Which IVF protocol is the best

Which IVF Protocol is the Best?

In order to undergo the IVF process, there are several IVF protocols that can be used to stimulate the ovaries by the use of certain medications and prepare them for in vitro fertilization (IVF). This process is done in order to reach an optimal number of eggs to be fertilized and make healthy embryos so that at least one pregnancy occurs.

There are different types of IVF protocols and each of them can be suitable for certain patients. For choosing the best IVF protocol, you need to consult with your fertility doctor to review your medical records (woman’s age, response to the medication and the outcome of previous attempts) and decide which protocol is right for you.

IVF Protocols

Antagonist Protocol (Short Protocol)

This is the most commonly used protocols for IVF. It is effective for most of the patients and contains the lowest number of injections. In this protocol, you will be informed to use birth control pills before starting the IVF cycle. For 10 days you will be taking follicle-stimulating hormone (FSH) and will have luteinizing hormone (LH) injections.

Around the day 5, the Gonadotropin-Releasing Hormone (GNRH) antagonist is used in order to prevent premature ovulation. Your doctor may use “Lupron trigger” or “dual trigger” medicines to stimulate the maturation of the eggs before retrieval process begins. In this way the risk of Ovarian Hyper-Stimulation Syndrome (OHSS) decreases significantly.

Lupron Down Regulation (Long Lupron Protocol)

This protocol is mostly used in the younger patients or those who had poor-quality embryos in their previous protocols. You will be prescribed to take birth control pills before starting the cycle of IVF. On the third week your doctor will order an injectable medication called Lupron. By undertaking Lupron injections, your pituitary gland temporarily stops secretion of FSH and LH hormones. Injections can control the cycle and prevent premature ovulation of the follicles.


The Micro-dose Lupron Flare Protocol

The micro-dose Lupron is prescribed for those patients who had a poor response to their previous protocols due to their high reproductive age or low ovarian reserve. The flare protocol is used to make the ovaries quickly respond to the stimulation and produce enough mature eggs to be used in the IVF process. The lower dose of Lupron stimulates the body’s natural FSH production instead of suppressing it. Taking micro-dose Lupron for stimulation phase continues until the injection of the Human Chorionic Gonadotropin (HCG) trigger. This protocol usually makes the IVF process work by enhancing the response speed of the ovaries.


Estrogen Priming Protocol

Women who respond poorly to the short protocols and have low ovarian reserve may enhance their ovaries response by using this protocol. Estrogen Priming Protocol synchronize more follicles for retrieval. For this aim, your fertility doctor may suggest you to undergo an estrogen medication and probably a few days of GNRH antagonist before you start the IVF cycle.

Mini-IVF or Micro-IVF Protocol:

Some experts believe that minimal stimulation may offer some benefits instead of using traditional treatment. The related doctor may prescribe fertility pills or medications in very low dosage in order to retrieve just one or two eggs each time. The disadvantage of using this protocol is that it produces just a few healthy eggs and it needs undergoing more egg retrievals for achieving the goal of getting pregnant.


What is a typical IVF protocol?

What is a typical IVF protocol

The most typical IVF protocol is the Antagonist or Short Protocol. This method involves the fewest number of injections and it is a mostly effective protocol for all patients. In this protocol, you may be recommended to use birth control tablets before starting an IVF cycle. You need to use follicle-stimulating hormone (FSH) and luteinizing hormone (LH) injections for 10 days. From around the fifth day, you should add Gonadotropin-Releasing Hormone (GnRH) antagonist in order to prevent premature ovulation.

Before egg retrieval, your doctor may prescribe a “Lupron trigger” or “dual trigger” to stimulate the final maturation of the oocytes and get them ready to be harvested. It also decreases the risk of Ovarian Hyperstimulation Syndrome (OHSS). This protocol is usually used in younger patients or those who have not seen a good response from the other IVF protocols.  By the third week, your doctor will prescribe you an injectable medication called Lupron. This medication temporarily stops the pituitary gland in the brain from releasing FSH and LH. By this method, the FSH and LH level from the injectable will control your cycle and prevent premature ovulation of the follicles.

Which is better; short or long IVF protocol?

Both short and long protocols of IVF are practical ways for stimulating egg follicles’ growth and retrieving them for insemination. Long IVF protocol which is known as GnRH agonist long protocol will take about 4-5 weeks. You will start taking medications on the 21st day of your menstruation cycle which is known as ‘down regulation’ and aims to suppress ovarian function. Typically, after 10-14 days of suppressing the ovaries, the second type of medication which is gonadotrophins (typically FSH or hMG) will be started and it will be administered for 12-14 days. Gonadotrophins stimulate follicles growth and you will be checked by ultrasound every 3-4 days during this process to monitor the response of follicles to the medications and determine the time of egg retrieval.

A short protocol will take 2 to 3 weeks and usually consists of 10-12 days of medication before egg retrieval. In the short protocol, there is no suppression of ovarian functions. You should take Gonadotrophins (FSH or hMG) for about 10-12 days and while the follicles are growing, you need to be checked by your doctor through internal scans every 3-4 days.

