Cryopreservation of the germinal material – it is a procedure for patients who want to postpone the implementation of their biological function – birth of a child. Young women, who are busy with their careers, freeze their egg cells and embryos derived from IVF for the future because they understand that with age, chances of becoming pregnant are reduced. In addition, people who have a work-related risk of life, or before surgery, chemotherapy or irradiation, also freeze and store their cells.
Cryopreservation of semen
Cryopreservation of sperm is carried out according to different indicators: for the insemination by a husband or donor sperm, for the IVF, for the storage before future operation, after which a sharp decrease in fertility can be made.
In practice, sometimes there is a need for cryopreservation of sperm in cases where a person can not be present in the clinic on the day of the puncture of the follicles of his wife or her insemination with sperm of her husband. This does not reduce the chances of conception.
Thus, cryopreservation of sperm can not only increase the chances of conception in a married couple, but also will save money after the success of the first cycle of IVF when freezing several portions.
Cryopreservation of embryos
If during the procedure of IVF it is possible to obtain more embryos than it is necessary for one transferring, if it is desired, they can be stored at a very low temperature – to carry out cryopreservation of embryos. These embryos are property of the pair and can be used later for the next IVF attempt. The advantage of cryopreservation is that, in obtaining an additional chance, a woman avoids the procedure of stimulation and puncture of the follicles and prepares only for the transferring of the embrio.
Cryopreservation is a kind of “biological support” for a couple: it is impossible to predict exactly whether stimulation and fertilization will be successful in the next attempt. Keeping the embryos which were left, the couple increases their chances. Cryopreservation also gives the patients economic benefit – the cost of storage, defrosting and transferring of the embrio is lower than the “fresh” attempt of IVF.
Cryopreservation is a reliable and proven method. No negative effects on the fetus and the course of pregnancy associated with cryopreservation have been detected. A disadvantage is the possible loss of embryos in the process of freezing and defrosting – not all embryos remain viable. It is very important that you discuss with your doctor the necessity of freezing your embryos before you start preparing for the IVF procedure.
Cryopreservation of egg cells
Egg freezing allows a woman to preserve her fertility until she is ready to start her family.
During an egg-freezing cycle, a patient will go through many of the same steps that are involved in a typical IVF cycle: ovulation stimulation, ultrasound monitoring, and egg retrieval. After egg retrieval, the eggs will be cultured for a few hours and then frozen the same day for future application.
