Embryo implantation after IUI is a crucial step for having a successful pregnancy. Signs of successful implantation after IUI are mainly cramping and spotting. You need to understand symptoms of embryo implantation after IUI procedure to consult your infertility specialist about successful occurrence of pregnancy.

If you are planning to undergo Intrauterine Insemination or IUI procedure then you must be trying to conceive since a while now. It is common nowadays as more and more women are turning to these methods. And a good way to understand this process is to know that this procedure is designed as a replica of natural conception process only with the twist that sperms are artificially injected in the Fallopian tubes.

When conceiving naturally, implantation is dependent on the woman’s period cycle. A normal cycle lasts for 28 days. If a woman conceives during her ovulation time, then she can expect implantation within 6 to 8 days after conception. But with IUI, the women’s period is closely observed for ensuring fertilization to take place with her ovulation. So implantation can occur even after 10 days post the IUI procedure.

What to Expect with Your First IUI:

What to do after IUI?

Gone are the days when bed rest was necessary to improve the conception chances after IUI. Though after IUI, it is quite common for the fertility clinics to make patients lie down for the next 10 to 15 minutes immediately after the IUI procedure. This is not for preventing the sperms to leak out. It is because the IUI catheter places the sample directly into woman’s uterus for letting the sperm stay in place.

1- Resting for a short period after IUI is a good idea if you feel a bit of cramp or light-headedness after the process. Although IUI is easy and a quick procedure but in some circumstances, women may feel some dizziness or discomfort. But once you are out of the treatment room, women can move back to their normal activities. Though it is okay to take a day off and give yourself rest. The procedure is emotionally intense even after being physically easy. What to do after iui

2- You should avoid strenuous activities, which require high-intensity exercises after IUI. It is also recommended after the IVF procedure. Your ovaries might be slightly proliferated, tender and needs to be protected if you have taken fertility medications for stimulating ovulation. It will keep the internal temperature low for providing a better environment for implantation. Bathing or swimming is not advised after IUI as there are chances of infection, which can be introduced through immersion in water.

How does it feel like after IUI?

Following IUI, it is observed that:

  • Women have a vaginal discharge. There is nothing to worry about it. It is not IUI leakage but cervical mucus, which dislodged during the procedure.
  • You will also experience slight spotting which is normal.
  • While some women will experience mild cramping and discomfort for some days after IUI. It doesn’t imply anything wrong but it means to take some extra time to rest and be kind to your body. You can also take painkillers like acetaminophen for relieving from cramps.
  • Contact your doctor immediately if you begin to experience bloating, bleeding or severe pain as it might indicate infection or rare side effects.

contact your doctor

  • Sex is allowed after the procedure and most of the times it is encouraged. As intercourse and orgasm will make the uterus to contract and helps in pushing the sperms towards the fallopian tubes and the egg. Your doctor will ask to wait for up to 48 hours directly after the procedure.

After IUI, how long it will take implantation to take place?

It is carefully observed and ensured to perform IUI within some hours of ovulation. But sometimes, depending on how regularly a woman ovulates, IUI may be performed near her natural cycles. In many cases, for stimulating the ovaries and to trigger ovulation small doses of fertility drugs are used for controlling the timing.

The ‘conception clock’ starts with ovulation because an egg is only viable for fertilization for 12 to 24 hours. It is important for sperm and egg to meet within this fertile phase to occur. The next step is for the fertilized egg to implant in uterus lining. This might take anywhere from 3 to 12 days. Usually, implantation takes place 9th day in 45% women who conceive after ovulation.

Signs of implantation after IUI

Implantation signs can be confusing and subtle. While some women become pregnant without any implantation signs and symptoms. These symptoms can be confused with early menstruation or can be side effects of IUI. Though it is very normal to feel implantation occurring. The most common implantation signs include:

1- Cramping- It is the most common implantation signs but is only reported in 30 to 35% of women who become pregnant. There can be slight cramp twinges or feeling of fullness in the abdomen. These can also signal the impending menstruation or can be due to IUI procedure. While some women experience implantation cramping as tingling or pinching beneath navel or slight gas pains.

2- Spotting- Some uterine cells are dislodged from lining once the blastocyst implants. And when you miss your menstrual cycles, you can see these dislodged cells discharging and appearing as slight spotting. Implantation spotting will be in light brown or pinkish in color rather than bright red like in period. This is an only minimal amount of blood. It can also be due to IUI catheter.


IUI – Frequently Asked Questions (FAQs)

1- How long before the IUI the sperm is collected?

It depends on the individual but it should not be more than 72 hours since male’s last ejaculation. It is because fresh semen ensures the best motility along with morphology. It is best to wait for 48 hours between ejaculation and sperm collection for IUI in case low sperm count is a reason for IUI.

2- What is the best timing for an IUI?

IUI should be performed within 6 hours either before or after ovulation. IUI is usually done between 24 to 48 hours later if the timing depends on hCG injection. And ideally, there is at least 24 hours gap if two IUI’s are scheduled.

3- What is the success rate for IUI?

Being a simple office procedure, the success rate of IUI for multiple cycles can go up to 50%.

4- How much does IUI cost?

IUI being the first choice for the infertility treatment can cost between $150-500 across the world. But there can be variation according to countries. There are multiple tests and medications involved in the treatment process.

You can also get an estimated amount charged for the treatment by using Fair Treatment Calculator across various cities in India.

5- How long does washed sperm live?

According to a study, washed sperm can live up to 24 to 72 hours but it loses potency after 24 hours. Plus the other point to consider is that the sperm can keep swimming beyond the fallopian tube. It implies the ideal window is between 6 to 12 hours after egg being released. Sperm can live for 5 days in fertile mucus. So, combining intercourse with IUI gives more coverage.

6- Can the sperm fall out after IUI?

Sperm does not fall out once it is injected into the uterus. However, there can be wetness after the IUI procedure. This usually happens when the catheter looses the mucus in the cervix hence the flow.

I agree that the symptoms of IUI and early menstruation are quite similar. One must know a slight difference, as it can be confusing sometimes. However, in my case, there were not very loud symptoms when I conceived.
