If you are considering IVF, understanding what happens at each stage can make the process feel less uncertain. The IVF treatment process generally involves fertility evaluation, ovarian stimulation, monitoring, egg retrieval, fertilization in a laboratory, embryo development, embryo transfer and a pregnancy test. The exact medicines, timing and number of appointments vary according to your diagnosis and treatment plan.
At Arka Anugraha Hospital in Bangalore, IVF care is planned according to the individual patient rather than following one identical protocol for everyone. You can learn more about integrative fertility care at Arka Health and the broader approach to personalized fertility care.
Treatment decisions should always be made after an in-person consultation with a qualified fertility specialist who can assess your medical history, examination findings and test results.
Quick Answer: What Is the IVF Treatment Process?
The IVF treatment process involves using medicines to stimulate the ovaries to develop multiple eggs, monitoring their growth, retrieving mature eggs, fertilizing them with sperm in a laboratory, allowing embryos to develop and transferring a suitable embryo into the uterus. A pregnancy test is performed after the transfer. Mayo Clinic describes a typical IVF cycle as taking about 2 to 3 weeks, although the overall journey can take longer when preparation or frozen embryo transfer is performed separately.

What Is IVF?
In vitro fertilization, or IVF, is an assisted reproductive technology in which mature eggs are collected from the ovaries and fertilized with sperm in a laboratory. The resulting embryos can then be transferred into the uterus, where implantation may lead to pregnancy.
In vitro fertilization, or IVF, is an assisted reproductive technology in which mature eggs are collected and fertilized with sperm in a laboratory before an embryo is transferred into the uterus. You can also review Mayo Clinic’s IVF guide for an overview of the treatment and its major stages.
IVF may use a patient’s own eggs and sperm, or donor eggs, sperm or embryos in situations where these are medically appropriate.
IVF is not automatically the first fertility treatment for every person. The appropriate approach depends on factors such as age, the cause of infertility, ovarian reserve, sperm factors, previous fertility treatment and other medical considerations.
What Happens Before the IVF Treatment Process?
Before starting an IVF cycle, the fertility team usually evaluates both partners and reviews previous investigations and treatments.
The purpose is to understand the likely cause of infertility, assess reproductive health and determine whether IVF is appropriate.
Fertility evaluation may include:
- Medical and reproductive history
- Ovarian reserve assessment
- Hormonal blood tests where indicated
- Pelvic ultrasound
- Assessment of the uterus and uterine lining
- Semen analysis
- Screening for certain infections where appropriate
- Review of previous fertility treatments
Mayo Clinic notes that ovarian reserve testing, semen analysis and assessment of the uterus may be part of the preparation for IVF.
If you have a condition such as PCOS, endometriosis, diminished ovarian reserve or another fertility-related problem, the treatment plan may be adjusted accordingly.
If you are specifically exploring fertility issues associated with PCOS, you can also read our guide to PCOS and fertility.
How Long Does an IVF Cycle Take?
A typical IVF cycle takes about 2 to 3 weeks once preparations are complete, according to Mayo Clinic. However, the total timeline can be longer depending on the treatment protocol, whether embryo transfer is performed in the same cycle, and whether embryos are frozen for transfer later.
The ovarian stimulation portion commonly lasts around 1 to 2 weeks. NICHD notes that ovarian stimulation medicines may be given for approximately 8 to 14 days, with monitoring using ultrasound and blood tests.
Your fertility specialist will give you a schedule based on how your ovaries respond to medication.
IVF Treatment Process, Step by Step
Step 1: Ovarian Stimulation
Ovarian stimulation uses fertility medicines to encourage the ovaries to develop multiple follicles, which are fluid-filled structures that contain developing eggs.
Normally, the ovaries develop and release one dominant egg during a menstrual cycle. During IVF, medicines are used to stimulate the development of multiple eggs because not every retrieved egg will fertilize or develop into an embryo.
Mayo Clinic explains that injectable hormones such as follicle-stimulating hormone may be used during ovarian stimulation. The exact medicines and doses depend on the patient’s circumstances.
You may need injections for approximately 8 to 14 days, with the duration adjusted according to your response.
What happens during stimulation?
Your fertility team may monitor:
- Follicle growth using ultrasound
- Hormone levels through blood tests
- Your response to the medicines
- The timing of egg maturation
The treatment may be adjusted if your response is slower or stronger than expected.
Step 2: Monitoring and the Trigger Injection
Monitoring helps the fertility team determine when the developing follicles are ready for egg retrieval. A trigger medicine is then used to help the eggs complete their final maturation before retrieval.
Ultrasound examinations allow the fertility team to monitor follicle development. Blood tests may also be used to assess hormone levels.
When the follicles and hormone levels indicate that the eggs are appropriately developed, a trigger injection is given.
The timing of the trigger is important because egg retrieval is scheduled at a specific interval afterward.
NICHD states that egg retrieval is generally performed around 34 to 36 hours after the hCG trigger injection.
