Sperm Freezing

What is sperm freezing?

Sperm freezing is a technique that allows us to preserve male fertility without time limits so that it can be used in the future with assisted reproduction techniques.

Factors like stress, alcohol, tobacco and unhealthy eating are some of the main causes for male infertility.

Thanks to our urologist Ricardo García Navas and our endocrinologist Jesús Tresguerres, we can run a complete fertility study in our clinic in order to identify the source of the problem and offer the best treatment to our patients.

Besides, every step of the sperm freezing process takes place in our clinic, therefore decreasing waiting times and increasing the chances of getting pregnant.

When is it useful?

For patients who have to undergo treatments that may reduce or destroy their fertility (testicle or prostate surgery, chemotherapy, radiation therapy).

When it is difficult to obtain a sperm sample for assisted reproduction treatment, for both psychological and logistical reasons.

Progressive deterioration of sperm quality due to a known or unknown cause.

Oligozoospermia (low quality sperm with reduced motility).

Prior to having a vasectomy in case you would like to become a father in the future.

Due to infected samples (HIV, hepatitis) after sperm washing.

Procedure

Preparation: before cryopreservation we will need to determine the risk of infection by taking a blood sample to check for HIV, syphilis, and hepatitis B and C.

Collecting the sample: the patient will bring a sperm sample to the clinic in person. We recommend 3 to 5 days of abstinence.

Analysis: the sample will be analysed in the lab and the patient will be informed as to whether or not the sample is sufficient, or if he will need to bring in another sample in order to have a sufficient amount of spermatozoa.

Freezing: the sample is prepared with cryoprotectors and the temperature is lowered gradually before being stored in liquid nitrogen at -196ºC.

Why are there men who decide to freeze their sperm?

Other than because of oligoasthenozoospermia (low sperm quality and motility) and for patients who underwent a vasectomy, one of the main reasons men decide to freeze their sperm is fertility preservation before a treatment for cancer since many of the medicines used for chemotherapy and radiotherapy can have a negative impact on the quality of sperm.

Therefore, the solution is to freeze sperm following the right steps in order to use it later on.
