Many women still have misunderstandings about fertility, thinking that they can wait when they are young and have children as soon as they ovulate.

So when I was young, I just smoked, drank, had boyfriends, and played as crazy as I wanted, hoping to enjoy my youth to the fullest.

As everyone knows, women's fertility varies greatly among individuals. The aging of egg cells does not match a person's biological age. Some women may no longer have fertility by the age of 35.

Older age not only reduces fertility but also increases the risk of pregnancy.

Although human assisted reproduction technology can help some couples who are unable to conceive to have a baby as they wish, the possibility of chromosomal abnormalities in their offspring is very high.

Especially after the age of 40, the probability of chromosomal abnormalities in their offspring is more than 1/100, which means that one in 100 mothers may give birth to a fetus with chromosomal abnormalities, such as Down syndrome.

They are also common "sugar babies". You can tell by the width of their eyes that they all look the same.

Therefore, women who want to have children should complete the important task of pregnancy during the best fertile period of 25 to 29 years old.

Chen Qi nodded at several young doctors present:

"Hey, did you guys listen? Yu Shanshan, I heard that you rejected all the blind dates that everyone introduced to you. This is not okay. A woman's career is important, and her family is also important. Otherwise, you look at Dr. Tao and you are so young.

If you want to do in vitro fertilization, you can't say whether it will be successful or not."

Everyone chuckled again.

Yu Shanshan was not afraid of Chen Qi and retorted:

"Dean, the main reason is that there are more and more patients now, so many that we can't even guarantee days off. How do you ask me to fall in love and find a partner? It's all your fault, the dean."

Since Chen Qi became the president, the business growth of Yuezhong Hospital has doubled every year. The income of medical staff has grown rapidly, but the workload is indeed very heavy.

Chen Qi was not angry and comforted:

"Don't worry, don't worry. I've already recruited 300 college students this year. You can breathe a sigh of relief when these people come back for further studies. I will continue to expand enrollment next year and make sure that no one becomes a medical migrant worker."

At this time, Professor Ding interrupted with a smile:

"Dean Chen, most of what you said about implant medicine is very new. Not to mention that they haven't heard of it, even I haven't heard of it. So if you don't stop, you can give everyone some information.

Let’s take class.”

Dean Chen hasn't had a class for a long time. His previous classes were all about surgery and rarely involved internal medicine and gynecology.

But the old employees of the People's Hospital all know that Director Chen either doesn't give lectures, but what he lectures are groundbreaking contents, which are of great clinical help. Every time he gave lectures in the past, the conference room was always full.

"Okay, since you want to listen, I will talk about it. The main content of the talk is about the cases of elderly women like Teacher Du Yafang. If the in vitro fertilization of these elderly women is done well, then the in vitro fertilization of young girls will not be a problem at all.

The first thing to talk about is the factors that affect the success of IVF, such as age, uterine environment, embryo quality, etc.

The first one is age. As I said before, this is one of the most important factors affecting the success rate of IVF.

Because as age increases, women's ovaries will gradually age and their functions will gradually decline, and the quality of men's gold will also decline significantly.

Therefore, the optimal age for IVF should be no more than 35 years old, otherwise miscarriage or premature birth may easily occur due to poor physical function.

The second factor is the environment of the uterus,

After the embryo is transplanted into the uterus, if the uterine environment is not good, such as endometritis, endometrial polyps, endometrial cancer and other lesions, it will change the uterine environment and easily affect embryonic development, thus

Cause in vitro fertilization to fail.

The third is embryo quality.

If the gold or embryo you choose has congenital abnormalities, such as an abnormal number of chromosomes or a missing chromosome structure, the survival rate of the embryo will be greatly affected.

Once the quality of the embryos is poor, it is easy for the embryos to stop fertilizing after embryo transfer.

In order to improve the success rate of IVF, both couples need to conduct systematic and comprehensive pre-pregnancy screening in advance, especially genetic tests, and try to eliminate adverse factors as much as possible before proceeding with IVF, which will help increase the success rate."

Yu Shanshan raised her hand and asked:

"Dean Chen, you said that the aging of the body is mainly due to ovarian factors. How do you understand it specifically?"

Chen Qi nodded and drew an anatomy diagram on the paper:

“The ovary is like a woman’s reproductive bank, and the wealth reserve of the egg follicle pool can be divided into two parts: the original pool (resting primordial egg follicle pool) and the dynamic pool (growing egg follicle pool).

This is like the deposits in the bank and the cash in circulation. The primordial follicles in the original pool are activated and become growing follicles and enter the dynamic pool. However, only one follicle in the menstrual cycle can be advantageously selected.

discharge.

Since birth, there are approximately 1 to 2 million primordial follicles. As the only form of follicle reserve, they naturally decline and die every day.

