1、 Pre inspection and evaluation
IVF is a kind of assisted reproductive technology, which requires a series of examinations and evaluations on both spouses to ensure that appropriate programs can be selected.
First of all, it is necessary to understand the birth history and medical history of both husband and wife, including whether they have ever been pregnant, whether they have ever had abortion, and whether they have other diseases. Then a comprehensive examination of the reproductive system was carried out, including male semen analysis, female ovarian function and uterine condition assessment.
In addition, both husband and wife also need to carry out genetic assessment and psychological assessment. Genetic evaluation is mainly to exclude the possibility of hereditary diseases, and to know whether there are diseases that can be passed on to the next generation through the genetic examination of both spouses. The purpose of psychological evaluation is to evaluate whether the test tube baby technology is suitable for both husband and wife, because the technology will have a certain impact on the psychology and quality of life of both husband and wife.
2、 Ovulation induction therapy
Ovulation induction therapy is one of the key steps of IVF technology. Drugs can promote ovarian ovulation and increase the chance of fertilization.
Before ovulation induction treatment, women need to have a basic follicle count to determine the number and quality of eggs. Then, according to the specific situation, select appropriate ovulation promoting drugs for treatment. In the process of ovulation induction, it is necessary to periodically detect the development of follicles, and determine the optimal ovulation time through ultrasonic examination.
During ovulation induction treatment, it is also necessary to monitor the hormone level in women's blood to judge the progress of treatment and adjust the drug dose. Once the follicle develops to the proper size, the doctor will choose the appropriate time to collect eggs.
3、 In vitro fertilization and embryo transfer
In vitro fertilization and embryo transfer are the core steps of IVF technology. Pregnancy is achieved by fertilizing eggs and sperm in the laboratory, and then transferring embryos into the female uterus.
In vitro fertilization is generally divided into conventional in vitro fertilization and PGT-A (embryo chromosome screening) in vitro fertilization technology from embryo culture to blastocyst stage. In vitro fertilization (IVF), eggs and sperm are placed in a culture dish for fertilization. PGT-A technology is to screen the chromosome of embryos after in vitro fertilization, screen the embryos with abnormal chromosome, and select healthy embryos for transfer.
The selection of the number of embryos to be transferred and the time of transfer shall be determined according to the specific conditions of the couple and the doctor's suggestions. After transplantation, blood test or ultrasound examination was used to determine whether the pregnancy was successful.
4、 Pregnancy monitoring and health care
Once pregnancy is successful, pregnancy monitoring and health care are needed to ensure the healthy development of embryos and the safety of mothers.
Pregnancy monitoring mainly includes blood testing, B-ultrasound examination and psychological counseling. By monitoring the progesterone and other related indicators in the blood, we can judge whether the pregnancy is normal. B-ultrasound can observe the development of the embryo, heartbeat and endometrial thickness, so as to find and deal with abnormalities in a timely manner. Psychological counseling is to help couples cope with psychological pressure and changes during pregnancy.
In addition, attention should also be paid to the adjustment of diet and living habits during pregnancy to avoid eating stimulating food and contacting harmful substances. Regular medical treatment and following the doctor's advice can improve the success rate of IVF and protect the health of mothers and infants.
Summary
In Henan Province, IVF technology has gradually been widely used. In order to ensure the success rate of IVF and the health of mothers and infants, it is necessary to carry out preliminary examination and evaluation, ovulation induction treatment, in vitro fertilization and embryo transfer, as well as pregnancy monitoring and health care. These are indispensable links in the process of IVF and need to be carried out in the real hospital.
Through scientific examination and treatment, IVF technology can help more couples who cannot conceive naturally realize their dreams of childbirth and bring them new hope and happiness.
