🧬 IVF vs ICSI vs IUI — Which Fertility Treatment Is Right for You?

A Complete Guide by India’s Leading Fertility Experts

🌸 Introduction

If you’re struggling to conceive, you’ve probably heard your doctor mention terms like IVF, ICSI, and IUI.
They sound similar — and all aim to help couples achieve pregnancy — but they differ in how they work, who they’re meant for, and their success rates.

At Zeeva Fertility, we meet hundreds of couples each month from across the world — the Middle East, Africa, and the UK — who ask the same question:

“Which fertility treatment is best for us — IVF, ICSI, or IUI?”

This article breaks down the three treatments in simple terms — explaining how each works, who it’s suitable for, and what kind of results you can expect.

“Choosing the right fertility treatment isn’t about what’s most popular — it’s about what’s most appropriate for your unique case.”
— Dr. Aarthi Mani , Senior Reproductive Medicine Specialist

🧫 What Is IUI (Intrauterine Insemination)?

IUI, or Intrauterine Insemination, is one of the simplest and least invasive fertility treatments.

💡 How It Works:

  • During ovulation, washed and concentrated sperm are directly inserted into the woman’s uterus using a thin catheter.

  • This helps sperm reach the egg faster, increasing the chances of natural fertilization.

👩‍⚕️ Best For:

  • Couples with mild male infertility (slightly low sperm count or motility)

  • Unexplained infertility

  • Cervical issues or mild ovulation problems

📊 Success Rate:

  • Average 15–20% per cycle (higher in younger women)

💰 Cost in India:

  • $250–$400 per cycle, making it one of the most affordable fertility options.

“Think of IUI as giving nature a little push — it’s simple, safe, and often the first step before IVF.”

🧬 What Is IVF (In Vitro Fertilization)?

IVF, or In Vitro Fertilization, is the most well-known fertility treatment worldwide.

💡 How It Works:

  • The woman takes medications to stimulate egg production.

  • Mature eggs are retrieved and fertilized with sperm in a lab dish (in vitro).

  • After fertilization, healthy embryos are cultured and transferred into the uterus.

👩‍⚕️ Best For:

  • Blocked or damaged fallopian tubes

  • Severe endometriosis

  • Unexplained infertility

  • Couples who failed to conceive after multiple IUI attempts

📊 Success Rate:

  • 50–70% per cycle (varies by age, egg/sperm quality, and clinic expertise)

💰 Cost in India:

  • $2,800–$4,000 per cycle, about 60–70% less than in the USA or UK.

“IVF gives doctors full control over fertilization — offering hope even when natural conception seems impossible.”
— Dr. Aarthi Mani, IVF Director

💉 What Is ICSI (Intracytoplasmic Sperm Injection)?

ICSI is an advanced form of IVF designed specifically to help overcome male infertility issues.

💡 How It Works:

  • Instead of mixing eggs and sperm in a dish, a single healthy sperm is directly injected into each egg using a fine needle under a microscope.

  • Once fertilization occurs, the resulting embryo is transferred into the uterus — just like in standard IVF.

👩‍⚕️ Best For:

  • Severe male infertility (low count, poor motility, abnormal shape)

  • Previous IVF failure due to poor fertilization

  • Frozen sperm samples or surgical sperm extraction cases

📊 Success Rate:

  • 60–75% per cycle (often higher than standard IVF in male infertility cases)

💰 Cost in India:

  • $3,000–$4,500 per cycle, depending on lab technology and medication dosage.

“ICSI allows even a single healthy sperm to create life — a revolution for couples facing male infertility.”
— Dr. Sandeep, Chief Embryologist
