What is Cryopreservation?

Cryopreservation is the process of freezing and long-term storing biological material (embryos, eggs, and sperm) in liquid nitrogen at −196 °C. This method preserves reproductive cells and embryos for future use without compromising their quality.

Embryo Cryopreservation
During IVF cycles, ovarian stimulation typically produces multiple eggs. After fertilization, several embryos develop, but usually only one or two are transferred per cycle. The remaining viable embryos can be frozen using vitrification—a rapid-freezing method that ensures high survival rates.

Benefits:

• Enables future use of embryos without repeat stimulation and egg retrieval
• Increases chances of pregnancy in subsequent IVF transfers
• Frozen embryo transfer cycles are significantly less costly than fresh IVF
• Risk of birth defects with frozen embryos is no higher than natural conception

Recommended for:

• Women at high risk of ovarian hyperstimulation syndrome
• When the endometrium needs improvement before embryo transfer
• Technical challenges during embryo transfer (e.g., cervical stenosis)
• Egg-donor cycles when uterus synchronization is not feasible
• Prior to cancer treatment (chemotherapy/radiation)

Storage Duration:
 Embryos can be stored for many years, dependent on periodic consent from patients.

Disposition Options:

• Extend storage
• Use for transfer
• Dispose of
• Donate to another couple (with consent)

Embryo Transport
Patients may transfer their embryos between clinics via a signed informed consent form. Embryos are transported in a specially designed liquid-nitrogen container, with responsibility placed on the patient.

Survival Rate:
 In clinics with optimized vitrification protocols, survival post-thaw reaches up to 98%. Typically, a single blastocyst-stage embryo is chosen for transfer.

Egg Cryopreservation
Freezing eggs was once a technical challenge. Today, vitrification allows effective preservation with minimal viability loss.

Indicated for:

• Fertility postponement
• Before cancer treatment
• Low ovarian reserve
• Egg donor programs

Sperm Cryopreservation
At VitroMed Clinic, sperm is cryopreserved using advanced vitrification techniques.

Indications:

• For IVF or insemination programs
• Before fertility-threatening surgery or treatment
• When the partner cannot be present on egg retrieval day
• Oligo- or teratozoospermia cases for sperm banking

Procedure:
 Semen analysis precedes freezing. Samples are processed, concentrated, and frozen in labelled cryovials at −196 °C, maintaining viability for years. Post-thaw processing further enhances sperm quality.

Why Choose VitroMed Clinic?
