Brief overview of IVF:
In vitro fertilization (IVF) is a widely used assisted reproductive technology (ART) that helps individuals and couples conceive when natural conception is challenging.
The process involves fertilizing an egg with sperm outside the body in a laboratory and then transferring the resulting embryo to the uterus to achieve pregnancy.
what is IVF ??
In vitro fertilization (IVF) is an assisted reproductive technology (ART) in which eggs and sperm are fertilized outside the body in a laboratory. And the embryos formed are then transferred to the uterus to establish a pregnancy. IVF is commonly used to help individuals and couples facing infertility or genetic problems.
The term “in vitro” means “in glass,” referring to the laboratory dish where fertilization occurs. Unlike natural conception, where fertilization occurs inside the fallopian tubes, IVF allows medical professionals to carefully control the fertilization process and select healthy embryos for implantation.
History of IVF:
The Early Years of IVF:
The concept of IVF was first discovered in the early 20th century, but significant breakthroughs occurred in the mid-1900s. Scientists worked on understanding the fertilization of eggs outside the human body, leading to the first successful IVF pregnancy.
1950s-1960s: Early experiments on fertilisation outside the womb were carried out on animals.
1973: The first human IVF pregnancy occurs in Australia, but it ended up in a miscarriage.
1978: The world’s first IVF baby, Louise Brown, was born in Britain, revolutionising the medical world . The feat was achieved by British scientists Dr Robert Edwards and Dr Patrick Steptoe, who developed the IVF technique. It was considerd as a breakthrough in medical history.
IVF Process: Step-by-Step Guide
The IVF process involves several steps to ensure the best chances of a successful pregnancy. Each step is carefully managed by fertility specialists to optimize embryo development and implantation. Below is a detailed description of the IVF journey.
Step 1: Initial Consultation and Fertility Testing:
1.1 Consultation with a Fertility expert:
The first step involves meeting with a fertility specialist to discuss the medical history, previous pregnancies, lifestyle factors, and possible causes of infertility.
Both partners (if applicable) are evaluated to determine the most effective treatment plan.
1.2 Fertility Testing for Women:
Hormone tests (FSH, LH, AMH, and estrogen levels) are done to assess ovarian reserve and reproductive health.
Ultrasound to check ovarian follicles and uterine lining.
Hysterosalpingogram (HSG) or Sonohysterography to check the fallopian tubes and uterus.
1.3 Fertility Testing for Men:
Semen analysis to check sperm count, motility and morphology.
Additional tests are done if sperm abnormalities are found.
Step 2: Ovarian Stimulation and Egg Retrieval:
2.1 Ovarian Stimulation
The woman takes hormonal medications (gonadotropins) for 8-14 days to stimulate the production of several eggs.
Regular ultrasounds and blood tests monitor follicle development and hormone levels.
2.2 Trigger Shot and Egg Maturation
When the follicles reach the right size, a trigger shot (HCG or Lupron) is given to mature the eggs.
2.3 Egg Retrieval (Egg Retrieval)
36 hours after the trigger shot, eggs are extracted using a thin needle under ultrasound guidance.
The procedure is performed under mild sedation or anesthesia and usually takes 20-30 minutes.
The collected eggs are sent to the laboratory for fertilization.
Step 3: Sperm collection and fertilization:
3.1 Sperm collection:
The male partner provides a sperm sample on the day of egg retrieval.
If necessary, surgical sperm retrieval (TESA, PESA) is used for men with low sperm counts.
Donor sperm can also be used if necessary.
3.2 Fertilization methods:
Conventional IVF: Sperm and egg are mixed in a laboratory dish, making natural fertilization possible.
Intracytoplasmic sperm injection (ICSI): A single sperm is injected directly into the egg, which is helpful in cases of male infertility.
Step 4: Embryo development and selection
4.1 Embryo culture:
Fertilized eggs develop into embryos in 3-5 days in an incubator.
The embryologist monitors cell division and growth.
4.2 Embryo grading and selection:
High-quality embryos are selected based on their development.
