What an embryologist at Embrylife does

preparation of germ cells for fertilization;
selects quality gametes for ICSI;
obtains oocytes during follicular puncture;
performs fertilization using one of the selected methods (standard IVF, ICSI);
works with a complex male factor — separates sperm from a testicular biopsy sample (TESA, TESE) and uses them to fertilize oocytes;
evaluates embryo development;
provides optimal conditions for cultivation;
selects embryos for transfer into the uterine cavity and for cryopreservation; performs auxiliary hatching;
biopsies an embryo for a preimplantation genetic diagnosis — PGD — (analysis is taken to include genetic diseases);
performs sperm preparation and cryopreservation for long-term storage;
freezes embryos, which are further used in cryoprotocols;
thaws germ cells and embryos.

Embryo Culture Protocol

While working with each IVF, the embryologist starts the "Embryo culture protocol". It records patient data from the moment of obtaining oocytes and sperm to the moment of transfer or cryopreservation of embryos: assessment of obtained oocytes on the day of puncture, semen analysis data, fertilization method, assessment of fertilization and stages of development of each embryo up to the 6th day. Such protocols help both reproductive specialists and embryologists and in the event of an unsuccessful attempt they correctly prepare the patient for the next one and make the necessary changes to the protocol. We are ready to provide this protocol at your request.

Embryo reputation

There’s such term as “embryo grading”. Grades of embryos are made up of many factors obtained in the process of observing their "behavior" during first 6 days of their life. Everything is taken into account: which embryo developed better, which one split faster, how it behaved at each stage - all this ultimately affects the fate of the embryo. Therefore, sometimes from two embryos with different characteristics, for example, 5AA and 5AB, the embryologist chooses a second embryo, with seemingly “imperfect” indicators, for transfer.

There are additional methods for predicting embryo implantation (time-lapse, PGS, analysis of metabolites, etc.), which complement the morphological criteria and provide the choice of the best embryo.

With natural fertilization, the embryo is in the uterus only after 5 days, therefore, following natural standards, specialists perform transfer on 5th day.

IVF is a process that needs to be approached individually, taking into account all the nuances that can affect its result. The success of IVF largely depends on how well the doctors managed to create an environment similar to natural conditions for development and maintain it for 5-6 days.

Artificial insemination requires thoroughness, perfectionism and stringency in adhering to all work standards. Therefore, the best embryologists are those who understand the extent of their responsibility.

It should also be noted that the quality of the embryo is not directly related to the chances and outcomes of pregnancy. Many factors influence pregnancy and its development.

And each case is different.