The long protocol was the first IVF protocol that was used for patients and after that short protocol was developed. Studies have shown that there is little difference in the results of long and short IVF protocols. However, a short IVF protocol is less prone to Ovarian Hyperstimulation Syndrome (OHSS). There is no fixed protocol for all patients and treatment plans should be arranged according to the individual’s medical history and follicles prognosis. TebMedTourism’s doctors will carefully consider the medical condition of each patient and then arrange the best IVF protocol.

What is the best IVF Protocol?

It is fair to say that the best IVF protocol is neither maximal nor minimal, instead of them, it should be optimal based on the patient’s age, medical history, basal follicle count, Anti-Mullerian Hormone (AMH) levels, and family building aims. Before starting the IVF cycle, you have to consult with your fertility doctor to find out which protocol best fit your condition.

What is the best IVF protocol for a poor responder?

What is the best IVF protocol for a poor responder

To maximize the IVF success rate, it is preferred to get multiple high-quality eggs. However, some women are poor responders to ovarian-stimulating drugs. After taking stimulating medications, they might mature a low number of follicles that lower the chance of IVF success. Therefore, women with the low ovarian response should be treated with a special IVF protocol that helps them mature more follicles.

In long IVF protocol, some women are “over-suppressed” or are poor responders due to some other reasons. A “stop Lupron” protocol is one of the options to get a better ovarian response when using stimulating medications. In this protocol, Lupron will be used at the lower dose of 5 units daily instead of using 10 or 20 units, and then it is completely stopped after the woman gets her period.

“Flare protocol” is another IVF protocol that is started on the second day of the cycle and tries to take advantage of an initial “flare-up” response of FSH and LH which are released from the woman’s pituitary gland. In this protocol, birth control pills are usually used for one month before the flare in order to not have any leftover cysts because they can be reactivated by the high LH level. Continuing Lupron for more than 3 days, suppresses the pituitary gland so that it has a low output of FSH and LH. The aim of this protocol is that Lupron causes the release of a large amount of FSH and LH that will suddenly start (flare-up) the follicles and as a result, we might have better ovarian stimulation with more mature follicles for IVF.

Does IVF protocol affect egg quality?

Does IVF protocol affect egg quality

IVF protocol usually does not have a major effect on egg quality, however, a bad choice of the protocol can lead to diminished egg quality or further health complications. An unsuccessful IVF outcome can sometimes be related to the wrong type of IVF protocol. Stimulation protocol helps increase fertility in women, especially when they are in advanced ages. Low egg quality can lead to genetic defects in the embryo which results in a higher chance of IVF failure or miscarriage. When the eggs are stimulated, ovaries are supposed to produce more than one cycle per cycle. Then the embryos are created and if there is more than one healthy embryo, they can be frozen for future use. However, in case no healthy embryo is found, there is a need for another IVF cycle. The type of protocol and medication adjustment should be decided based on each patient’s ovarian reserve.

Does long protocol IVF produce more eggs?

Studies have shown that there is little difference in the result of IVF protocols but the short protocol has less risk for OHSS compared to long protocol. In the long IVF protocol, the doctor tries to stimulate the patient’s ovaries by using certain drugs one week before her menstruation cycle starts. These medications suppress two hormones called Follicle Stimulating Hormone (FSH) and luteinizing hormone (LH) which are made in the pituitary gland and cause your ovary to make eggs. By suppressing these two hormones, the ovaries become suppressed and do not make eggs, and the ovarian hormone is called estradiol.

Once the ovarian function has been suppressed, usually after 10-14 days, you will start taking the second set of medication which is named gonadotrophins, and should be administered for 12-14 days. Gonadotrophins stimulate follicles’ growth and prepare them for egg retrieval. During this time, you will be monitored every 3-4 days to evaluate the medication effects on your follicles.

What is the Goal of a good IVF Ovarian Stimulation?

The goal of stimulating ovaries is to get about 8 to 15 eggs at the egg retrieval procedure in order to make sure IVF process works and end to a suitable result. Fertility doctors have to be careful not to overstimulate the ovaries because it leads to Ovarian Hyper-Stimulation Syndrome (OHSS) which can cause discomfort and disease for the patient.
In the recent years, Lupron triggers are used to keep high success rates and significantly decrease the risks of ovarian hyper-stimulation at the same time. On the other hand, stimulation should not be to the low extent so that retrieved eggs be insufficient. Of course there is a possibility of IVF success by the use of very low number of the eggs, but the success rate goes noticeably higher when more eggs are harvested.

How many Follicles is needed to Get Pregnant with IVF?

It is not usually difficult to get enough follicles to use for insemination, however sometimes ovaries do not respond well to the stimulating medications. This issue can be related to the factors like the age of the woman, the way that the ovaries respond to the medications, and the couple’s willingness for continuing the egg retrieval process. The fewer eggs we have, the fewer chances of IVF success can be observed.
The ability of ovaries for stimulation can be predicted relatively well by an ultrasound test. The number of needed follicles depends on the factors like their size, age of the woman, the FSH level, etc. A doctor might do the egg retrieval with only one follicle while the other doctor wants a minimum of 3-4 mature follicles. However, the minimum number that is needed for IVF process can be on average 3 to 5 follicles, so that IVF procedure works well.
