IVF

Overview of IVF in India

An egg is released from the ovary into the fallopian tube during a typical menstrual cycle. Fertilisation occurs in the fallopian tube, and the fertilised egg will remain there for several days, dividing and eventually forming an early embryo. Several days later, the embryo finally travels through the fallopian tube into the uterus and attaches to the uterine wall.

In vitro fertilisation is considered a bypass of the fallopian tube. The ovaries are stimulated through the use of injectable fertility medications to produce multiple eggs. Various transvaginal ultrasounds and blood tests, performed while the follicle is maturing, will allow for tracking of when ovulation will occur. Once that happens, the eggs are retrieved through the vagina with the help of a minor procedure involving a mild anaesthesia. The eggs are placed in a petri dish containing human sperm.

The following day, the eggs are inspected to determine whether fertilisation has taken place successfully. In that case, they are placed in a petri dish where they are allowed to divide and develop into early embryos. At some point, after a few days, one or more embryos are positioned in the woman's uterus in a straightforward procedure that usually does not feel any worse than a Pap test. The IVF laboratory personnel examine the extra embryos. When they are viable they can be frozen and kept for use by the couple later.

In vitro fertilisation (IVF) is a special reproductive technology whose first successful case was realised in England in 1978. When first developed, IVF could be utilised only to treat infertility that resulted from blockage of the fallopian tubes. Nowadays, IVF has evolved into an effective therapy for every reason of infertility in cases where the simpler treatment has failed or cannot be used. The success rate of IVF is now significantly higher compared to the past few decades. The IVF success rates of many clinics have increased to 50 per cent or more, offering a favourable prognosis.

IVF in India for various treatments to Indian patients is between USD 2,100 to 2,800. The cost for International patients is from USD 3,150 to USD 3,850. The Cost of IVF treatment can fluctuate depending on numerous factors, such as the patient's medical conditions, the medications they take, the type of IVF cycle treatment, and the facility's location in India.

What is IVF?

A form of assisted reproductive technology (ART) called in vitro fertilisation (IVF) involves fertilising an egg and sperm outside of the human body. IVF is a complicated procedure that entails taking eggs out of the ovaries and manually fertilising them in a lab by combining them with sperm. A few days following fertilisation, the fertilised egg—now known as an embryo—is inserted into the uterus. When this embryo inserts itself into the uterine wall, pregnancy results.

Types of IVF:

Conventional IVF

One of the first questions one might have when it comes to fertility treatment via IVF is how does it work; the answer to that question is simple the treatment involves growing multiple egg follicles, surgically removing them and thereafter fertilizing it with the sperm in a sterile laboratory environment. Subsequently the embryos are placed into the patient uterus or cryopreserved. Traditional IVF is usually an advised option to only those, who have not been able to conceive using lesser medical intervention methods like Intrauterine Insemination (IUI) and Timed Intercourse.

Conventional Single Embryo Transfer IVF is thought to be the optimal option, in the following cases:

• Ladies whose Fallopian tubes are severely injured
• Male infertile factor and unexplained infertility
• Premature pregnancy loss in women
• Same-sex couples with donor eggs and/or sperms

Mini IVF

Mini IVF/Minimal stimulation IVF includes a more gentle and holistic process of the traditional IVF treatment. Mini IVF uses minimal oral drug and injection to naturally encourage the ovaries to yield a healthy number of what is referred to as high-quality eggs in a single cycle cycle. The operation will seek to offer an alternative to the conventional treatment, which is less stressful and less painful and less invasive. 

The use of minimal stimulation IVF is applicable to persons having a block down or damage of the Fallopian tubes or those who have a low ovarian reserve.

Mini IVF Treatment is regarded as the most appropriate one when:

• Women, who have poor ovarian reserve
• Those women who do not respond satisfactorily to the Conventional IVF
• Women, who would like a more natural touch 
• Nevertheless, women who are more than 35 years old

Natural IVF

The natural cycle IVF revolves around the concept that many eggs and embryos do not equal a greater pregnancy possibility. The natural IVF technique entails the collection of one excellent quality egg that a patient naturally produces every month to aid its in vitro fertilisation and thereafter being returned to the uterus to implant. The standard procedure of IVF medicine usually includes the following steps:  

• The production of natural eggs is observed by routinely accessing their blood and performing an ultrasound examination.
• Ovulation in egg is induced when the egg has attained a mature state
• The process of egg retrieval is done through an outpatient surgery
• Other IVF procedures are performed such as fertilisation of eggs and embryo growth in a controlled laboratory environment and are transferred in case they are considered good quality.

Different Types of IVF and Fertility Procedures

Although these are the three big categories of In-Vitro Fertilization procedures, there are still various infertility treatments that one can deliberate on depending on patient requirements. For instance: 

The better and more comfortable version of normal in vitro fertilization is needle-Free IVF, which is painless.

Ovarian Rejuvenation Therapy -This is an easy process, which returns home an ovarian activity to a woman.

In Vitro Maturation - it is the method of obtaining immature oocytes and maturing them in a special culture.

Intracytoplasmic Sperm Injection - this kind of examining a sperm stuns the sperm, cuts off the tail and inserts them into an egg through a technique referred to as Injection

Frozen Eggs- egg Freezing or fertility preservation or cryopreserving involves the collection of the eggs of a woman, and having them preserved to be fertilized later.

Procedure:

Birth control pills or estrogen

Your doctor could recommend oestrogen or birth control tablets before IVF therapy. This is used to regulate the time of your menstrual cycle and prevent the formation of ovarian cysts. During the egg retrieval process, it enables your healthcare professional to optimise the quantity of mature eggs and manage your therapy. While some women are prescribed only oestrogen, others are prescribed combination birth control pills that contain both oestrogen and progesterone.

