What is In Vitro Fertilization?

At a Glance: IVF, or in vitro fertilization, is a complicated process that can lead to pregnancy. It is often used to treat infertility, which is when a couple has been trying to get pregnant for at least a year without success. IVF can also help prevent genetic disorders from being passed down to future generations. First, mature eggs are taken from the ovaries. Then, sperm is used to fertilize these eggs in a lab. Once fertilized, the embryos are implanted into the uterus. This is where they develop into babies.

Whether you are new to fertility treatments or already undergoing IVF, this guide provides practical advice, clarity, and reassurance. 

So get ready to embark on a journey that's as life-changing as it is awe-inspiring: the step-by-step guide to the IVF process awaits.

Understanding the Term IVF Process

In vitro fertilization (IVF) is a medical procedure that can help people who are struggling to conceive a child due to infertility. It involves a series of complex steps and is a form of Assisted Reproductive Technology (ART). 

IVF may be a suitable option for individuals or couples who are facing fertility issues due to various reasons, including ovulation disorders, blocked fallopian tubes, endometriosis, uterine fibroids, male infertility, or a genetic condition in one partner. 

It can also be a viable option for same-sex couples who want to have a child or for individuals who wish to preserve their fertility for future childbearing.

Reasons to opt for IVF Process

IVF is recommended if you or your partner suffer from any of the following conditions:

  • Blocked or damaged fallopian tubes
  • Endometriosis
  • Low sperm count or other sperm impairments
  • Polycystic ovary syndrome (PCOS) or other ovarian conditions
  • Uterine fibroids
  • Problems with your uterus
  • Risk of passing on a genetic disease or disorder
  • Unexplained infertility
  • Using an egg donor or a gestational surrogate

Preparation of IVF Process

To prepare for IVF, you will need to go through several steps, which include:

  • Meeting with healthcare providers to discuss details of the IVF process
  • Undergoing a uterine exam, an up-to-date Pap test, and a mammogram (if over 40)
  • Having a semen analysis
  • Being screened for sexually transmitted infections (STIs) and other infectious diseases
  • Taking ovarian reserve testing, blood, and urine tests
  • Receiving instructions on how to administer fertility medications
  • Undergoing genetic carrier screening
  • Signing consent forms
  • Having a uterine cavity evaluation

Steps of IVF Process

IVF treatment is a multi-step process, and each step is crucial in getting positive results.

Step 1 (Birth Control Pills)

During this step birth control pills may be given to females before IVF treatment.

This may seem counterintuitive, but taking birth control pills before the IVF cycle may increase the chances of success.

It may also reduce the risk of ovarian hyperstimulation syndrome and ovarian cysts.

Step 2 (Ovarian Stimulation)

At this stage, doctors will prescribe medications to stimulate the ovaries to produce and release multiple eggs.

The more eggs produced and released, the better the chances of fertilization.

Professionals will monitor the patient's progress with blood tests and ultrasounds to check the maturing of the eggs.

Step 3 (Egg Retrieval)

Once the maturing process is completed, doctors will retrieve the eggs using a needle and ultrasound.

This procedure takes around 20-30 minutes and is done under anaesthesia.

Although this step may cause mild discomfort or cramps, it is not severely painful. 

Women may experience some vaginal bleeding or spotting after the procedure, but this is normal.

If there is excessive pain or bleeding, it is important to contact a specialist.

Step 4 (Fertilization)

The collected eggs are left for fertilization with the donor's or partner's sperm in a special laboratory tray.

Specialists will monitor the eggs for a few days to ensure that they are developing properly.

In some cases, they may use intracytoplasmic sperm injection (ICSI), where the sperm is directly injected into the egg.

Step 5 (Embryo Transfer)

After successful fertilization and embryo formation, specialists will use a catheter to place one or more embryos in the uterus. The transfer is done without anaesthesia.

The number of eggs transferred largely depends on several factors, including fertility history, embryo quality, and age.

Step 6 (Pregnancy Test)

Around two weeks after the embryo transfer, the female will be advised to take a pregnancy test to check for a positive result.

In case of successful conception, routine check-ups and monitoring are done.

How Long is the IVF Process from Start to Finish?

An IVF cycle usually lasts 6-8 weeks. It involves an initial consultation, ovarian stimulation lasting 8-14 days, egg retrieval, fertilization, embryo transfer, and a pregnancy test.

The embryo transfer and pregnancy test are commonly done 5 days post-fertilization.

Success Rate of IVF

The success rate depends on a number of factors including reproductive history, maternal age, the cause of infertility, and lifestyle factors.

It is also important to understand that pregnancy rates are not the same as live birth rates.

  • 41-43% for women under age 35
  • 33-36% for women ages 35 to 37
  • 23-27% for women ages 38 to 40
  • 13-18% for women ages over 40

Side Effects of the IVF Process

IVF has some risks and possible side effects, which include:

  • bloating
  • cramping
  • breast tenderness
  • mood swings
  • headaches
  • bruising from shots
  • allergic reaction to medicines
  • bleeding
  • infection

Psychological Impact of the IVF Process

Anticipation and uncertainty: The uncertainty of whether the treatment will be successful can cause significant stress and anxiety. While each treatment cycle brings hope, it also has the potential for disappointment.

