Artificial insemination is nothing unusual in the modern world. It has been developing the most active in the last decades. Thanks to this procedure, the couples that had been deemed to be childless now have high chances to feel the joy of parenthood. Nowadays, there is quite a vast number of artificial insemination methods.
One of the easiest methods is intrauterine insemination (IUI). It is an assisted reproductive technology (ART) when specially prepared sperm of a man is introduced to the uterus of a woman. This procedure may be conducted using both husband’s or donor’s sperm.

Artificial insemination is nothing unusual in the modern world. It has been developing the most active in the last decades. Thanks to this procedure, the couples that had been deemed to be childless now have high chances to feel the joy of parenthood. Nowadays, there is quite a vast number of artificial insemination methods.
One of the easiest methods is intrauterine insemination (IUI). It is an assisted reproductive technology (ART) when specially prepared sperm of a man is introduced to the uterus of a woman. This procedure may be conducted using both husband’s or donor’s sperm.
IVF treatment and Indications for IUI
The most common pathologies of the male reproductive system are as follows:
- sperm subfertility, i.e. the potential for insemination is decreased;
- ejaculation disorder – in this case, the biological material (sperm) is collected and conserved.
In order to assess the man’s ability for fertilization, doctors prescribe semen analysis. If its results show any deviations, at first, it is recommended to take the semen analysis one more time, no earlier than in 2 weeks.
The following disorders may be detected using semen analysis:
- asthenozoospermia, i.e. sufficient decrease in the mobility of the spermatozoa (less than 25%);
- oligozoospermia, i.e. decrease in spermatozoa concentration ( less than 15 mil in 1 ml);
- teratozoospermia, i.e. increase in the numer of sperm pathologies (more than 70%)
- oligoasthenoteratozoospermia, i.e. presence of all the abovementioned abnormalities;
- azoospermia, i.e. absence of spermatozoa in ejaculate;
- aspermia, i.e. absence of ejaculate
If a man is diagnosed with one of the pathological conditions that prevent the IUI, when infertility in man is impossible to treat or there is a risk that the child will inherit the genetical diseases, then the couple is offered to use donor material.
Intraperitoneal insemination and intrauterine insemination: differences
In intraperitoneal insemination, the sperm is administered in the area of the lesser pelvis called Douglas space. Due to such insemination, the spermatozoon can faster reach an egg, and the pregnancy is more likely.
In the ordinary intrauterine insemination, the sperm is administered directly in a woman’s vagina.
IUI procedure: time, IUI process
IUI is a relatively simple and minimally invasive fertility treatment that aims to increase the chances of fertilization by placing sperm directly into a woman’s uterus. Here’s a general overview of how it works:
- Ovulation stimulation (optional). In some cases, fertility drugs may be used to stimulate the ovaries and encourage the development of multiple mature follicles.
- Sperm preparation. On the day of the procedure, a sample of sperm is collected from the male partner or also you can use donor sperm. The sperm is then “washed” and concentrated in the laboratory to select the healthiest and most motile sperm.
- Catheter insertion. The woman lies on an examination table, similar to a pelvic exam. A speculum is inserted into the vagina to visualize the cervix. A thin, flexible catheter is then inserted through the cervix and into the uterus.
- Sperm injection. The prepared sperm sample is slowly injected through the catheter and into the uterus.
- Catheter removal. The catheter is carefully removed and the speculum is removed.
- Rest period: The woman may be advised to rest for a short time after the procedure.
- Follow-up. Approximately two weeks after the IUI, a pregnancy test is performed to determine if the procedure was successful.
IUI success rates
The chances of becoming pregnant after artificial insemination depend on a number of factors, including woman’s age, infertility duration, sperm quality and characteristics, examination results, and the number of the previous IUI attempts.
The chances of getting pregnant with IUI are about 15%. Doctors recommend the patients, who didn’t become pregnant with IUI procedure, to resort to IVF (in vitro fertilization).
