What are the requirements for intrauterine artificial insemination?

Last Update: 03/18/2022

Intrauterine artificial insemination (AI) is a low-complexity assisted reproduction technique. Due to its simplicity, AI is generally the first option to attempt a pregnancy when a couple has mild fertility problems and goes to an assisted reproduction center.

However, the success rate of AI varies from 5.8% to 13.2% (delivery rate) depending on the woman's age. Therefore, it is very important to meet some requirements to guarantee the maximum chance of success.

Requirements for IUI

In order to perform an artificial insemination (AI) with the possibility of pregnancy, it is necessary that both the woman and the man (in the case of a male partner) meet a series of requirements. Among these prerequisites for AI are the following:

To check if the woman or couple has the necessary conditions to carry out artificial insemination, the specialist doctor will indicate the appropriate fertility tests that must be done previously.

In the event that these conditions are not met, it is best to go directly to the in vitro fertilization technique (IVF), since its success rate is much higher than that of AI.

Did you know that we can help you to choose a fertility clinic for your IUI cycle? All you have to do is get your Fertility Report now. It is an easy-to-use tool that is capable of filtering the best clinics and tailor an individual report exclusively for you with useful tips that will help you make a well informed decision.

In the following, we will explain in more detail each of the main requirements mentioned for artificial insemination.

Tubal patency assessment

In AI, the union of the egg with the sperm, that is, fertilization occurs in the woman's fallopian tubes. This is why to perform an AI that offers chances of success, it is essential that the patient's tubes are permeable and functional (or, at least, one of them).

The egg is picked up by one of the fallopian tubes after ovulation, where it waits for a sperm to fertilize it. In an AI, the semen sample is deposited directly into the woman's uterus. However, the sperm must subsequently travel on their own to reach the egg in the fallopian tube. Therefore, if the fallopian tubes are blocked, the egg and sperm cannot meet and pregnancy will not occur.

For all these reasons, it is essential to check the patient's tubal patency as a requirement to perform an AI. This procedure can be performed with any of the following techniques:

This is a radiological study of the female reproductive system thanks to the injection of a contrast liquid through the vagina.
consists of the introduction of a saline fluid or a foamy gel through the cervix that allows observation of the uterus and tubes by ultrasound.

These tests, in addition, also provide information on possible uterine malformations that could hinder embryo implantation or the development of pregnancy.

Age and ovarian reserve

As explained above, the maximum age recommended for a woman to undergo IUI is 36 years. From this age on, the success rate starts diminishing dramatically due to a diminished ovarian reserve.

Moreover, regardless of age, all women have to undergo a series of blood tests to get their hormone levels checked, including an AMH test (anti-Müllerian hormone test).

This hormone study, together with a transvaginal ultrasound to perform an antral follicle count, will allow the gynecologist to assess the ovarian reserve and the function of the patient's menstrual cycle.

Sperm quality

Once the semen is deposited in the patient's uterus in an AI, the sperm must be able to reach the egg without any help. For this reason, it is essential that the man has good mobility and sperm concentration so that the AI ​​has a chance of success.

The main test in men that will determine if artificial insemination is possible is the REM seminogram (Motile Sperm Count). After processing the seminal sample, the REM obtained must be equal to or greater than 3 million spermatozoa in order to carry out the AI, that is, there must be at least 3 million spermatozoa that are moving well.

On the other hand, if the only requirement that is not met to perform AI refers to the quality of the sperm, the couple may choose to perform artificial insemination with donor sperm (AI with donor sperm) or go directly to IVF.

Cost of AI

Artificial insemination is one of the cheapest assisted reproduction treatments. Therefore, it is the most chosen option for a first attempt as long as the basic requirements of age, seminal quality, and tubal functionality are met.

The cost of AI varies depending on the assisted reproduction clinic chosen, but it usually ranges between 700-1,100€. If you have to resort to a sperm donor, as would be the case of single mothers by choice or female partners, the price of AI can be up to €1,700. This is due to the necessary financial compensation for the donor.

In other international countries like Spain, the price varies from €600 to €1,000. Learn more: Assisted Reproduction in Spain – Everything You Should Know.

FAQs from users

By Elena Santiago Romero M.D. (gynecologist).

The IAD only requires the medical participation of one of the women of the couple, so the other is not involved in the treatment itself. However, for legal purposes, if both want to be the future parents of the baby, both must always sign the informed consent.

Of course, if that is not their wish, only the signature of the woman performing the treatment will be required.

Is there any difference between the requirements to undergo artificial insemination by husband (AIH) and artificial insemination by donor (AID)?

By Mark P. Trolice M.D., F.A.C.O.G., F.A.C.S., F.A.C.E. (reproductive endocrinologist).

Intrauterine insemination (IUI) or artificial insemination (AIH) involves the placement of washed sperm into a woman’s uterine cavity using a small catheter during a minor office procedure while the woman is awake.

The sperm are processed in the laboratory to obtain the highest numbers of moving sperm in a small volume as well as enhancing their fertilization potential. The IUI catheter deposits the sperm at a location closer to the fallopian tubes in comparison to intercourse. Following the procedure, the woman can resume all normal activity including intercourse with her partner.

Prior to IUI with partner sperm (AIH) and IUI by donor sperm (AID), the evaluation consists of ensuring the woman ovulates, confirming the fallopian tube(s) is/are open, and the sperm analysis is adequate for IUI. All women desiring pregnancy should undergo prenatal bloodwork including proper blood count, thyroid function, vitamin D level, immunity to the German measles (rubella virus) and chicken pox (varicela virus) as well as an updated Pap smear.

Additional recommendations for women desiring pregnancy with donor sperm include the same infectious disease testing as the donor including cytomegalovirus (CMV) antibody testing. If the woman tests negative for CMV then she needs to select a sperm donor who is also CMV negative to avoid the low but potential risk of infection to the baby. We also advise a psychological counseling session as a consent and for education.

Is there any special requirement for a single woman to undergo IUI?

By Zaira Salvador B.Sc., M.Sc. (embryologist).

No, a single woman who wishes to become a single mother through AID must meet the requirements already listed above: to have a normal ovarian reserve and tubal patency.

Since donor sperm is used, sperm quality will be excellent and comply with the minimum requirements to being used for an IUI.

Who can use artificial insemination?

By Zaira Salvador B.Sc., M.Sc. (embryologist).

Patients who turn to artificial insemination to achieve a pregnancy are those with mild infertility issues, including:

Moreover, it is the option of choice for single women and lesbian couples, as long as they meet the requirements explained throughout this article.

As already explained, a woman must have a good egg count for AI to be successful. To learn more about the importance of egg quality and quantity, see also: How Many Eggs Does a Woman Have? – Your Egg Count by Age.

As regards sperm quality, it can be assessed with a basic semen analysis. You can get the details of this infertility test in the following post: What Is a Semen Analysis Report? – Purpose, Preparation & Cost.
