The Vistahermosa Reproduction Unit preserves the quality of ovules and sperm intact so you can decide the right moment to start a family

If a woman wants to be a mother but decides to delay her motherhood due to personal, work or economic circumstances, she must freeze her eggs at a fertile age, between 25 and 35 years old. Likewise, this procedure is also recommended in certain medical circumstances, such as young patients diagnosed with cancer, autoimmune diseases, bone marrow transplants or endometriosis, whose treatments threaten their fertility. Other cases are women and men who do not have a partner of fertile age but wish to be mothers and fathers in the future.

The freezing of gametes is the most advanced technique to preserve motherhood with guarantees, preserving all the quality of ovules and sperm. In the case of ovules, the procedure is similar to an in vitro fertilization.

It consists of performing an ovarian stimulation with the aim of producing several ovules in the same ovulation. These ovules are extracted through a follicular puncture and are vitrified, that is, they are frozen at an ultra-fast speed with cryoprotective substances, passing from a culture temperature of 37º to a cryopreservation temperature of -196º, preserving in liquid nitrogen all the as long as desired and keeping the cells intact for later use.

The main advantage of this process compared to traditional freezing is that the rapidity of freezing prevents the formation of ice crystals that can damage the ovule, obtaining unbeatable clinical results that are around 97%, similar to fresh oocytes. However, slow freezing works perfectly with sperm, since being very small cells with little volume can not form crystals that can harm their internal structure.

This revolutionary advance of Reproductive Medicine today is possible to decide when is the right time to start a family. “Research and high technology respond to the problems of infertility that present society presents,” says José López Gálvez, director of the Vistahermosa Reproduction Unit.

According to the specialist “we must take into account that after 35 years fertility decreases, and after 40, 75% of the ovules have some genetic alteration, which increases the probability of abortion by 40%. Similarly, semen quality has fallen by 40% compared to 10 years ago, both in concentration and mobility. That is why it is essential to know the alternatives that exist today and that allow a woman to use her own ovules, frozen in full fertile age, to be a mother in advanced age, with all the guarantees that her gametes are in perfect condition with the preservation of same quality. “
