The first thing to know is that the reproductive potential of healthy women decreases physiologically with age, especially after 35-37 years of age. If at 25 years of age fertility can be 80%, at 30 it is 70% and at 35 it is 60%, at 37 it drops to 50% and at 42 it reaches 36%.
If you do not plan to, cannot or do not want to become a mother before the age of 35, you should know what fertility preservation consists of and evaluate it as a viable option to become a mother when you decide to do so. If you do not take it into account, it is possible that your body will not respond as expected.
Fertility preservation consists of freezing the eggs by vitrification. This technique allows obtaining higher survival rates in the freezing and thawing process, achieving that 85-98% of the vitrified eggs successfully pass the process. It also avoids injury to the egg thanks to the rapid cooling and cryoprotectants used.
New opportunities
The vitrification technique is also used for people who have undergone cancer treatment. Thanks to the high rates of overcoming many cancers, the need has arisen to recover the reproductive desire of these people after the possible loss of fertility during chemo and/or radiotherapy treatments. Thus, either by cryopreservation of oocytes or spermatozoa before cancer treatments, it will be possible to maintain initial fertility, offering a better quality of life.
