Cryopreservation – Preserving Fertility for the Future

Modern fertility care is not only about achieving pregnancy today but also about preserving the ability to conceive in the future. Thanks to advances in reproductive medicine, Cryopreservation—the process of freezing and storing eggs, sperm, and embryos—has become a vital tool for individuals and couples who wish to delay parenthood or safeguard their fertility due to medical or lifestyle reasons.

At Karnic Clinic, we offer state-of-the-art cryopreservation services, ensuring that your reproductive material is stored safely, effectively, and ready for use whenever you decide to start a family.

What is Cryopreservation?

Cryopreservation is a scientific technique where biological materials like eggs, sperms, or embryos are frozen at ultra-low temperatures (-196°C) using liquid nitrogen. At this temperature, all biological processes stop, and the gametes or embryos can be preserved for years without deterioration.

When you are ready, the samples are thawed, and fertility treatments such as IUI, IVF, or ICSI are performed to help achieve pregnancy.

 

Types of Cryopreservation at Karnic Clinic

1. Egg Freezing (Oocyte Cryopreservation):
   • For women who want to preserve their eggs for future use.
   • Eggs are retrieved, frozen using vitrification (a rapid-freezing method), and stored.
   • Useful for women delaying pregnancy for career, education, or personal reasons, or those undergoing medical treatments like chemotherapy.
2. Sperm Freezing (Semen Cryopreservation):
   • A simple and effective method to preserve male fertility.
   • Beneficial for men undergoing cancer treatments, surgeries, or those at risk of fertility loss.
   • Also useful for men who cannot be present on the day of IVF or IUI.
3. Embryo Freezing:
   • Fertilized embryos (created through IVF or ICSI) are frozen for future use.
   • Provides higher chances of pregnancy in subsequent IVF cycles without repeated ovarian stimulation.
   • Particularly helpful after successful IVF cycles where extra healthy embryos are available.

 

When is Cryopreservation Recommended?

For Women:

• Delaying childbearing due to career, education, or personal choice.
• Low ovarian reserve or family history of early menopause.
• Medical conditions like cancer requiring chemotherapy or radiotherapy.
• Risk of ovarian surgery leading to reduced egg count.

For Men:

• Prior to cancer treatments like chemotherapy or radiotherapy.
• Low sperm count or poor semen quality that may deteriorate with time.
• Difficulty producing a semen sample on demand.
• Preserving fertility before vasectomy or other surgeries.

For Couples:

• Preserving surplus embryos after IVF for future cycles.
• Preventing the need for repeated ovarian stimulation.
• To reduce costs and efforts in future IVF attempts.

 

Benefits of Cryopreservation

Fertility Assurance – Provides individuals and couples with the freedom to plan parenthood without worrying about age-related fertility decline.
Medical Security – Protects fertility before treatments like chemotherapy, radiotherapy, or surgeries that may impair reproductive health.
Cost-Effective for IVF Couples – Frozen embryo transfer (FET) is less expensive and less stressful than undergoing repeated IVF cycles.
Flexibility – Allows couples to attempt pregnancy at the right time, both emotionally and physically.
High Success Rates – Modern vitrification techniques ensure excellent survival rates of eggs, sperm, and embryos after thawing.

3. Freezing (Vitrification/Slow Freezing) – Rapid freezing under controlled lab conditions.
4. Storage – Preserved in liquid nitrogen tanks at -196°C with strict monitoring.
5. Thawing & Fertilization – When required, samples are thawed and used for IVF, ICSI, or IUI.
