Will there be any damage to the frozensperms due to semen freezing and thawing?

In frozen semen sample, there may be 20%, but not significant reduction in the sperm motility after thawingit.

Who all can benefit and what are the indications for semen sample freezing?

Sperm cryopreservation for male fertility preservation is offered for the following cases:

• When there is a risk of reproductive ability loss (testis removal, chemotherapy, radiotherapy.)
• When the male partner will not be in station on the day of oocyte retrieval.
• When the male partner has difficulty in providing semen sample on demand
• In cases of surgical sperm recovery.
• In cases of sperm recovery using electro ejaculation.
• In cases of ejaculation problems.
• In cases of progressively declining sperm quality.
• Before sterilization by vasectomy.
• Donor semen sample programme

What are the instructions to be given or prerequisites prior to semen sample freezing?

• Should be tested for infectious diseases including HIV, Syphilis, Hepatitis B and Hepatitis C within 6 months of providing semen sample.
• The man should have abstinence of 2-3 days prior to the day of providing semen sample.
• A written consent form is taken prior

How many sperm samples to freeze?

Sperm may not be able to maintain their viability and mobility during the freezing and thawing processes. In general, around 50% – 80% of the sperm can survive after thawing, and the percentage is even lower if the quality of the pre-freeze sample is already not the best.

For men who are freezing the sperm as a backup storage for fertility treatment, one sample is usually adequate.

For men who are freezing the sperm for fertility preservation because of a medical condition, the underlying disease may have caused a reduction in the sperm count and motility. In such situations, it may be advisable to freeze more than one sample if possible, preferably between two to five, depending on the time interval before surgery, chemotherapy or radiotherapy, so that there will be adequate sperm for use in the future after thawing.

What happens when a man wants to use his sperm?

When the man is ready to use his sperm, the sperm are thawed and used in fertility treatments. The type of treatment depends on the number of cryotubes in storage and the sperm quality. Frozen sperm can be used for intrauterine insemination (IUI) if the sperm quality is good. If the sperm quality is poor, it may be necessary to undergo in-vitro fertilization (IVF) or even intracytoplasmic sperm injection (ICSI) whereby a single sperm is injected directly into an egg to assist fertilization.

How long can the sperm are stored for?

Currently if a man is storing sperm for social reasons, the sperm can only remain in storage for up to a maximum of 5 years.

Can own sperm be donated if decided not to use it further?

Own frozen semen sample cannot be donated. It can be discarded or used for teaching purpose.

Do you need to pay if you want to continue semen freezing for future use?

Constant maintenance of semen freezing need frequent use of liquid nitrogen to fill the cryo tank. Fixed charges should be paid periodically once in every 6 months or every 12 months.
