Aside from a few variations, conventional IVF and mini IVF typically follow the same process.

The biggest difference between conventional IVF and mini IVF is the amount of fertility medications used in the ovarian stimulation phase of the process and how that reduction in medication usage affects each patient's results.

Reciprocal IVF is a unique process that involves biological participation from both partners, and "natural" IVF involves no stimulation medications. More on these treatment types below.

The classic approach to in vitro fertilization (IVF) is to 'feed' all of the follicles in your ovaries so the eggs inside can grow at the same time, resulting in multiple mature eggs. This is accomplished with high-dose fertility medications that stimulate follicular development.

Note: The majority of fertility patients need high-dose medications to be successful.

Conventional IVF has the highest success rate out of the three variations, but is also the most expensive and requires the most time and effort. You will need to make multiple visits to your fertility clinic for frequent blood tests and ultrasound monitoring.

Reciprocal IVF (RIVF) is a variation on conventional IVF treatment for same-sex female couples (or a cis woman and trans man) who wish to share in the biological process of having a baby together.

In an RIVF cycle (also sometimes referred to as partner-assisted IVF or co-IVF), oocytes (eggs) from one partner are retrieved and fertilized with donor sperm to create embryos. These embryos can subsequently be transferred into the uterus of the other partner.

This allows both partners to personally participate in the same pregnancy, since one partner supplies the eggs to create the embryos, and the other partner carries the resulting pregnancy.

With mini IVF, the goal is to use a less intense treatment protocol (with low-dose fertility medications) in order to focus on the growth of just a few eggs. This can be beneficial for those with low ovarian reserve, sensitivity to stimulation medications, or a desire to only create a small number of embryos.

However, the success rates for natural IVF are significantly lower than with conventional or mini IVF. This method also still requires multiple office visits for monitoring.

While there are some exceptions, a mini IVF cycle usually produces fewer eggs than a full stimulation (conventional) IVF cycle. One mini IVF cycle typically results in the retrieval of only 1–3 eggs, whereas conventional eIVF aims to retrieve as many eggs as possible.

The number of embryos that develop from the retrieved eggs will vary.

While some doctors and clinics who promote "natural" or mini IVF protocols claim that lower doses of medication will result in higher quality eggs, there is no scientific evidence to support this claim. 

In a 2016 study published in the Journal of Fertility and Sterility, researchers concluded that embryos produced in "natural" (unmedicated) IVF cycles were not, in fact, of a higher quality than those produced through conventional IVF.

What they found was that the ratio of normal to abnormal embryos was essentially the same in both types of cycles, and there was no evidence that unmedicated IVF improved egg quality.

If you have lower anti-Müllerian hormone (AMH) levels, have undergone conventional IVF cycles without good results, feel like your treatment protocol isn't being adjusted to fit your needs, or are frustrated by a lack of explanation from your doctor about why IVF isn't working for you, mini IVF may be worth exploring.

Individuals and couples who want to reduce the costs associated with IVF, avoid higher doses of medication, or who are looking to reduce the time commitment associated with conventional IVF treatment may also want to consider a minimal stimulation cycle.

When there are only a few eggs in the ovaries to begin with, either due to age or diminished ovarian reserve, the full dose of fertility medications is not going to produce the high number of eggs (10-15) we need through a conventional IVF cycle.

These patients may do just as well (or better) with mini IVF, as it only involves a small amount of medication and typically leads to the development and maturation of around 1-3 eggs.

One big difference between mini and conventional IVF is the number of embryos that are left over at the end of a cycle. Keep in mind that if your goal is to have more than one child, you'll want to end up with multiple embryos.

Conventional (high-dose) IVF is more likely to produce additional embryos, increasing your chance of having embryos to freeze for future use, while mini IVF frequently only results in one embryo per cycle.

Another medical reason for considering mini IVF is that some patients cannot tolerate the amount of fertility medications used in conventional IVF treatment, with some being prone to develop ovarian hyperstimulation syndrome (OHSS). 

What do the experts say?

According to the American Society for Reproductive Medicine (ASRM):

"In patients who are classified as poor responders and pursuing IVF, strong consideration should be given to a mild ovarian-stimulation protocol (low-dose gonadotropins with or without oral agents) due to lower costs and comparable low pregnancy rates compared with traditional IVF stimulation protocols."

Note: The following information reflects self-pay pricing. If you have insurance coverage or other financial assistance for fertility treatment, these costs may be considerably lower.

Conventional IVF treatment can cost anywhere from $15,000 to $30,000+ per cycle, with medications accounting for up to 35% of the total cost. These medications can range from $50 or less for Clomid to $1,000 to $2,000 for injectable hormones.

Since mini IVF treatment involves fewer medications, the average cost per cycle is usually lower. That said, it's important to understand that the exact cost of mini IVF can vary widely based on several factors, and it may not be the most cost-effective option for you.

As you explore your options, keep the following factors in mind:

• Clinic costs: Every practice has a different pricing structure, but the amount you pay to your fertility clinic likely won't change much with mini IVF, as all the same medical procedures are being performed. If you are paying out of pocket and utilizing one of your clinic’s self-pay pricing plans, note that the cost of medication is typically not included.
• Your location: Costs can vary depending on where you live.
• Medications: Because you'll be using fewer medications, the amount you pay to a pharmacy will generally be lower. Medication type and dosage still impact overall cost.
• Add-ons: If you need additional procedures (such as ICSI, assisted hatching, or preimplantation genetic testing), this will increase the cost of treatment.
• Number of cycles: Low-stimulation IVF can require more cycles to achieve a successful pregnancy, meaning you may need to undergo multiple mini IVF cycles in order to get a similar amount of embryos to conventional IVF or be able to cryopreserve (freeze) embryos for future use.

A typical mini IVF cycle lasts around two weeks and follows the same general structure as a conventional IVF cycle. While your personal protocol and timeline may look different, below is an idea of what you can expect:

Oral medications are taken to stimulate the ovaries to produce eggs. Low-dose injectable medications may then be added in to promote egg growth and maturation. Progress is monitored through blood work and ultrasounds over 2-3 visits to your fertility clinic.

At the right stage of development, you'll be instructed to take an injection called a "trigger" shot to promote egg maturity, and an egg retrieval is scheduled for 36 hours later.

A minor, outpatient surgical procedure called an egg retrieval is performed to remove the mature eggs from the ovarian follicles (the tiny fluid-filled sacs that contain the eggs). Egg retrievals are performed under anesthesia to ensure you remain 100% comfortable. 

Any mature eggs that were retrieved during your procedure are then fertilized in the IVF lab in one of two ways: 1) Allowing sperm and eggs to "mingle" together in a petri dish or 2) through a process called intracytoplasmic sperm injection
