Ovodonation and Mini-Ovo

Our donors are personally selected by our donation team by meeting them, interviewing them and checking all the exhaustive analytical and genetic tests they have to pass. It allows us to match each recipient with the perfect donor, since we are the ones who do it personally.

Because although the number of eggs obtained is somewhat lower, the quality of the eggs is much better. Because we are committed to quality over quantity, because what we want is to get pregnant the first time with the best embryo from the best egg.

The operating room has an air conditioning system that we can control so that the temperature during the ovarian puncture is maintained at adequate values for the oocyte, as well as a positive pressure system.

Following European recommendations, the laboratories for semen treatment and embryo culture are physically separated. Better control, better conditions, better results.

The environment in which embryos grow is critical for good embryo quality. For this reason, we offer you the most advanced incubator that allows us not only to perfectly control the culture conditions, but also to observe the embryos during their development without the need to remove them from the incubator. These continuously stable conditions together with embryo morphokinetic information, allow us to select the best embryos with the highest probability of implantation and achieve pregnancy with an exceptional rate.

ERGO was the second clinic worldwide to be accredited to perform this technique. It consists of being able to know the chromosomal status of the embryos without the need to biopsy them, simply by analyzing the drop of culture in which they have been developing.

This is a specific embryo culture medium for the time of transfer. As its name suggests, it acts as a “glue” between the embryo and the endometrium thanks to the hyaluronic acid molecule that is part of its composition. Natural, physiological and with very good results especially in patients with implantation failure.

Our laboratory team is composed exclusively of embryologists with many years of experience and continuous and specific training. They also hold the European Senior Embryology certification ESHRE (highest qualification worldwide) and the certification as Clinical Embryologists at the national level.

Our experience allows us to objectively evaluate the quality of the embryos, and to know which embryos are really of high quality. Therefore, we clearly assign quality A or B to those embryos with a probability of implantation higher than 70%. If they do not meet the quality standards to achieve that ratio, they will not be transferred.

Our gynecology team together with the donation team ensure that the ovarian stimulation of the donor begins when the recipient patient must begin her endometrial preparation; this is key, since at the ERGO Clinic we perform the oocyte donation cycles with fresh eggs. It is as simple as administering birth control pills to the donor for a few days so that these dates coincide. In this easy way we achieve that on the day of the ovarian puncture of the donor, the recipient is ready to receive the embryo or embryos in fresh embryos between 2 and 5 days later.

The donor undergoes ovarian stimulation treatment to achieve the growth of several follicles within which the eggs grow and mature. Once they are the right size, a follicular puncture is performed under mild sedation for the extraction of the oocytes contained inside.

On the day of the donor puncture, the recipient’s partner provides a semen sample that will be treated and prepared to fertilize the donor’s oocytes. This sample can be obtained comfortably at the Clinic since we have a space dedicated exclusively for this purpose. If donor sperm is also required, the andrology laboratory team will have it ready for the same day.

A complementary technique called Embrace allows us to confirm the absence of genetic chromosomal alterations in embryos without the need for biopsy, simply by analyzing the culture drop where they have been developing.

The uterus of the recipient woman is prepared with a treatment with estradiol (pills or patches), which makes the endometrium (inner mucous layer of the uterus) grow. Through a series of transvaginal ultrasounds and blood tests, it is checked every few days that the endometrium is growing in size and is ready for embryo transfer.

From the day the oocytes are inseminated, the embryologists will contact the recipient patient and her partner by telephone to keep them informed of the evolution of their embryos. The date of transfer is individualized to each case, since biologically they can be transferred from day 2 of development to day 6. The date and time of the transfer is agreed between the patients and the medical team of the clinic in order to adjust it to the best conditions for the patients and the embryos.

This is a specific embryo culture medium for the time of transfer. As its name suggests, it acts as a “glue” between the embryo and the endometrium thanks to the hyaluronic acid molecule that is part of its composition. Natural, physiological and with very good results especially in patients with implantation failure.

If the test tells us that you are pregnant… Congratulations! The whole team will share this great moment with you, but we will also give you the basic instructions that you must follow from then on, such as medication guidelines, precautions in your daily life and, above all, we will give you the appointment for the ultrasound examination to confirm clinical pregnancy. It will be approximately 3 weeks after the result of the test, since it is at that time when you can visualize with guarantees the fetal heartbeat of your little one.

If, on the other hand, the result is not what we expected, don’t worry, we will not leave you alone in this hard moment. We will give you an appointment with the medical team for the date you want, and there we will solve all the doubts you may have, we will analyze with you what could have happened and above all what options there are to help you achieve your dream.

All embryos that have not been transferred to the patient’s uterus and that are of good quality should be vitrified. This is stipulated by the law on assisted reproduction. It is a process routinely performed in the ERGO Clinic’s embryology laboratory and survival rates exceed 99%.

Our donation team personally selects each donor applying the strictest controls to guarantee the greatest safety in this process and the greatest phenotypic similarity with the recipient. We must always thank our donor group for their generosity, they are the ones that allow us to offer these treatments with the best guarantees and without waiting lists.

Thanks to this pioneering technique for which ERGO has obtained authorization, we can confirm that the embryo has no genetic alterations (specifically chromosomal alterations, both numerical and structural) involved in implantation failure, repeated miscarriages or pathologies such as Down Syndrome, among others. All this, without the need to biopsy the embryos, simply by analyzing the culture drop where they have been developing (you can find more information in the EMBRACE section of our website).

We know how important it is for you to be sure that everything will go well. At ERGO we have the option of guaranteeing a number of top quality embryos on day 3 or day 5. There is also the possibility of assigning a complete donor cycle to a single recipient couple; in this case we guarantee that the recipient woman will receive a minimum of 7 mature eggs from the donor. This, together with the totally controlled culture of the embryos, allows us to achieve the best results.

This additional test is performed on both the egg donor and the recipient’s partner, reducing the risk of the future child suffering from more than 600 known genetic diseases.

In a period of one month, you can have your treatment done. You will always have the support of the donation team with personalized attention, which will accompany you throughout the process to help you in everything you need.
