Dear Student,
ZIFT − It stands for zygote intra fallopian transfer. In ZIFT, the sperm from a donor male and the ova from a donor female are fused in the laboratory. The zygote so formed is transferred into the fallopian tube at the 8 blastomeres stage.
GIFT − It stands for gamete intra fallopian transfer. In GIFT, females who cannot produce ovum, but can provide suitable conditions for the fertilisation of ovum, are provided with ovum from a donor.
Artificial insemination is the process of injecting the semen artificially (by any way other than sexual intercourse) into the female reproductive tract (vagina or oviduct) resulting in the formation of new organism. In this process semen from a healthy male is injected into the female reproductive tract of the female to produce a new organism possessing the wanted characteristics from both its parents.
