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?

Factors that determine the success of your IVF procedure

IVF or In Vitro Fertilization is a process wherein an egg is fertilized by a sperm in a laboratory dish to form the embryo (baby's first cell) which after growth in artificial medium in the lab is transferred into the uterus of women, In general, a blood sample is collected to determine whether you're pregnant or not about 10-14 days after the eggs are retrieved.

Coming to the success of the procedure, a number of factors are at play and these are:

The age at which you get pregnant

A factor that plays a role in influencing your chances of experiencing success in your IVF procedure is the age at which you opt for this procedure. The lower your age, the chances that you may get pregnant and deliver a healthy child using your own eggs witness an increase. On the other hand, if you're aged 41 and above, or your egg reserve is very low donor eggs are the most preferred option as they help to increase your prospects of meeting a success.

Lifestyle habits

Certain lifestyle factors can significantly affect your prospects of getting pregnant through this route. Smoking can reduce your prospect of success using this procedure by about 50%. It can cause you to have lesser number of eggs retrieved during the procedure while increasing instances of miscarriages. Likewise, obesity, alcohol use, consumption of excessive caffeine and drugs can adversely affect your chances of getting pregnant using IVF.

Cause of Infertility

If your supply of eggs is normal, success rate using IVF is high. Women who suffer from the problem of endometriosis experience lesser chances of getting pregnant than women who have unexplained fertility.

Reproductive history

IVF success rate chances are higher if you've delivered a baby previously using IVF.

Embryo status

Embryos that are better developed with good grade stand a higher chance of experiencing success than less developed embryos. More importantly, not every embryo is able to survive the development process.



What are the factors that determine the success of your IVF procedure?

Intrauterine insemination (IUI) and in vitro fertilization (IVF) are two commonly used methods of fertility treatment, which increase a couple s chance of becoming pregnant.

The Procedure

IUI- IUI is a procedure during which processed and concentrated motile sperm are inserted directly into a woman s uterus. This procedure is timed according to a woman s ovulation, and may be performed one to two times in the days immediately following the detection of ovulation. After ovulation a woman s egg is picked up by the fallopian tube and waits there for the sperm. Since the IUI procedure deposits higher concentrations of good quality sperm close to where the egg is waiting, the chances that the egg and sperm will find one another are increased.

IVF- IVF is the most successful method of fertility treatment utilized today to help couples to conceive. The basic components of the IVF process include stimulation of the ovaries to produce multiple eggs at a time, removal of the eggs from the ovary (egg retrieval), fertilization of the eggs in the laboratory, and subsequent placement of the resulting embryos into the uterus (embryo transfer). The chance of pregnancy from IVF depends primarily on the age of the woman, the cause of infertility, and factors related to the quality of the IVF laboratory.

Success Rates

IUI Treatment: There is a marked difference between IVF and IUI pregnancy rates. IUI has a success rate between 5% and 20%, but it can even be as low as 1-2 %, depending on the woman s age and fertility levels. The chances of conceiving through IUI is higher if fertility drugs are administered along with the treatment.

IVF Treatment: IVF has a high success rate   between 20% and 35% and it can even go as high as 40%. This may not seem like a lot, but it is very high, considering that an average young and fertile couple has only a 15-20% chance to conceive in a month. It is important to understand what IVF and IUI success rates mean and the factors that affect it before deciding on a fertility treatment. You can also use any reliable online IUI vs IVF comparison tool to determine your approximate success rates with each of these treatments, depending on your age, lifestyle, and medical history.

You should use online sources of information to understand more about fertility problems, how age affects fertility levels, and whether freezing your eggs is a good option for you. However, discuss all these issues with your doctor to ensure that you have the right information and that you have understood it correctly. Fertility specialists provide you with personalized fertility plans based on your health which is why you should always talk to them before you make any decision.

IVF or IUI - Which One Should You Opt for?

It is as important for the man as it is for the woman to undergo certain tests before the IVF cycle is started. Fertility is not only an issue for a woman, but it also might be for the man in question. There are certain tests that need to be conducted on men before they can gear up for IVF:

1. Semen Analysis: One of the most important tests for male infertility is semen analysis. Sometimes, a man may be completely healthy, but his sperm production could be of poor quality. Semen analysis is done to provide an accurate evaluation of sperm number, the ability to move (motility), size and shape (morphology), as well as the consistency and volume of the sample collected.

2. Binding Test: Sometimes agglutination occurs where the sperms might stick to each other by their heads or tails. Sperm antibodies might cause this problem. The IVF treatment's success might be compromised if this happens. A simple binding test is done to determine this.

3. Trial Wash: This is also known as sperm wash. It is mostly done to remove chemicals from the sperm. Not doing a sperm wash might end up affecting the later stages of the IVF treatment. In this process, the misshapen and immotile sperm is separated so a clean sample of motile and healthy sperm can be collected.

4. TUNEL Assay: Since sperms build up about half of a child's genetic makeup, a TUNEL Assay or 'sperm DNA test' is required. This test is done to measure the sperm population that have fragmented DNA. Negative impacts on genetics can hamper the success of the fertility treatment.

TUNEL Assay is usually recommended to men with:
a) Leukocytes detected by the sperm analysis
b) Age approaching 50
c) A history of diabetes II type or prostatitis
d) Exposure to chemicals or prolonged heat at workplaces

5. Screening for Infectious Diseases: This test is done for both the partners to check for diseases like AIDS, Hepatitis C, and so on.