After the age of 35, the reserve capacity of the ovaries decreases, and the number of inferior follicles also increases.

After the age of 40, the ovarian follicles atresia accelerate and a "stick-breaking" phenomenon occurs, which is like a sudden steep slope on the way down the mountain.

So what is the mechanism that regulates reproductive capacity? Speaking of which, please remember that Professor Ding, Director Xu, and others must pay attention to this key knowledge. What are the factors that regulate reproductive capacity?

This point is still controversial and is still under research. You can set up a research group. This is another international paper.

Let me remind you first that the hypothalamic-pituitary-ovarian axis regulates the process of female reproductive aging through a classic feedback pathway. This is the most recent Mayo study that I am aware of.

I hope you can demonstrate this scientific research in advance through Teacher Du Yafang’s case, and if you cut off Humeo, then that’s your skill.”

"Wow, Dean Chen, you are so good at being a traitor~~~"

The doctors at the Implantation Center all applauded enthusiastically, because Director Chen gave them another big gift.

In the past, working in their own departments, these doctors had almost no exposure to good topics, and it was even more difficult to write papers.

But after I arrived at the Implantation Center, I felt like I couldn’t finish the paper. I couldn’t finish it at all. It turned out that there were too many topics, which was a kind of happy worry.

Only Chen Qi himself knew that this "Hypothalamic-Pituitary-Ovarian Axis" theory had to wait until 2004 to be published by relevant experts. It is still blank at present, and it is nothing like the Mayo Clinic.

Therefore, following a cheating leader like Chen Qi, being a subordinate is so happy.

After careful inspection, on the third day, the Shengzhi Medical Center found out clearly that the main problem between Dr. Tao Peiliang and Teacher Du Yafang was with the woman.

Although the male's tadpole is not energetic enough, it is still more than enough to give birth.

In addition to bilateral L-tube obstruction, Teacher Du also found uterine endometriosis lesions and pelvic adhesions in the pelvis.

Not only is he sick, Teacher Du’s ovarian reserve function AMH value is only 0.68ng/ml, which means that the key “ovarian” is difficult to mature and discharge normally.

But this is the key to in vitro fertilization. You must have healthy and sufficient numbers of "luans".

Director Xu Anqin felt particularly uncomfortable after receiving this report card. She could feel how much her old colleague longed to have a child of his own.

Moreover, what happened in the Tao family was a major gossip. In fact, it spread to the hospital very quickly, which was actually quite irritating.

Tao Peiliang is also a doctor and can understand the results. After receiving the examination form, he also sighed:

"Well, it seems that it is fate. When my wife and I worked up the courage to do in vitro fertilization, God no longer gave us the chance."

Professor Ding sat there and kept thinking, and suddenly she thought of a treatment method she had come across when she was a visiting scholar in Xiangjiang:

"No, actually there is no way. There is a latest drug abroad that can induce ovulation."

"What medicine?" everyone asked in unison.

"Injectable chorionic gonadotropin shot!"

"Chormonal gonadotropin injection? I've never heard of it. Which pharmaceutical factory in China produces it?"

Facing the confused colleagues, Professor Ding quickly explained:

"This drug is not currently available in China. It was recently developed in the United States. It is made from chorionic gonadotropin extracted from the urine of pregnant women or artificial abortion products."

Many doctors were a little surprised: "Wow, extracted from urine? This, this is too disgusting. Isn't it just like the 'Ren Zhong Huang' in traditional Chinese medicine?"

"Then you are wrong. This medicine has a very wide range of uses and its effects are very obvious.

For example, it can be used to treat prepubertal cryptohypertension, male infertility caused by hypopituitarism, female anovulatory infertility, in vitro fertilization, luteal insufficiency, functional uterine bleeding, and pregnancy.

Early threatened abortion, habitual abortion, etc.”

"Wow, it's so amazing..."

In 1990, there was almost no gynecological or infertility medicine in China, and most of them were traditional Chinese medicine.

In addition, at this time, China is carrying out very strict family planning. What we are thinking about is how to have fewer children. How can we encourage childbirth?

Domestic attention to implantable medicine did not begin until 2005, and only entered the fast lane in 2010.

No matter how much the media brags about it later, in fact our country is far behind in the field of implantable medicine, such as genetics. Alas, I can’t say more. If I say too much, I will say that the author is providing negative energy.

Of course, advertising is always far ahead. There are small infertility advertisements on those telephone poles and street corners...

Therefore, in the 1980s and 1990s, domestic doctors did not have access to internationally advanced drugs, advanced treatment methods and equipment, and they lacked too much in terms of cognition.

This is also the purpose of Chen Qi's insistence on recruiting several professors from Haidong Medical University.
