Sperm Freezing in Malaysia | Advanced Fertility Preservation

Sperm freezing, also known as sperm cryopreservation, is a process where sperm cells are collected, frozen at very low temperatures, and stored for future use.

It allows men to preserve their fertility by storing healthy sperm in liquid nitrogen at –196°C for future pregnancy attempts.

When needed, the sperm is thawed and used in fertility treatments such as IVF or IUI.

Sperm freezing is suitable for a wide range of male individuals.

You may consider sperm freezing if you:

• are delaying fatherhood for career, education, or personal reasons
• are about to undergo treatments such as chemotherapy or radiotherapy
• have a medical condition that may affect fertility
• are unable to be physically present at our centre on your spouse’s Oocyte Pick-Up (OPU) day

At Sunfert, we follow strict laboratory protocols to ensure optimal preservation and safety.

The entire process of sperm freezing can be done within 5 steps:

Step 1: Fertility Evaluation

During a fertility assessment, we will review the patient’s medical history and semen analysis to assess sperm quality and reproductive potential.

Step 2: Semen Collection

Semen collection is typically performed through masturbation in a private room at our fertility centre. Alternatively, patients may choose to collect the necessary collection kit from our nursing team and prepare the semen sample at home, allowing them to do so in a more comfortable and familiar environment.

Step 3: Semen Analysis

Our embryology team will then conduct a semen analysis in the lab to evaluate sperm health from 3 different aspects to identify the best semen samples for freezing.

• Sperm Count (volume): Measure the number of sperm presence in semen. A lower count can reduce the chances of fertilisation.
• Sperm Motility (movement): Measure how well sperm move. Poor motility makes reaching the egg more difficult.
• Sperm Morphology (shape): Identify the shape and structure of sperm. Abnormal forms may struggle to fertilise an egg.
  
   

Step 4: Freezing Process (Cryopreservation)

Healthy sperm will be first mixed with a specialised cryoprotectant solution, which helps protect the sperm cells from damage during the freezing process.

The sperm will then be carefully placed into sterile cryogenic storage containers, such as labelled straws or vials. These containers are sealed and gradually cooled before being stored in liquid nitrogen tanks at extremely low temperatures of around –196°C.

Step 5: Future Fertility Use

When ready, frozen sperm can be thawed, and prepared for IVF or IUI procedures.

Question #1: Is sperm freezing safe?

• Yes. Sperm cryopreservation is a well-established and safe procedure used worldwide for decades in fertility treatment.

Question #2: Does freezing damage sperm?

• Some sperm may not survive the thawing process, but modern freezing techniques significantly minimise damage. Surviving sperm can still successfully fertilise an egg through IVF or IUI.

Question #3: Can frozen sperm result in a healthy pregnancy?

• Yes. Numerous healthy pregnancies and births have resulted from frozen sperm used in assisted reproductive treatments.

Question #4: When should sperm freezing be done?

• Ideally, sperm should be frozen before: Starting cancer treatment, undergoing major reproductive surgery, or experiencing significant decline in sperm quality.
