How many weeks does the reproductive organs of the fetus mature?

A baby is created and grows slowly in our belly until delivery. As a mother, it is a very difficult but very happy thing. Every day's changes make us very excited. We start to imagine how he lives in our belly. Then, in how many weeks does the fetus's organs develop completely? Today, I will give you a brief introduction.

How many weeks does it take for the fetus' organs to grow and develop completely?

1. Generally speaking, at 12 weeks of pregnancy, the fetus's reproductive organs begin to grow and develop. If there are any deformities, they may be manifested, and the head becomes thicker and more complete. The reproductive organs and urethra of the fetus begin to form in the 8th week of pregnancy and are completely formed in the 15th week. When a four-dimensional B-ultrasound examination is performed in the 24th week, almost all organs of the fetus have developed well.

2. The third to sixth months of pregnancy is the first stage of rapid reproduction of brain nerves, which is called the "rapid brain growth period." Mainly due to the expansion of brain nerve volume and the growth of sympathetic nerves, the brain weight continues to increase. The second stage is from July to September of pregnancy, during which the proliferation of cells and central nervous system cells and the expansion of dendrites are supported, so that the established neurons develop into neurotransmitter connections between neurons and cells to transmit the excitation desire of neurons. For human intelligence, the increase of dendrites in brain neurons is far more important than the increase of the number of cells.

Factors that affect the baby's development during pregnancy

1. Nutritional factors: Poor diet during pregnancy will have a series of effects on pregnant mothers and fetuses, causing delayed fetal language development and even deformities.

2. Job factors refer to the harm to the baby's development caused by the working environment and various factors that pregnant women are exposed to during the work process. For example, the fetal nervous system is more sensitive to lead, which can cause defects in the fetal brain and nervous system, making pregnant women more likely to be poisoned.

3. Mentality Factors

Keeping your emotions stable and feeling happy during pregnancy will have a good effect on the healthy growth and development of the fetus.

Creating a child is a very complicated process, and there are many things that expectant parents need to learn. After all, the creation of life is a great and sacred thing. When we decide to have a child, we need to maintain physical health and emotional comfort, so that our baby will be a healthy and happy baby from the beginning of pregnancy!
