What are the physiological reasons for the elderly childbearing

With the development of society and the improvement of people's living standards, more and more women choose to marry later and have children later. Even when they are half aged Xu Niang, they still want to try to have children. However, women's physiological functions are limited. With the growth of age, women's fertility will gradually decline. So, what are the physiological reasons for the elderly childbearing?

1. The number and quality of eggs decline

When a woman is born, she already carries a fixed number of eggs, which gradually decrease with age. At the same time, with the growth of age, the quality of eggs will decline. Young women's eggs are usually healthy with normal chromosomes, so they are easy to conceive and give birth to healthy babies. However, the number and quality of eggs of the elderly women are reduced, which may lead to chromosomal abnormalities and increase the risk of infertility or fetal malformation.

In addition, aging will also lead to accelerated apoptosis of eggs, which will lead to fewer eggs being able to successfully fertilize and implant. This is one of the main reasons why it is difficult for elderly women to conceive.

2. Decreased uterine function

With the growth of age, women's uterine function will also decline. The endometrial thickness and blood supply decrease, reducing the chances of embryo implantation. In addition, the tension and elasticity of uterine muscles will also decrease, which may increase the risk of premature delivery, abortion and other pregnancy complications.

In addition, the quality and quantity of cervical mucus will also be reduced by age, which limits the ability of sperm to enter the uterus through the cervix. This is also a physiological reason why it is difficult for older women to conceive.

3. Changes in hormone levels

Women's hormone levels will change significantly before and after menopause. The decline of ovarian function and the reduction of ovarian hormone secretion lead to irregular menstruation and ovulation disorders, thus reducing the chance of pregnancy. In addition, changes in hormone levels may also lead to changes in the texture and thickness of the endometrium, affecting embryo implantation.

After menopause, the hormone levels in women's bodies will further decline, which means that even if they successfully conceive, they will also face higher risk of abortion and reduced chances of implantation.

4. Increased risk of pregnancy complications

Older women face a higher risk of pregnancy complications during pregnancy. For example, the risk of suffering from hypertension, gestational diabetes, pre eclampsia and other diseases is significantly increased. When an elderly woman is pregnant, the development of the fetus is closely related to the health of the mother, and poor health of the mother will increase the risk of fetal abnormalities.

In the case of elderly pregnancy, if pregnancy complications occur, doctors may need to take more interventions to protect the health of mothers and fetuses, which increases the risks and challenges of pregnancy.

summary

The physiological reasons for the elderly childbearing mainly include the decline in the number and quality of eggs, the decline in uterine function, changes in hormone levels, and the increased risk of pregnancy complications. These physiological changes make it more difficult for older women to conceive and face more risks of infertility and pregnancy complications. Therefore, when considering elder childbearing, women should conduct full consultation and evaluation as soon as possible, so as to better understand their own physiological conditions and make wise decisions.
