Understanding Intracytoplasmic Sperm Injection (ICSI)


Intracytoplasmic Sperm Injection (ICSI) is a specialized form of In Vitro Fertilization (IVF) that offers hope to couples facing severe male infertility issues. It involves the direct injection of a single sperm into an egg to facilitate fertilization, followed by the transfer of the resulting embryo to the woman's uterus.We aim to provide comprehensive information about ICSI, its procedures, and how it can help you achieve your dream of parenthood.

The ICSI Process

1. Consultation and Evaluation:

The process begins with a thorough consultation and evaluation to understand your specific needs and medical history. Our specialists will guide you through the options available and help you make an informed decision.

2. Ovarian Stimulation:

Hormonal medications are administered to stimulate the ovaries and increase the number of available eggs. This phase is closely monitored through blood tests and ultrasound examinations to track follicle development.

3. Egg Retrieval:

Once the follicles have matured, a minor surgical procedure called egg retrieval is performed under ultrasound guidance. A thin needle is used to extract the eggs from the ovaries, usually under sedation.

4. Sperm Collection

On the same day as egg retrieval, a semen sample is collected from the male partner. In cases of severe male infertility, sperm may be retrieved directly from the testes or epididymis through a surgical procedure.

5. Sperm Preparation:

The collected sperm is processed and prepared for injection. The best-quality sperm are selected for the ICSI procedure.

6. Sperm Injection:

A single sperm is directly injected into each mature egg using a fine needle under a microscope. This precise technique helps overcome fertilization barriers that may be present in traditional IVF.

7. Embryo Culture:

The fertilized eggs (now embryos) are cultured in a controlled environment for several days. The embryologists monitor their development, selecting the most viable embryos for transfer.

8. Embryo Transfer:

A selected embryo is transferred into the woman’s uterus using a thin catheter. This procedure is usually painless and does not require anesthesia.

9. Luteal Phase Support:

Hormonal medications are given to support the uterine lining and enhance the chances of successful implantation and pregnancy.

10. Pregnancy Test:

About two weeks after the embryo transfer, a blood test is conducted to determine if pregnancy has been achieved.

Indications for ICSI

ICSI is recommended for various infertility issues, including:

  • Severe Male Factor Infertility: Low sperm count, poor sperm motility, or high percentage of abnormally shaped sperm.
  • Previous IVF Failure: Couples who have had poor or no fertilization in previous IVF cycles.
  • Obstructive Azoospermia: Blockages preventing sperm from being present in the ejaculate.
  • Non-Obstructive Azoospermia: Conditions where no sperm is produced in the ejaculate due to genetic or medical factors.
  • Egg Fertilization Issues: When traditional IVF fertilization methods are not successful.
  • Genetic Disorders: Couples at risk of passing on genetic conditions may use ICSI with preimplantation genetic testing (PGT).

Success Rates and Factors

The success rates of ICSI vary depending on several factors, including:

  • Age: Younger women typically have higher success rates due to better egg quality.
  • Cause of Infertility: Certain conditions may affect the likelihood of success.
  • Lifestyle: Maintaining a healthy lifestyle, including proper diet and avoiding smoking and excessive alcohol, can improve outcomes.
