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?

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.
