Introduction
Under normal circumstances, tests required before embryo transfer include endocrine examination, endometrial examination, genetic testing, screening for infectious diseases, and immune function tests. Maintaining a healthy lifestyle, including a balanced diet, moderate exercise, sufficient sleep, and avoiding harmful substances such as tobacco and alcohol, can help maintain overall health and fertility.

Generally, tests required before embryo transfer include endocrine examination, endometrial assessment, genetic testing, screening for infectious diseases, and immune function evaluation. A detailed analysis is as follows:

1. Endocrine Examination

The endocrine system plays a crucial role in female fertility, particularly ovarian function, luteal function, and thyroid function. Endocrine testing can assess hormone levels such as follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, progesterone, and thyroid hormones, to determine whether the woman is suitable for embryo transfer.

2. Endometrial Assessment

The endometrium is a critical site for embryo implantation, and its thickness, morphology, and blood flow directly affect the success rate of embryo implantation. Endometrial evaluation, such as ultrasound or hysteroscopy, can assess the condition of the endometrium to ensure it is in optimal condition prior to embryo transfer.

3. Genetic Testing

Genetic testing aims to exclude chromosomal abnormalities or hereditary diseases to ensure embryo health. It includes karyotype analysis of both partners and genetic screening or diagnosis of the embryos.

4. Screening for Infectious Diseases

Infectious diseases such as hepatitis B, hepatitis C, syphilis, and HIV/AIDS may not only affect embryonic development but also be transmitted to the fetus through mother-to-child transmission. Therefore, screening for infectious diseases before embryo transfer is an important step in ensuring maternal and fetal health.

5. Immune Function Evaluation

Abnormal immune function may cause the mother's body to reject the embryo, thus affecting implantation and development. Immune function testing can assess the mother's immune status, and immunomodulatory treatment may be given if necessary.

Maintaining a healthy lifestyle including balanced nutrition, moderate exercise, sufficient sleep, and avoiding harmful substances such as tobacco and alcohol can help maintain overall health and fertility.

Is it suitable for patients with hydrosalpinx to undergo in vitro fertilization (IVF)?
In general, in vitro fertilization (IVF) refers to in vitro fertilization combined with embryo transfer (IVF-ET). Whether a patient with hydrosalpinx is suitable for IVF-ET depends on the specific circumstances. If the hydrosalpinx is mild, IVF-ET is usually feasible; however, if the hydrosalpinx is severe, IVF-ET may not be appropriate. Patients should communicate fully with their doctors, understand their own conditions, and follow medical advice.

Which health conditions are not suitable for in vitro fertilization (IVF)?
In general, in vitro fertilization (IVF) refers to the process of fertilization outside the body followed by embryo transfer. Individuals with severe reproductive system abnormalities, uncontrolled severe systemic diseases, acute infectious diseases, severe mental illnesses, malignant tumors, or other significant health issues are typically not suitable candidates for IVF-embryo transfer. It is recommended to consult a qualified physician or reproductive specialist before considering IVF-embryo transfer.

What are the early pregnancy symptoms after a successful embryo transfer?
Under normal circumstances, after a successful embryo transfer, women may experience early pregnancy symptoms such as missed period, breast changes, nausea and vomiting, fatigue, drowsiness, and mild abdominal pain. If any unusual symptoms or concerns arise after the transfer, it is recommended to promptly seek medical advice. The doctor will make a diagnosis and provide recommendations based on the specific situation.

Is a high-protein diet important after test tube embryo transfer?
Proteins play a crucial role as key components of human cells and tissues, particularly for women following in vitro fertilization (IVF) embryo transfer. Increasing protein intake appropriately not only enhances immune function, reducing the risks of early miscarriage and biochemical pregnancy, but also improves embryonic development potential and has a positive impact on embryo implantation.

Is it normal to experience abdominal pain after IVF embryo transfer?
Whether abdominal pain after IVF embryo transfer is normal depends on the severity of the pain. Mild abdominal pain that does not affect quality of life or work may be normal, often related to surgical stimulation, and symptoms can gradually improve with appropriate rest. Severe abdominal pain that impacts quality of life and is accompanied by other symptoms may be abnormal, often associated with factors such as infection or implantation failure.

Does in vitro fertilization (IVF) affect the health of the fetus?
In vitro fertilization-embryo transfer (IVF-ET) is an assisted reproductive technology that helps couples who are unable to conceive naturally to achieve pregnancy through in vitro fertilization. During the IVF-ET process, doctors strictly screen both sperm and eggs to ensure the quality of the fertilized egg. Additionally, a series of genetic screenings are performed before embryo transfer to reduce the risk of genetic diseases.

What should I pay attention to when eating pomegranate after test tube transfer?
In general, test tube transplantation refers to in vitro fertilization-embryo transfer (IVF-ET). After IVF-ET, precautions regarding pomegranate consumption include: allergic reactions, individuals with poor gastrointestinal health should avoid consumption, control portion sizes, time intervals between eating and medication, and ensure proper food pairing and nutritional balance. It is recommended that women avoid strenuous activities and maintain a positive emotional state after in vitro fertilization-embryo transfer.

What is the peak time for ascites after fresh embryo transfer?
The peak period for ascites after fresh embryo transfer occurs 3-7 days post-transplantation. In daily life, it is recommended to follow a diet principle of high protein, high vitamins, and easy digestion, with increased consumption of foods rich in high-quality protein such as eggs, milk, and fish, to improve plasma colloid osmotic pressure and reduce fluid leakage. At the same time, it is important to maintain adequate fluid intake while avoiding excessive water consumption, which may worsen ascites symptoms.