IUI success tips
- Understanding your ovulation cycle is important. Monitoring your ovulation through methods such as basal body temperature (BBT) tracking, ovulation predictor kits (OPKs), or blood tests can help you determine the best time to inseminate. Timing IUI around ovulation increases the chances of success.
- Follow your doctor’s instructions carefully. Make sure you’re following all of your fertility specialist’s instructions, especially regarding any medications or hormonal treatments. Medications to stimulate ovulation should be taken exactly as prescribed to optimize egg production.
- Maintaining a healthy lifestyle can greatly influence the success of IUI. This includes eating a balanced diet, exercising regularly, avoiding smoking and excessive alcohol consumption, and managing stress. These factors can all contribute to a healthy reproductive system and better fertility outcomes.
- If male infertility is a factor, it’s important to focus on improving sperm quality. Sperm should be well prepared prior to insemination to ensure higher motility and better chances of reaching and fertilizing the egg. Your fertility clinic will treat the sperm before insemination to improve its quality, but it’s also helpful to avoid factors that can negatively affect sperm, such as excessive heat, alcohol or smoking.
- Maintain a positive mental attitude. Fertility treatments can be emotionally and physically stressful. Try to remain positive and patient. Some couples may need multiple IUI cycles to achieve success, and each cycle provides valuable information for adjusting treatment as needed. Practicing relaxation techniques such as meditation or yoga can help manage the stress that often accompanies fertility treatments.
How many cycles of IUI do you try before IVF?
The number of IUI cycles attempted before moving on to IVF varies depending on individual circumstances and clinic protocols. However, a common approach is to try 3 to 6 cycles of IUI.
Here’s a breakdown of the factors that influence this decision:
- Success rates: Success rates for IUI are generally lower than for IVF. After a few unsuccessful cycles, the cumulative chance of pregnancy may plateau, making IVF a more effective option.
- Age: For women over 35, and especially those over 40, time is of the essence. If IUI is not successful within a few cycles, IVF may be recommended earlier.
Underlying problems: If there are severe male factor infertility issues, blocked fallopian tubes, or other significant fertility problems, IVF may be considered as a first-line treatment.
Cost and Emotional Burden: IUI is less expensive and less invasive than IVF. However, repeated unsuccessful cycles can take an emotional toll. A discussion with your doctor can help determine when the emotional and financial burden of IUI outweighs the potential benefits.
Clinic protocol: Fertility clinics may have their own standard protocols regarding the number of IUI cycles recommended before moving on to IVF.
Pregnancy and IUI benefits
This insemination method is maximally similar to natural conception, as it closely mimics the process of sperm meeting the egg in the natural environment of the uterus. Intrauterine insemination (IUI) can be performed either in thenatural cycle, where the woman’s body is monitored for ovulation, or in astimulated cycle, where ovulation is induced using medications to increase the chances of success. The procedure involves minimal intervention into the woman’s body, making it less invasive than other fertility treatments like in-vitro fertilization (IVF).
IUI is a relatively quick and painless procedure, typically taking only a few minutes. During the process, the sperm is carefully treated with special solutions that help improve its quality and increase the chances of successful fertilization. This preparation ensures that only the healthiest sperm are used for insemination. Additionally, the procedure is highlyaffordablecompared to other more complex fertility treatments, making it an accessible option for many couples facing infertility. It’s a great first step in fertility treatment, particularly for those with unexplained infertility or mild male factor infertility, providing a less invasive and cost-effective solution to achieve pregnancy.
So, the pairs that have some problems with conception sometimes need minimum interventions to success with the desired pregnancy. IUI is not recommended to the severe diseases of fallopian tubes, women with moderate or severe endometriosis. To perform IUI, it is necessary that the woman ovulates (it may be stimulated), at least one of her tubes should be obstruction-free and the healthy sperm is also necessary. IUI is performed during ovulation. The price of IUI is probably that most effective and cost-efficient from all the types of insemination, but its efficiency is the lowest as well.
