उत्तर
- IVF stands for In Vitro Fertilization.
- It is a modern medical technique that helps childless couples have their own biological child.
- IVF is used when couples face problems such as low sperm count, blocked oviducts (fallopian tubes), or other fertility issues.
- In this technique, an ovum (oocyte) is collected from the mother and fertilized with sperm collected from the father outside the body in a laboratory.
- Since fertilization takes place in a test tube or culture dish, IVF is commonly known as the test-tube baby technique.
- The embryo formed is then implanted into the uterus of the biological mother or a surrogate mother at the appropriate stage for further development.
