Infertility is defined as the state of being unable to produce offspring even after having sexual intercourse. Infertility can be resolved with 3 methods, they are-

This results in a zygote or a test-tube baby.

  • Zygote Intrafallopian Transfer (ZIFT)- Zygote intrafallopian transfer (ZIFT) is an ART procedure where fertilization occurs in a laboratory. The t formed zygote is then transmitted to the Fallopian tube of the mother using a technique called laparoscopy.  It is also called Tubal Embryo Transfer.

  • Gamete Intrafallopian Transfer (GIFT) - Gamete Intrafallopian Transfer is a procedure where the gametes (sperm and ova) are transferred directly into the fallopian tube. In this technique, fertilization and zygote formation is much more natural as it occurs within the Female body.
