With 20 years, the chance of conceiving is 25 percent; with 40 years it is reduced to five percent

Today, women choose to be a mother at increasingly advanced ages. Almost 90 percent of Spanish women under 30 are still not mothers, largely due to work, economic and lack of family reconciliation.

The average age to be a mother in Spain is 31.9 years, the highest in the European Union. It is the age at which women have their first birth today, compared to 24 to 26 years of the 1970s.

The best age to conceive

As you know, women are born with a certain number of oocytes, around one million, which are decreasing as we turn years and with them the chances of pregnancy.

The ovules are not renewed, but we have a specific ovarian reserve that varies from one woman to another, and hence the importance of the mother's age when conceiving.

According to WHO, the safest age to conceive is situated between 20 and 24 years old. In biological terms, 25 years is the best age to be a mother.

After 27 years of age, fertility begins to decline, but it is after 35 years when the ovarian reserve worsens considerably.

With age, the ovules contain more and more chromosomal alterations that hinder pregnancy and increase the probability of abortion and / or genetic diseases.

Researchers at the University of St. Andrews confirm that after 35 years, a woman's ovarian reserve is almost 10 percent of the total. And at 40, the woman barely has quality ovules without reproductive and / or chromosomal failures, being her ovarian reserve of three percent.

From that age, the ovarian reserve continues to decrease until it is completely depleted, approximately between 45 and 55 years.
