ICSI Treatment in Chandigarh for Infertility

Your fertility specialist may recommend Intracytoplasmic Sperm Injection (ICSI) in the following situations:

• Low sperm count (Oligozoospermia): When the number of sperm is too low to achieve reliable fertilization through conventional IVF.
• Poor sperm motility (Asthenozoospermia): When sperm cannot swim effectively to reach and fertilize the egg.
• Abnormal sperm morphology (Teratozoospermia): When a significant proportion of sperm have abnormal size or shape.
• Azoospermia: When sperm must be retrieved surgically through procedures such as TESA, PESA, or TESE.
• High sperm DNA fragmentation: When sperm DNA damage may reduce fertilization or embryo development.
• Previous fertilization failure with IVF: If a previous conventional IVF cycle resulted in poor or no fertilization.
• Use of frozen or cryopreserved sperm: To maximise the chances of successful fertilization with banked sperm samples.
• Limited number of retrieved eggs: When only a few mature eggs are available, making optimal fertilization especially important.
• Preimplantation Genetic Testing (PGT): To minimise the risk of sperm contamination during genetic testing of embryos.
• Donor egg or donor sperm treatment cycles: When ICSI is clinically indicated as part of an assisted reproduction plan.

An ICSI cycle involves several carefully planned steps that are coordinated between the fertility specialist and the embryology laboratory.:

1. Ovarian Stimulation

The female partner receives daily hormone injections for approximately 8–12 days to stimulate the ovaries to produce multiple mature eggs. The fertility team monitors follicle growth through regular ultrasound scans and blood tests. 

2. Trigger Injection 

When the follicles reach the desired maturity, a trigger injection is administered to complete the final stage of egg maturation. Egg retrieval is usually scheduled 34–36 hours later. 

3. Egg Retrieval 

Egg retrieval is a short procedure performed under sedation. Using ultrasound guidance, the doctor passes a fine needle through the vaginal wall to collect the mature eggs from the ovaries. The procedure usually takes 25–30 minutes, and most patients return home the same day. 

4. Sperm Collection & Preparation 

A fresh semen sample is collected on the day of egg retrieval, or a previously frozen sample is thawed. If the male partner has azoospermia (absence of sperm in the ejaculate), sperm may be retrieved surgically from the epididymis or testicle using procedures such as PESA or TESA. The laboratory then processes the sample to identify the healthiest sperm for injection. 

5. Intracytoplasmic Sperm Injection (ICSI) 

Under a high-magnification microscope, the embryologist selects a single healthy sperm and injects it directly into the centre of each mature egg using an ultra-fine glass needle. This step requires exceptional precision and forms the key difference between ICSI and conventional IVF. 

6. Fertilization Check 

The following day, the embryology team examines the eggs to confirm normal fertilization. It is important to understand that not every injected egg will fertilize, and this can occur even in well-managed treatment cycles. 

7. Embryo Culture & Grading 

The fertilized eggs are cultured in specialised incubators for 3–5 days. Embryologists monitor embryo development daily and grade the embryos based on their growth and appearance. In many cases, embryos are cultured to the blastocyst stage (Day 5) to help select the embryo with the highest implantation potential. 

8. Embryo Transfer 

The selected embryo is gently transferred into the uterus using a thin, soft catheter. The procedure is usually painless and does not require anaesthesia. 

9. Luteal Support & Pregnancy Test 

After embryo transfer, progesterone support is provided to help prepare and maintain the uterine lining. A blood pregnancy test (beta-hCG) is performed 12–14 days later to determine whether implantation and pregnancy have occurred. 

ICSI has helped improve fertilization outcomes for many couples with male factor infertility. However, like all fertility treatments, its success depends on several medical and laboratory factors rather than the procedure alone. 

Sperm Quality 

Although ICSI bypasses the sperm's natural journey to the egg, the quality of the selected sperm remains important. Sperm morphology, motility, and DNA integrity can all influence fertilization, embryo development, and the likelihood of a successful pregnancy. 

Egg Quality 

Egg quality is one of the strongest predictors of ICSI success, as it decides the embryo development after fertilization. It is closely linked to the woman's age, ovarian reserve, and overall reproductive health. 

Embryologist Skill & Lab Standards 

ICSI is a highly specialized laboratory procedure that requires exceptional precision. Fertilization outcomes depend on the embryologist's expertise, advanced micromanipulation equipment, and carefully controlled laboratory conditions that support healthy embryo development. 

Female Reproductive Health

ICSI improves the fertilization process but does not address other female fertility factors. The health of the uterus, endometrial receptivity, hormonal balance, and underlying reproductive conditions continue to influence implantation and pregnancy outcomes. 

Cause of Male Infertility 

Men requiring surgically retrieved sperm, such as those with azoospermia, may have different fertilization outcomes than those using ejaculated sperm. However, ICSI remains one of the most effective treatment options for overcoming severe male factor infertility. 

ICSI has transformed the treatment of male infertility by enabling successful fertilization even in situations where conventional IVF may not be effective. Depending on the underlying fertility condition, its advantages include: 

• Improves fertilization rates in many cases of moderate to severe male infertility
• Makes pregnancy possible even when only a small number of healthy sperm are available
• Enables fertilization using surgically retrieved sperm in men with obstructive or non-obstructive azoospermia
• Reduces the likelihood of fertilization failure in couples with a previous unsuccessful IVF cycle
• Can be combined with preimplantation genetic testing (PGT) when clinically indicated
• Suitable for treatment cycles using frozen sperm, donor sperm, or donor eggs
• Requires only a single viable sperm to fertilize each mature egg
• Offers an effective treatment option for a wide range of male factor infertility conditions

Like all assisted reproductive techniques, ICSI has certain limitations and potential risks. However, when performed by experienced fertility specialists and skilled embryologists in a well-equipped laboratory, serious complications are uncommon.

Potential considerations include:

• Not every injected egg will fertilize or develop into a healthy embryo.
• The overall success of treatment continues to depend on factors such as the woman's age, egg quality, embryo quality, and uterine health.
• Rarely, an egg may be damaged during the injection process despite meticulous laboratory techniques.
• Surgical sperm retrieval procedures such as TESA or PESA carry small risks of pain, bruising, bleeding, or infection.
• Multiple pregnancy remains a possibility if more than one embryo is transferred, although this risk can be reduced by following evidence-based embryo transfer recommendations.
