IUI vs. IVF Explained: Which Fertility Path Fits Your Journey?

If you’ve been TTC (trying to conceive) for over a year, it’s time to start exploring your options. Fertility treatments like intrauterine insemination (IUI) and in vitro fertilization (IVF) can be the solution to your reproductive woes and increase your chances of conception. IUI vs. IVF: Which one is better for you?

In this blog, we shed some light on the differences between IUI vs. IVF and which one can be more effective for you.

What is IUI Treatment? The Step-By-Step IUI Process

Intrauterine insemination (IUI) is a highly affordable fertility treatment in which the sperm is placed directly in the uterus, bypassing the cervix and fallopian tubes. It is not as invasive as other treatments like IVF and can help familiarize patients with the ins and outs of fertility treatment.

Preliminary Testing

Your clinic will schedule blood tests and ultrasounds before your IUI procedure to monitor your hormone levels and the growth of your follicles and to track ovulation. The male partner’s semen may also be analyzed to check his sperm parameters.

Ovulation Induction (Optional)

The IUI process works with your body and its rhythms. It is timed around your menstrual cycle and takes place specifically during ovulation. If you ovulate irregularly or not at all, your IUI treatment will include a shot of hCG (human chorionic gonadotrophin), which is a hormone that triggers ovulation.

Cycles that require ovulation induction usually take longer. You will take medication for approximately 5 to 12 days until ovulation occurs.

Superovulation or Ovarian Stimulation (Optional)

Ovarian stimulation is a completely optional part of the IUI process. Your fertility specialist will discern whether you require it or not. Ovarian stimulation involves stimulating the ovaries into producing multiple mature eggs instead of a single one, which increases your chances of pregnancy.

If you take any fertility drugs alongside your IUI treatment, it is called a ‘stimulated cycle,’ while cycles that don’t require fertility medication are called natural or unstimulated cycles.

Semen Collection and Sperm Washing

Then, the male partner provides a semen sample. The sample is ‘washed,’ a technique that separates the sperm cells from the semen and removes dead or immotile sperm to prepare a concentrated sperm sample. Sperm washing ensures that only the best sperm remain, and this can increase the chances of conception.

Insemination Procedure

The insemination procedure usually takes place after your ovulation surge and can be done in-office. The embryologist first uses a speculum to locate your cervix. They then load a catheter with the concentrated sperm sample and carefully guide it to your uterus via your cervix. They deposit the sperm directly into your uterus, and the entire process takes just five to ten minutes! 

The entire process is painless, and anesthesia is not required. After the procedure, you will continue to lie down and rest for a short while and then go home. You can walk and carry on with your daily routine as normal. You can take a pregnancy test approximately 2 weeks after the procedure.

Who Is It For?

Intrauterine insemination is recommended to patients with the following fertility issues:

• Patients who have no female fertility issues can do IUI with donor sperm
• Men who have low sperm count or motility can do IUI as long as they have enough healthy sperm
• Women with cervical factor infertility or cervical mucus hostility
• Women with mild endometriosis
• Women with PCOS
• Serodiscordant couples are when one partner has HIV while the other is HIV-negative
• Men with erectile dysfunction, or inability to ejaculate
• Couples who find it difficult to have intercourse due to psychosexual problems, injuries, or disabilities

IUI is usually recommended to patients with unexplained infertility, as it is cheaper and less invasive than IVF. It is the best treatment for patients who have a semen allergy but no male or female factor infertility. In semidiscordant couples when the male partner has HIV, sperm washing can safely and effectively help the couple conceive an HIV-free child.

IUI is also preferred by certain patients, as they find the IVF process too invasive and intimidating. They may choose to undergo multiple IUI cycles instead of switching to IVF.

What Are the Disadvantages of IUI Treatment?

IUI can definitely be useful, but it has certain disadvantages and limitations too.

• IUI isn’t recommended to women who have blocked fallopian tubes or are missing one or both tubes
• It can be uncomfortable as the insertion of the catheter may feel similar to menstrual cramps
• In stimulated cycles, there is a very minimal risk of developing Ovarian Hyperstimulation Syndrome, a possibly dangerous condition
• Inserting the catheter may sometimes be difficult or painful, especially in patients that have a tilted cervix
• You may experience spotting or light bleeding for a few days after the treatment
• There is a rare risk of developing an infection due to the catheter insertion

Success Rates of IUI Treatment

IUI has lower success rates than IVF treatment, as most of the reproductive process still takes place inside the body. This procedure has a success rate of 10 to 20%, which is the same rate as natural conception. The success of the process also depends on the sperm count of the man.

