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?

Frozen Embryo Transfer or FET is an extremely effective method to conceive a pregnancy. Recent studies have proved that there is a increased chance for pregnancy when the embryos, which get used are frozen and get placed inside the uterus at a time right after the ovaries are stimulated. Still, certain issues can arise with the transfer of frozen embryo, such as:

A Thin Lining of the Uterus
Research has shown that there are not many women who get pregnant if the lining in their uterine does not tend to thicken enough. It is not clear exactly why this problem occurs in most women and moreover there is no sure shot treatment to make the lining of the uterine thick. The experts on fertility would try out different methods like increasing the amount of estrogen or change the way how estrogen is given. There are other instances when women might be given supplemental medicines, while for some, the problem will continue to exist.

What Should Be Done In Case The Problem Persists?

In case the problem continues for some women, then there are certain approaches which experts might look to adopt. The first one is to cancel the transfer of embryo and try once again at any later stage, that too with a different treatment method.
The second option which they could think of is to go ahead with the transfer, wherein they might feel that a thin lining does not necessarily mean that it is impossible for a woman to get pregnant but definitely the efficiency would be reduced.
One last option is to make use of the opportunity for undergoing additional tests which would help them to assess the ability of the uterus to allow implantation of the embryos.
Unexpected Ovulation
For enabling the embryos to get implanted into uterus, placing them very precisely and at the appropriate time is important. This is regarded as the window of implantation. The time taken, is based on the time frame since progesterone reaches the lining of the uterine.

Doctor knows the exact time to place the embryos, right from the time he or she instructs a woman to start having progesterone supplements. In case a woman was to ovulate, the production of progesterone would begin earlier than the normal time and would lead to the shift of the window of implantation. As identifying the correct time of ovulation is almost impossible, so that would lead to some sort of uncertainty into the timing.

Due to this reason, there are doctors who would use medication in order to prevent unexpected ovulation from occurring. Generally an injection called Lupron is usually used as medication.

Timing for the Embryo Transfer is Inappropriate
This is a problem related to early ovulation. There are case when the implantation window is shifted, still the timing of the transfer becomes accurate. Recent studies have shown that quite a nominal percentage of women might have a window of implantation, which could be either earlier or later than normal time. A test called the Endometrial Receptivity Array can help determine at what time is the window of implantation open.

Frozen Embryo Transfer - Complications Associated With It!

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

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?

The fallopian tubes are not mere passages for the egg to travel from the ovaries to the uterus. It is here that conception occurs and hence healthy fallopian tubes are essential for the fertilization of an egg. 

Damaged fallopian tubes are the most common cause of infertility. This damage can fall under three categories. 

 Blocked fallopian tubes
 One blocked and one open fallopian tube
 Tubal scarring

The third is usually an effect of pelvic infections or natural healing after a pelvic surgery. Sadly, in most cases, this condition is discovered only after infertility has been diagnosed. Other causes of fallopian tubal scarring include:

 Stds such as chlamydia trachomatis and neisseria gonorrhea
 Adhesions caused by ruptured ovarian cysts
 Appendicitis
 Peritonitis
 A history of ectopic pregnancies

Fallopian tubal scarring has no recognizable symptoms. Chronic pelvic pain is the only known symptom of this damage and that too can be seen only in severe cases of tubal scarring. On diagnosing infertility, your doctor will perform one of these tests to determine the condition of your fallopian tubes.

 Hysterosalpingogram: this is a type of x-ray. Your doctor will open the vagina with a speculum and inject a liquid into the uterus with the help of a catheter. If the liquid does not pass through the fallopian tubes, it is said to be blocked. This however, does not say much about tubal scarring.
 Laparoscopy: a small incision is made below the belly button and a slim, flexible tube with a camera is passed through the incision. This gives your doctor a clear view of the condition of your fallopian tubes. A laparoscopy can also be used to rule out other causes of infertility such as endometriosis or blocked fallopian tubes. 

Treatment for infertility caused by tubal scarring is of two types:

 Surgery: this is suggested in cases where tubal scarring is minimal. Depending on the intensity and placement of scar tissue, your doctor may decide to perform one of many types of surgeries. He may choose to remove the scarred section of the fallopian tube, create a new opening (in case of blockages) or rebuild the damaged edges of the fallopian tubes.
 In vitro fertilization (ivf): women with badly scarred fallopian tubes usually have poor chances of conceiving naturally. Hence, ivf is the preferred treatment route. However, your doctor may still advise you to undergo surgery and remove the damaged tubes prior to ivf to prevent the tubes from filling with fluid.

Tubal Scarring and Infertility

What are the factors that make a woman fertile? + The most effective way to address infertility

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.
