Women prefer to give birth at a young age, however, for some, this process occurs in a later period. Scientists from Oxford told how long it is possible to postpone the birth of a child.

The average age of a woman who became a mother for the first time, as of 2017, was 30 years. According to statistics, until the 60s in the United States, girls gave birth to their first baby at the age of 21. Dagan Wells, professor of reproductive medicine, expressed his opinion on the deadlines for conceiving a child and carrying a fetus. One should take into account the constant and predominantly irreversible decrease in fertility in women after 35 years. In comparison, in men, the ability to conceive a child is weakened from the age of 45, at the same time this process is slowed down, which cannot be said about women. For most of the fairer sex, the ability to become pregnant ends eight years before menopause. At the same time, the ovarian reserve should be taken into account, since there is a certain number of follicles that can ensure the conception of the fetus.
It is necessary to measure the level of the hormone AMH in the woman's blood and determine the activity of the ovaries. The concentration of this hormone at 30-35 years old is two-thirds of the level of a 20-year-old girl, however, after 40 years it decreases to a quarter. The professor noted that physiologically, the vast majority of women become infertile at 45 years old.
