Embarking on the journey of in vitro fertilisation? Get ready for a ride through the complexities of modern fertility treatment. From navigating hormonal changes to scheduling clinical procedures that blend hope with science, IVF is a profound journey filled with challenges and unexpected moments. Let’s explore this path where the pursuit of parenthood meets the realities of medical science.

Understanding In Vitro Fertilisation (IVF)

In vitro fertilisation (IVF) helps couples with infertility achieve pregnancy. IVF involves fertilising an egg with sperm in a lab and growing the embryo for a few days before transferring it to the woman’s uterus, increasing the chances of pregnancy. Originally designed for tubal disease, IVF now treats various infertility causes, including endometriosis and unexplained infertility. Women with primary ovarian insufficiency or age-related egg decline can use donor eggs to achieve pregnancy.

The first successful IVF birth happened in England in July 1978, thanks to Robert Edwards, Ph.D., and Patrick Steptoe, MD. Dr. Edwards later won the Nobel Prize in Medicine in 2010 for this achievement. Since then, in vitro fertilisation has significantly advanced infertility treatment, now accounting for 1.6% of live births in the U.S. and 4.5% in Europe.

An IVF procedure, or “IVF cycle,” has been successful for over four decades, leading to over 10 million births worldwide. A complete IVF cycle typically lasts around 14 to 21 days. Today, there are over 500,000 in vitro fertilisation deliveries annually, making up about 2% of U.S. births in 2018. The chance of having a baby with IVF depends on the patient’s or donor’s age, as younger patients usually have better quality eggs. Multiple cycles may be needed, but sometimes pregnancy doesn’t occur even after several attempts.

If you’re struggling to get pregnant, see your doctor for a medical review and physical exam. They might suggest lifestyle changes and, after a year of trying without success, consider fertility tests and treatments. Your doctor may refer you to a fertility specialist for further tests and possible IVF treatment. Women might undergo hormone tests and ovarian function checks, while men may need to provide a semen sample. If IVF is recommended, you’ll be referred to a specialist unit.

Why People Choose IVF

People choose in vitro fertilisation for many reasons, such as:

  • Infertility or health conditions such as cancer in one partner.

  • Advanced maternal age.

  • Failed attempts with other fertility methods.

  • Same-sex couples or individuals wanting a baby without a partner.

In Vitro Fertilisation can help treat infertility in various situations by providing solutions tailored to specific reproductive challenges. It can be effective for:

  • Blocked or damaged fallopian tubes.

  • Endometriosis.

  • Ovulation disorders like polycystic ovary syndrome (PCOS), premature ovarian failure (POF) or Primary ovarian insufficiency (POI).

  • Uterine fibroids or other uterine issues

  • Unexplained infertility.

  • Genetic disorders.

  • Male infertility factors (low sperm count or poor motility).

  • Fallopian tubes removal.

IVF can also be used when fertility is not an issue, for instance with people using donor eggs. People under this category include people:

  • Without functioning ovaries or after ovary removal.

  • That are postmenopausal.

  • With recurrent pregnancy loss.

  • With failed IVF cycles or poor ovarian response.

The In Vitro Fertilisation Process: Step-by-Step

According to the National Health Service, there are 6 stages in the IVF process each of which are critical for the success of the procedure.

The In Vitro Fertilisation Process: Step-by-Step

  • IVF starts by using medications like birth control pills or oestrogen to suppress the natural menstrual cycle. This prevents ovarian cysts and allows precise timing of treatments, enhancing the chances of successful egg retrieval and fertilisation.
  • Next, ovarian stimulation is initiated through injectable hormones such as the follicle-stimulating hormone (FSH). This encourages the ovaries to produce multiple eggs, increasing the likelihood of retrieving viable eggs.
  • Regular ultrasound scans and blood tests monitor egg development. When the eggs are mature, a trigger shot of human chorionic gonadotropin (hCG) or another agent is administered to prepare them for retrieval.
  • Egg retrieval is performed using a thin needle guided by ultrasound to extract the eggs from the ovaries. It is done under mild sedation to minimise discomfort. The retrieved eggs are then incubated while awaiting fertilisation.
  • Fertilisation is achieved through intracytoplasmic sperm injection (ICSI), where mature eggs are individually injected with sperm. About 70% of mature eggs are typically fertilised successfully. Any extra eggs can be frozen for future use.
  • The final stage is embryo transfer, where embryos are placed into the uterus using a thin catheter. This can involve fresh or thawed frozen embryos. Hormonal medications prepare the uterus for implantation.

