How do IVF do it?

For infertile patients, if they can't have children through other treatments, they will be depressed, but at least IVF technology can help us realize our hope of having children. Many people know about IVF, but I'm afraid it's hard for others to know exactly how IVF is done except the patients who actually do IVF. Don't worry, in the following content, we will introduce how IVF is done, hoping to help you.

In fact, IVF is not far away from us. Many lovely babies around us were born with the help of IVF technology. For most people, IVF technology is still a very distant and mysterious concept. In fact, in today's era of rapid development of science and technology, IVF has become a very common medical means to help those patients with fertility disorders achieve the purpose of continuing their offspring. Many infertile patients have successfully achieved their fertility goals through IVF technology after many failed pregnancy preparation.

So, how does the "in vitro fertilization" technology that makes many people feel mysterious work? What will ordinary people who finally choose IVF because of fertility disorder face when receiving treatment?

First of all, let's talk about what IVF is.

"IVF" is a common name for in vitro fertilization-embryo transfer. Whether through natural conception or artificial insemination, it is generally necessary for eggs to combine with sperm in human fallopian tubes to form fertilized eggs, which are then transported to the uterine cavity for implantation, thus giving birth to new life.

For various reasons, it is necessary to take out the egg manually, meet the sperm naturally in vitro "test tube" (Petri dish) and fertilize it, or it is necessary to fertilize it by microinjection in vitro. Then continue to culture in the "test tube" for about 2 to 3 days to form multicellular embryos, and finally transplant them back to the uterine cavity of the mother for growth and development.

This process just transferred the work that should have been done in the fallopian tube to the embryo laboratory, so it was called "test tube baby".

Why did I become a test-tube baby?

"Do I need to be an IVF?" "Do I have any other choice in order to have children?" However, patients with fertility difficulties have asked similar questions more or less.

In fact, not all infertile patients need IVF treatment. The doctor will comprehensively analyze the patient's age, infertility years, ovarian reserve function, previous birth history, operation history, tubal lesion degree, semen condition, and whether there are other infertility reasons, and formulate the most suitable treatment plan for the patient. Of course, due consideration will be given to some economic factors.

What kind of test-tube baby?

It has been more than 40 years since IVF was born, and there have been one or two generations of IVF. Some patients may be worried about how to choose IVF for treatment. IVF is not an upgrade or update of the software version, and different choices should be made according to the specific situation of each couple.

The first generation of IVF: also known as in vitro fertilization-embryo transfer technology, this technology is called the first generation of IVF. It is suitable for almost all infertile patients, such as some tubal factors, endometriosis, or patients with unexplained infertility, polycystic ovary syndrome, male factors or other assisted reproductive technology failure.

The second generation of IVF: To be precise, the second generation of IVF is actually called intracytoplasmic sperm injection. It is a very "precise" technique, which needs to be observed under a microscope, using a micromanipulation system, and then manually injecting a sperm into an egg cell of a follicle to fertilize it. The source of sperm can be fresh sperm, of course, it can also be frozen-thawed sperm, and it can also be sperm taken out by epididymis and testis puncture.

The third generation of IVF: refers to the related gene detection before embryo implantation in uterus. This technology will provide couples with children at high risk of genetic diseases with the opportunity to have healthy children.

How to be a test-tube baby?

If the doctor advises you to treat IVF, and you have accepted the doctor's advice, then the treatment process of IVF will become the focus of our patient friends' greatest concern. The treatment of IVF is divided into six steps, and the treatment time of each cycle varies according to the patient's condition.

The first step: make some preliminary preparations for IVF, including laboratory tests, troubleshooting abnormal situations, reviewing documents and establishing medical records.

Step 2: Make a plan to promote ovulation.

Step 3: Take eggs through vagina under anesthesia, and the man takes sperm. Then in vitro fertilization and important embryo culture were carried out in the embryo laboratory.

Step 4: Select very high-quality embryos to complete the transfer. At the same time, it is necessary to freeze the remaining unused high-quality embryos.

Step 5: corpus luteum support. Due to the influence of ovulation induction drugs and surgical procedures, patients receiving IVF cannot produce enough progesterone to support the implantation and growth of embryos, so progesterone drugs are needed to protect the fetus.

Step 6: Two weeks after embryo transfer, the woman will take a blood test and detect HCG (chorionic gonadotropin) to find out if she is pregnant. If you are pregnant, continue to take the medicine according to the doctor's advice and check it on time. If you can't get pregnant, you can stop taking medicine and wait for menstruation. Then you should communicate with the doctor in time. After about 2 to 3 normal periods, the frozen embryos (if any) will be selectively transplanted or a new cycle will be started.
