Preparation of IVF
IVF technology is a kind of assisted reproductive technology, which helps couples who cannot conceive naturally to achieve their reproductive aspirations through in vitro fertilization and embryo transfer. There are several key steps to successfully conduct IVF. The first is the preparatory work.
1. Select the appropriate hospital:
Choosing a regular and experienced professional hospital is an important prerequisite for IVF. Select an institution with relevant qualifications and technical strength, such as Beijing Maternal and Child Health Hospital Assisted Reproduction Center, Shanghai Jiaotong University Ruijin Hospital Reproductive Medicine Center, etc.
2. Physician evaluation:
After selection in the hospital, the couple should have a detailed physical examination, including women's ovarian function, uterine conditions, and men's semen quality. The doctor will evaluate the appropriate IVF protocol based on the examination results and inform the precautions before and after treatment.
3. Mental preparation:
The IVF process may experience multiple failures and psychological pressure. Couples need to face it positively, be prepared, support each other in difficulties, maintain a positive attitude, and increase the probability of success.
In vitro fertilization and embryo culture
In vitro fertilization and embryo culture are the core links of IVF, which will be introduced in detail below.
1. Ovulation promotion:
Ovulation promotion refers to the use of ovulation stimulating hormone to promote ovarian ovulation. Doctors will adopt different ovulation promotion programs according to women's ovarian function to ensure proper release of hormones.
2. Egg retrieval:
After ovarian ovulation, mature eggs are taken out through endoscope assisted or pelvic surgery. General anesthesia or local anesthesia is required during egg retrieval to ensure the smooth progress of egg retrieval.
3. Sperm collection and processing:
Collect male semen samples, and then conduct in vitro fertilization of high-quality sperm and eggs, usually using conventional IVF or ICSI technology (injecting single sperm into eggs).
4. Embryo culture:
The fertilized eggs will be cultured in the incubator, which provides suitable temperature, humidity and nutrition conditions, so that the embryo can develop into a transplantable stage.
Embryo selection and transfer
Embryo selection and transfer is a key link in the process of IVF.
1. Embryo evaluation:
The doctor will evaluate the cultured embryos, including embryo quality, cell division, etc., and select the most suitable embryos for transplantation. Some hospitals also provide PGS/PGD (embryo chromosome screening) services to help screen normal embryos.
2. Embryo transfer:
Doctors will transfer embryos according to the quality of the embryo and the environment of the woman's uterus. Transplantation is usually carried out via a catheter through the cervix, which is simple and painless. If frozen embryos are needed, they can also be transferred at an appropriate time.
3. Luteal support:
After transplantation, doctors will give luteal support according to the situation to help mothers maintain excellent luteal function and increase the stability of pregnancy.
Pregnancy and pregnancy management
Once the transfer is successful, couples need to conduct pregnancy and pregnancy management to ensure the smooth development of the embryo.
1. Pregnancy confirmation and fetal protection:
About two weeks after transplantation, pregnancy test can be carried out to confirm whether pregnancy occurs. Once the pregnancy is successful, the doctor will take corresponding measures to protect the fetus, such as using progesterone and other drugs.
2. Regular birth inspection:
Conduct regular prenatal examination, including blood routine examination and ultrasound examination during pregnancy. The doctor will make a corresponding prenatal examination plan according to the situation of women, and supplement the dose of progesterone and other drugs as needed.
3. Health care during pregnancy:
During pregnancy, we should do a good job in postpartum health management, pay attention to diet and nutrition, avoid fatigue and mental stress, and reasonably arrange daily life to ensure the healthy development of embryos.
Summary
IVF is a complex assisted reproductive technology, which needs to go through several key steps, such as preliminary preparation, in vitro fertilization and embryo culture, embryo selection and transfer, and pregnancy and pregnancy management. Choosing a regular hospital, active pregnancy preparation and mental preparation are the basis for successful IVF. Obtain high-quality embryos through professional doctor evaluation, ovulation promotion, oocyte retrieval, in vitro fertilization and embryo culture. Embryo transfer and pregnancy management are the key to success to ensure the healthy development of embryos and the stability of pregnancy. Through reasonable solutions and meticulous care, IVF technology has brought good news to couples who cannot conceive naturally.