Step 3: Egg Retrieval
Egg retrieval is a procedure used to collect mature eggs from the ovarian follicles. It is usually performed using ultrasound guidance and a thin needle passed through the vagina to reach the follicles.
Mayo Clinic describes egg retrieval as a procedure performed after the final maturation medicine, generally around 34 to 36 hours after the final injection.
During the procedure:
- Medication is given to help with comfort and pain.
- An ultrasound probe is used to visualize the ovaries.
- A thin needle is guided through the vaginal wall into the follicles.
- Fluid containing the eggs is aspirated.
- The embryology laboratory identifies and evaluates the retrieved eggs.
NICHD reports that egg retrieval is generally an outpatient procedure and may take around 30 minutes, although the exact duration varies.
What might you feel afterward?
Mild cramping, pelvic discomfort, bloating or a feeling of fullness can occur after egg retrieval.
Your fertility team will tell you which symptoms are expected and which require medical attention.
Step 4: Sperm Collection and Fertilization
After egg retrieval, the eggs are taken to the embryology laboratory.
A sperm sample may be collected on the day of egg retrieval or prepared beforehand depending on the treatment plan.
There are two commonly discussed methods of fertilization.
Conventional IVF
In conventional IVF, prepared sperm are placed with mature eggs in a laboratory dish under controlled conditions. Fertilization is then assessed by the embryology team.
ICSI
Intracytoplasmic sperm injection, or ICSI, involves injecting a single sperm directly into a mature egg.
ICSI may be considered when sperm count or movement is significantly affected, or when previous fertilization attempts have not resulted in successful fertilization. Mayo Clinic describes ICSI as an option particularly when semen quality or sperm number is a concern or when previous IVF fertilization has failed.
ICSI is not automatically required for every IVF cycle. Your fertility and embryology team can determine whether it is appropriate based on your individual circumstances.
If you want to understand ICSI, PGT-A and other optional procedures in more detail, you can read our guide to IVF add-ons such as ICSI and PGT-A.
Step 5: Embryo Development and Culture
After fertilization, embryos are kept in the laboratory under carefully controlled conditions while the embryology team monitors their development.
The early embryo undergoes several stages of development.
By approximately day 5 or 6 after fertilization, an embryo that has continued developing may reach the blastocyst stage.
Mayo Clinic describes a blastocyst as a rapidly dividing group of cells that develops around the fifth or sixth day after fertilization.
Not every retrieved egg will become a transferable embryo.
There can be a natural reduction in numbers at each stage:
Eggs retrieved → mature eggs → fertilized eggs → developing embryos → embryos suitable for transfer or freezing
This is one reason fertility treatment outcomes cannot be predicted simply from the number of eggs retrieved.
Step 6: Embryo Transfer
Embryo transfer is the procedure in which a selected embryo is placed into the uterus using a thin, flexible catheter passed through the cervix.
Mayo Clinic states that embryo transfer often takes place approximately 2 to 6 days after egg collection, depending on the treatment approach and embryo development.
During embryo transfer:
- A thin catheter is passed through the vagina and cervix.
- The catheter reaches the uterus.
- The selected embryo is placed into the uterus in a small amount of fluid.
- The catheter is removed.
Cleveland Clinic describes embryo transfer as a laboratory-to-uterus step in which an embryo is transferred through a catheter after fertilization and embryo development.
The IVF treatment process includes ovarian stimulation, monitoring, egg retrieval, fertilization, embryo development and embryo transfer. Cleveland Clinic’s IVF treatment guide also explains these stages and how procedures such as ICSI may be used in selected situations.
The number of embryos transferred is an important discussion between the patient and fertility team because transferring multiple embryos can increase the chance of a multiple pregnancy. Mayo Clinic notes that the number selected depends on factors including age, embryo factors and clinical circumstances.
Fresh vs Frozen Embryo Transfer
Not every IVF cycle involves an immediate fresh embryo transfer.
In some treatment plans, embryos are frozen and transferred during a later cycle. This is called a frozen embryo transfer, or FET.
The decision depends on the treatment protocol, embryo development, uterine preparation and the patient’s individual circumstances.
Your fertility specialist can explain whether a fresh or frozen transfer is more appropriate for your treatment plan.
Step 7: Pregnancy Testing
A pregnancy test is performed after embryo transfer to determine whether implantation has resulted in pregnancy.
The timing of the test depends on the clinic’s protocol and the type of transfer performed.
Mayo Clinic notes that a blood test is generally performed at least 12 days after egg retrieval to determine whether pregnancy has occurred.
A blood test measures human chorionic gonadotropin (hCG), a hormone produced after implantation.
If the result is positive, your fertility team will advise you about follow-up testing and early pregnancy care.
If the result is negative, your doctor can discuss what the result means and whether another treatment cycle or a different approach should be considered.
What Can Affect the Chance of a Successful Pregnancy With IVF?
