In vitro fertilization programs with donor oocytes allow to achieve pregnancy and the birth of a healthy baby if the patient does not have her own eggs or if they are of very poor quality, and therefore cannot be used in the ART cycle.
Most often, IVF with donor oocytes is carried out if a woman decides to become a mother at a late reproductive age or there is a high risk of transmitting a genetic pathology to the child.
Sometimes, specialists are not able to get the gametes of both spouses. In this situation, programs are implemented either with the simultaneous use of donor oocytes and sperm, or with donor embryos.
IVF with donor eggs can be recommended in the following cases:
Until recently, IVF programs were carried out only using fresh (that is, just obtained) donor oocytes, but now vitrified donor eggs are more often chosen for fertilization. Previously, it was not possible to freeze female sex gametes, since in the process the ice crystals formed that damaged the cell structures of oocytes. The innovative method of ultrafast freezing, which is called vitrification, allows you to ensure that the substance immediately goes into a glassy state, so ice crystals do not form.
When using fresh oocytes, you must first synchronize the menstrual cycles of both women. In order for several oocytes to mature in the ovaries at once, ovulation is stimulated with the help of hormonal preparations. Then, the follicular puncture is performed, as a result of which specialists receive the follicular fluid containing eggs. After this, the oocytes are fertilized with the sperm of the patient’s husband or the donor, the embryos are cultured for several days in special multi-gas incubators, and then 1 or 2 of them are transferred to the uterine cavity of the recipient. The remaining good quality embryos can be frozen and stored in the reproduction center to be used later in the cryocycle.
Why is the use of vitrified oocytes preferable?
The fact is that in this case, financial costs and time are reduced, because:
The IVF program with a personal anonymous oocyte donor includes:
Medicines are paid separately.
The IVF program with vitrified donor oocytes includes:
ART programs using donor genetic material are regulated by order of the Ministry of Health of the Russian Federation No. 107n. All candidates must comply with the strict requirements specified in the document.
Only an adult woman under the age of 35 can become a donor who:
All donors who are in the database of the centers of reproduction and genetics “Nova Clinic” chain underwent a thorough examination in full compliance with the requirements of the Ministry of Health. Since the donor procedure is anonymous, patients cannot personally get to know the donor or see his photos. However, we provide all the necessary information that will help to make a reasonable choice. In particular, patients receive information about the age, height, body type, face shape, hair color, shape and color of the eyes, nose shape, as well as the education and profession of the donor. In addition, the database must contain information about the blood group and Rh factor.
We do not have a waiting list; all oocyte donors can immediately participate in the program.
According to statistics, the efficiency of IVF programs with donor oocytes is higher than in the case of using the patient’s own gametes, due to the excellent quality of the genetic material.
