egg by the embryologist to increase your chance to conceive successfully.
3) Donor egg or sperm:
Donor eggs are used when the eggs produced by the woman is not healthy enough for fertilization. They are also used by the woman who has her ovaries removed, are a carrier of genetic diseases or has undergone radiation or chemotherapy.
Donor sperm is used when the person is unable to produce any sperm or has a very low sperm count. Also, people having genetic diseases prefer using donor sperm.
A surrogate is a person who carries the child of another couple in her uterus and gives birth to the child but is not the biological mother of the child. The couple may have to use a surrogate for several reasons such as the woman does not have a uterus, there are some issues with the uterus that makes it hard for her to conceive or has some medical issues that make the pregnancy dangerous for the woman.
5) Gamete intrafallopian transfer (GIFT):
During this procedure, the sperm and the eggs are combined in the laboratory and are straightaway transferred to your fallopian tubes through a small incision in your abdomen. The eggs are fertilized inside your body and the implantation of the embryo takes place naturally.
6) Zygote intrafallopian transfer (ZIFT):
During ZIFT procedure, the eggs are mixed with your sperm in the laboratory but the doctor waits for them to fertilize before transferring the embryo to the fallopian tube with the help of a small incision in the abdomen.
7) Cytoplasmic transfer:
This procedure involves the transfer of the content of a fertile egg from a donor to the infertile egg of the patient along with the sperm.
Ovarian hyperstimulation syndrome – During the procedure of test tube baby, there is a risk of ovarian hyperstimulation syndrome due to the use of fertility drugs such as human chorionic gonadotropin (HCG).
The drugs may cause the ovaries to overreact, due to which they swell up and are painful. The patient experiences bloating, vomiting, nausea, heartburn, loss of appetite, diarrhea and mild abdominal pain which may last for about a week.
It is quite rare, but in severe cases, it may cause shortness of breath and rapid weight gain. However, the symptoms may last for several weeks if you have conceived.
Do not let this complication scare you as most of the cases are mild and can be easily treated.
Complications during egg retrieval - During the process of egg retrieval, the doctor uses a hollow needle to collect the eggs which may cause infection, bleeding or damage to the blood vessels, bowel or bladder.
Ectopic Pregnancy - Ectopic pregnancy occurs if the fertilized egg implants itself outside the uterus in the fallopian tube. This can happen to around 2-5% women who have conceived with the help of test tube baby procedure. As it is not possible for the fertilized eggs to survive outside the uterus, the pregnancy has to be terminated.
Miscarriage - The chances of miscarriage in women who have conceived by the procedure of test tube baby using fresh embryos is similar to women who have conceived naturally. But the rate of miscarriage increases slightly if frozen embryos are used or if the age of the women is on the higher side.
Multiple births - It is one of the major complication of test tube baby process as it increases the risk of multiple births. This happens when more than one embryo is transferred to the uterus. Multiple births can cause lots of complications such as miscarriage, obstetrical complications, early labor and low birth weight.
Early labor and low birth weight - According to the researchers, the process of test tube baby may slightly increase the risk of the baby being born early or having low birth weight.
