What is it?

The vitrification of ovules is a very recurrent procedure for women of reproductive age who wish to postpone their motherhood since it is a reality that over time fertility decreases considerably, in each menstrual cycle hundreds of oocytes are lost, after the age of 35, only the total ovarian reserve is available, however, not only does the quantity decrease, the quality of the oocytes is also affected as time passes and the chances of having a baby with a chromosomal problem increase year by year.

Due to these reasons, the best age for egg preservation is before the age of 35, when the quantity and quality of oocytes begin to decline.

The uncertainty that the future produces is a good reason to bet on vitrification or if the decision to be a mother or not has yet been made. 

Why should you do it?

As the woman ages, the number and quality of oocytes decrease. It is an option for all those women who for medical or personal reasons cannot or do not want to get pregnant immediately but who do contemplate it at some point in their life. If you are still not sure, you can still consider it as an option in case your opinion is different in the future. 

It is recommended to women who wish to postpone their motherhood, suffer from any disease, are still not sure of wanting children in the future, or must undergo treatment where their reproductive capacity may be affected, such as cancer that directly affects fertility.

The first step in the vitrification of ovules consists of ovarian stimulation so that a greater number of mature oocytes are produced. These must be extracted through a puncture, once they are in the laboratory they are protected against the low temperatures to which they will be exposed to different substances called cryoprotectants to prevent the cell membrane from breaking, that is why the vitrification of female gametes are performed quickly to avoid ice formation and are preserved in liquid nitrogen for as long as required. The number of oocytes to be frozen will depend on the ovarian response to the stimulation of each woman, it is estimated that about 80% of the preserved eggs can be used for fertility treatment. To achieve a pregnancy with preserved eggs it is necessary to use In Vitro FertilizationICSI or PICSI,.

Semen cryopreservation

What is it?

The semen cryopreservation is a technique used in assisted reproduction treatments that aim to preserve the fertilizing capacity of sperm regardless of the passage of time. Once sperm are in the environment, they lose mobility. It is a recommended option for those men who want to preserve their fertility due to some medical treatment that puts their reproductive capacity at risk, personal situation or due to the realization of a vasectomy, since if at any time they wanted to reverse it would be necessary a new surgical procedure, with this method it would not be necessary.

Why should you do it?

It allows preserving the fertility of the man without a time limit to be able to use it in the future through assisted reproduction techniques. The sperm will remain young and in optimal condition thanks to our cryoprotectants so that they can be used later.

Men are recommended to undergo treatments that can reduce or nullify their fertility (testicular surgery, prostate, vasectomy, chemotherapy, radiotherapy), progressive deterioration of the quality or quantity of sperm for a known or unknown cause.

Semen freezing consists at first in collecting the fresh ejaculation of the male, this is stored in small tubes, with the help of cryoprotectants cell damage is prevented and the sample is frozen and preserved in liquid nitrogen at a temperature of approximately -196 C °. The quality of the sample is decreased by a very low percentage at the time of freezing and thawing, during storage it remains intact, so the chances of using the semen and having a successful assisted reproduction treatment are very high, intrauterine insemination with donor semen or traditional In Vitro Fertilization traditional or ICSI with donated sperm has excellent success rates.
