What is Cryopreservation?
Cryopreservation is a highly advanced medical process that involves freezing and storing reproductive cells or embryos at extremely low temperatures for future use. At Zemya IVF & Fertility Clinics, Cryopreservation is a core part of many fertility treatments, offering patients the flexibility to plan parenthood when the time is right.
Using a technique called vitrification, sperm, eggs (oocytes), and embryos are rapidly frozen and stored in liquid nitrogen at -196°C. This process halts all biological activity, allowing the cells to remain viable for many years until they are thawed for use in treatments such as IVF or IUI.
Cryopreservation gives couples and individuals the ability to safeguard their fertility, particularly in cases of medical treatments, age-related decline, or lifestyle planning.
What Can Be Cryopreserved?
At Zemya IVF & Fertility Clinics, we offer Cryopreservation services for:
- Eggs (oocytes): Preserving female fertility for future pregnancy
- Embryos: Created during IVF and frozen for later use
- Sperm: Stored for men undergoing treatments or fertility preservation
- Testicular or epididymal sperm: Retrieved surgically and frozen for IVF
- Ovarian and testicular tissue (in select medical cases): For fertility preservation in cancer patients
Each sample is carefully handled by experienced embryologists and stored securely under regulated conditions to ensure maximum viability and safety.
Who Should Consider Cryopreservation?
Cryopreservation is recommended for a variety of medical and personal reasons, including:
- Women who want to delay motherhood but preserve younger, healthier eggs
- Cancer patients undergoing chemotherapy, radiation, or surgery that may affect reproductive organs
- Men with low sperm count or undergoing vasectomy
- Couples undergoing IVF with extra embryos after a transfer
- Individuals with conditions like endometriosis or autoimmune diseases
- LGBTQ+ individuals planning for future family building
- Patients undergoing gender-affirming treatments
- Those with genetic or family histories of early menopause or fertility decline
Whether for medical reasons or lifestyle choices, cryopreservation gives you control over your reproductive future.
Benefits of Cryopreservation
Cryopreservation offers several key advantages:
- Preserves fertility before medical treatments that could impair reproductive function
- Allows flexible planning of pregnancy without compromising future chances
- Reduces the need for repeat egg or sperm retrieval procedures
- Enables multiple embryo transfers from a single IVF cycle
- Supports donor sperm or donor egg programs with precise timing
- Increases the success rate of IVF by synchronizing embryo transfer with endometrial readiness
Cryopreservation also helps reduce emotional stress by giving patients more time to make informed reproductive decisions.
How the Cryopreservation Process Works
The Cryopreservation process at Zemya IVF & Fertility Clinics is carefully monitored at every stage:
Step 01
Collection
Eggs, sperm, or embryos are collected through standard IVF or fertility procedures.
Step 02
Evaluation
Samples are analysed for quality. Only healthy, viable cells are selected for freezing.
Step 03
Preparation
A special cryoprotectant solution is added to protect the cells from damage during freezing.
Step 04
Vitrification
The sample is rapidly cooled in a vitrification machine, avoiding ice crystal formation.
Step 05
Storage
The frozen samples are placed in liquid nitrogen tanks, where they are safely stored long-term.
Step 06
Thawing
When the patient is ready, samples are thawed in a controlled environment for use in IVF or IUI procedures.
At every step, our team follows strict quality control standards to ensure maximum safety and the best possible outcome.
How Long Can Cryopreserved Samples Be Stored?
Cryopreserved sperm, eggs, and embryos can be stored safely for many years, often 10 to 20 years or more, without any significant loss in quality. The samples remain viable as long as they are properly stored and monitored. At Zemya IVF & Fertility Clinics, we offer flexible storage plans to match your fertility goals and timeline.
Is Cryopreservation Safe?
Yes. Cryopreservation is a widely accepted and safe procedure used by fertility clinics across the world. The survival rates for thawed eggs, embryos, and sperm have significantly improved with vitrification technology. Numerous healthy babies have been born from frozen embryos and gametes.
All procedures at Zemya IVF & Fertility Clinics are performed by certified embryologists using FDA- and ICMR-compliant protocols to ensure safety, hygiene, and traceability.
