IN VITRO FERTILIZATION (IVF)
What is In vitro Fertilization?
In Vitro Fertilization (IVF) is a laboratory technique that allows for a woman’s eggs to be fertilized outside of her body. In order to perform this technique, the eggs and the sperm have to be retrieved. IVF can be done using the patients’ gametes (sperm and egg) or donated ones. This means, there are four different treatment options using this technique:
IVF using the patients’ own gametes
IVF using the patient’s own eggs and donor sperm
IVF using donor eggs and the patient’s sperm. This treatment is known as the Egg Donation Treatment
IVF with donor sperm and eggs.
Treatment indications for IVF and ICSI are:
Stages of the IVF-ICSI Process
Hormones are administered by subcutaneous injection (which the patient can administer herself) to stimulate the ovaries. The medication helps increase the number of follicles that mature during the cycle. Serial ultrasound checks will be made in order to adjust the necessary dose of medication and program the egg retrieval.
Egg retrieval is a simple process that is performed under transvaginal ultrasound guidance and sedation. The process takes about 15-20 minutes. After the procedure, the patient wakes up easily without secondary effects.
Eggs can be fertilized in 2 different ways:
- Conventional IVF: the eggs and the sperm are put in a culture plate and spontaneous fertilization takes place.
- ICSI or Sperm microinjection: This is a technique where the biologist selects a spermatozoon and it is injected into an egg.
Embryo transfer takes place 2 to 5 days after egg retrieval. The number of embryos transferred (1, 2 or 3 embryos) will be decided according to the embryo quality and the characteristics of each couple. The decision on how many embryos to transfer will be reached by consensus from the patients, the biologists and the doctor.
Guided by abdominal ultrasound, the embryos are transferred to the fundus of the uterus. The procedure is quick and painless and no sedation is required.
The patient will undergo a pregnancy test about 15 days after the embryo transfer.
At ProcreaTec our goal is that our patients have a healthy baby at home in the shortest time. For this purpose we guarantee:

Treatment options for women with a low ovarian reserve
The protocol for In vitro Fertilization using the natural cycle allows the retrieval of the egg that the woman produces spontaneously during her menstrual cycle.
It is recommended to women who do not want to undergo conventional hormone treatment or for those who did not respond to conventional stimulation.
The development of the follicle is monitored with ultrasound scans. The advantage of these cycles is that there are next to no medication costs and it is much easier for the patient.
The protocol for Mild Stimulation consists of using the minimal amount of medication in order to retrieve the egg. It is recommended for patients who do not want to undergo a conventional hormone treatment or for women who were not responsive to previous treatments
Inquire about your case and we will send you an estimate of the costs based on your needs.
The protocol for Egg Banking allows women with a low ovarian reserve to accumulate a greater number of eggs by undergoing various stimulations
Accumulating eggs increases the possibilities of being able to transfer an embryo.
It is recommended for patients with a low ovarian reserve who would like to maximize the possibilities of getting to the embryo transfer or for those women who want their embryos to undergo genetic diagnosis.
Frequent Questions on In vitro Fertilization
The main advantage of undergoing In vitro Fertilization at ProcreaTec is our excellent pregnancy rate, which is currently 45.2% for patients using their own eggs and we have a 64% success rate for treatments with donor eggs. We use cutting-edge technology with all the advances in Assisted Reproduction and we have the best specialized doctors.
Our laboratory pioneered the blastocyst culture technique used to increase the chances of pregnancy.
Thanks to our efforts and professionalism we have an international and a European Quality Control certifications: ISO-9001/2015 and UNE 179007.

Yes, you may continue working and stay in your country of residence during the stimulation, with no need to travel until just before the egg retrieval.
The stimulation of an IVF cycle last between 10 and 12 days. On the same day of the egg retrieval, the eggs will be fertilized. The embryo will be transferred on the third or the fifth day.
Our patient care representatives can give you hotel suggestions and provide information on how to get to the clinic.
In a 28-day cycle, it is estimated that ovulation takes place on day 14. About 24 hours after, the woman’s temperature goes up and that is the way to know if the woman has ovulated. At present, pharmacies sell ovulation kits so the woman can test and see if she is going to ovulate and thus have sex to coincide with her most fertile moment.
In our assisted reproduction clinic, we can monitor the ovulation with ultrasound scans on different days of the cycle and blood will be drawn to test hormone levels to make sure that the necessary hormone levels rise for ovulation and, thus, help natural conception.
Most patients with a regular cycle (26-35 days) ovulate every month. To have regular cycles, hormones that make the endometrium grow and mature are synchronized to achieve ovulation in the middle of they cycle.
For patients with longer or irregular cycles (30-90 days), the body is creating hormones to make the endometrium grow. If there is no ovulation, the endometrium spontaneously sheds. This process makes for long and/or irregular cycles and sometimes, in these situations, there is no ovulation.
The spermatozoon is the male gamete and it defines the sex of the future baby. It is a germinal cell composed by a head, a midpiece and a tail. Any anomaly of any of the parts imply that there is a decrease in the probability that this spermatozoon will fertilize the egg.
A sperm analysis evaluates the morphology, the mobility and the concentration of sperm per milliliter. The morphology or shape of the sperm should be oval and smooth, the tail should be three times as long as the head and present a correct insertion into the head. The mobility is defined by the speed at which the sperm advances (micrometers per second) following a lineal path. All these parameters should be within the normal limits established by the World Health Organization in 2010 in order to have the best chances of success.
