The MiniFIV treatment is an assisted reproduction treatment similar to the IVF/ICSI treatment. The fundamental difference is in the stimulation phase. The goal is to limit the number of ovules by a milder ovarian stimulation; therefore, the patient needs to administer much less medication, reducing the hormonal burden of treatment.

Who is this treatment recommended for?

  • Women under 35 years of age, with good ovarian reserve and good prognosis.
  • History of excessive ovarian responses
  • Patients at risk of ovarian hyperstimulation


  • Less amount of medication to administer
  • Fewer visits to the clinic for ultrasound controls during stimulation
  • Less discomfort and side effects since the stimulation is smoother


  • A smaller number of oocytes is obtained. It could reduce the success of the cycle and therefore the pregnancy rate.
  • The possibility of having a large number of good quality embryos that can be cryopreserved in the future is reduced.

How is the process of in vitro fertilization in the MiniFiv technique?

As we have said, the process of in vitro fertilization in MiniFiv is identical to conventional IVF, only the dose of hormones administered in ovarian stimulation varies. So that you can better understand all the steps, we will explain them to you next.

In vitro fertilization is carried out in several phases but it is completely outpatient. That is to say, that the treatment will be carried out entirely in the consultation and you will not have to stay entered. At approximately two hours after the intervention, you can go home quietly.

Surely you are interested to know where you could start in the event you opt for In vitro fertilization. We want to explain the steps of the process in order for you to be familiar with the informative title and in any case we will be at your side to guide you at every stage and to dispel any doubt however small.

The first step in this treatment would be to introduce hormones to enhance the development of your eggs. During this first phase of treatment, you are monitored by ultrasound scans and blood tests to check hormone levels. Once the test results give us the green light, it will be time to proceed to the extraction of the eggs.

The puncture of the egg is performed through ultrasound  aspiration  to guide us  in the the egg selection. This process does not require anesthesia, but we will use a mild sedation, As we have said, it is completely outpatient. It is not painful though it can be somewhat uncomfortable. Once extracted, the eggs of the best quality are selected  and they are put together with the semen in the laboratory to obtain fertilization. If the quality of the sperm is low, ICSI technique is advisable.

If the fertilization is successful, the cell will begin splitting and form the first stages of an embryo. If necessary, the DNA of a single cell of an embryo can be verified through  PGD/PGS studies to rule out genetic abnormalities.

The transfer of embryos, that is the introduction into the uterus, usually takes place between day 3 or day 5 of embryo development. It is a process that consists of the introduction of a catheter containing the embryos into the vagina and then placing the embryos in the uterus. Pregnancy occurs when the embryo is implanted in the lining of the uterus and starts to develop.

In collaboration with your doctor, you will have to decide if you only want to transfer one embryo or two. Chances increase significantly with two embryos, but you will also have to take into account the chances of a multiple pregnancy. Currently and according to Spanish legislation, the implantation of more than 3 embryos is not allowed.

The current trend is to avoid transferring more than two embryos, and you should also be informed that thanks to recent advances in assisted reproduction, it is possible to be pregnant with the implantation of a single selected embryo (the best) in order to avoid a multiple pregnancy.

After the treatment, you should continue with hormone medication to assist in the implantation of the embryo. The hormone that will be used is called progesterone and its goal is to help thicken the lining of the uterus.

Approximately 12 to 14 days after the embryo transfer, you will have a blood test to confirm whether the treatment has been successful and if there is any pregnancy.

OR-Ovarian Rejuvenation

It is a revolutionary technique that involves the reactivation of stem cells and the remaining follicles in the ovary.

IA – Artificial Insemination

It is an assisted reproduction technique that will help you get pregnant easily and safely.

IVF – In vitro fertilization

It is the union of the ovum with the sperm in the laboratory, in order to obtain embryos already fertilized to transfer to the maternal uterus and achieve a pregnancy.

Egg Donation

Fertility treatment that consists of performing an In Vitro Fertilization with anonymous donor eggs. If necessary, this egg is fertilized with semen from the partner or another donor.

Genetic diagnosis

It refers specifically to the technique used in the event that one or both parents have a genetic abnormality. The embryo is analyzed to determine if it carries the same genetic abnormality.

ROPA Method

It consists of an In Vitro Fertilization treatment shared between both women, that is, one woman is the donor of the egg, while the other woman is the pregnant woman of the embryo.
