For the first time, Spain exceeded 40,000 babies born using these techniques, according to the 2021 registry of the Spanish Fertility Society. Age plays a key role in women's fertility: as it increases, the chances of getting pregnant decrease, especially after 35.
Spain is the country of older mothers, since one in 10 births in 2021 were to a woman who had already turned 40, the highest proportion in the European Union. On average, women in 2022 had children at 32.61 years old.