Cost of IUI Treatment

A single cycle of IUI treatment is more affordable than an IVF cycle. The cost of treatment will increase if you require services such as ovarian stimulation, ovulation induction, donor sperm, or other additional procedures. Prices also depend on the location and reputation of the fertility clinic.

Since IUI has low success rates, you may need multiple cycles to achieve a successful pregnancy. This can increase the overall cost of IUI treatment.

What is IVF Treatment? The Step-By-Step IVF Process

In vitro fertilization is one of the most popular infertility treatments in India. It is one of the most effective treatments available today, with high success rates and safe treatment protocols. Unlike IUI, IVF can treat a wide range of infertility issues.

Since IVF treatment is more invasive and expensive, most people prefer to try IUI before they move on to IVF. For patients who experience multiple failed IUI attempts, IVF is the next best option.

IVF is not a new fertility treatment. Many people have healthy children with IVF treatment. Many children born via IVF do not have any long-term health issues and go on to successfully have children of their own.

Ovarian Stimulation

You are given fertility medication to stimulate the ovaries to produce multiple mature eggs.

Egg Retrieval

After the eggs mature, they’re surgically retrieved through a thin, ultrasound-guided needle. You will be sedated during this procedure.

Fertilization

The mature eggs are placed on a petri dish with the healthy sperm cells. Fertilization occurs naturally, or it may be induced through methods like ICSI.

Embryo Development

The fertilized embryos are monitored in a laboratory for several days until they grow to blastocysts.

Embryo Transfer

An embryologist selects the best embryo and carefully transfers it to the uterus of the female patient. The rest of the embryos can be frozen or discarded.

If the patient chooses to get genetic testing done, all embryos are tested and then frozen until the test results come out. The embryologist will then transfer the best frozen embryo to the patient’s uterus.

Who Is It For?

IVF treatment is a very flexible and versatile treatment, used to treat various fertility issues in the following situations:

• Patients with unexplained infertility
• Male factor infertility
• Failed IUI cycles
• Patients with severe endometriosis
• Women with PCOS
• Women with ovulation disorders
• Patients with recurrent pregnancy loss
• Patients with secondary infertility
• Women with blocked, damaged or missing fallopian tubes
• Women with structural defects (congenital abnormalities) of the uterus
• Patients with genetic diseases or disorders that could get passed on
• The patient’s ovaries do not respond to infertility medications

What Are the Disadvantages of IVF Treatment?

IVF has many advantages, but it has certain drawbacks as well.

• Patients have a risk of developing OHSS or Ovarian Hyperstimulation Syndrome, a condition where the ovaries swell and cause pain due to sensitivity to fertility drugs.
• IVF is also linked to a slightly higher risk of birth defects and congenital health issues
• If multiple embryos are transferred, there’s a risk of multiple pregnancy, which increases pregnancy complications and the risk of miscarriage

To prevent the risk of multiple pregnancy, most clinics today only transfer a single embryo at a time, with very few exceptions.

Success Rates of IVF Treatment

IVF has a success rate of 35 to 40%, and the cumulative success rate of 3 consecutive IVF cycles is 60 to 70% for women under 35. The success rate varies based on factors like the patient’s age, health, and fertility. Services like PGT testing can also raise the success rate by identifying euploid (chromosomally normal) embryos that are more likely to implant in the uterus.

Cost of IVF Treatment

While IUI is much cheaper, IVF can cost up to twice or thrice as much, depending on the add-on treatments, clinic location, specialist expertise, infrastructure used, etc. The cost of medication may be included in the price of treatment or quoted as a separate add-on. Make sure to ask your IVF specialist about the costs and price breakdown of the process.

IUI vs. IVF: Difference Between IUI and IVF Treatment

Concluding Thoughts

IUI might be the perfect choice if you’re dealing with mild infertility issues and want to choose an affordable treatment. It is suitable for those who cannot afford other fertility treatments or who do not want to undergo invasive procedures and hormonal medication.

IVF’s higher success rates can offer hope and convenience. IVF can be the better choice if you’re planning to have multiple children. You can create more than one healthy embryo in a single IVF cycle and freeze them for future use. If you want more children in the future, you can transfer embryos from the same cycle for future pregnancies!
