(a) GIFT is an assisited reproduction technology which helps in the tensfer of an ovum collecfted from a donor into the fallopian tuve of another female who cannot prooduce ova but can provide suitable environment for fertilization and further development of embryo in the oviducts. (b) CU-T and CU-7 are the intrauterine contraceptive devices used as means of birth control. When introduced into the female reproductive tract, teh coper ions start releasing. These ions reduce sperm motility and their ferrilizing capacity. The hormones released make the uterus unsuitable for immplanation and the cervix hostile to the sperms.
