Sperm is one of the germ cells of the human body, which can be frozen and stored for years.
What is the purpose of sperm freezing? Mostly for later use for reproductive reasons, such as IVF (In-vitro fertilization) or IUI (intrauterine insemination). As well as sperm donation.

Sperm freezing is a procedure of collecting, analysing, selecting and freezing.

Normally, sperm collection is through masturbation, or for patients with ejaculatory dysfunction, Doctors might perform surgery to collect sperms. For example, MESA (sperm aspiration from the epididymis by means of microsurgery), TESA (sperm extraction from the testicles by means of a biopsy).

Patients can choose to collect a sample in either their home or in our clinic.

As we mentioned before, the stored sperm sample can be used for IVF and IUI later on. But for patients collected sample through MESA/TESA, IVF Is highly recommended. Aimed to increase the successful pregnancy rate with limited sample size.

Before the sperm cryopreservation, there is some preparation to do:

• Blood test for infection screening, eg. HIV, RPR, hepatitis.
• If you have a previous semen analysis report, please provide to us for reference.

The technology we are using to freeze the sperm now is the vitrification. Compared to the traditional method, this new technology uses less time to finish the freeze, lowering the harm that can possibly be made during the procedure.

The sperm sample will be analysed and selected immediately. Approximately 1-2 hours after, the sample will be frozen for storage.

For the post thawed survival rate, it’s around 20-50%, depends on the quality of the sperm sample.

You can find all the blood test results (HIV, RPR, hepatitis) in our self developed app. As well as the semen analysis report. With the list of sperm samples that had been frozen.

Freezing germ cells allow us to preserve our fertility. Using the frozen cell at a later date, age is no longer an obstacle for conceiving an offspring.

Common reasons to choose to freeze sperm:

• Advancing age
• Cancer or other medical reasons
• Transgender patients
• Career and lifestyle choices, such as studying aboard for higher educational activities
