Operation steps of test tube baby
In vitro fertilization (IVF) is an assisted reproductive method. The following details the operation steps of IVF:
1. Ovulation induction and egg collection:
First, women need to be treated with ovulation promoting drugs to develop their ovaries and produce multiple follicles. Doctors will conduct regular ultrasound examinations to monitor the size and number of follicles. Once the follicle is mature, an egg collection operation will be performed. This operation is usually performed under local anesthesia, and doctors will use a slender needle to puncture the ovary and suck out the eggs.
2. Sperm treatment and in vitro fertilization:
After the eggs are collected, the doctor will put the paired sperm and eggs into the culture dish for in vitro fertilization. This process can be traditional IVF, that is, sperm is directly added to the culture dish; It can also be fertilized by microinjection sperm injection (ICSI), that is, single sperm is injected into the egg. The doctor will observe the fertilization and confirm whether there is a fertilized embryo after 24 to 72 hours.
3. Embryo culture and selection:
The fertilized embryo will be transferred to the culture dish for culture. Doctors will select the most promising embryo to be successfully embedded into the uterus according to the development and quality of the embryo. Usually, doctors will choose the best one or two embryos for transplantation or cryopreservation.
4. Embryo transfer:
Embryo transfer is usually carried out in a woman's uterus by inserting a slender catheter through the vagina. This process usually does not require the use of anesthesia, but sometimes it is also carried out under local anesthesia. Doctors carefully insert the embryo into the uterus to help it insert into the uterine wall. After transplantation, women need to rest for a period of time, waiting for pregnancy results.
How long does IVF surgery take?
The time of IVF surgery varies according to the specific situation. The following is the time range of general surgery:
1. Ovulation induction and egg collection:
Ovulation promoting drug therapy generally takes 10-12 days. The egg collection operation usually lasts about 20-30 minutes, but the preparation and recovery time before and after the operation may be longer.
2. Sperm treatment and in vitro fertilization:
The time of sperm treatment and in vitro fertilization varies according to the actual situation. If the traditional IVF method is used, the time to put eggs and sperm together is usually 12-24 hours. If ICSI technology is used, it may take longer to inject a single sperm into the egg.
3. Embryo culture and selection:
The culture time of embryos is usually 3 to 5 days. Doctors will regularly check the development and quality of embryos, and select the most suitable embryos for transplantation or cryopreservation during this period.
4. Embryo transfer:
The embryo transfer itself usually takes only a few minutes, but the preparation and rest time before and after the operation may take longer.
It should be noted that the above time is for reference only, and the specific situation should be determined according to the doctor's suggestions and personal physical conditions.
Summary
IVF is a kind of assisted reproductive technology. Through in vitro fertilization and embryo transfer, IVF can help couples who cannot conceive naturally realize their reproductive dreams. The operation steps include ovulation induction and egg collection, sperm treatment and in vitro fertilization, embryo culture and selection, embryo transfer, etc. The duration of the operation varies from person to person. Generally speaking, ovulation induction and egg collection take 10-12 days. Embryo culture and selection usually last 3-5 days, while embryo transfer itself only takes a few minutes. Considering the preparation and rest time before and after the operation, the whole process may take several weeks. For those couples who want to try IVF surgery, it is recommended to consult and plan in detail with a professional doctor.
