Sperm Freezing (Sperm Cryopreservation) – A Lifeline for Future Parenthood

What is Sperm Freezing?

Sperm freezing, also known as sperm cryopreservation, is a process where a man’s sperm is collected, analyzed, frozen, and stored for future use. This technique is commonly used for fertility preservation, ensuring that men can have biological children later in life. The frozen sperm can be used for assisted reproductive technologies like in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) when needed.

Semen, the fluid ejaculated from the male reproductive tract, contains sperm. A single ejaculate can carry up to 500 million sperm. When deposited into the vagina, millions of sperm travel through the cervix, and if they reach an egg, fertilization may occur, leading to pregnancy.

Why Do Men Choose Sperm Freezing?

Many men opt for sperm freezing due to various personal, medical, and professional reasons, such as:

• Medical Conditions – Cancer treatments like chemotherapy can harm sperm quality.
• High-Risk Jobs – Soldiers, athletes, and individuals exposed to chemicals.
• Delaying Parenthood – Career-focused men who want children later.
• Sperm Donation – For individuals or couples needing donor sperm.
• Upcoming Surgeries – Such as prostate cancer surgery or vasectomy.

The Science Behind Sperm Cryopreservation

Sperm freezing involves several steps to ensure quality preservation:

1. Collection & Analysis: A semen sample is collected and analyzed for sperm count, motility, and morphology.
2. Preparation: The sperm is mixed with a cryoprotectant to prevent ice crystal formation.
3. Freezing Techniques:
   • Slow Freezing: Gradual cooling to prevent damage.
   • Vitrification: Ultra-rapid freezing to improve survival rates.
4. Storage: Samples are stored in liquid nitrogen at -196°C for years without degradation.

Preparations for Sperm Freezing

Before undergoing sperm cryopreservation, the following steps are taken:

• Completing a questionnaire and consent form.
• Physical examination and blood tests to screen for sexually transmitted diseases.
• Abstaining from sexual activity for a couple of days before providing the sample.
• Immediate or within-the-hour cryopreservation of the sample.

Current State of Sperm Freezing in Nepal

Sperm cryopreservation is gaining popularity in Nepal as fertility awareness increases. Key trends include:

• Growing demand among young professionals and cancer patients.
• Advancements in IVF clinics with state-of-the-art technology.

Legal and Ethical Considerations in Nepal

• Sperm storage requires written consent from the individual.
• Donor sperm usage is regulated under medical guidelines.
• Ethical concerns regarding long-term storage and posthumous use.

How Long Can Frozen Sperm Survive?

Properly frozen sperm, stored at -196°C, can remain viable for decades, though indefinite viability cannot be guaranteed.

What Happens to Thawed Sperm?

Once thawed, the quality of the sperm is assessed, and the most suitable fertilization method is chosen:

• In Vitro Fertilization (IVF): Eggs are retrieved from the woman and fertilized with thawed sperm in a lab before implantation.
• Intrauterine Insemination (IUI): The thawed sperm is inserted directly into the woman’s uterus close to ovulation.

Cost of Sperm Freezing in Nepal

Sperm freezing at leading IVF centers, including Slavica IVF, costs between NPR 15,000 – NPR 40,000, depending on storage duration. Compared to international prices, Nepal offers an affordable yet high-quality service.
