The chances of conceiving naturally over the age of 35

The chances of conceiving naturally over the age of 35

Women's childbearing age is limited. The probability of artificial insemination will drop sharply with age. The birth rate reaches a peak in the 20s. From the age of 32, the birth rate begins to decline, especially after the age of 35, the decline in the birth rate accelerates. By the age of 40, the birth rate has at least dropped by half, and the probability is only about 5%.

When a woman is born, there are about 1 million eggs in her body. By puberty, there are only about 300,000 to 500,000 eggs left. With the increase of age, the body's egg cell reserve will continue to decrease. By the age of 37, there are only about 25,000 eggs. Moreover, not every one of these eggs has the opportunity to mature and be released from the body. Only about 300 eggs will mature and be released during ovulation in a woman's lifetime, which means that the chances of a woman getting pregnant in her lifetime are only about 300 or less. For women, these 300 pregnancy opportunities are particularly precious.

In addition to the decrease in the number of eggs, eggs also become aging as women age. Especially after the age of 35, due to the continuous degeneration of the uterus and ovaries, women are more likely to suffer from endometriosis, uterine fibroids, reproductive hormone abnormalities and other problems, making it more difficult to get pregnant. Even if they get pregnant, the aging eggs are more likely to have chromosomal abnormalities, increasing the risk of miscarriage and congenital defects in the baby.

In addition, the age of the pregnant father will also affect the probability of pregnancy. Although men's sperm is renewed every three months and the age of sperm is only three months, which is relatively young and attractive, studies have found that once men reach the age of 45, the attractiveness of their sperm will decrease significantly and the deformity rate will increase, resulting in a lower fertility rate.

Therefore, the age of prospective parents, especially the age of pregnant mother, is an important factor affecting pregnancy. The older they are, the lower the chance of pregnancy.
