Intracytoplasmic Sperm Injection (ICSI) is an advanced fertility treatment used to address male infertility and improve fertilization outcomes in IVF. It involves the direct injection of a single healthy sperm into an egg, increasing the chances of successful embryo development. This blog will guide you through each step of the ICSI process, helping you understand what to expect during your fertility journey.

What is ICSI?

ICSI (Intracytoplasmic Sperm Injection) is a specialized form of In Vitro Fertilization (IVF) where a single sperm is directly injected into a mature egg. This method is particularly helpful for couples facing:

Step-by-Step process of the ICSI procedure

1. Initial consultation and Fertility assessment

6 Steps of the ICSI Procedure

Your journey begins with a thorough evaluation by our fertility specialists. We assess both partners through:

  • Hormonal blood tests.
  • Semen analysis.
  • Transvaginal ultrasound for women.
  • Detailed medical history and counseling.

This helps us design a treatment plan tailored to your needs.

2. Ovarian stimulation

The female partner is given fertility injections (gonadotropins) for 8–12 days to stimulate the ovaries and produce multiple mature eggs. During this phase:

  • Hormone levels are monitored.
  • Follicular growth is tracked via ultrasound.
  • Dosage is adjusted based on individual response.

3. Egg retrieval (Oocyte Pick-Up)

Once the follicles are mature, a trigger injection is given (usually hCG), and egg retrieval is scheduled 34–36 hours later.

  • The procedure is done under mild sedation.
  • Eggs are collected using a fine needle guided by ultrasound.
  • It is a day-care procedure with quick recovery.

4. Sperm collection and Preparation

On the day of egg retrieval:

  • The male partner provides a semen sample.
  • In cases of azoospermia, sperm is surgically retrieved (TESA/PESA)
  • The sperm is washed and prepared in the lab for ICSI.

5. ICSI fertilization

This is the most critical stage of the process:

  • A single healthy sperm is selected and injected directly into each mature egg using a microneedle.
  • This is performed under a high-powered microscope by an embryologist.
  • The injected eggs are then monitored for fertilization over the next 18–20 hours.

6. Embryo culture and Monitoring

  • Successfully fertilized eggs develop into embryos.
  • Embryos are cultured for 3–5 days. (until Day 3 or Day 5 – blastocyst stage)
  • The best quality embryos are selected for transfer.

7. Embryo transfer

  • A selected embryo is gently transferred into the uterus using a soft catheter.
  • This is a painless, outpatient procedure.
  • Any remaining good-quality embryos can be frozen for future use. (cryopreservation)

8. Luteal phase support

After embryo transfer, hormonal medications (progesterone and others) are prescribed to support the uterine lining and increase chances of implantation.

9. Pregnancy test and Follow-up

Approximately 12–14 days after embryo transfer, a blood test (beta-hCG) is done to confirm pregnancy. If positive, early pregnancy scans are scheduled to monitor development.
