What is the difference between IVF and IUI?

When couples face difficulty conceiving naturally, fertility treatments such as IUI (Intrauterine Insemination) and IVF (In Vitro Fertilization) are commonly recommended. While both aim to help achieve pregnancy, they differ in process, success rates, cost, and suitability. Understanding the difference between IVF and IUI can help couples choose the right treatment with guidance from a fertility specialist.

What Is IUI?

IUI, or Intrauterine Insemination, is a fertility treatment where specially prepared sperm is placed directly into the uterus around the time of ovulation. This increases the chances of sperm reaching the egg naturally.

How IUI Works

  • Ovulation is tracked or stimulated with medication
  • Semen is collected and washed in a lab
  • Healthy sperm is inserted into the uterus using a thin catheter

Who Is IUI Suitable For?

IUI is often recommended for:

  • Mild male factor infertility
  • Unexplained infertility
  • Cervical factor infertility
  • Couples trying for a shorter duration
  • Women with regular ovulation

An experienced IUI treatment centre in Delhi ensures accurate timing and proper sperm preparation, which are key to IUI success.

What Is IVF?

IVF, or In Vitro Fertilisation, is an advanced fertility treatment where eggs and sperm are fertilised in a laboratory. The resulting embryo is then transferred into the uterus.

How IVF Works

  • Ovarian stimulation to produce multiple eggs
  • Egg retrieval under medical guidance
  • Fertilisation of eggs in a lab
  • Embryo culture and selection
  • Embryo transfer into the uterus

At a well-equipped IVF centre in Delhi, advanced technology and personalised protocols help improve IVF success rates.

Success Rates: IVF vs IUI

IUI success rates depend on age and fertility factors and are generally lower than IVF. IVF offers higher success rates, especially for:

  • Advanced maternal age
  • Blocked fallopian tubes
  • Severe male infertility
  • Endometriosis
  • Repeated IUI failures

When Should You Choose IUI?

IUI may be the first-line treatment if:

  • Infertility is mild
  • The woman is under 35
  • Fallopian tubes are open
  • Semen parameters are near normal

When Is IVF the Better Option?

IVF is often recommended when:

  • IUI cycles have failed
  • Tubes are blocked or damaged
  • Endometriosis is present
  • Egg or sperm quality is poor
  • The woman is over 35

A trusted IVF centre in Delhi can customise treatment to maximise outcomes.

Emotional and Time Considerations

IUI is less stressful and quicker, while IVF requires more time, monitoring, and emotional commitment. Choosing the right treatment depends on medical advice, age, fertility history, and personal comfort.

Conclusion

Both IVF and IUI are effective fertility treatments, but they serve different needs. IUI is simpler and less invasive, while IVF offers higher success rates for complex fertility challenges.

Consulting a reputable IVF centre like SCI IVF Hospital ensures accurate diagnosis, personalised treatment planning, and compassionate support throughout the fertility journey. With expert guidance, couples can confidently choose the path that best suits their needs.