  • The final stage is embryo transfer, where embryos are placed into the uterus using a thin catheter. This can involve fresh or thawed frozen embryos. Hormonal medications prepare the uterus for implantation.

After the embryo transfer, you’ll need to wait about two weeks before taking a pregnancy test to determine if the treatment has been successful. During this waiting period, it’s important to follow your healthcare provider’s advice and take care of your physical and emotional well-being.

Factors Affecting IVF Outcomes

IVF success depends on factors such as:

  • Age of the egg donor.

  • Infertility causes.

  • Outcomes of past pregnancies.

  • Sperm quality.

  • How ovaries respond to medication.

Challenges can occur at different stages, such as poor ovarian response leading to cycle cancellation or issues with fertilisation and embryo quality. Difficulty with embryo transfer is rare but possible. The main reason for IVF failure is often poor embryo implantation due to quality issues. 

When assessing IVF outcomes, it’s important to consider both the chance of a successful live birth and the risk of high-order multiple pregnancies (triplets or more). Clinics aim to maximise live birth rates while minimising these risks.

Success Rates of IVF Procedures

Success rates are highest in younger women, with lower rates in those over 42. In the UK in 2019, live birth rates per IVF treatment cycle were highest for women under 35 and decreased with age:

  • 32% for women under 35

  • 25% for women aged 35 to 37

  • 19% for women aged 38 to 39

  • 11% for women aged 40 to 42

  • 5% for women aged 43 to 44

  • 4% for women aged over 44

These statistics highlight the impact of age on IVF success rates and help guide treatment decisions.

Side Effects of In Vitro Fertilisation

After in vitro fertilisation, most women can resume normal activities the day after the procedure, although it’s advised to take it easy. Even so, there are possible side effects that come with the procedure that you need to be aware of ahead of and after the procedure. They include:

  • Passing a small amount of fluid (clear or blood-tinged).

  • Mild cramping.

  • Mild bloating.

  • Constipation.

  • Breast tenderness.

Fertility medications used in IVF can cause:

  • Headaches.

  • Mood swings.

  • Abdominal pain.

  • Hot flashes.

  • Abdominal bloating.

  • In rare cases, ovarian hyperstimulation syndrome (OHSS).

After embryo transfer, common side effects include:

  • Constipation or bloating.

  • Cramping.

  • Breast tenderness.

  • Spotting.

IVF can be emotionally challenging, causing feelings of depression and anxiety for many. It’s important to discuss these feelings with your partner and your healthcare provider for support.

Risks and Complications of In Vitro Fertilisation

While IVF offers hope for many struggling with infertility, it’s important to be aware of the potential risks and complications associated with the procedure. Understanding these risks can help you make informed decisions and prepare for any challenges that may arise during your fertility journey.

  • Multiple births leading to premature labour.

  • Increased miscarriage risk.

  • Ectopic pregnancies.

  • Complications during egg retrieval like bleeding or infection. 

While IVF pregnancies can sometimes be considered high-risk due to factors like advanced maternal age or expecting multiples, many women successfully navigate these challenges with proper medical care. Potential issues such as blood clots, infections, high blood pressure, and gestational diabetes can be effectively managed.

Ensure to attend your check ups with your medical practitioner regularly to notice any possible risks in time and have them treated. With close monitoring and support from healthcare providers, the chances of a healthy pregnancy and baby are greatly enhanced.

Cost and Financial Considerations of IVF

In vitro fertilisation treatments are costly, including expenses for blood tests, imaging, medications, egg retrieval, embryo implantation, lab work, and embryo storage. In the U.S., each IVF cycle costs over $15,000 on average, and multiple cycles may be required. Often, insurance does not cover these treatments, and only some states require coverage.

In England, NHS-funded IVF eligibility is determined by local integrated care boards (ICBs), which may have stricter criteria than NICE guidelines. For those not eligible or opting for private treatment, costs can reach up to £5,000 per cycle.

