Cryopreservation Procedure
Consultation:
Individuals will have a direct consultation with a specialist doctor to discuss their needs for safe cryopreservation in Kolkata.
Ovarian Stimulation (for egg freezing):
To freeze eggs, you will receive hormone injections for 8-12 days, stimulating your ovaries to produce multiple eggs.
Collection:
Eggs: Eggs are retrieved through a minor surgical procedure called transvaginal ultrasound aspiration. This procedure is done under light sedation and takes about 20-30 minutes.
Sperm: Sperm is collected through ejaculation or, if necessary, testicular aspiration.
Embryos: Embryos are developed through IVF by fertilising eggs with sperm in our laboratory before freezing.
Laboratory Processing:
Our embryologists carefully examine the collected cells under microscopes to assess quality. They also put eggs and embryos in unique culture dishes with nutrients.
Cryoprotection and Vitrification:
The samples are treated with unique protective solutions called cryoprotectants that replace water in the cells. It prevents ice crystal formation, which could damage the cells. Our lab uses a rapid freezing (vitrification) method, transforming the cells into a glass-like state within seconds.
Storage:
The protected samples are placed in labelled straws or vials and stored in tanks filled with liquid nitrogen at -196°C.
Thawing & Usage:
When needed, the samples are carefully thawed and used in assisted reproductive procedures such as IVF or ICSI.
