Popular IVF programs
Frozen embryo transfer is considerably less complicated than the classic IVF program. It consists of three stages: getting the endometrium ready, transferring the embryos and maintaining the luteal phase.
Frozen embryo transfer is one of ART techniques.
Basically, it is an in-vitro fertilization program minus the stimulation stage. This technique is advisable when the IVF protocol for some reason was unsuccessful. By preserving the embryos, the parents receive a kind of moral support boost, because even if the first try fails, there is always a second chance. Besides, it will be easier and a lot cheaper.
Many couples choose to tray frozen embryo transfer program after a successful IVF attempt to have a second baby.
The end result of this technique depends on various factors which include:
Some scientists claim that the high dosage of hormones that women are injected with during the stimulation can alter the qualities of their endometrium and may have negative effect on its ability to accept and nourish the embryo.
If the patients use the frozen embryo transfer program, there is no need to do take hormones in such high doses, which makes this program closer to the natural way of things. Consequently, the pregnancy is likely to go more smoothly from the physiological point of view.
Is it necessary for the father to do a medical check-up with this protocol? Yes, it is. Even though he is not actually involved in the process of the transfer and has done the required tests during the first cycle, the frozen embryo transfer recommendations list does contain several obligatory examinations. As for the mother, out of all the usual hormone level exams she only has to do the progesterone blood test, because this hormone is prescribed to ensure a healthy pregnancy.
Sometimes, though fairly rarely, the usual superovulation stimulation protocol is still required to prepare the endometrium for the transfer. This happens when there is no natural ovulation and if the standard preparatory procedures yielded no results.
Regardless of their education level, many people still consider embryo cryopreservation a dangerous procedure that has the potential to harm their future baby. Sometimes, it may be hard for the parents to understand this process. These couples would rather dispose of their spare embryos, which is completely unnecessary and unfounded, just because they are afraid to freeze it.
However, it is essential to realize the difference between a common freezing and cryopreservation. When you freeze something the usual way, the water in the issues crystalizes under the influence of low temperatures and destroys the cell membranes. Cryopreservation in liquid nitrogen happens at the ultra-low temperature of -196 С°. Under these conditions, the ice simply does not have enough time to form. After they are defrosted, more than a half of all embryos can be successfully implanted into the womb tissue and start developing there. Out of 100 frozen embryos, only 5 or 6 of them are lost. Studies have proved that in those cases the cause of death is not related to cryopreservation, but is normally of genetic origin. Large-scale case studies have also demonstrated, that children born from frozen embryos are not any different from other children in terms of general health and course of development, and the pregnancy is usually less problematic. It might be connected to lower amount emotional stress for the parents.
Frozen embryos can be preserved for a very long time. An additional prove to that is the birth of a girl named Emma in 2017. Her embryo has been cryopreserved for 25 years, since 1992. The only condition is to strictly abide by the rules of cryopreservation and defrosting procedures.
In Altravita we use various ART techniques. Thanks to high-level equipment and the skills of our doctors, we keep our statistic results up to the highest standards. You can get more information about cryopreservation from our gynecologists. Call the clinic using the phone number on our website and make an appointment.

What is IVF in natural cycle? IVF in natural cycle uses ultrasound monitoring of growth of the dominant follicle in the ovary of the patients with preserved ovulation.
With a follicle size of 18 mm, either under the control of an ovulation test, or after the intramuscular injection of an ovulation trigger, a follicle is punctured to obtain an egg. The rest of the IVF program process remains the same.
To increase the effectiveness of IVF, the program includes the study of egg’s spindle apparatus.
The reason for the low demand for IVF in the natural menstrual cycle is that it is characterized by a fairly low efficiency. The pregnancy rate is lower than with insemination in the natural cycle, it is about 7% in terms of each started cycle.
This is due to the fact that not every mature follicle is an egg carrier. In addition, because of the puncture, only one egg is extracted, which may not be able to fertilize. Also, when using this method, there is a risk of canceling the oocyte collection procedure due to premature ovulation.
The advantage of this method is to minimize the risk of complications such as ovarian hyperstimulation syndrome.
The undoubted advantages of the IVF method in the natural cycle include the possibility of carrying out the procedure for several menstrual cycles in a row. However, note that a single puncture of stimulated ovaries will do less harm than multiple.
Another advantage of IVF in natural cycle is that comapered to other programs its cost is usually lower than in programs where superovulation stimulation is performed.
Also, unlike in other programs, no special preparation for IVF in the natural cycle is not required.
IVM means in vitro egg maturation (in vitro) followed by IVF. The specialists of AltraVita clinic have sufficient capabilities and knowledge to conduct this process with high efficiency, as evidenced by reviews of IVF in natural cycle.
The combination of IVM and IVF methods makes it possible to simultaneously obtain a mature egg from a dominant follicle and a number of immature eggs from small (antral) follicles. Egg maturation takes place “in vitro”, and a mature egg undergoes fertilization in the standard way. High-quality embryos obtained by both methods are transferred into the uterus.
