Cryopreservation

❄️ Cryopreservation

Cryopreservation is a breakthrough fertility technique that allows the preservation of sperm, eggs, and embryos at extremely low temperatures for future use. At Phular IVF Hospital, Muzaffarpur, we offer state-of-the-art cryopreservation facilities to help individuals and couples preserve their fertility and plan pregnancy at the right time.

💡 What is Cryopreservation?

Cryopreservation is a scientific process of freezing and storing reproductive cells (sperm, eggs, embryos) or reproductive tissues at very low temperatures (around -196°C) using liquid nitrogen. This technique ensures that the biological material remains viable and can be thawed and used in future fertility treatments like IVF or ICSI without losing its quality.

🔬 Types of Cryopreservation Services

1. Sperm Freezing: For men undergoing medical treatments (like chemotherapy), working abroad, or unable to provide a sample on the day of IVF. Stored sperm can be used later for IUI, IVF, or ICSI.
2. Egg (Oocyte) Freezing: Helps women preserve their fertility for the future, especially before cancer treatment or for those delaying pregnancy for personal or professional reasons.
3. Embryo Freezing: Allows couples undergoing IVF to preserve high-quality embryos for later transfer — increasing the chances of future pregnancies without repeating stimulation cycles.
4. Ovarian / Testicular Tissue Freezing: Experimental but beneficial for pre-pubertal patients or those undergoing gonadotoxic treatments.

⚙️ How Cryopreservation Works

1. Collection: Eggs, sperm, or embryos are collected in a controlled lab environment.
2. Cryoprotectant Use: Special protective solutions prevent ice crystal formation during freezing.
3. Vitrification (Rapid Freezing): A modern “flash-freeze” technique ensures minimal cell damage.
4. Storage: Samples are stored in liquid nitrogen tanks at -196°C for short or long-term preservation.
5. Thawing & Use: When needed, samples are gently thawed and used in assisted reproduction techniques.

🧬 Who Can Benefit from Cryopreservation?

Men or women undergoing cancer treatments (chemotherapy, radiotherapy)
Couples undergoing IVF treatment who have surplus embryos
Individuals wishing to delay parenthood for personal or career reasons
Patients undergoing surgery that may affect fertility
Couples planning donor egg/sperm IVF cycles

🌡️ Storage Duration & Safety

Cryopreserved samples can be safely stored for many years without losing their fertility potential. At Phular IVF Hospital, all samples are preserved in secure, digitally monitored storage systems under strict temperature control and identity tracking. Each patient’s sample is labeled with a unique identification code for complete confidentiality.
