IVF with donor eggs, also known as egg donation, is a reproductive option that offers high pregnancy rates by using eggs from young, healthy women. This is why it is considered a fertility treatment with few risks for the recipient since she will not undergo ovarian puncture.
Nevertheless, it is true that IVF with ovodonation involves a great deal of grief for the patients as they are unable to contribute their genetic load. This can lead to various psychological problems in women.
Provided bellow is an index with the 7 points we are going to expand on in this article.
Risks in endometrial preparation
Ovodonation is a fertility treatment indicated for women who, for various reasons, cannot use their own eggs to produce a healthy, evolving embryo. This reproductive technique would be indicated in patients with advanced age, occult ovarian failure, genetic anomalies, repeated miscarriages, menopause, etc.
Therefore, the first step for the recipient in an oocyte donation is the preparation of her endometrium. It is essential that the endometrium be thick and trilaminar in an appearance on the day of transfer. This will help the embryo to implant and the pregnancy to take place. If on the day of the embryo transfer, the endometrium is too thin, the embryo will not be able to attach to it.
The preparation of the endometrium can be done naturally, although most commonly hormonal medication is administered. The recipient will take estrogen and progesterone until the endometrium is seen ultrasonographically with the desired thickness and appearance.
When hormones are administered exogenously, the patient may experience some discomfort such as headache, nausea, breast tenderness, fatigue, etc. However, these symptoms are usually mild and disappear after a short time in women.

What are the risks of the transfer?
Embryo transfer is a step of IVF and consists of depositing the embryos in the uterus by means of a fine cannula. This procedure is performed in an ultrasound-guided manner and is not very complex. This is why the risks associated with embryo transfer are low.
Nevertheless, as in any other procedure, it is possible to associate some risk factors with the transfer. For example, there is a possibility that the embryo may become attached to the transfer cannula. This is easy to detect since the cannula is always checked after insertion into the uterus. In this way, if the embryo had remained adhered to the cannula, it would be observed in the laboratory.
Another incidence associated with embryo transfer is that the woman may have a small amount of bleeding after the procedure or difficulty for the entrance of the cannula due to a narrow cervix.
Rarely, the woman feels pain during embryo transfer. Infections are also rare after this procedure.

Risks of IVF pregnancy with donor eggs
Some people believe that there are greater risks in egg donation pregnancies than when using their own eggs; while others think the opposite since eggs from young girls are used.
The truth is that the risks in pregnancy will depend on the situation of each woman and her characteristics. Most of the patients who resort to ovodonation are of advanced age. This is why the dangers of pregnancy increase, regardless of the origin of the eggs. As a woman's age increases, there are greater risks in pregnancy. Some of them are discussed below:
- Gestational diabetes
- Arterial hypertension or preeclampsia.
- Premature delivery
- Low birth weight.
In addition, if a multiple pregnancy were to occur in older women, the risk of suffering these complications would also increase. Therefore, it is always recommended to transfer a single embryo.
However, thanks to ovodonation in older women, the probability of miscarriage is reduced.
Genetic mourning of ovodonation
One of the things that most people think about when the recommended reproductive option is ovodonation is the physical resemblance of the baby and its genetics. Many patients do not find it easy not to be the parents genetically speaking when opting for donors. This is why doubts may arise regarding the genetic relationship of your future baby.
Assisted procreation, as any other medical treatment, requires that you rely on the professionalism of the doctors and staff of the clinic you choose. Obviously, each clinic is different.

These doubts that may arise in IVF with ovodonation are known as genetic mourning. More and more fertility clinics are offering psychological support for oocyte donation, or any other fertility treatment.
FAQs from users
Is it normal to have a missed abortion in ovodonation?
Yes, it is possible to have a missed abortion in an IVF treatment with donor eggs.
We define miscarriage as uninduced embryonic or fetal loss before the 20th week of gestation. A missed or delayed abortion is characterized by the arrest of gestation without spontaneous expulsion of the embryo or fetus and usually occurs between the second and third trimester of pregnancy.
As with other types of miscarriages, one of the main causes is a genetic or chromosomal alteration in the development of the fetus. Likewise, infections, endocrine or hormonal disorders or problems in the uterus or cervix can also cause a miscarriage in the first weeks of gestation.
The risk of miscarriage is around 25% after the age of 35, while it increases to 50% in women over the age of 40. If we apply these percentages to egg donation, we know that the risk of miscarriage in egg donation is around 25% because the oocytes come from women under 35 years of age. So it may be normal in an oocyte donation treatment to have a missed abortion.
Will the baby look like the mother in an ovodonation?
Dr. Carolina Arboleya gives us the answer to this question. The doctor tells us:
When we do the matching between the donor and the patient, we have many things in mind. Apart from studying the donor in many aspects so that she can make the donation, in terms of genetic diseases, serological tests, etc. that the battery of tests is very wide, regardless of that, once we have carried out those tests, we do that pairing taking into account the physical characteristics. We take into account the blood group and we take into account general physical characteristics, skin color, eyes, hair, height, hair shape, etc.
Does using donor eggs carry fewer pregnancy risks?
No. When egg donation is used, the possibility of having genetically alternated embryos and, therefore, the risk of miscarriage is reduced.
However, the risks associated with pregnancy are the same as if one's own eggs are used. It is important to keep in mind that advanced maternal age and multiple gestations can cause some risks during gestation, such as pre-eclampsia, gestational diabetes, etc.
