"11 Secrets of Sperm, Know 3 Count You Great! 》
A friend said that he also wanted to see the secret of eggs
Well! The egg sister is shy
After thousands of calls, it is finally here!
First, what does a shy egg look like?
She has
Beaded body
The crown radiates on the top of the head and is draped in a transparent band
Slim
Ball sister one.
She's the biggest cell in your body!
It carries the great responsibility of reproduction and destiny, and is destined to attract everyone's attention.
Second, the little secrets of the egg sister
Secret 1: How is the egg sister formed?
The egg sister's home is in a 15-30 mm oval follicle.
When she was still in the body of the mother's oocyte, it was just a chromosome.
As the years passed, when the little fairy reached the age of 12-15, the oocytes in the ovaries could no longer settle down and began to divide, divide, divide.
Stimulated by gonadotropins, every month an egg sister grows, matures, leaves the ovary and runs to the fallopian tubes, where she waits quietly for her sperm brother [1].
The first time an egg leaves the follicle with menstrual blood, this is the "menarche" that makes every little fairy panic.
Don't be afraid, congratulations to the little fairies on growing up, which shows that your reproductive organs are mature.
First love is beautiful, but you can't "steal the forbidden fruit" before the age of 18. Your vulva and vagina are still very delicate and prone to tearing and bleeding. You are not rich enough in knowledge, unexpected early pregnancy miscarriage, hurt not only the body, but also a gap that youth cannot overcome.
Like is wanton, love is restraint.
Tips:
"Menarche" is earlier than 10 years old or later than 15 years old, and you have to go to the endocrinology department or gynecology department of the hospital for examination.
The little fairies also need to master more physiological knowledge to protect their bodies.
Secret 2: After the egg sister leaves home, life is very short
After the egg sister leaves her home, her life is only 1-2 days, and in the first 15-18 hours, the chance of union with the sperm brother is the greatest, after which the chance of them meeting and falling in love will become smaller and smaller.
The sperm brother who reaches the small main fallopian tube has a life of 2-3 days, leaving a very short time for both parties to meet [2].
If you want to successfully get pregnant, you must calculate the time and strike accurately and quickly!
For the little fairies with regular menstrual periods, you can learn the following method of calculating the ovulation period:
Ovulation period calculation method, please study carefully:
Let's start by understanding 2 concepts:
Ovulation period: two weeks before menstruation;
Menstrual cycle: The time between two great aunts is called the menstrual cycle. The general standard is 28 days, of course, 21 days to 35 days are normal.
For example, a chestnut: Assuming that the time of the two great aunts is March 1 and March 30, then the menstrual cycle is 30 days, and the next time you come to the great aunt is April 29.
Calculate the ovulation period: from the first day of the next menstrual period, subtracting 14 days is the ovulation day, so the next ovulation day is April 15, 5 days before ovulation and 4 days after ovulation are ovulation periods, so the next ovulation day is April 10 - April 19.
If the aunt is irregular, you can use ovulation test strips or go to the hospital for ultrasound monitoring.
Secret 3: Keep the nutrition balanced and healthy, and the figure of the egg sister can reach the standard
Normally, her diameter is between 18 and 25 mm, but if it is less than 17 mm in diameter, it is not easy to get pregnant [3,4].
If the little fairies always stay up late, the hormones in the body are abnormal, or they lose weight unscientifically in order to slim out, resulting in malnutrition, the follicles of the "small house" where the eggs are developed will not grow, and the natural figure of the egg sister will become shorter.
Secret 4: The egg sister's large sisterhood, the number of which decreases as the years go by
When the little fairies are born, there are usually 2 million follicles, and when they reach youth, there are only about 300,000 left, and finally, they can mature and drain, and only 400-500 are encountered with sperm brothers[5], and those who insist on the "decisive battle" are the female Haojie Wow!
When the little fairies are 12-18 years old, the egg sisters are in good health; at the age of 20-35, the egg sisters are still in good health, and the womb is mature, which is the golden time to conceive the baby; after 35 years old, the egg sisters' bodies will be weak. But you don't need to be anxious, maintain good living habits, a positive and optimistic attitude, fully prepared, and will also give birth to a healthy baby.

Secret 5: How the egg sister and the sperm brother met
The egg sister is in love passive type, every month out of the follicle of one side of the ovary, picked up by the tubal umbrella, reached the fallopian tube, and then stayed here, silly waiting for the sperm brother.
Adult males ejaculate hundreds of millions of sperm at a time, and about 200 sperm reach the fallopian tubes. Sperm brothers need to pass through the pellucida of the egg in order to come to the egg's sister to achieve fertilization, and combine with the oocytes to form a fertilized egg.
When the little fairies usually have a pain in the lower abdomen and an increase in pain when they come to the big aunt, hurry up and check the fallopian tubes.
If there is inflammation, the umbrella end will not be able to pick up the egg sister, and it may not meet the sperm brother.
Secret 6: The egg sister can navigate for the sperm brother
The egg sister is covered with a pellucida band with specific sperm receptors on it that tell the sperm brother where she is. As soon as the first sperm brother comes in and combines with her to form a fertilized egg, the transparent membrane morphology will immediately change[6], which can be understood as closing the door and changing the lock, so that other sperm brothers cannot enter.
Secret 7: Didn't wait until where the sperm brother's egg sister went?
If there is no love with the sperm brother, the egg sister will not continue to grow after reaching the uterus, she will lose vitality, either absorbed by the body, or "shedding" from the uterine wall, with the uterine lining, secretions, necrotic cells, etc. excreted from the body, becoming part of the great aunt.
Third, the ovaries are healthy, and the eggs can be healthy
Dear little fairies, be sober: the ovarian maintenance of the beauty salon is not reliable! The ovaries are located deep in the pelvis, and massage alone cannot be pressed here. Secondly, the "essential oil" of the beauty salon only stays on the surface of the skin, and don't be fooled by the mouth of the merchant anymore.
The following three points are the most important:
1. Ensure the temperature around the ovaries
Ovarian function declines when the body is stimulated by cold, which affects the secretion of estrogen and progesterone. When hormone secretion is disordered, the quality of the eggs produced by the ovaries is not good, so everyone should pay attention to keeping warm [7]. In the summer, it is less directly blown on the air conditioner, and in the winter, when going out, you have to wrap yourself thicker.
2. Smoking or passive smoking is harmful
Cigarette smoke contains a large number of harmful components such as nicotine and polycyclic aromatic hydrocarbons, which can affect ovarian function. Studies have shown that secondhand smoke also harms the reproductive function of fairy fairies, resulting in a decrease in the number of egg cells and abnormalities in the chromosomes in the egg [8].
3. Mental health is important!
Mental emotions are closely related to the occurrence of premature ovarian failure.
Under the long-term emotional distress and stimulation of emotional instability, depression, anxiety and other adverse emotions, the central nervous system and the hypothalamic-pituitary-ovarian axis are dysfunctional, and the abnormal secretion of follicle-luteinizing hormone will affect ovulation function [9] and affect the birth of the egg sister.
Extracurricular knowledge about eggs:
Is egg freezing safe?
Ovulation induction and egg retrieval are relatively safe treatment and procedure for women themselves, and the risks involved include ovarian hyperstimulation syndrome and some surgical complications.
Since the birth of the first frozen egg baby in 1986, more and more IVF babies have been born around the world, but there is no exact data on whether frozen eggs will affect the health of children.
