Types of (IVF) In Vitro Fertilization

What is In Vitro Fertilization (IVF)?

What is IVF and its Types? Modern reproductive technology used to treat infertility has provided many infertile couples with in vitro fertilization, where the conception process takes place outside the woman’s body in a test tube.

Usually, one or two embryos are relocated into the uterus of a woman and the future’s remaining use.  In Vitro Fertilization was originally used to treat women with obstructed or blocked fallopian tubes. Today this technique is used to manage or treat many serious infertility problems, including the male factor.

 The IVF cycle includes the following stages: stimulation of ovarian function, vaginal puncture of the ovaries to collect eggs, fertilization, embryo culture, and transfer of embryos to the uterine cavity. We will describe all these stages in more detail in the following subsections.

What are the IVF protocols (types of in vitro fertilization)?

Distinguish between stimulated IVF and natural IVF. The two main variants of the IVF stimulation protocol are the short protocol and the long protocol. Also, there are Japan’s IVF agreement, freezing agreement, and natural circulation agreement. So, in other words, there are different types of in vitro fertilization.

Types of in vitro fertilization

Long IVF protocol

This type of IVF is a preparation stage; in this stage, the expert prepares a woman to become pregnant and then transfers the embryo into the uterine cavity. The length agreement needs to go through the following training cycle:

  • Drug stimulation of the ovaries;
  • Follicular puncture;
  • Embryo Transfer;
  • Hormone replacement therapy can maintain the important functions of the embryo;
  • The final pregnancy test.

With this type of artificial insemination, the female body’s hormone background is completely under the control of the specialist. The maximum number of eggs obtained by ovarian stimulation is 20. This method is considered the most effective.

In this case, a long agreement will be assigned:

  • Overweight woman.
  • Uterine fibroids.
  • Endometriosis

There are a technique and its shortcomings. The main danger is the risk of ovarian hyperstimulation. Excessive stimulation can cause serious problems and complications. The advantages of the long protocol include the ability to control endometrial growth and follicular maturation completely.

Short IVF protocol

A brief experiment is carried out on the third day of the menstrual cycle, starting with ovarian stimulation. The difference between it and the long-type IVF is that there is no egg fertilization period. Therefore, the mature amount of the egg is much smaller, and the egg becomes weaker.

This method is mainly used for older women. The duration is four weeks, characterized by the absence of the risk of ovarian overstimulation, which is considered a major advantage. Women do not need to take many powerful hormone drugs, so serious complications are also ruled out. The disadvantage is that a small number of eggs mature; also, ovulation cannot be controlled by professionals; it can happen spontaneously.

Gentle IVF program in the natural cycle

When choosing this type of artificial insemination, avoid using hormone drugs to stimulate ovulation. Follicle maturation occurs naturally.
