Science of IVF: Follicular development is delayed, and there are several leading factors!

On the road to IVF, every small detail can become the key to success or failure. Among them, the development status of follicles is one of the important factors related to the success of IVF. However, many expectant mothers are in test tubes

During the process of promoting ovulation, we will encounter the problem of delayed follicular development. What is going on? Today, we will reveal the "behind-the-scenes" of follicular development delay.

The maturation process of follicles usually takes about nine months. During this long preparation period, the shape of the follicle remains mostly stable until it enters the end stage of its development-the follicular phase of the menstrual cycle. At this time, the follicle experiences

The transition from pre-antral follicle to pre-ovulatory follicle also increases in diameter from a tiny few tens of microns to about 15 mm. Typically, follicles reach maturity during ovulation and range in size from 18 mm to 25 mm. However, some follicles

The path togrowth is not smooth, and it is always difficult to reach this threshold of maturity.

What are the causes of delayed follicular development?

During the treatment of IVF, the development status of follicles is a crucial factor. Healthy follicles can produce high-quality eggs, but delayed follicular development is a cause of

A commonproblem that may lead to poor egg quality and affect pregnancy results. Here are some reasons that may lead to delayed follicular development

1. Age factor: Time is a double-edged sword

Time cannot spare anyone, and women's fertility will gradually decline with age. In the field of IVF, age is a factor that cannot be ignored. As a woman ages, the quality of the egg will gradually decline, resulting in

Causes delayed follicular development. Therefore, for women with childbearing needs, it is wise to plan early and act early.

2. Endocrine disorders: Imbalance of hormone levels

Hormone levels in women play a crucial role in the development of follicles. If hormone levels are unbalanced, it can lead to delayed follicular development. For example, diseases such as polycystic ovary syndrome and premature ovarian failure may cause hormone levels

Imbalance, thus affecting the development of follicles. In addition, bad living habits such as staying up late for a long time and overwork may also lead to endocrine disorders and affect the development of follicles.

3. Drug factors: Ovulation promotion regimen is not suitable

During the process of promoting ovulation in vitro, the IVF fertility assistant will formulate a personalized ovulation promotion plan based on the patient's specific conditions. However, if the ovulation promotion regimen is not suitable for the patient, or the patient is less sensitive to the drug, it may lead to oocytes

vesicular development is delayed. At this time, the IVF will adjust the medication plan, dose and type according to the patient's specific conditions in order to improve the development of follicles.

Chromosomal abnormalities are an important cause of embryonic dysplasia. If both or one of the spouses have chromosomal abnormalities, it may lead to poor development of the embryo, resulting in delayed follicular development. Therefore, in

It is very necessary to perform chromosome examination before IVF babies.

5. Environmental factors: impact of lifestyle

In addition to the above factors, environmental factors may also affect the development of follicles. For example, long-term living in a heavily polluted environment and long-term exposure to harmful substances may have adverse effects on the development of follicles. Therefore, guarantee

It is also very important to maintain a good living environment and avoid contact with harmful substances.

6. Mental factors: the impact of emotional stress

During the process of IVF, many expectant mothers face tremendous psychological pressure. Long-term negative emotions such as mental stress and anxiety can affect the body's endocrine system, thereby affecting the development of follicles. Therefore, keep it good

Itis also very important to have a mental attitude and actively face various challenges in the process of IVF.

After understanding these causes that may lead to delayed follicular development, patients and IVF can work together to develop a more personalized treatment plan. At the same time, patients should also Pay attention to maintaining good health

Live habits, reduce the impact of environmental factors, and actively face various challenges during the treatment process.

Follicular development delay anddoing IVF canbe grasped from many aspects

1. Adopt natural medicines

During the ovulation induction process, IVFwilluse natural drugs, which have no side effects and will not produce residues in the human body. It can be completely metabolized in only one menstrual cycle.

2. Regularly detect drug reactions

On the second day of menstruation, estrogen levels, ovarian status and presence of abnormalities will be evaluated through blood tests and negative ultrasound examinations. If it is confirmed that the conditions are appropriate, start using the drug and officially start the elimination cycle. During the medication period, in vitro pregnancy

The divisionrequires women to have regularB examinations to observe follicular development and adjust the dose of the drug based on hormone changes. When the follicle diameter reaches the standard, stop the medication immediately.

n 3. Painless egg retrieval under general anesthesia

When the follicles reach the standard size (e.g. 1-2 follicles reach 18mm, 2-3 follicles reach 17mm), theIVF willinject the woman with an oocyte breaking needle (HCG/Lupron), andthe eggs will be retrieved 36 hours later. The anesthesiologist selects each

Calculate the anesthetic dose based on the woman's individual situation to ensure that the entire egg retrieval process is painless and safe. Under theguidance of B ultrasound, fine needle was used to suck follicular fluid from vagina to ovary, and mature eggs were quickly obtained. The whole egg retrieval process takes only about 10 minutes

Efficient and secure.

In general, foods rich in protein, vitamins and trace elements can significantly promote the maturation of follicles. Taking more of the following foods will help the rapid and healthy development of follicles

1. Foods rich in vitamins such as leeks, kiwis, fresh dates, and spinach can effectively promote the normal development of eggs. Among them, fresh dates also have the effect of replenishing qi and blood, while the volatile oil and cellulose in leeks help detoxify.

2. Eggs, dairy products, lean meat and other foods rich in high-quality protein. For example, eggs can promote follicular development and have health care functions; the ingredients in milk and lean meat have a positive effect on egg growth.

3. Aquatic foods such as marine fish, seaweed, water fish, and clams are not only rich in unsaturated fatty acids, but also help enhance immunity and block the reaction of cigarettes. It can also promote the excretion of radioactive materials from the body. Especially water fish are not sensitive to follicular development

All have curative effects, while clams can promote follicular development.

4. Animal blood products, soy products, nuts, grains, etc. are also rich in nutrients. Animal blood products can react with harmful substances and improve egg quality; soy products and grains can supplement estrogen; and nuts can provide the body with what volunteers need for development.

Trace elements.

5. In addition to a balanced diet, the healthy development of follicles also requires appropriate exercise and regular work and rest schedules. Reasonable exercise and rest help regulate endocrine and promote normal growth of follicles.
