In Vitro Fertilization (IVF)
Trusted by Patients From 35+ Countries
What is In Vitro Fertilization (IVF)?
In Vitro Fertilization (IVF) is an advanced assisted reproductive technology (ART) that helps couples conceive a child. In this process, a woman’s eggs are retrieved and fertilized with sperm in a laboratory. The resulting embryo is then transferred into the uterus for implantation and pregnancy. IVF is one of the most effective fertility treatments available today.
Why is IVF Treatment Done?
IVF treatment is recommended for couples facing infertility or reproductive challenges, including:
- Blocked or damaged fallopian tubes
- Male infertility (low sperm count or motility)
- Ovulation disorders
- Endometriosis
- Unexplained infertility
- Genetic disorders (to prevent transmission)
- Advanced maternal age
IVF offers hope to couples who have not succeeded with other fertility treatments.
Who is an Eligible Candidate for IVF Treatment in India?
You may be eligible for IVF treatment if:
- You have been trying to conceive for over a year without success
- You have known fertility issues (male or female)
- You are a woman with healthy ovaries but unable to conceive naturally
- You require donor eggs, sperm, or embryos
- You are planning pregnancy at an advanced age
- You want to preserve fertility (egg freezing before medical treatment)
A fertility specialist evaluates medical history, hormone levels, and reproductive health before recommending IVF.
Types of IVF Treatment
Different IVF techniques are available based on individual needs:
- Conventional IVF – Standard fertilization in a lab
- ICSI (Intracytoplasmic Sperm Injection) – A single sperm is injected directly into an egg
- Frozen Embryo Transfer (FET) – Previously frozen embryos are used
- Donor Egg or Sperm IVF – For patients with reproductive challenges
- Preimplantation Genetic Testing (PGT) – Screening embryos for genetic conditions
1. Conventional IVF (Standard Fertilization in a Lab)
Conventional IVF is the most commonly used fertility treatment where eggs and sperm are combined in a controlled laboratory environment to allow natural fertilization.
Process:
- Ovarian stimulation using fertility medications
- Egg retrieval from the ovaries
- Sperm sample collection
- Eggs and sperm are placed together in a culture dish
- Fertilization occurs naturally
- Embryo transfer into the uterus
Best For:
- Couples with unexplained infertility
- Mild male infertility
- Women with ovulation disorders
Advantages:
- Less invasive compared to ICSI
- Mimics natural fertilization
- Cost-effective option
2. ICSI (Intracytoplasmic Sperm Injection)
ICSI is an advanced IVF technique where a single healthy sperm is directly injected into an egg to ensure fertilization.
Process:
- Egg retrieval similar to IVF
- Selection of a high-quality sperm
- Direct injection into the egg using a microneedle
- Embryo development and transfer
Best For:
- Severe male infertility (low sperm count or poor motility)
- Previous IVF failures
- Use of frozen or surgically retrieved sperm
Advantages:
- Higher fertilization rates in male infertility cases
- Requires fewer sperm
- Improves chances of successful embryo formation
3. Frozen Embryo Transfer (FET)
Frozen Embryo Transfer involves using embryos that were created in a previous IVF cycle and cryopreserved for future use.
Process:
- Embryos are frozen after fertilization
- Uterine lining is prepared in a later cycle
- Frozen embryos are thawed and transferred
Best For:
- Patients with surplus embryos
- Women needing delayed embryo transfer
- Those undergoing fertility preservation
Advantages:
- Less physically demanding (no egg retrieval required)
- Higher flexibility in timing
- Often improved success rates due to better uterine preparation
4. Donor Egg or Sperm IVF
This method uses eggs or sperm from a donor when one partner is unable to produce viable reproductive cells.
Process:
- Selection of screened donor (egg or sperm)
- Fertilization via IVF or ICSI
- Embryo transfer into the recipient’s uterus
Best For:
- Women with low ovarian reserve or poor egg quality
- Premature ovarian failure
- Male infertility (in case of donor sperm)
- Genetic disorders in either partner
Advantages:
- Higher success rates in certain cases
- Expands options for conception
- Safe and regulated donor screening process
5. Preimplantation Genetic Testing (PGT)
PGT is a specialized technique used to test embryos for genetic abnormalities before implantation.
Process:
- IVF cycle to create embryos
- A few cells are biopsied from the embryo
- Genetic analysis is performed
- Only healthy embryos are selected for transfer
Best For:
- Couples with a history of genetic disorders
- Recurrent IVF failures
- Repeated miscarriages
- Advanced maternal age
Advantages:
- Reduces risk of genetic diseases
- Improves chances of healthy pregnancy
- Lowers risk of miscarriage
Diagnostic Tests Done Before IVF Treatment
Before starting IVF, several tests are conducted:
- Hormone level tests (AMH, FSH, LH)
- Ultrasound scans
- Semen analysis
- Infectious disease screening
- Hysteroscopy or laparoscopy (if needed)
- Genetic testing (in selected cases)
These tests help create a personalized and effective IVF treatment plan.
