A cryopreservation technique involves freezing eggs (oocytes), embryos, or sperm at sub-zero temperatures (-196°C) using liquid nitrogen for future use in In Vitro Fertilization (IVF). Frozen sperm may also be used in IUI (intrauterine insemination) treatment cycles.
At Nandi IVF, we use the gold standard in cryogenic storage—ultra-rapid vitrification—which prevents the formation of ice crystals within delicate reproductive cells, achieving survival rates above 95% upon thawing.
24/7 temperature-monitored liquid nitrogen tanks ensure gametes and embryos remain biologically viable indefinitely.
Individualized freezing options crafted for medical indications and personal reproductive choices.
Infertility treatments typically stimulate multiple eggs. Extra high-quality embryos formed in the laboratory can be frozen between days 1 and 6 (blastocyst stage) for future frozen embryo transfer (FET) cycles without requiring another round of ovarian stimulation.
Cryopreservation of oocytes allows women to freeze unfertilized eggs when their reproductive potential is at its peak. This safeguards against age-related egg decline or fertility risks caused by oncological treatments, medical surgeries, or lifestyle timing.
Sperm freezing preserves male fertility prior to chemotherapy, prostate/testicular procedures, vasectomy, or military deployment. It is also used during IVF and IUI procedures when the male partner cannot be present on egg collection day.
Patients preparing for chemotherapy, radiotherapy, or surgical procedures that might impact future fertility.
Women wishing to delay pregnancy for career, education, or personal life goals without compromising biological age advantages.
Surplus viable blastocysts are preserved for future sibling births or subsequent cycles with 0 extra stimulation injections.
Receive personal counseling to understand egg reserve (AMH), optimal freezing timelines, and transparent long-term storage plans.
