In vitro fertilisation is the ideal treatment for women or couples in whom infertility persists after earlier simpler treatments such as Intrauterine insemination and Ovulation induction.

What does it offer?


In Vitro Fertilisation creates embryos in the laboratory with an egg from the mother and sperm from the male. The embryos generated are finally transferred into the mother’s uterus, where a completely normal pregnancy develops.


Currently, and thanks to the freezing of embryos, pregnancy rates of frozen embryos that have not been transferred in an in vitro fertilisation process obtain identical gestation rates to fresh embryo transfer. This means that if there are more frozen embryos remaining after in vitro fertilisation, pregnancy rates are higher.

Who is it for?

Couples or women in whom inseminations have failed

Age-related infertility in women

Repeated miscarriages

Parents with genetic diseases

Blocked fallopian tubes

Women with ovulation failure

Diagnosed Polycystic Ovary Syndrome

Women with endometriosis

Males with few, poorly moving, or abnormally shaped sperm

Couples with infertility of unknown origin

Female couples


During this first visit Fertty’s medical team will evaluate your entire reproductive medical history and review all the tests performed or request new tests if they have not been previously ordered (FSH on the third day of the cycle, Anti-müllerian Hormone or Antral Follicle Count by ultrasound). All this will help them to be able to design an exclusive personalised treatment.



Normally women produce only one egg during a menstrual cycle. Fertty’s medical team will use injections to instruct your ovaries to produce several eggs. This process lasts between 8 and 11 days and during this process the Fertty’s team performs ultrasound controls and, sometimes, analytical controls of E2 or progesterone. Once the follicles have reached an adequate size, an injection of HCG will be used to mature the eggs and induce ovulation.



35 hours after the HCG, we performed the aspiration of the eggs from the ovaries. It involves making a small puncture through the vagina. The medical team performs an ultrasound in which a needle will have been attached to the ultrasound machine and, through this fine needle, all the eggs available in that cycle will be aspirated. At the same time you will be mildly sedated for your comfort. The process takes about 20 minutes.

At the same time the partner will give a fresh semen sample. If this is not possible, the sample of donated semen selected for the process will be checked again. Before leaving the centre, you will be informed of the number of eggs collected and you will be instructed to start taking the progesterone that prepares the uterus for gestation. The embryo transfer will take place 3 to 5 days later.



Fertty’s team of biologists unites the eggs with the sperm so that fertilisation can occur spontaneously. In cases where there are few sperm or fertilisation failure is suspected, a sperm is introduced into the egg. This process is called Intracytoplasmic Sperm Injection (ICSI).



For roughly five days our team of embryologists regularly monitors the embryos to ensure that they are developing properly and dividing properly. The speed of division, the number of cells and their symmetry allows our team to select the highest quality embryos so that pregnancy can occur. Couples with genetic diseases, repeated miscarriages or age-related infertility may consider genetic diagnosis of embryos to select the healthiest embryo.



Three to five days after the puncture, the embryos are transferred into the mother’s uterus. This simple procedure is performed inside the laboratory, using a catheter to insert them through the cervix. This technique does not cause any pain and does not require anaesthesia, so the woman can leave the clinic within a few minutes and go about her normal life from the next day onwards. Pregnancy takes place if the embryo engages in the endometrium. The embryos that have not been transferred are frozen to allow for future implantation.



To help implantation occur, you will continue to take the progesterone for a further two weeks and a few days after the embryo transfer we will perform a blood pregnancy test. Once pregnancy is confirmed, you will continue to take progesterone for two weeks until your gynaecological team confirms the pregnancy by ultrasound. If the pregnancy has not been confirmed, you can decide with your gynaecologist to start a frozen embryo transfer or repeat a new cycle of In Vitro Fertilisation.

In Vitro Fertilisation is the most effective technique to obtain a baby.
During the phase of Embryonic Development, the Fertty team of biologists will inform you day by day of its evolution and care.
