How IVF Works: A Step-by-Step Guide to In Vitro Fertilization

In vitro fertilization, or IVF for short, is one of the most popular forms of infertility treatment, and rightfully so. This treatment has a rather high success rate, is relatively less invasive, and is fairly affordable, given its success rate. But there is a small catch- not many people know about its process and how IVF works in general. Well, the overall gist of the process is rather simple - eggs and sperm are taken out and fertilized in a laboratory before being transformed into embryos and transferred back into the uterus. But this is just the general gist of the whole process; what about the specifics? Well, this is exactly what we will be discussing here today. 

In this blog, we shall provide you with an overall gist of what an IVF is, why it is performed, and how you prepare for this process. Along with this, we shall also provide you with brief information regarding what to expect, some common side effects and its success rate. Now, since we have a lot to discuss, let's get started right away. 

What Is In Vitro Fertilization (IVF)?

What Is In Vitro Fertilization (IVF)

Before we discuss anything else, let’s first talk about what this process is first. So, what is IVF? In simplest terms, IVF is a form of Assisted Reproductive Technology or ART for short, which aids in circumventing the issue of infertility. The process of IVF typically revolves around retrieving eggs from the ovary and manually combining them for fertilization. Once the eggs are fertilized, they are then placed back into the uterus for conception. 

Since fertilization occurs outside the uterus, the good news here is that you can use this process with the sperm or your partner or donor sperm. On top of this, you can also use an additional treatment, such as preimplantation genetic testing (PGT) alongside IVF, to further boost its already high success rates.

Why Is IVF Performed? 

After the what, let's now discuss the why of IVF. Why is IVF performed? The simplest answer to this question is “to cure infertility.” But if you want to go a bit deeper into why this process is performed, you will need to dig a bit deeper and know a few more reasons why people use this treatment. Some of the key reasons include: 

1. Blocked or Damaged Fallopian Tubes

One of the key reasons why people conduct IVF is when they have a blocked fallopian tube. The fallopian tubes are essential for moving eggs from the ovaries to the uterus, and if they are blocked or damaged, they can prevent eggs from reaching the uterus. The good thing about IVF is that it directly bypasses the fallopian tubes as the eggs are fertilized in the lab and then placed into the uterus.

2. Ovulation Problems

Another key reason why you might want to consider IVF is if you have ovulation issues such as irregular or nonexistent ovulation. The IVF process includes stimulating the ovary to release eggs, which negates this issue altogether. 

3. Endometriosis 

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus, often affecting the ovaries, fallopian tubes, or uterus itself. This can interfere with egg fertilization and implantation. IVF can improve the chances of pregnancy by bypassing these complications.

4. Uterine Fibroids

Yet another one of the key reasons why you might want to consider IVF is if you have uterine fibroids. These fibroids are essentially non-cancerous growths in the uterus. IVF bypasses this issue by essentially placing the eggs in the areas not affected by the fibroids. 

5. Sperm Problems 

IVF doesn’t just solve issues concerning female infertility issues. You can also use this treatment if your partner has issues with his sperm. During this process, the reproductive experts select the best sperms before using them to fertilize the eggs, essentially eliminating the issues caused by sperms with low motility and abnormalities. 

6. Unexplained Infertility

Besides dealing with the known causes of infertility, IVF is also great at dealing with the unknown ones. Since the entire process is carefully monitored, this process essentially eliminates the contamination of the process from unknown factors and, as a result, can provide you with a high success rate even if the cause of your or your partner's infertility is undetermined. 

Besides the core reason we mentioned here, IVF is also the first option if you are above 40, have severe fallopian tube damage, or have low sperm counts. Regardless, this list only covers some of the key reasons why you may want to choose this form of ART.  Still, we hope you understood the general gist of it all and know that IVF is perfectly suitable as the first choice in most general circumstances.

How does IVF work? Step-by-Step Process

How does IVF work Step-by-Step Process

Now, we move on to the core topic of this discussion. You can phrase this question in many forms, such as how IVF works step by step, how IVF treatment works, how IVF process works, or even how IVF pregnancy works. Regardless of how you phrase the question, the answer remains the same. So, what exactly is the process? The specific process can vary to some extent depending on your medical and reproductive health. However, the core processes are as follows:

1. Birth Control Pills Or Estrogen 

Although taking birth control pills or estrogen during an infertility treatment may sound a bit counterintuitive, believe us, it is an essential part of the IVF process. What taking these medications does is stop the development of the ovarian cyst so that the doctors can control the timing of the menstrual cycle. This essentially gives the experts the power to control when the menstrual cycle begins and maximize the number of mature eggs during the retrieval process. 

2. Ovarian Stimulation

This is the second step in how IVF works, and in this step, the reproductive experts essentially provide you with medications that stimulate your ovaries to produce eggs. Although you only have one egg each month, by stimulating ovaries, the experts ensure that multiple eggs are produced simultaneously. That said, the specifics of the stimulating medications depend on your individual factors. Some of the key factors looked at when providing you with stimulating hormones include:

  • Medical history
  • Age
  • Anti Mullerian Hormone (AMH) level

Response to ovarian stimulation process during previous IVF cycle (if you have had any)
Once you are provided with the stimulating hormones, the experts then carefully monitor the response to the stimulation using ultrasound and blood hormone levels every few days. While the eggs themselves are too small to be visible with ultrasound, they can monitor the ovarian follicles, which are essentially small sacs that contain the eggs. 
When the experts determine that your eggs are ready for final maturation based on these tests, they then provide you with a trigger shot in preparation for egg retrieval. This shot is given exactly 36 hours before the egg retrieval time. 