The chance of a successful pregnancy with IVF varies between individuals and depends on factors such as age, the cause of infertility, ovarian reserve, embryo development and other medical factors. There is no single IVF success rate that accurately predicts an individual’s outcome.
Mayo Clinic states that IVF outcomes depend on factors including age and the cause of infertility.
Cleveland Clinic also notes that IVF success depends on individual factors such as age, ovarian reserve, the reason for infertility and previous pregnancy history.
Important factors include:
- Age
- Ovarian reserve
- Egg and embryo factors
- Sperm factors
- Cause of infertility
- Previous fertility treatment
- Uterine and reproductive health
- Individual medical conditions
For this reason, a clinic’s headline success percentage should not be interpreted as a guaranteed outcome for an individual patient.
A fertility specialist can give you a more meaningful assessment after reviewing your medical history and investigations.
IVF Treatment vs IUI
IVF and IUI are different fertility treatments. IUI places prepared sperm directly into the uterus around the time of ovulation, while IVF involves retrieving eggs, fertilizing them in a laboratory and transferring an embryo into the uterus.
The choice between IUI and IVF depends on factors such as the cause of infertility, age, sperm factors, tubal health, previous treatment and the patient’s reproductive goals.
If you are deciding between the two, read our detailed guide to IUI vs IVF fertility treatment.
The decision should be made with a fertility specialist rather than based on a single success-rate comparison.
What Happens to Extra Embryos?
If more than one embryo develops appropriately, embryos that are not transferred may sometimes be frozen and stored for future treatment.
Mayo Clinic notes that extra embryos can be frozen and stored for future use.
Cryopreservation can allow patients to use suitable embryos in a later frozen embryo transfer without repeating ovarian stimulation and egg retrieval for that embryo.
Whether embryos are frozen, how they are stored and how they may be used depends on the patient’s treatment plan and applicable clinical and legal requirements.
What Are the Common Side Effects and Risks of IVF?
IVF is generally performed under medical supervision, but it involves medicines and procedures that can have side effects and risks. The risks vary depending on the medicines used, the patient’s health and the procedures performed.
Possible effects during an IVF cycle can include:
- Bloating
- Abdominal or pelvic discomfort
- Injection-site reactions
- Breast tenderness
- Mood changes
- Cramping after egg retrieval
- Mild bleeding or discharge after embryo transfer
More significant complications can occur.
One important complication is ovarian hyperstimulation syndrome (OHSS), in which the ovaries respond excessively to stimulation medicines.
Mayo Clinic advises contacting the care team for moderate or severe pain or heavy vaginal bleeding after embryo transfer, as these symptoms can require assessment for complications.
Your fertility team should explain the specific risks associated with your medicines and treatment protocol.
How to Prepare for an IVF Cycle
Preparing for IVF involves more than remembering medication schedules. Good preparation can help you understand the process and stay organized during a cycle.
Before starting treatment:
- Keep a record of your current medicines and supplements.
- Complete the investigations recommended by your fertility team.
- Understand when monitoring appointments are scheduled.
- Ask how and when each medicine should be taken.
- Discuss any existing medical conditions with your doctor.
- Ask which activities are appropriate during ovarian stimulation.
- Plan practical support around egg retrieval and other procedures.
- Prepare a list of questions for your fertility consultation.
Your doctor may also recommend specific lifestyle changes based on your medical history.
There is no single diet, supplement or lifestyle intervention that can guarantee a successful pregnancy through IVF.
Can Integrative Fertility Care Be Part of IVF Preparation?
Arka Health describes its fertility care as an integrative model that combines conventional fertility treatment with personalized assessment, nutrition, lifestyle and supportive approaches.
These approaches should be viewed as supportive care rather than replacements for evidence-based fertility treatment.
For example, nutrition, sleep, physical activity and emotional support may form part of overall health management. Whether any additional therapy is appropriate depends on the individual patient’s medical situation.
If you are interested in a broader approach to fertility health, you can explore integrative fertility care at Arka Health.
Arka Anugraha Hospital's Approach to Fertility Care
At Arka Anugraha Hospital in Bangalore, fertility care is presented as a personalized and multidisciplinary process that combines conventional fertility treatment with the hospital’s integrative and functional medicine approach.
The hospital’s current website identifies Dr. Saraswathi Ramesh as an Obstetrician and Gynaecologist and Urogynaecologist, with an M.D. in Obstetrics and Gynecology and expertise in advanced video laparoscopic surgery. Her profile also lists qualifications in naturopathy and yoga.
Arka’s broader women’s health services include fertility and infertility care alongside gynecological services.
For patients considering IVF, the important question is not simply which clinic performs IVF, but whether the treatment plan is appropriate for the individual’s age, diagnosis, reproductive goals and medical needs.
Frequently Asked Questions (FAQ)
A typical IVF cycle can take about 2 to 3 weeks once preparation is complete, according to Mayo Clinic. The overall timeline can be longer if treatment involves additional preparation, a frozen embryo transfer or other individualized steps.
