Which of the following methods of ART involve in-vivo fertilization?

In vivo fertilisation involves the fusion of the sperm and the ovum inside the body of the female. In in vitro fertilisation, the fusion occurs in a laboratory, outside the body of the female.
In artificial insemination, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina (intravaginal insemination) or into the uterus (IUI – intra-uterine insemination) and fertilisation occurs in vivo. GIFT involves the transfer of ovum in the fallopian tube. Fertilisation occurs in vivo.

In case of ZIFT (zygote intrafallopian transfer), ICSI (intracytoplasmic sperm injection), IUT (intrauterine transfer),  fertilization takes place outside the body in almost similar conditions as that in the body (IVF- in vitro fertilization)
