What is Vitrification?

Vitrification is an ultra-rapid flash-freezing method that transitions cells directly into a glass-like solid state at -196°C. By cooling at rates exceeding 20,000°C per minute, it completely prevents destructive ice crystal formation, achieving greater than 95% post-thaw survival.

Career, Education & Personal Timing

Choosing to freeze eggs in your 20s or early 30s locks in your eggs at peak biological quality and chromosomal normality, allowing you to pursue career and personal goals without biological clock anxiety.

Cancer Treatment & Oncofertility

Chemotherapy, radiation therapy, and extensive pelvic surgery can cause premature ovarian failure. Our rapid oncofertility protocol enables safe egg retrieval within 10 to 14 days prior to cancer treatments.

Endometriosis & Low Ovarian Reserve

Progressive conditions like ovarian endometriomas and early diminishing AMH reserves can rapidly deplete the follicle pool. Freezing eggs early protects against future follicle exhaustion.

Family History of Early Menopause

Women with a familial history of premature ovarian insufficiency (POI) or genetic carrier status can safeguard their biological parenthood options well before ovarian decline begins.

PRESERVATION SUITE

Our Fertility Preservation Options

Individualized cryopreservation protocols engineered for female, male, and couple fertility needs:

For Women

Egg Freezing (Oocyte Vitrification)

Mature eggs are collected under light sedation and flash-frozen within minutes. Ideal for women planning parenthood in their mid-to-late 30s or prior to medical procedures.

For Couples

Embryo Freezing (Blastocyst Vitrification)

Eggs fertilized with partner or donor sperm are cultured to Day 5 blastocyst stage before freezing, providing the highest proven statistical pregnancy rate upon future transfer.

For Men

Sperm Freezing (Semen Cryopreservation)

Ejaculated or surgically retrieved (TESA/PESA) sperm is washed, cryo-protected, and preserved for future IUI, IVF, or ICSI cycles, critical prior to vasectomy or oncology care.

Urgent Medical

Urgent Oncofertility Care

Rapid-start stimulation protocols initiated immediately without waiting for menstrual cycle day 1, safely freezing eggs or sperm before scheduled chemotherapy or pelvic radiotherapy.

Egg Freezing Protocol: Four Steps

4 Clinical Milestones
01
Initial Assessment & AMH Testing

Consultation reviewing reproductive goals, baseline pelvic ultrasound, and serum AMH blood test to determine individual ovarian reserve.

02
Controlled Ovarian Stimulation

Daily hormone injections for 9 to 11 days encourage multiple follicles to mature, tracked via ultrasound scans every 2 to 3 days.

03
Ultrasound-Guided Egg Retrieval

A comfortable 15-minute daycare procedure under light sedation collects mature eggs through transvaginal ultrasound aspiration without cuts or stitches.

04
Flash Vitrification & Cryo-Banking

Mature eggs are flash-frozen at -196°C in liquid nitrogen tanks with automated barcode tracking and 24/7 temperature telemetry.

LABORATORY QUALITY

Scientific Excellence in Cryogenic Storage

Unlike slow freezing methods of the past, our embryology suite uses ultra-rapid vitrification in liquid nitrogen at -196°C. This eliminates cellular damage caused by ice crystal expansion, preserving gamete cellular organelle integrity for over a decade with zero biological aging.

Frequently Asked Questions About Fertility Preservation

The clinically optimal window to freeze eggs is in your late 20s to early 30s (ideally between age 25 and 35), when ovarian reserve is robust and the proportion of genetically normal eggs is highest. However, women in their mid-to-late 30s can also benefit significantly based on an individualized AMH assessment.

Because vitrification halts all cellular biological activity at -196°C, eggs and embryos can remain frozen safely for 10 or more years without loss of viability. Scientific data confirms that babies born from embryos frozen for over a decade are as healthy as those conceived from fresh cycles.

Clinical studies indicate that storing 12 to 15 mature eggs offers a 70% to 80% cumulative likelihood of achieving at least one live birth in women under 35. For women over 35, storing 15 to 20 eggs is typically recommended to compensate for age-related chromosomal changes.

Yes. Long-term medical studies encompassing hundreds of thousands of vitrified cycles show that birth defect rates and developmental milestones in children born from frozen oocytes and blastocysts are identical to those from fresh IVF cycles and natural conceptions.

For cancer patients, we provide emergency oncofertility care with fast-track stimulation protocols that begin immediately regardless of cycle day. Oocyte retrieval is completed safely within 10 to 14 days, avoiding any delay to scheduled oncological treatments.
