What is Test Tube Baby Process?


The Test tube baby process is defined as the babies who are conceived with the help of IVF treatment process are known as Test Tube Babies.
The process of test tube baby includes the fertilization of an egg outside the body. It is a process of fusion of female gamete (egg) with the male gamete (sperm) in a laboratory dish. In the case of normal pregnancy, a male gamete enters a female gamete through the process of mating and fertilization takes place inside the body of the female after the release of matured eggs from the ovaries. This method is known as normal or unassisted conception.

However, in some cases, some women are unable to conceive through the natural conception process. In this case, after the failure of various less expensive techniques, some women may opt for test tube babies process.

The technique of test tube baby process or how the test tube baby process is carried out:




This is one of the most commonly used procedures. Eggs are combined with the partner's sperm in a glass dish in the laboratory. Once fertilization has occurred, the resulting embryos develop for 3 to 5 days before being placed in the uterus.

2. Intracytoplasmic Sperm Injection (ICSI):




One of the partner's sperm is placed inside the egg with the help of a microscopic needle, rather than many sperms positioned close to the outside of the egg as in IVF, in a dish in a lab. Once fertilization occurs, the resulting embryo is placed in the uterus.

3. Gamete Intrafallopian Transfer (GIFT):




Transfer of an ovum collected from a donor into the fallopian tube (GIFT) of another female who cannot produce one, but can provide the suitable environment for fertilization and further development.

4. Zygote Intrafallopian Transfer (ZIFT):


In the test tube baby process, ova from the female and sperm from the male are collected and are induced to form zygote under stimulated conditions in the laboratory. The zygote or early embryo (with up to 8 blastomeres) could then be transferred into the fallopian tube (ZIFT) and embryos with more than eight blastomeres into the uterus (IUT - Intra Uterine Transfer) to complete its further development.

5. Artificial Insemination (AI):


If the infertility of male is either due to the inability of the male partner to achieve an erection of penis to inseminate the female or due to very low sperm count in the semen, it is corrected by Artificial Insemination. In AI, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or the uterus (IUI - Intra Uterine Insemination) of the female.

6. Donor Egg or Embryo:

If one is unable to conceive using her eggs, an egg donated by another woman is mixed with partner's sperms and the resulting embryo is implanted in the uterus. This process can also be performed with a donated embryo or sperm.

7. Surrogacy or use of gestational carrier:

Another woman carries embryo or a donor embryo to term.
