Egg, sperm & embryo freezing.

Cryopreservation means freezing reproductive cells or embryos for possible later use. Egg freezing usually involves ovarian stimulation, monitoring, egg collection and freezing of suitable mature eggs. Sperm preservation involves assessment, collection and freezing. Embryo preservation involves fertilization before freezing.

The right approach depends on your medical situation, preferences and consent. Preserving eggs and preserving embryos involve different decisions about fertilization and future use.

Vitrification is the rapid-freezing method described by our clinics for egg preservation. Before treatment, your specialist considers age, ovarian reserve and medical history, and explains what a cycle may reasonably achieve.

Freezing eggs preserves an opportunity, not a guarantee. The number and quality of eggs available, survival after warming, fertilization and subsequent development all influence what may be possible later.

Oncofertility considers preservation alongside cancer care. Other medical circumstances may also lead someone to discuss freezing eggs, sperm or embryos. The timing and suitability of any procedure must be agreed with the treating medical team.

The priority is your health. Contact the specialist promptly if a planned treatment could affect fertility, and do not delay that treatment on your own.

Before proceeding, ask where material will be stored, how storage fees are charged, what consent is required for future use, and how to keep contact details current. If moving material between countries is a future possibility, that needs a separate clinical, transport and regulatory review.

The team can help you distinguish the decision to preserve now from the decisions that may come much later.
