In Vitro Fertilisation (IVF) | Eva Clinics In Vitro Fertilisation (IVF) | Eva Clinics




Eva Clinics put at your disposal not only the best experts, but also the most complete and innovative treatments such as In Vitro Fertilisation.


In Vitro Fertilisation is a treatment that can help you to get pregnant in a simple and safe way. Many women have already been successful in become mothers thanks to this technique, and you can be the next one. IVF is a very efficient treatment that consists in connecting sperm and eggs in the laboratory using the advanced IVF/ICSI technique in order to create embryos  of better quality to place them into the uterus through a simple technique.

It is different from other treatments because the egg fertilisation process is developed in the laboratory and not into female reproduction system, like happened in the conventional gestation process.

Eva Clinics have developed The Pregnancy Success Study to establish the expected success percentage of the treatment for your concrete case. It is totally free and we will previously deliver it to you before starting the treatment in order to let you aware of the possibilities you have to achieve a successful pregnancy in every cycle.


Intracytoplasmic sperm microinjection, also known as ICSI, is a new type of IVF and consists in participating even more actively in the fertilisation process. To realize ICSI, the best sperm is chosen to be inserted it through microinjection into the inner part of the egg cytoplasm. With ICSI, the insemination is much more direct, so the success percentage of pregnancy is increased.


In Vitro Fertilisation is an alternative treatment to  other fertilisation treatments  which have previously failed,  and in patients with disorders such as:

  • Endometriosis
  • Absence or damage of fallopian tubes
  • Polycystic ovary (severe disorder of ovulation process)


In Vitro Fertilisation treatment is longer than other fertility treatments. It consists of five phases:


In the natural process of the feminine menstrual cycle a woman releases one follicle which contains an egg. With medication we try to stimulate and control the ovulation.

1 ovarian stimulation


To control the number of the ovarian follicles created, we will keep monitoring the ovarian stimulation, by doing an ultrasound scan and a regular hormones analysis. When the ovarian follicles and the oocytes reach an appropriate number and size, we provide you the medication which induces the maturation of these oocytes.

2 follicular puncture

36 hours are required from the medication to the planned puncture which is carried out in the surgery under sedation so you will not have any discomfort during the process.

The extraction is approximately 10 to 15 minutes in which a detailed  ultrasound  is conducted to visualize the vagine and extract all the follicles inside which are the oocytes. Practically there is no risk of suffering disorder during this process.


Once the oocytes have been removed through the puncture we proceed to the oocytes’ insemination with your partner’s sperm in the laboratory with the help of a pipette. The next day we check if the union has given rise to the zygote.

3 embryo culture and fertilisation


Embryo transfer is the last and decisive step of the process to obtain your pregnancy by In Vitro Fertilisation. It’s a crucial phase of the treatment that takes place approximately 72 hours after the follicular puncture. Up to a maximum of two embryos are placed into the uterine cavity. The process is very simple even if the puncture is performed in the operating room.. Embryos are deposited in the uterus through a thin catheter which is made with a very adaptable material in order not to damage the walls of the uterine cavity and there is no need to be under sedation because it is a painless process.

4 embryo transfer

After the embryo transfer you need to rest approximately half an hour. Then you can return to normal activities obviously always in moderation.

Surplus embryos of the process will be frozen to avoid repeating the ovarian stimulation process and  also the follicular puncture, just in case that you don’t get pregnant in the first cycle during the  In vitro fertilisation.


Approximately two weeks after the embryo transfer, a pregnancy text is performed and two options are taken in consideration which are the following:

OPTION 1. You get pregnant:

In Vitro Fertilisation treatment has been successfully completed. Starting from this moment you can be discharged and kept under gynaecological supervision by your usual gynaecologist or by Eva Clinics specialized gynaecologist, the choice is yours.

OPTION 2. You don’t get pregnant:

When the cycle doesn’t end with  a pregnancy, the most important thing is not lose hope and keep calm. The fact that you don’t get pregnant during the first In Vitro fertilisation cycle doesn’t mean that you can’t get pregnant during the subsequent cycles. In light of this, possibility there are two options:

a. If you have frozen embryos we can make a Frozen embryo transfer, meaning, embryos which have been cryopreserved are transferred to the uterus like in the first In Vitro fertilisation cycle. It is also good to mention that preparing the uterus to receive a frozen embryos transfer is much simpler because repeating the ovarian stimulation and the follicular puncture process will be not necessary.

b. If you don’t have frozen embryos we go ahead and try with a second cycle, starting In Vitro Fertilisation process again from zero.

How many cycles can you undergo?

It is advisable to receive up to three IVF cycles. Our Eva will guide you in the most appropriate way to perform the treatment. We will assess how the first cycle went and if the assessment is correct we advise you to repeat the In Vitro Fertilisation Cycle.


Eva Clinics want to offer you the most competitive price on the market. In Vitro Fertilisation costs will vary depending on the cycle.

Icsi not included mandatory. Your medical consultation is always free.
