Comparision Between IVF IUI & ICSI

In vitro fertilization (IVF), intrauterine insemination (IUI), and intracytoplasmic sperm injection (ICSI) are all assisted reproductive technologies (ART) used to address fertility issues, but they differ in their procedures and applications. Here's a comparison between IVF, IUI, and ICSI:

IVF (In Vitro Fertilization)


  • In IVF, eggs and sperm are collected from the woman and man, respectively.
  • Fertilization occurs outside the body in a laboratory dish.
  • Embryos are cultured for a few days before one or more are transferred into the woman's uterus.


  • Blocked fallopian tubes, severe male infertility, endometriosis, unexplained infertility, or after failed IUI attempts.

Success Rates

  • Success rates vary but can be higher than IUI, especially in cases of severe infertility.

IUI (Intrauterine Insemination)


  • Sperm is processed and placed directly into the woman's uterus around the time of ovulation.
  • Timing is crucial to increase the chances of sperm meeting the egg.


  • Mild male infertility, cervical mucus issues, or unexplained infertility.

Success Rates

  • Success rates are generally lower than IVF, and multiple cycles may be needed.

ICSI (Intracytoplasmic Sperm Injection)


  • ICSI is a variation of IVF where a single sperm is directly injected into an egg.
  • It is particularly useful in cases of severe male infertility or when previous IVF cycles have resulted in fertilization failure.


  • Male factor infertility, low sperm count, poor sperm motility, or abnormal sperm morphology.

Success Rates

  • ICSI can significantly improve fertilization rates in cases of severe male infertility.


Fertilization Process:

  • In IVF, fertilization occurs outside the body.
  • In IUI, fertilization happens inside the woman's body.
  • In ICSI, a single sperm is injected directly into an egg in the laboratory.


  • IVF is suitable for various infertility issues, including severe male infertility and blocked fallopian tubes.
  • IUI is often used for mild male infertility, cervical mucus problems, or unexplained infertility.
  • ICSI is specifically designed for cases of severe male infertility.

Success Rates:

  • IVF and ICSI generally have higher success rates compared to IUI.
  • Success rates vary based on factors such as age, the cause of infertility, and the health of the individuals involved.

Complexity and Invasiveness:

  • IVF is more complex and involves multiple steps, including ovarian stimulation, egg retrieval, fertilization in the laboratory, and embryo transfer.
  • IUI is less complex and invasive than IVF.
  • ICSI is an additional step within the IVF process, involving the direct injection of sperm into eggs.
