Timing and preparation of IVF seeding
IVF technology is an important breakthrough in modern medicine, which has helped many couples who cannot conceive naturally realize their dreams of fertility. The seeding time and preparation of IVF is based on science and medical technology, and requires a certain amount of time and effort.
1. Routine health examination and assessment
Before deciding to carry out IVF, couples usually need to carry out a series of health examinations and assessments. These examinations can confirm whether the couple has any health problems that may affect pregnancy and pregnancy, such as whether the woman's ovarian function is normal, and whether the man's sperm quantity and quality meet the requirements. In addition, the condition of the woman's uterus and fallopian tube needs to be evaluated to ensure that IVF technology can be safely accepted.
The doctor may require the couple to have a comprehensive physical examination, blood test and sex hormone level test to understand the basic condition of the couple. In addition, the woman may also need to carry out special examinations such as ultrasonic examination, hysteroscopy and salpingography to ensure the normal function of the uterus and fallopian tubes.
2. Ovulation promoting drug treatment
Once the health assessment has been carried out and it is confirmed that the couple is suitable for IVF surgery, the next step is ovulation promoting drug treatment for women. This is to inject ovulation promoting drugs into the woman's ovary to stimulate the ovary to produce multiple mature eggs. The use of these drugs can increase the number of eggs and improve the success rate of pregnancy.
The specific use mode and dosage of ovulation promoting drugs are determined according to the specific conditions of the couple and the doctor's recommendations. Drug treatment usually needs to be carried out under the guidance of professional hospitals to ensure the correct use of drugs and monitor the development of follicles.
3. Egg collection and sperm collection
After treatment with ovulation promoting drugs, women's ovaries will produce multiple mature eggs. Next, we need to collect eggs and sperm.
Egg collection is usually carried out after the monitoring confirms that the follicle has reached the mature state. This process usually needs to be carried out under general anesthesia, and the doctor will collect the eggs through vaginal puncture. The collected eggs will be placed in a culture dish, waiting to combine with sperm.
At the same time, it is necessary to collect sperm samples from the man. The man usually needs to provide sperm samples through manual ejaculation after a period of abstinence. This sample will be processed in the laboratory to screen the best quality sperm.
4. In vitro fertilization and transplantation of test tube babies
After the collection of eggs and sperm, IVF and transplantation of IVF are required. This is to place sperm and eggs in a culture dish for in vitro fertilization, so that the fertilized eggs can be formed. Normally, doctors will choose the healthiest fertilized egg for transplantation.
The transplantation process is usually carried out by means of drug assistance. The doctor will place a thin tube in the woman's uterus and implant the fertilized egg into the uterus. This process is usually painless and needs to be carried out in professional medical institutions.
summary
The seeding time and preparation of IVF need to be carried out from health assessment, ovulation promoting drug treatment, egg and sperm collection, and in vitro fertilization and transplantation. These works are based on science and medical technology and need to be carried out under the guidance of professional hospitals.
In general, the whole process of IVF may take several months, depending on the individual conditions of the couple and the doctor's advice. Although there may be some inconvenience and discomfort in the process, IVF technology has brought new reproductive options for couples who cannot conceive naturally.