3. Egg Retrieval

Following the stimulation phase is the egg retrieval stage. During this phase, you need to visit the fertility clinic. Once you reach the clinic, the experts use an ultrasound to guide a thin needle into your ovaries through your vaginal opening. They then use a suction device to pull your eggs from each follicle. The entire process is quick and only takes about 20 to 30 minutes. And the best part about this step, besides the quick time, is that you shall not feel a thing since you are mildly sedated.

Back to the process: once the eggs are retrieved, they are then placed in a dish that contains a special solution and then inserted in an incubator before they are ready to be fertilized. 

4. Fertilization 

After the eggs are retrieved, the next phase of how IVF works is fertilization. This is where fertilization takes place. This step takes place on the same afternoon of the egg retrieval process, and in this phase, the experts use intracytoplasmic sperm injection or ICSI to fertilize the eggs on each of the mature eggs. Now, note that this process cannot be done on immature eggs. Regardless, once all the mature eggs are fertilized, they are then left for incubation until they reach the blastocyst stage. 

On average, the success rate of fertilization is roughly 70% to 80% at Hardik IVF and Fertility Center. The good news here is that if the experts retrieve a large number of eggs and you do not want them to be fertilized, you have the option to freeze them for later use or even donate them if you want to. 

5. Embryo Development 

Embryo development is essentially a waiting period, as once the eggs are fertilized, they are kept in an incubator for the next six days. It is during this period that the eggs reach the blastocyst stage. However, depending on the quality of the eggs, not all of them reach this stage and fail to progress. The ones that do not reach the blastocyst stage are discarded, while the ones that do are prepared for transfer or frozen on the fifth or sixth day. 

6. Embryo Transfer 

This is the final step in how IVF works, and in this phase, the fertilized eggs are transferred into the uterus. But before this process begins, you do need to take in hormones through oral or injection means to prepare your uterus for the acceptance of the embryo. Once your body is deemed ready, at around 14 to 21 days of medication followed by six days of injections, you shall be scheduled for embryo transfer. 

Now, do note that you shall not be provided with any forms of anesthesia as this process is mildly discomforting at worst. In this process, a thin catheter is inserted through a cervix into the uterus. Then, a syringe attached to the other end injects the embryos into the uterus. The entire process only takes around 10 minutes.

How do you Prepare for IVF?

How do you Prepare for IVF

Now that we have covered the core topic of our blog, let's discuss some additional but still relevant information before we reach the end and conclude our topic. The next topic on our agenda, following how IVF works, is how to prepare for the IVF process. Well, there are a few things you can do, among them some of which include:

  • Meet with healthcare professionals who provide IVF and discuss the process.
  • Take the regular uterine examination 
  • Take a semen analysis
  • Check for STDs and other infections

  • Constipation
  • Mild bloating 
  • Cramping
  • Spotting
  • Breast tenderness 

That said, you can return to regular activities right after the egg retrieval process and the embryo transfer process. However, you should not drive for 24 hours after anesthesia should be provided to you. Furthermore, you should also note that you are not to do any form of stressful activities, be it physical or mental, during the whole process. 

Common Side Effects of IVF

Among many things you can expect after the IVF process, you might also want to prepare for the side effects. While the side effects are somewhat rare, they are still not rare enough for you to completely ignore them. Some of the common side effects you might face after the IVF process include: 

  • Nausea 
  • Vomiting 
  • Headaches
  • Hot flashes 
  • Enlargement of ovaries
  • Abdominal pain
  • Bruising of IVF injections 

Besides this, some common side effects after the IVF process include: 

  • Constipation
  • Bloating 
  • Breast tenderness 
  • Cramping
  • Spotting 

Now, note that while you should be wary of these side effects, you should not be anxious about them, as being overly anxious can cause more harm than good. 

Risks of IVF

Alongside the side effects of IVF, you should also be aware of some of its risks. Now, you should also note that the risk of IVF is minuscule, similar to the side effects. Regardless, there are some risks of IVF that you can keep in mind. Some of the relatively common risks of IVF include: 

  • Premature Delivery: Slightly increased risk of your baby being born underweight, and this can be considered as an IVF baby disadvantage
  • Miscarriage: Same risk of miscarriage as normal pregnancy. 
  • Ectopic Pregnancy: This pregnancy occurs when the fertilized egg implants outside the uterus, but the risk is lower than that of normal pregnancy. 
  • Complications During Egg Retrieval: Rare chance of complications such as bleeding, infection, damage to the gallbladder, bowel or reproductive organs
  • OHSS: Another rare condition that can cause nausea, abdominal pain, vomiting, and diarrhea. 

This is just a brief compilation of the risks of IVF treatment, and the ones we mentioned here are just some of the relatively common ones. Besides the ones we mentioned here, there are rare ones as well, but they are rare enough not to worry at all.