In Australia, as of February 2024, an IVF cycle costs $11,566, with out-of-pocket expenses for the first cycle at $6,029 and $5,346 for subsequent cycles in the same year.

How to be Emotionally Ready for the IVF Process

Preparing for IVF can be an emotional journey, requiring resilience, patience, and support. It’s essential to understand the potential challenges and equip yourself with strategies to navigate the emotional ups and downs. 

Being emotionally ready for the IVF process involves fostering a positive mindset, seeking support, and practising self-care, amongst other things, to enhance your overall well-being.

How to be Emotionally Ready for the IVF Process

Understand the in vitro fertilisation process and gather information from reliable sources. Knowledge can alleviate anxiety and empower decision-making. Knowing what to expect at each stage of IVF can help you feel more in control and less overwhelmed.

Anticipate decisions such as the number of embryos to transfer and storage options for any remaining embryos. Discuss these choices with your partner and healthcare provider, considering the moral and emotional implications to ensure you are both comfortable with the plan.

Infertility can strain relationships and self-esteem. Prioritise emotional health by communicating openly with your partner, seeking counselling if needed, and setting boundaries for discussing IVF. Taking care of your emotional well-being helps maintain a supportive environment throughout the treatment.

Choose wisely whom to confide in about your IVF journey to manage pressure. Consider joining support groups or online communities for additional understanding and encouragement. A strong support system can provide comfort and practical advice from others who have gone through similar experiences.

Recognise what triggers stress during treatment and develop coping mechanisms. Exercise, humour, and stress management techniques can help maintain emotional balance. Having a plan for handling stress can make the process feel more manageable.

Focus on what you can influence during the IVF cycle, like following medical advice and maintaining a healthy lifestyle. Minimise major life changes and stressors to create a stable environment. This includes managing your workload, setting boundaries, and practising mindfulness to feel empowered during the process.

Plan for emotional highs and lows during the waiting period after embryo transfer. Prepare how to occupy your time and decide how and when to share results with loved ones. Knowing how you’ll handle both positive and negative outcomes can help you feel more prepared for whatever comes.

Alternatives to In Vitro Fertilisation

Alternative treatments to IVF offer less invasive options for couples experiencing infertility. These include lifestyle changes, medications to stimulate ovulation, intrauterine insemination (IUI), and targeted therapies for specific causes like endometriosis or male infertility. These approaches aim to enhance natural fertility and increase the likelihood of conception, tailored to individual health needs and preferences.

Intrauterine Insemination (IUI)

IUI places sperm directly into the uterus, bypassing the vagina and cervix, increasing the number of sperm that reach the uterus. It’s helpful for men with low sperm count and other cases. The process involves inserting sperm into the womb using a thin tube, with the best sperm selected after washing.

Egg and Sperm Donation

If you or your partner have infertility issues, you can use donor eggs or sperm to conceive. Donor eggs are usually used in IVF. Donors registered in England after April 1, 2005, must disclose their identity, allowing children conceived from donations to learn the donor’s identity at age 18.

Fertility Medicines

Common fertility medications include Clomiphene, Tamoxifen, and Gonadotropins.Traditionally, clomiphene citrate has been the go-to medication for inducing ovulation in PCOS patients, boasting an 80% success rate. However, recent studies suggest that letrozole may be more effective, leading to higher live birth rates. 

For unexplained infertility, clomiphene citrate combined with intrauterine insemination remains the preferred treatment. Possible side effects include nausea, vomiting, headaches, and hot flashes. Ovarian stimulation medications are not recommended for women with unexplained infertility. Only use medications prescribed by your fertility specialist or medical practitioner.

Assisted Hatching (AH)

Assisted hatching improves success rates for certain groups. It involves creating a hole in the embryo’s outer layer (zona pellucida) to help it escape and implant in the uterus. AH is offered to older patients, those with repeated implantation failures, and those with thicker zona pellucida. The zona pellucida is a protective outer layer around the egg cell that plays key roles in fertilisation and early development.

Adoption

Adopting a child is a life-changing decision that brings immense joy and fulfilment. Each family’s experience is unique, but the rewards of providing a loving home and becoming a parent are immeasurable. The adoption process, though challenging, is worth it for the strong family bonds and cherished memories it creates.

 Whether it’s welcoming your first child or expanding your family, adoption promises a bright and joyful future.