Outcome anxiety: The fear of a negative outcome, which includes the fear of multiple failed attempts, can weigh heavily on the patient's emotions.

Financial stress: The high cost of treatments like IVF can lead to financial anxiety, impacting overall emotional well-being.

Impact of Hormonal Treatments

Mood swings: Fertility treatments often involve hormone injections, which can lead to significant mood swings and volatile emotions.

Physical and emotional fatigue: The physical demands of the treatment process, combined with hormonal side effects, can lead to exhaustion and emotional fatigue, especially when treatment is long-term.

Relationship Dynamics

Partner relationships: The stress of fertility treatments can strain relationships. Couples may experience increased tension, differing coping mechanisms, and difficulties in communication.

Sexual intimacy: The medicalization of conception can impact sexual intimacy and spontaneity, leading to a sense of loss or frustration in the relationship.

Social relationships: Interactions with friends and family who may not understand the fertility journey can become challenging, leading to feelings of isolation or being misunderstood.

Depression and Grief

Loss and grief: Each failed cycle or pregnancy loss can cause profound grief and a sense of loss, which can accumulate over time, leading to bitterness, anger and frustration.

Depression: The cumulative emotional toll of ongoing treatments, along with the stress and potential disappointments, can lead to depression.

Coping with Multiple Attempts

Resilience and persistence: The need to repeatedly go through the physically and emotionally demanding process of fertility treatments can test an individual’s resilience and emotional endurance.

Desensitization and numbness: Over time, the repetitive nature of treatments can lead to emotional desensitization or numbness as a coping mechanism, which the therapist must address to help the couple cope up with the treatment.

Risks Associated with the IVF Process

IVF can increase the risk of certain health problems, both in the short and long term.

Some of these risks include:

Stress: IVF can be emotionally, physically, and financially taxing. It is important to seek support from counselors, family, and friends to help you and your partner through the ups and downs of infertility treatment.

Ovarian hyperstimulation syndrome(OHSS): This is a condition in which the ovaries become swollen and painful. It can be caused by receiving shots of fertility medicines, such as human chorionic gonadotropin (HCG), to trigger ovulation. Symptoms can last up to a week, including mild belly pain, bloating, upset stomach, vomiting, and diarrhea.

Complications during egg retrieval: Bleeding, infection and damage to your bladder, bowel or reproductive organs during the egg retrieval process.

Miscarriage: Miscarriage is a possibility for those who conceive using IVF with fresh embryos. The rate of miscarriage is similar to that of people who conceive naturally.

Ectopic pregnancy: Ectopic Pregnancy is a condition where a fertilized egg attaches to tissue outside the uterus, most commonly in a fallopian tube. As a result, the embryo can't survive outside the uterus, and there's no way to continue the pregnancy. A small percentage of people who use IVF might experience an ectopic pregnancy.

Multiple pregnancies: IVF raises the risk of having multiple pregnancies. Becoming pregnant with multiple babies carries higher risks of pregnancy-related high blood pressure and diabetes, early labour and delivery, low birth weight, and birth defects than pregnancy with a single baby.

Birth defects: The age of the mother is the main risk factor for birth defects, no matter how the child is conceived. However, assisted reproductive technologies such as IVF are linked with a slightly higher risk of a baby being born with heart issues, digestive problems, or other conditions.

Conclusion

Navigating the IVF process can be emotionally and physically challenging, but with adequate knowledge and support, individuals and couples can approach it confidently. 

From initial consultations to embryo transfer and beyond, each step plays a crucial role in realizing the dream of parenthood.

Remember, every IVF experience is unique, so prioritize self-care and open communication with healthcare providers.

By staying informed, resilient, and hopeful, many get closer to welcoming a new addition to their family.

If you're considering IVF, it's crucial to consult a specialist to get personalized advice and ensure you're prepared for the journey ahead.

FAQs

How to calculate pregnancy weeks after IVF?

To determine the number of weeks a pregnancy has progressed after IVF, you should count the number of weeks from the embryo transfer date to the current date.

When to take a pregnancy test after IVF?

A pregnancy test should only be taken two weeks after the embryo transfer has taken place. That's because it takes about seven to ten days for the fertilized egg to reach the uterus and the mother's body to produce the hormone hCG, which is the hormone that pregnancy tests detect. This means that two weeks after your embryo transfer, your blood hCG levels will be high enough for a pregnancy test to tell if you are pregnant.

Is it painful to have IVF?

Each patient reacts differently to IVF, so it might be painful for one person and might not be painful for another. Some IVF procedures, like injections and egg retrieval, can cause some pain, but it should never be unbearable.

What causes failed IVF?

While IVF boasts high success rates, it can still fail, often due to chromosomal abnormalities or the influence of age. In some cases, the reasons for failure remain unexplained.
