IUI vs IVF: Difference and Comparison

Probably the greatest distinction between IUI and IVF is the place where preparation really happens. With IUI, treatment (insemination of an egg with sperm) is happening inside a lady’s body.

Key Takeaways

  1. IUI injects sperm directly into the uterus, while IVF involves combining eggs and sperm in a laboratory dish and then transferring the resulting embryo into the uterus.
  2. IUI is less invasive and less expensive than IVF.
  3. IVF is more successful than IUI, especially for couples with fertility problems.


Intrauterine insemination (IUI) is an artificial procedure for infertile couples where washed sperm are directly inserted into a woman’s womb during her ovulation period. IUI can be an affordable option for conception. The rate of pregnancy is lower. In vitro fertilisation (IVF) is an intrusive procedure where mature eggs and sperm are artificially fertilised in a lab. The pregnancy rate is higher in IVF procedures.


IUI is a basic office strategy that places sperm, gathered from the accomplice and prepared in the lab, into the uterine cavity. The “washing” of sperm in the lab eliminates fundamental liquid (which can cause serious squeezing) and focuses the sperm.

Before the preparation can happen, the lady takes fruitfulness medicine to invigorate the ovaries to aid in effective egg recovery. The egg recovery is performed under sedation, and insemination is played out that very day.

For instance, a low sperm count or helpless sperm well-being can bring about the requirement for an IUI to sidestep sex and inseminate the female to join forces with a powerful sperm test to expand the chances of a fruitful pregnancy.

Indeed, ladies between the ages of 20 and 30 have about a 20% achievement pace of getting pregnant utilizing a blend of rich prescriptions and an IUI method.

Studies show that the best achievement rates come from endeavouring something like 3 IUI cycles while seeking rich medicines.

What is IVF?

In vitro fertilization (IVF) is a high-level strategy where a few female eggs are separated from the ovaries and are prepared with a sperm test within a controlled climate until solid incipient organisms are created.

The whole methodology is done in-house at a rich facility, and couples can decide to freeze any excess incipient organisms on the off chance that an IVF cycle is fruitless.

In 2015, ladies younger than 35 had more than a 40% shot at having an effective pregnancy, and even ladies in their mid-40s had considerable achievement rates, just shy of 20%.

Other conceptive issues or well-being concerns, like uterine fibroids, ovarian brokenness, or a past filled with barrenness for the two accomplices, can keep an IVF method from working.
