Step-by-Step ICSI Procedure: Cost, Success Rate, Risks & IVF Guide

Infertility is a growing concern for couples worldwide, and understanding infertility symptoms is often the first step toward timely treatment.

Many couples explore options like IUI and IVF treatment when natural conception does not happen as expected. Conditions such as unexplained infertility and male infertility can make the journey emotionally and physically challenging.

Advanced procedures involve IVF treatment injections, careful monitoring, and awareness of possible embryo transfer symptoms after the procedure.

At the same time, factors like IVF treatment cost play a crucial role in decision-making for families. Along with medical intervention, lifestyle changes and foods to increase fertility are often recommended to support reproductive health.

Every fertility journey is unique, and outcomes depend on age, diagnosis, and overall health. Modern fertility care combines science, nutrition, and emotional support to improve success rates.

With the right information, couples can make informed choices and feel more prepared. But how do you know which fertility treatment path is truly right for you?

What is ICSI (Intracytoplasmic Sperm Injection)?

ICSI is a specialized form of IVF in which a single sperm is directly injected into a mature egg using advanced microscopic equipment. Unlike conventional IVF, where fertilization occurs naturally in a lab dish, ICSI bypasses several natural barriers to fertilization.

The procedure is performed by a highly trained embryologist using micromanipulation tools under a powerful microscope. Once fertilization occurs, the embryo is cultured in the laboratory and later transferred into the uterus.

ICSI was originally developed to treat severe male infertility but is now used in a wide range of fertility cases.

Who is an Ideal Candidate for ICSI?

ICSI is commonly recommended in the following situations:

• Low sperm count (oligospermia)
• Poor sperm motility (asthenozoospermia)
• Abnormal sperm morphology (teratozoospermia)
• Azoospermia requiring surgical sperm retrieval (TESA, PESA, TESE)
• Previous IVF fertilization failure
• Use of frozen sperm
• Unexplained infertility
• Advanced maternal age
• Fertility preservation cases

Doctors may recommend ICSI even when sperm parameters appear normal, especially if fertilization failure has occurred in a previous IVF cycle.

ICSI Procedure Step by Step (Complete Process):

Step 1: Initial Consultation and Fertility Evaluation

The process begins with a detailed fertility assessment of both partners.

For the female partner:

• Hormone tests (AMH, FSH, LH, Estradiol)
• Transvaginal ultrasound
• Ovarian reserve testing
• Uterine evaluation

For the male partner:

• Semen analysis
• DNA fragmentation test (if required)
• Hormonal profile

These tests help doctors design a personalized stimulation and fertilization plan.

Step 2: Ovarian Stimulation

The female partner receives hormonal injections to stimulate the ovaries to produce multiple eggs in one cycle.

• Injections usually last 10–12 days
• Regular ultrasound and blood tests monitor follicle growth
• Final trigger injection is given to mature the eggs

This stage is crucial, as egg quality directly affects ICSI success.

Step 3: Egg Retrieval (Oocyte Pick-Up)

Egg retrieval is a short, minimally invasive procedure performed under mild anesthesia.

• Duration: 15–30 minutes
• Eggs are collected using a thin ultrasound-guided needle
• Recovery is usually same day

Most women experience mild cramping or bloating for 1–2 days.

Step 4: Sperm Collection and Preparation

Sperm can be obtained through:

• Ejaculation (fresh sample)
• Frozen sperm sample
• Surgical sperm retrieval (TESA / PESA / TESE)

The embryology lab selects the healthiest single sperm for injection.

Step 5: Fertilization via ICSI (Key Step)

This is the defining step of ICSI.

• Each mature egg is held with a micro-pipette
• One sperm is injected directly into the egg cytoplasm
• Eggs are placed in incubators for fertilization

Fertilization is checked after 16–18 hours.

Step 6: Embryo Development and Culture

Fertilized eggs are monitored for 3–5 days.

Embryo growth stages:

• Day 1: Fertilization confirmation
• Day 3: Cleavage-stage embryo
• Day 5: Blastocyst stage (preferred for transfer)

High-quality embryos are selected for transfer or freezing.

Step 7: Embryo Transfer

Embryo transfer is a painless, non-surgical procedure.

• Performed under ultrasound guidance
• Takes about 10–15 minutes
• No anesthesia required

Patients are advised to avoid strenuous activity for a few days.

ICSI Procedure Day-by-Day Timeline:

Day	What Happens
Day 1	Period begins, baseline ultrasound
Day 2–3	Ovarian stimulation injections start
Day 6–10	Follicle monitoring scans
Day 11–12	Trigger injection
Day 13–14	Egg retrieval
Day 14	Sperm injection (ICSI)
Day 15–19	Embryo culture
Day 19	Embryo transfer
Day 28	Pregnancy test

ICSI Success Rate: What are the Chances?

ICSI success rates depend on multiple factors, primarily female age and egg quality.

ICSI Success Rate by Female Age

Age Group	Average Success Rate
Below 35	50–60%
35–37	40–45%
38–40	30–35%
41–42	20–25%
Above 42	10–15%

Success rates may be higher with donor eggs.

ICSI Cost in India:

Average ICSI Cost Breakdown

Expense Component	Estimated Cost (INR)
Basic ICSI cycle	₹1.5–2.5 lakh
Medicines	₹60,000–1,20,000
Embryo freezing	₹30,000–50,000
Frozen embryo transfer	₹40,000–60,000
Surgical sperm retrieval	₹20,000–40,000

City-Wise Cost Range

City	Approximate Cost
Delhi / Mumbai	₹2.5–3.5 lakh
Bengaluru / Chennai	₹2–3 lakh
Ahmedabad / Pune	₹1.8–2.8 lakh
Tier-2 cities	₹1.5–2.2 lakh

ICSI Side Effects on Mother

Common Side Effects

• Bloating
• Mild abdominal pain
• Mood swings
• Breast tenderness
• Fatigue

Possible Medical Risks

• Ovarian Hyperstimulation Syndrome (OHSS)
• Infection or bleeding after egg retrieval
• Emotional stress and anxiety

Most side effects are temporary and manageable under medical supervision.

Are There Any Risks to the Baby with ICSI?

Current research shows that most children born via ICSI are healthy. However:

• Slightly increased risk of genetic abnormalities linked to severe male infertility
• Higher chance of multiple pregnancies if multiple embryos are transferred

Pre-implantation genetic testing (PGT) can reduce risks.

IVF or ICSI: Which One Should You Choose?

• IVF may be tried first if sperm quality is normal
• ICSI is preferred in male infertility or IVF failure
• Decision should be based on medical advice, not cost alone
