Test tube baby puzzle: Can I still do test tube baby without ovulation?

On the road of pursuing and nurturing their dreams, every couple may encounter various challenges and doubts. Among them, ovulation may be one of the topics that many women care about most. When faced with the dilemma of not ovulation, many women can

Ican feel confused and hopeless, and I can't help but ask: Can I still have a test-tube baby without ovulation? Today, we will discuss this issue together to solve the doubts in your heart.

What is ovulation disorder?

tNormal ovulation requiresthe normal function of the complete hypothalamic-pituitary-ovarian gonadal axis. Dysfunction of any link or organic disease can cause temporary or long-term ovarian dysfunction, leading to abnormal ovulation

Often. Causes of ovulation disorders include

1. Ovarian lesions: One of the main causes of ovulation disorders, including congenital ovarian dysplasia, polycystic ovary syndrome, premature aging of ovarian function, ovarian tumors, etc. For example, most patients with polycystic ovary syndrome will express

Currently suffering from amenorrhea or oligomenorrhea, long-term anovulation, excessive androgens, and non-cyclical fluctuations in estrogen.

2. Hypothalamic-pituitary-ovarian axis dysfunction: This is usually due to negative emotions such as tension, anxiety, anger, and sadness, which leads to brain dysfunction and causes non-ovulation or abnormal ovulation.

3. Systemic diseases: Diseases such as severe malnutrition and hyperthyroidism can cause ovulation disorders.

4. Drug effects: Certain drugs, such as long-acting steroid injection contraceptives, disrupt the interaction between the brain and the ovaries, inhibit ovulation and prevent pregnancy.

What are the symptoms of ovulation disorder?

Common clinical manifestations of ovulation disorders include completely irregular uterine bleeding, amenorrhea, and infertility.

Irregular uterine bleeding is common in adolescent women, and the bleeding interval can be long or short, ranging from a few days to months, or evenmore than a year. The duration of bleeding can also be long or short. When the amount of bleeding is small, only dripping bleeding can occur, and when the amount of bleeding is long, there can be

Large blood clot.

Amenorrhea is divided into two types: girlswho have not had menstruation at the age of 18 are called primary amenorrhea; those who have had menstruation but stopped menstruation for more than 6 menstrual cycles are called secondary amenorrhea.

Infertility means that you do not become pregnant after 12 months of normal sex without taking contraceptive measures. Ovulatory disorders or sporadic ovulation account for about 40% of female infertility factors.

Ovulation disorder causes infertility

n Chronic ovulation disorder caused by ovulation disorder is a common manifestation of many endocrine diseases, accounting for20% to 25% of women. In 1993, the World Health Organization (WHO) formulated classification standards for anovulation, which are divided into three categories. W

Type HO (low gonadotropic anovulation), WHO Type II (normal gonadotropic anovulation), WHO Type III (high gonadotropic anovulation).

WHO Type I: The main manifestations are hypothalamic amenorrhea (stress, weight loss, exercise, anorexia nervosa and others), Kallmann syndrome (abnormal migration of gonadotropin-releasing hormone precursor cells) and gonadotropin defects.

WHO Type II: Ovarian dysfunction mainly manifested by normal gonadotropin, accompanied by varying degrees of anovulation or oligomenorrhea. For example, polycystic ovary syndrome (PCOS)

WHO Type III: The main manifestation is hypergonadotropic hypogonadism, including premature ovarian failure and gonadal dysplasia (ovarian resistance).

So, how can test-tube babies help women successfully ovulate and have a smooth pregnancy?

Inorder to help women successfully ovulate and have a smooth pregnancy, in vitro fertilization technology (IVF) does not mainly solve the ovulation problem directly, but uses a series of assisted reproductive technologies to allow women to avoid ovulate naturally or have poor egg quality

In cases, you can also have a chance to achieve pregnancy. Here is a detailed explanation of how IVF technology can help women successfully ovulate and have a smooth pregnancy

Before inducing ovulation, IVFwill guide women to take drugs to downtune. This is mainly because women have a dominant follicle among several follicles every month. By absorbing other follicles in the ovary, they can grow, resulting in other eggs

vesicle apoptosis. Therefore, inhibiting the growth of dominant follicles can enable multiple follicles to develop evenly and synchronously and obtain more mature eggs when promoting oocyte retrieval. Because these eggs come from follicles that are about to disappear and die, they will not pass

Consumption of the number of eggs will not have any effect on the body.

Before the IVF treatment cycle begins, women usually need to receive ovulation induction treatment. Ovulation promoting drugs are administered orally or by injection to simulate hormone changes during the natural cycle and stimulate the development of multiple follicles in the ovaries. Common promotion of emission

Egg drugs include clomiphene citrate and letrozole, etc. These drugs can simulate the action of estrogen in the body or inhibit the activity of aromatase, thereby stimulating follicular development. Ovulation promotion treatment is suitable for anovulation, polycystic ovary syndrome, etc.

Causes insufficient number of eggs.

After ovulation induction, when1-2 follicles in the ovary have a diameter of ≥18mm and 2-3 follicles in the ovary have a diameter of ≥17mm, theIVFwill perform egg retrieval. After the sperm and eggs are obtained, the IVFwill use the second-generation IVF

Infant technologyICSI(Intracytoplasmic Single Sperm Injection) uses a high-power micromanipulation system to inject a single sperm into an egg, allowing the sperm and egg to complete the combination to form a fertilized egg. The fertilized egg is then placed in a blastocyst culture vessel that simulates the maternal womb environment

n

Cultured in an incubator, it will develop into a blastocyst composed of more than 100 cells after five days. The blastocysts were then genetically tested through the third generation IVF technologyPGT-Mto screenfor abnormalities in the structure and number of chromosomes

Or diagnose whether it carries genetic disease-causing genes, so as to select high-quality and healthy embryos for transplantation, achieve eugenics and postnatal care, and achieve successful dreams.