Some couples opt for preimplantation genetic testing (PGT) to check for genetic abnormalities.
4.3 Freezing the embryos (optional):
Extra embryos can be frozen (cryopreservation) for future use.
Step 5: Embryo transfer and transplant
5.1 Preparing the uterus for transfer:
The woman takes progesterone supplements to thicken the uterine lining for transplantation.
5.2 Embryo transfer procedure:
A selected embryo is transferred into the uterus using a thin catheter.
The procedure is painless, does not require anesthesia and takes only a few minutes.
5.3 Post-transfer care:
The woman is advised to rest and follow a healthy lifestyle.
Medications such as progesterone are continued to support implantation.
Step 6: Pregnancy test and follow-up
6.1 Pregnancy test
10-14 days after embryo transfer, a blood test (beta HCG) confirms pregnancy.
6.2 Follow-up scan
If positive, an ultrasound scan tracks the growth of the embryo.
If unsuccessful, the doctor assesses the causes and discusses future options, including frozen embryo transfer (FET) or another cycle.
IVF Success Rates
The success of in vitro fertilization (IVF) varies depending on many factors, including age, underlying health conditions, and lifestyle choices. Understanding these factors can help individuals and couples set realistic expectations and optimize their chances of a successful pregnancy.
Factors affecting IVF:
1.Age:
women under the age of 35 have the highest success rates because they have better egg quality and ovarian reserve.
Women aged 35-40 see a gradual decline in success rates.
Women over the age of 40 often require donor eggs due to decreased egg quality and quantity.
Age group IVF success rate per cycle (%)
Under 35 40- 50%
35-37 30- 40%
38-40 20- 30%
41-42 10- 20%
Over 42 Less than 10%
2.Health conditions:
Polycystic ovary syndrome (PCOS): Can cause irregular ovulation, but can be treated with medication and lifestyle changes.
Endometriosis: Can affect egg quality and implantation, but can be managed with surgical intervention before IVF.
Fibroids or uterine abnormalities: Can interfere with implantation and may require surgical removal.
Male factor infertility: Low sperm count or poor sperm motility can be treated with intracytoplasmic sperm injection (ICSI).
3.Lifestyle factors:
Smoking and alcohol: Reduces egg and sperm quality, affecting IVF outcomes.
Obesity or being underweight: Can disrupt hormone levels and implantation rates.
Diet and nutrition: A balanced diet rich in antioxidants, folic acid and omega-3 boosts fertility.
Stress and mental health: Excessive stress can negatively impact hormonal balance and implantation.
Average IVF success rate globally
IVF success rates vary across countries depending on medical advancements, technology and patient demographics.
Country/Region Average success rate (%):
USA 35-45%
UK 30-40%
Europe 35-45%
Australia 35-50%
India 25-40%
Developed countries generally have higher success rates due to advanced medical technology, embryo screening (PGT) and better patient care.
Success rates may be low in developing countries due to limited access to fertility specialists, advanced laboratories and expensive treatments.
Ways to Improve IVF Success Rates:
- Medical Strategies
Preimplantation Genetic Testing (PGT): Helps select healthy embryos, reducing the risk of miscarriage.
Blastocyst Transfer (Day 5 Embryos): Improves implantation rates compared to early-stage embryo transfer.
Frozen Embryo Transfer (FET): May be more successful than fresh transfer as the uterus gets more time to recover.
ICSI (Intracytoplasmic Sperm Injection): Helps in cases of severe male infertility.
Endometrial Receptivity Testing (ERA): Determines the best time for embryo transfer.
2. Lifestyle Changes:
Maintain a healthy BMI (18.5-24.9): Improves ovulation and implantation rates.
Eat a fertility-boosting diet: rich in protein, leafy greens, whole grains, and healthy fats.
Reduce stress: Yoga, meditation, and counseling can help manage emotional stress.
Limit caffeine and alcohol: Excessive consumption reduces fertility.
3.Choosing the right fertility clinic:
Research the clinic’s success rates and reviews.
Select experienced fertility specialists.
Investigate advanced IVF techniques like embryo freezing and genetic testing.
