Sperm Freezing

We'll talk about sperm freezing, and how to do it The most important reasons that may push a man to request sperm freezing?


How is sperm stored with cryopreservation (sperm freezing)?

Sperm is stored in refrigerators that contain liquid nitrogen, where the volume of each semen sample, the concentration of the number of sperms in it and the rate of movement of these sperms are determined by using one or more packages for each sample depending on the size and quality of the sample, as the volume of the ejaculate ranges between 1.5 and 5 milliliters, They are placed in one or more packages where one package can contain a maximum of 2 ml.

The semen sample will be mixed with the freezing medium according to certain techniques and under special conditions that allow the sperm to survive the freezing and storage process.


How many samples should be frozen?

The decision about the number of samples to be frozen is up to the specialist doctor, but studies recommend freezing at least two samples before performing surgery or treatment, and it is preferable to freeze a larger number if the treatment is difficult and is likely to lead to infertility. For example, when treating testicular cancer, the doctor will expect that this treatment will greatly harm the fertility of the patient, and this will prompt him to request to freeze a larger number of samples, and there are other factors that must be taken into consideration, such as the number of children the patient hopes to have, and doctors recommend freezing more samples if the quality of the fluid is Low sperm count or low sperm count. It should be noted that the number of samples needed for storage differs from one person to another due to the difference in the quality of the sperm after thawing it. After dissolving the sperm sample, the testers analyze the movement of these sperms through a test called the solubility test.

Newer tube-baby techniques can handle poor quality semen, so it is recommended to freeze any sperm even if they are of poor quality or have a low sample concentration.


Freezing harmful to sperm?

The sperm freezing technique is successful, it is known that the viability, movement and vitality of cryopreserved sperm lasts for a long time, as cryopreserved samples have been used for more than 20 years to obtain successful pregnancies and healthy babies. There is no limit to the length of time the sperm is stored, but the most important thing is to preserve the semen at a low temperature (-196 degrees Celsius). Therefore, liquid nitrogen cooling techniques are used.


What should be done before freezing sperm?

Sperm freezing is an easy procedure, as it does not require much preparation, nor does it require surgery, anesthesia, or the like. However, marital relations or ejaculation of semen should be avoided for several days before the sample is given, in order to ensure a good sperm count in the semen.

Of course, this technique differs from taking sperm by surgery, as this is another technique that is resorted to when the number of sperms is small. Where doctors resort to a testicular biopsy by pull (TESA) or testicular inspection (TESE) to take the sperm, and the sperm obtained through surgery can be used directly or frozen.


How is frozen sperm used?

These sperms are used for intrauterine injection (IUI), where a sample of sperm is injected into the woman's uterus, and more commonly it is used in IVF techniques. Where the infertility specialist will determine the appropriate day for the use of sperm, based on specific procedures that are performed, including ovulation induction, hormone monitoring, endometrial monitoring, etc.


Is pregnancy guaranteed using frozen sperm samples?

There are no guarantees in IVF, so even if many samples are frozen and used carefully, pregnancy failure is a possibility. Therefore, specialists with long experience in the treatment of infertility should be consulted, and with extensive knowledge of the most important and latest technologies used, the experience of the doctor, the competence of the medical staff working in the center, and the quality and modernity of its equipment will greatly improve the chances of pregnancy.
