Semen is the fluid that contains sperm. Freezing involves the collection and storage of semen for future use.
Before collecting the sample, tests will be carried out to rule out not having infectious diseases, such as HIV and hepatitis, and to make sure that its storage is safe avoiding cross contamination.
To obtain the best quality sample, you should not have sexual intercourse or masturbate for 2-3 days prior to collection. In some cases, it is possible to collect the sample at home, but you will need to bring it to the clinic no later than an hour.
Although the deterioration of the semen is not as abrupt as the production of oocytes in women. It must be considered that from 50 to 55 years there is a progressive loss of seminal quality.
They can benefit from this technique:
• Young people who have passed puberty in need of treatment that could have reduced their fertility.
• Men who require chemotherapy or radiotherapy treatment because they have been diagnosed with cancer.
• Men with low sperm count or difficulties in obtaining the sample, prior to In vitro fertilization (IVF). The purpose is to ensure that sperm are available on the day of the follicular puncture.
• Men who plan to have a sex change procedure.
• In cases where men are planning to have a vasectomy, in case they decide to have more children in the future.
• Men who are at risk of injury or death. Members of the Armed Forces.
• Semen banks, men who simply want to help single expectant mothers or infertile couples to have children.
• Cases with azoospermia to search for sperm by testicular biopsy and see the possibility of later in vitro fertilization (IVF / ICSI).
Sperm cryopreservation is carried out through a slow freezing process. Cryoprotectants are added and it is normally distributed into straws, and finally they are stored in liquid nitrogen, at -196ºC.
The duration of frozen semen in principle is indefinite, having obtained pregnancies until more than 15 years after freezing.
The age to freeze is not a limiting factor, it is only necessary to consider that there is a good seminal quality, especially when it is performed as an aid to women who need it, although this is not vital when we face reproductive treatment that many times is not works with the best seminal quality.
CONCLUSIONS
Semen freezing is important both to preserve fertility and to support in vitro fertilization techniques (IVF / ICSI) and egg donation.
The time of stay should be noted that it is indefinite. Also, general fertility treatments with frozen sperm have the same success rates as with fresh sperm.
