Embryos are the cornerstone of the pregnancy process. Embryos are frozen so they
can be used at a later stage. The difference between the cryopreservation of eggs and sperm
and the cryopreservation of embryos is that in the case of embryos,
fertilisation has already taken place.
The patients visit the clinic for a consultation with a fertility specialist and an embryologist. A host of medical tests are performed to determine the status of sperm (in the male partner) and eggs (in the female partner), along with their quality and motility.
Patients are provided with medications that enhance hormonal stimulation, which increases the number of healthy sperm (in male partners) and eggs (in female partners).
The male partner provides the clinic with a semen sample and the female partner undergoes egg retrieval in an operating theatre under sedation. The egg retrieval process collects the eggs, which will be fertilized in an advanced ART laboratory.
The healthy embryos are then frozen using vitrification technology. Usually, embryos are frozen for one year. However, the duration can be extended with the consent of the couple.
