The Time Lapse method in IVF treatment
During In-vitro Fertilisation (IVF) for couples wanting to have a baby, fertilisation of the egg and the first days of maturation take place outside the woman's body. With the help of small incubators, we imitate the environment in which eggs develop during a usual pregnancy. In order to create ideal conditions, we use modern technology.
With the Time Lapse method, the embryos are photographed every 5 minutes by a microscopic camera built into the incubator. The images are continuously compiled by means of a microchip to form a film sequence called a Time Lapse. This can be used to help monitor the development of the embryos in the laboratory and accurately assess their status.
By comparing the individual images, our team of experts can determine the embryo development and division process. This allows for accurate conclusions to be drawn about an embryo's capability for implantation - the Time Lapse method allows us to pick the best timing for embryo transfer.
The developmental stages of the embryo can be observed 24 hours a day without opening the incubator – that is, without disturbing it. This process guarantees a constantly optimal atmosphere with stable temperature, air, light and humidity conditions. Camera movements are also kept to a minimum, in order to minimise any potential interference with the conditions for cultivation.
The usual need to remove the embryo from the incubator to check it and identify the best possible timing for transfer is thus avoided. Any fluctuations in temperature, PH value, light or slight vibrations, which could have a negative effect on the development of the embryo, can also be detected.
The Time Lapse method is integrated into our high-tech Geri® incubators. These are also equipped with private chambers, always for one patient at a time - this helps to avoid any confusion. The Geri® incubators also contain numerous other technical monitoring equipment to create the best possible developmental conditions for the embryo. This way, we come as close to natural conditions as is currently possible.
