Cryocycle means usage of frozen embryos in repeated treatment cycles. In a treatment cycle like this, the multifollicular ovarian stimulation is not performed, and this leads to alower hormonal influence on the organism of the future mother. This significantly increases the chances for pregnancy onset.
Cryocycle is recommended in the following cases:
• after failed IVF attempt;
• if the couple already has plans for the second and third child while planning their first IVF;
• if there is a cancer condition and the upcoming treatment may affect further ability to reproduction;
• in the presence of diabetes mellitus or azoospermia in men.
The appliance of cryocycle has a number of advantages for the patient, namely:
• an opportunity to postpone the implantation of the embryo into the uterine cavity for the time needed for woman’s body to restore after hormonal hyperstimulation. By postponing the embryo transfer for a month or more, doctors are able to stabilize the hormones, therefore the probability of successful IVF program increases significantly;
• an opportunity to avoid one of the most dangerous complications of IVF program – multiple pregnancy. The development of multiple pregnancy has great risks for the successful pregnancy flow and the birth of healthy children;
• an opportunity to perform genetic diagnosis of the embryo using NGS method, which makes possible to identify embryos bearing chromosomal pathology and thus prevent failed IVF due to the natural ability of the uterus to reject an unhealthy embryo;
• reduction of financial costs of patients if the first IVF attempt failed – cryocycle allows avoiding repeated ovulation stimulation and using.
