What is in vitro fertilization
IVF is an assisted reproductive technology, also known as in vitro fertilization-embryo transfer (IVF-ET), which uses reproductive medicine technology to realize the entire process of artificial insemination, egg fertilization, embryo culture, embryo screening and embryo transfer. It is a baby conceived in a test tube and then implanted into the mother\’s uterus. With the assistance of operations and drugs, the baby is assisted to conceive on the basis of a controlled environment.
The specific process and time of IVF
1. Female ovulation induction
Before the IVF procedure can officially begin, a woman needs to encourage her ovaries to grow more eggs. The doctor will inject her with a drug called follicle-stimulating hormone (FSH) to stimulate the ovaries to grow multiple follicles.
2. Egg retrieval and sperm retrieval
About two weeks later, the doctor will use ultrasound to guide a very small needle to the ovary, remove the well-developed eggs from the female ovary, and put the removed eggs into a plate of culture medium to wait for the sperm to merge. Sperm is also collected, usually through voluntary donation or frozen sperm.
3. In vitro fertilization
The egg and sperm carry dissolving drugs to facilitate their encounter and stimulate fertilization of the egg. Take out 2 backup eggs and 150,000 sperm and put them into a laboratory dish for culture. The next day they were transplanted into 2 different petri dishes and photographed for comparison with the previous petri dish containing eggs and sperm. When a single sperm transplanted into a petri dish enters an egg and successfully combines, it waits quietly for several hours to confirm the successful combination, while the egg \”cell divisions\” begin to grow more embryos.
4.Embryo transfer
The duration of embryo culture is usually 3-5 days. The doctor will evaluate their health and select relatively healthy embryos for transplantation, usually 1-2 embryos after having comprehensive data and considering the patient\’s surgical criteria. The doctor inserts the embryo into the female uterus through the vagina. The process is similar to hysteroscopic implantation and is painless.
Risks of IVF surgery
The risks of IVF are the same as those of surgery. IVF is a complex and expensive procedure, and the possibility of surgical failure exists. Among them, overweight and women over 40 years old need to pay more attention. You may encounter many rebounds during the IVF process, such as possible damage to healthy eggs, possible embryo splitting, possible miscarriage after pregnancy, and other common situations.
In vitro fertilization application scenarios
IVF has now become one of the best solutions for infertility symptoms worldwide, and is suitable for patients with fallopian tube blockage, ovarian dysfunction, hypospermia and other symptoms. Under special circumstances, resistant drugs are not applicable. After the operation, the possibility of success is greatly improved while ensuring the normal development of the baby. Generally speaking, the success rate of infertile couples in obtaining their own \”noble babies\” through IVF surgery is very high. In addition, if it is difficult to prepare for pregnancy due to age, you can also use the assistance of in vitro fertilization technology.
Summary
In vitro fertilization is an assisted reproductive technology used in infertilityIt is widely used among women suffering from infertility. The specific process covers steps such as female ovulation induction, egg and sperm retrieval, in vitro fertilization and embryo transfer. The risks in the operation include operation failure and operation success rate. The IVF operation is based on the proof of many scientific practices and seeks to pioneer and develop. Under appropriate circumstances, for couples affected by age, disease and other factors, it can provide the opportunity for IVF with a relatively high chance of success.