Tests Suggested for Men Before IVF

Intracytoplasmic Sperm Injection i.e. ICSI is different from conventional IVF i.e. In Vitro Fertilization because a single sperm is selected by the embryologist to be injected by a needle into the egg rather than a dish with many sperms placed near the egg so that the fastest swimming sperm enters it. Once the sperm is injected directly into the egg, it fertilizes, after which the embryo is transferred into the womb or uterus. 

Your doctor might recommend ICSI treatment for you if you have an extremely low sperm count resulting in infertility or other medical sperm conditions such as poor motility or poor morphology. It may also be suggested if prior attempts at IVF procedures have failed in fertilizing the egg or the fertilization rate is extremely low. You must also consider ICSI treatment if you resort to embryo testing or if the sperm needs to be collected from the epididymis or testicles surgically. 

However, you must keep in mind that if your partner has a genetic problem resulting in low sperm count, it could be passed on to your child, if you decide to use your husband's sperm for this process.

Success Rates of ICSI:
The success rate of ICSI treatment depends on your age and your fertility problem. Your eggs are healthier when you are young and as you age, chances are that they will become less healthy.
1. 35 per cent if you are under 35 years of age
2. 29 per cent if you are between 35 to 37 years of age
3. 21 per cent if you are between 38 to 39 years of age
4. 14 per cent if you are between 40 to 42 years of age
5. 6 per cent if you are between 43 to 44 years of age
6. 5 per cent if you are above 44 years of age

Advantages of ICSI Treatment:
Intracytoplasmic Sperm Injection gives you a chance to conceive a child genetically when most other options are exhausted. Males may be unable to ejaculate on the day the eggs are collected due to anxiety. ICSI proves to be advantageous because sperm may also be surgically extracted for this process. It is extremely helpful for those couples who suffer from unexplained infertility. However, one of the most important factors is that ICSI treatment does not affect your child's physical or mental health.

Infertility is the inability to get pregnant after a year of unprotected intercourse. Both men and women can be infertile.

In about one-third of cases, the cause of infertility involves only the male.

In about one-third of cases, the cause of infertility involves only the female.

In the remaining cases, the cause of infertility involves both the male and female or no cause can be identified.

Women are born with a finite number of eggs. Thus, as the reproductive years progress, the number and quality of the eggs diminish. The chances of having a baby decrease by 3% to 5% per year after the age of 30 and this reduction is noted to a much greater extent after age 40.

Female infertility can also be caused by a number of factors including:

1. Damage to fallopian tubes

Damage to the fallopian tubes can prevent contact between the egg and sperm. Pelvic infections, endometriosis, and pelvic surgeries can lead to fallopian tube damage.

2. Hormonal causes

This can lead to ovulation disorders which prevent the ovaries from releasing eggs such as in polycystic ovary syndrome ,  hyperprolactinemia or disorders of the thyroid gland - hyperthyroidism / hypothyroidism, can interrupt the menstrual cycle and cause infertility.

3. Cervical causes

A small group of women may have a problem in which the sperm cannot pass through the cervical canal. Whatever the reason is , this problem may be treated with intrauterine inseminations.

4. Uterine causes

Abnormal anatomy and distortion of the uterine cavity due to the presence of polyps and fibroids or problem with the endometrial lining can lead to failed implantation of the embryo.

Endometriosis occurs when endometrial tissue grows outside the uterus - often affecting the function of the ovaries, uterus, and fallopian tubes.

5. Primary Ovarian Insufficiency:

Also called as Premature Menopause, when the ovaries stop working prematurely before the age of 40. Certain conditions are associated with early menopause like immune system diseases, radiation or chemotherapy and smoking.

Causes of male infertility may include:

1. Abnormal sperm production or function due to various problems, such as undescended testicles, genetic defects, health problems including diabetes, prior infections such as mumps, trauma or prior surgeries on the testicles or inguinal region.

2. Problems with the delivery of sperm, due to sexual problems, such as premature or retrograde ejaculation, certain genetic diseases, such as cystic fibrosis, structural problems, such as blockage of the epididymis, or damage to the reproductive organs.

3. Overexposure to certain chemicals and toxins, such as pesticides, radiation, tobacco smoke, alcohol, frequent exposure to heat can elevate the testicular temperature, impairing sperm production.

4. Damage related to cancer and its treatment, including radiation or chemotherapy for which timely cryopreservation can be done for future use.

5. Unexplained infertility, In approximately 20% of couples the cause cannot be determined using the currently available methods of investigation.

Why is IVF the best way to treat infertility in women?

Conception is a complicated process that depends on upon many factors:

On the production of healthy sperm by the man and healthy eggs by the woman

The sperm's ability to fertilize the egg when they meet.

The ability of the fertilized egg (embryo) to become implanted in the woman's uterus

IVF (or in-vitro fertilization) is a lab procedure where the sperm and the egg are combined in a dish (where fertilization takes place) and is followed by transferring the embryo (the fertilized egg) into the uterus. It is increasingly being used as a method to conceive as it has been established as a safe procedure that helps bypass a number of complications women may face while conceiving such as ovulation problems and issues with the fallopian tube.

Even women who face issues such as PCOS, endometriosis, and premature ovarian failure can conceive through this process. Moreover, IVF has been in practice since 1978 and has a safe track record. The success rates of IVF are high as well, making it a preferred procedure for couples who suffer from fertility problems. Unexplained infertility can also be treated with the help of this procedure.
