Women need egg cells during pregnancy, which is the process of sperm egg fusion. Our human body cells are divided into general somatic cells and germ cells, and there is still a big difference. Firstly, in terms of price, germ cells are still very large. Below, we will explain the differences between egg cells and somatic cells.
1、 The difference between oocytes and somatic cells
1. Somatic cells refer to cells that do not perform reproductive functions, while germ cells are cells that perform reproductive functions and can undergo meiosis. Spermatogonia are somatic cells in terms of their production, but they are also quite unique. Spermatogonia can also form germ cells (also known as germ cells) through meiosis.
2. The number of chromosomes in germ cells is half that of somatic cells. The shape of germ cells is specialized, such as the spindle shaped tail structure of sperm, which facilitates sperm motility and fertilization, and the large volume and abundant yolk of egg cells, which facilitate cell division before implantation after shock.
2、 The process of egg cell production
1. Eggs are produced by what we commonly refer to as the female gonads - ovaries, with a diameter of approximately 0.1mm. The main function of the ovaries, in addition to secreting essential sex hormones for women, is to produce eggs. Girls have already formed the embryonic form of their ovaries around 3-6 weeks of gestation. Millions of oocytes have already formed in the ovaries, but after childhood and adolescence, there are only over 100000 oocytes left in adulthood. The oocyte is wrapped in the primordial follicle, and under the influence of sex hormones, only one primordial follicle matures per month. Mature eggs are then released from the ovary into the abdominal cavity.
2. Overall, only one egg cell develops and matures during each menstrual cycle. In this way, from menarche to menopause around the age of 45, a woman has over 500 mature oocytes that can develop throughout her life. During the growth process of follicles, their volume gradually increases, and their fluid gradually increases. They also move from the inside of the ovary to the surface of the ovary, and finally protrude from the ovarian capsule.
3. After being discharged, an egg cell can survive for about 48 hours, waiting to meet and combine with sperm during this 48 hour period. If the egg cannot meet the sperm to form a fertilized egg due to various reasons after being released, it will naturally die 48-72 hours later. To lose this opportunity for fertilization, one must wait until one month later for another egg to mature and be released, repeating the same process.
The above is about the difference between egg cells and somatic cells, as well as the formation process of egg cells. The biggest difference is that one is a normal cell and the other is a reproductive cell. Women need egg cells for pregnancy, and there are still many egg cells in the female body. However, there are not many that truly mature. Some women have problems with their fallopian tubes and cannot be discharged.
