Which of the following assisted reproductive technology has been used for the longest time period?

Artificial insemination is the assisted reproductive technology that has been used for the longest time period. It can help treat certain kinds of infertility in both men and women. In this procedure, sperms are inserted directly into a woman's cervix, fallopian tubes, or uterus. This makes the trip shorter for the sperm and bypasses any possible obstructions. Intra uterine insemination (IUI), in which the sperm is placed in the uterus, is the most common form of artificial insemination.
