What is the specific process of pregnancy

1. Teste production sperm

Sperm is manufactured by testicular (testicular is located in the scrotum of pregnant men, one left and right), and there are many raw sperm tubes in the testicles.There are spermal sperm cells with sperm inner walls of sperm tubes. Spermocytes will be divided into primary sperm cells. They are divided into secondary sperm cells and finally become sperm cells.It takes about 90 days from sperm cells to sperm cells.

The testicles are constantly creating sperm, with about 30 million production in a day.Sperm, which has just been made by testicular, does not have the ability to fertilize eggs.The young sperm will be sent to the epididymis for two weeks, and it can become a sperm with fertilization after maturity.Mature sperm ejaculates through the vasia pipe and urethra.

2. Ovarian production of eggs

The eggs are oval and the size is like grapes, with two, which are on both sides of the uterus.They were formed when women were young, just like two "small gardens" in women, with many "seeds" hidden in it.As women grow up, "seeds" will slowly grow up. When "seeds" grow up and mature, they will leave this "small garden". When they reach another place -the fallopian tube, waiting for the arrival of sperm.

Normal childbearing age women usually mature and discharge on the ovarian on the left or right ovarian every month. When the eggs are discharged from the follicles, it usually takes 8-15 minutes.In the ovary cavity, and reach the connection point of the belly of the fallopian tube and the gorge, the eggs stay here and wait for the coming of sperm.

3. How long can the eggs survive

The survival time of the eggs is 1 to 2 days, and the strongest time of its fertilization ability is within 24 hours after ovulation, that is, the eggs entering the fallopian tube can be combined with fertilization of sperm and eggs within 24 hours. If sperm and eggs can be combined with fertilization.If you lose the chance of encounter at this stage, the egg will lose fertilization and die.

Sperm can survive for 2 to 3 days, so sexual life during ovulation is the easiest to conceive, and the farther the ovulation period, the smaller the chance of conception.5 days before the ovulation period and 4 days, a total of about 10 days belong to the concerted period, and other time is a relatively safe period.Women can once in the same room once a day during ovulation.

4. Discosit the tubes in the same room to send the sperm out of the sperm

The infusion pipe, as the name implies, is the pipeline of the sperm, one on the left and right, each with a total length of about 40 cm.Sperm passing tubes are transmitted from the accessory of the epididymis to the prostate and urethral channel. The vasal pipe and the function of semen can help sperm to enter women’s body.

If a male vasal tube is blocked, the sperm operation and exclusion occur, which can lead to infertility, which is the same reason that it is not unreasonable to female fallopian tubes.

5. The fallopian tube is the place where sperm and eggs meet

The fallopian tube is a long and curved pipeline. It is both sides of the uterus. The inner end is connected to the uterus. It is an important organ to pick up eggs, transport sperm, and send fertilized eggs to the uterine cavity.If the fallopian tube is blocked, the sperm and egg cannot enter the combination.

If the fertilized eggs are not moved into the uterus due to the lesions of the fallopian tube, they stay and develop in the fallopian tube or other parts, which is usually called ectopic pregnancy.

6. Combination sperm and eggs to form fertilized eggs

If the pregnancy couple seizures within a few days before and after ovulation, sperm and eggs may meet in the belly of the infusion pipe pot. At this time, a group of sperm surrounds the eggs. In the end, only one fastest and strongest sperm can meet the eggs.Creative kiss.

The most amazing thing is that when a sperm enters the eggs, the egg will immediately release a chemical to surround themselves, block other sperm outside, avoid stirring.A new cell is then formed, which is called fertilized eggs or pregnancy. This process is called fertilization.

If two or more eggs are discharged at the same time on both sides of the ovaries on both sides of the ovaries and combined with sperm, the twins and polycoplasma twins are born.

7. How long does it take to combine sperm and eggs

It takes 1 to 1.5 hours to discharge sperm and wait for the binding of the egg tube to the binding of the eggs.In the same room, men discharged 20 to 400 million sperm each time, however, most sperm discharged from the vagina with semen.Because the cervical canal mucus is alkaline, it is conducive to sperm activity. A small part of the sperm relies on the tail to move forward, and soon swims to the cervical canal, and the sperm releases protein soluble to dissolve the cervical mucus;Sperm movement.Sperm swim to the belly of the fallopian tube pot, where to wait with the egg binding.The fastest time for sperm to reach the fallopian tube is only a few minutes, 4 ~ 6 hours late, and generally 1 to 1.5 hours.

8. Enter the uterus slowly and get in bed

After the sperm enters the eggs, the sperm’s tail disappears, the head swells, and the combination of the eggs forms fertilization to form a fertilized egg containing 46 chromosomal cells.Among them, 23 of them came from the father and 23 from the mother.After several hours of changes, the cells began to copy DNA substances, and they were divided into two.

This fertilized egg slowly invades the uterine cavity until the movement of the tubal cilium and the peristalsis of the tube wall, until it is bed.This process takes 7 ~ 8 days.After the fertilized egg, it gradually develops into an embryo and an attached to the mother -placenta, fetal membrane, umbilical cord and amniotic fluid.The life journey of artifacts began.