Ovarian stimulation

In a healthy individual of reproductive age, a batch of eggs begins to mature every month during each natural menstrual cycle. Only one egg usually develops to the point where it can ovulation. In that group, the remaining immature eggs break apart.

You will take injectable hormone drugs during your IVF cycle to promote the complete and simultaneous maturation of all the eggs in that round. This implies that you might have multiple eggs rather than just one, as in a natural cycle. Your medical history, age, AMH (anti-mullerian hormone) level, and how you responded to ovarian stimulation during prior IVF cycles will all be taken into consideration when determining the kind, amount, and frequency of drugs that are recommended.

The other steps in the ovarian stimulation process include:

Monitoring: Results of the medications on your ovaries are reported by ultrasounds and blood amount of hormones. The monitoring should be done after every two weeks, daily or a few days. The majority of stimulations take eight and 14 days. Healthcare providers check your uterus and ovaries by using ultrasound during monitoring appointments. The eggs are so small that they cannot even be seen through ultrasound. 

However, your health workers will gauge the volume and quantity of the developing ovarian follicles. The follicles are tiny sacks inside your ovaries and each is expected to house one single egg. Each follicle contains an egg showing its maturity by its size. A majority of follicles that are more than 14 millimeters (mm) include a mature egg. The eggs found in the follicles that are not greater than 14 mm have a better chance to be immature and will not fertilise.

Trigger shot: A "trigger shot" is administered to complete the maturation of your eggs in preparation for egg extraction when they are ready for ultimate maturity, as assessed by your hormone levels and ultrasound. The trigger injection should be given precisely 36 hours before the time you have set for egg retrieval.

Egg retrieval

• The physician inserts a thin needle into your vagina with the help of the ultrasound in both ovaries. There is a deflation machine that is linked to the needle which is used to withdraw your eggs via each follicles.
• Your eggs are put into a dish with special solution. The dish is later placed in an incubator (controlled environment).
• A form of mild sedation and medications are administered to ease any discomfort in this procedure.
• The egg retrieval takes place 36 hours after the last shot of the hormone, which is called a trigger shot.

Fertilization

All of the mature eggs will also be fertilized in the afternoon of the day after your egg retrieval procedure using intracytoplasmic sperm injection, or ICSI by the embryologist. This implies that each mature egg will be injected with sperm. ICSI treatment is not possible on immature eggs. The undeveloped eggs will be put into a dish containing sperms and food. Eggs which are not mature will hardly complete maturation in the dish. In case one of the immature eggs matures, it can be fertilized by placing the sperms in the dish.

Previously, an average of 70 percent of fully developed eggs will be fertilized. As an illustration, when 10 mature eggs are retrieved approximately seven will expect to be fertilized. When this is successful, the embryo is conceived.

In case of over plenty eggs or in order not to fertilize the entire eggs; some of the eggs can be frozen before fertilization, to be used in future.

Embryo development

Your embryos' development will be closely monitored throughout the next five to six days.

For your embryo to be ready for transfer into your uterus, it must overcome several obstacles. The blastocyst stage is reached by approximately 50% of fertilised embryos. The best time to transfer to your uterus is at this point. For instance, three or four of the seven fertilised eggs may reach the blastocyst stage. Usually, the remaining 50% are not advanced and are discarded.

On the fifth or sixth day following fertilisation, all viable embryos will be preserved for use in subsequent embryo transfers.

Embryo transfer

Fresh embryo transfers and frozen embryo transfers are the two types of embryo transfers. Your healthcare professional can discuss with you the use of frozen or fresh embryos and determine which option is ideal for you based on your specific circumstances. The transfer procedure is the same for both fresh and frozen embryo transplants. The name implies the primary distinction.

When you have a fresh embryo transfer, your embryo is placed in your uterus three to seven days following the egg retrieval process. This embryo is "fresh" because it hasn't been frozen.

In a frozen embryo transfer, donor eggs or frozen embryos from an earlier IVF round are thawed and placed into your uterus. Due to practical considerations and the increased likelihood of a live birth, this procedure is more frequently used. Years may pass following egg retrieval and fertilisation before frozen embryo transfers take place.

You will take oral, injectable, vaginal, or transdermal hormones to prime your uterus to receive an embryo as part of the initial phase of a frozen embryo transfer. This typically consists of six days of injections after 14–21 days of oral medicine. During this time, you will usually have two or three appointments to measure your hormone levels with a blood test and to have your uterus checked with ultrasound. You will be scheduled for the embryo transfer procedure when your uterus is prepared.

Using fresh embryos follows a similar procedure, with the exception that embryo transfer takes place three to five days after the embryo is extracted.

There is no need for anaesthesia during the straightforward embryo transfer process. It feels like a Pap smear or pelvic exam. A tiny catheter is passed through the cervix into the uterus, and a speculum is positioned into the vagina. One or more embryos are contained in a syringe connected to the other end of the catheter. The catheter is used to inject the embryos into the uterus. Usually, the process takes less than ten minutes.

Pregnancy

When the embryo inserts itself into the lining of your uterus, pregnancy results. Nine to fourteen days following embryo transfer, your doctor will conduct a blood test to check for pregnancy.

The same procedures are followed if donor eggs are being used. The egg donor will perform both ovarian stimulation and egg retrieval. The embryo is delivered to the intended pregnant carrier (either with or without various fertility drugs) following fertilisation.

Before beginning IVF therapy, several key considerations should be taken into account. It's crucial to speak with your healthcare professional to gain the most excellent understanding of the IVF procedure and what to anticipate.
