Fertility Preservation (Egg / Sperm Freezing)
Vitrifying and storing healthy eggs, sperm, or embryos for future use.
Fertility Preservation allows individuals to freeze and store their reproductive cells (eggs, sperm, or embryos) to protect their chances of conceiving a biological child in the future. Using an ultra-rapid cooling technique called vitrification, cells are frozen in liquid nitrogen at -196°C, halting biological time without causing structural damage. This option is widely used by individuals choosing to delay parenthood for career/personal reasons, or patients undergoing medical treatments (like chemotherapy or radiation) that affect reproductive health.
Who is Advised Fertility Preservation (Egg / Sperm Freezing)?
Clinicians generally recommend this therapy path for individuals or couples experiencing the following conditions:
- Women wishing to preserve egg quality before age-related decline (ideally under age 35):
- Patients diagnosed with cancer or conditions requiring gonadotoxic treatments:
- Men with progressive decline in sperm parameters or undergoing testicular surgery:
- Couples undergoing IVF who wish to freeze excess healthy embryos:
Process Overview & Procedure Steps
Stimulation (for women)
10-12 days of hormone treatment to mature multiple eggs.
Retrieval
Ultrasound-guided collection of eggs under sedation.
Vitrification
Eggs or semen samples are rapidly frozen in liquid nitrogen.
Cryostorage
Stored in secure tanks at partner facilities until ready for use.
🕒 Treatment Timeline
For egg freezing, the preparation and retrieval process takes about 2 to 3 weeks. Sperm freezing can be completed in a single day, though multiple samples may be stored over a week.
📋 Clinical Diagnostics Required
- Ovarian reserve tests (AMH, AFC count) for women
- Semen analysis for men
- Screenings for blood-borne viral infections (HIV, Hep B/C)

Frequently Asked Questions — Fertility Preservation (Egg / Sperm Freezing)
How long can frozen eggs or sperm remain stored?
Theoretically, cryopreserved cells can remain frozen indefinitely without losing quality. Under Indian law (ART Act 2021), clinics are authorized to store cells for defined multi-year terms, which can be extended upon request.
What is the best age to freeze eggs?
The ideal age window is during a woman's 20s and early 30s (ideally before age 35), when ovarian reserve is high and eggs have lower chromosomal abnormalities.
