Development of IVF
IVF refers to in vitro fertilization (IVF) and embryo transfer technology, so that infertile or infertile couples have the opportunity to have children. The development of IVF technology has gone through many years of exploration and practice, and constantly improved and innovated, which has brought good news to couples who cannot conceive naturally. The following will detail the development of IVF from four aspects: pregnancy preparation, egg taking and fertilization, embryo transfer, and birth and growth.
Pregnancy preparation
Preparation for IVF pregnancy usually involves physical examination, disease screening and treatment. Both couples need to undergo physical examination, including gynecological examination, semen analysis and chromosome examination, to evaluate and determine whether IVF technology is suitable. If one of the couples has reproductive system diseases, such as polycystic ovary syndrome, oviduct obstruction, etc., they also need to receive corresponding treatment to increase the chance of successful pregnancy.
Next, the woman needs to receive ovulation induction treatment to promote the growth and development of follicles through hormone injection. Doctors will monitor the development of follicles and give ovulation guidance drugs at the appropriate time. This makes it possible to collect mature eggs in the process of egg retrieval, and prepare for the subsequent fertilization process.
At the same time, the couple needs to sign relevant informed consent forms and conduct psychological counseling to understand the whole process of IVF and the risks and difficulties that may be faced.
Egg taking and fertilization
Fetching eggs is one of the key steps in IVF technology. Before the egg retrieval operation, the woman needs to be anesthetized. The doctor uses ultrasound guided fine needle puncture to remove the eggs from the ovary. This process is usually carried out in a clinic or hospital, without hospitalization, and can be discharged after taking eggs for a few hours.
The removed eggs will be placed in a culture dish and fertilized in vitro with sperm donated from the man. Sperm can be obtained by natural ejaculation or by sperm donor. After in vitro fertilization, the embryo will further develop in the culture dish, which usually takes 2-6 days. After necessary screening, the best embryo will be selected for embryo transfer.
The egg taking and fertilization process is carried out in the IVF professional hospital or reproductive center, and professional doctors and technicians will monitor the whole process to ensure the safety and accuracy of the whole process.
Embryo transfer
Embryo transfer is one of the key links of IVF, that is, to transfer the cultured embryos into the woman's uterus. Embryo transfer usually takes place after the mother's endometrium is fully prepared. The doctor will use a soft tube to send the embryo into the uterus through the vagina. This process is usually simple and painless without anesthesia.
After embryo transfer, the woman needs to lie still for a period of time, and sometimes she needs to take some drugs to promote embryo implantation. Next, couples need to wait a few days to two weeks for a pregnancy test to confirm whether the pregnancy is successful.
Birth and growth
If the embryo is successfully implanted, it means that the IVF is successfully conceived. From then on, the child will develop healthily in the mother's womb until delivery. Mothers need to receive regular prenatal examination and guidance throughout pregnancy to ensure the health of their children.
After the birth of children, they will grow up like other children and be loved and cared by their parents. The development process of IVF is no different from that of natural pregnancy. They will grow, learn and explore the world together with their families.
The continuous development and improvement of IVF technology has provided many infertile or infertile couples with opportunities to realize their reproductive dreams. Through the steps of pregnancy preparation, egg taking and fertilization, embryo transfer, birth and growth, couples can welcome their own babies. The promotion and application of IVF technology not only brought joy to families, but also opened a new chapter in medical science and technology.
Summary
The development of IVF includes pregnancy preparation, egg retrieval and fertilization, embryo transfer, birth and growth, etc. Through physical examination and disease treatment of both couples, ovulation induction treatment of the woman, and in vitro fertilization and transfer of embryos, IVF technology has brought new fertility hope to couples who cannot conceive naturally. In the end, these babies will grow up healthily under the care of their families and enjoy life as much as other children.
