Which among the following is not a ART(assisted reproductive technologies)?

IUDs

Among the options provided, "IUDs" (Intrauterine Devices) is not an Assisted Reproductive Technology (ART).

Assisted Reproductive Technologies (ART) are medical procedures used to treat infertility by manipulating eggs, sperm, or embryos outside the body. These technologies aim to help individuals or couples achieve pregnancy when natural conception is difficult. Some examples of ART include:

In this method, popularly known as test tube baby programme, ova from the wife/donor (female) and sperms from the husband/donor (male) are collected and are induced to form zygote under simulated conditions in the laboratory. The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT–zygote intra fallopian transfer) and embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development.

Transfer of an ovum collected from a donor into the fallopian tube (GIFT – gamete intra fallopian transfer) of another female who cannot produce one, but can provide suitable environment for fertilisation and
further development is another method attempted.

Therefore, among the options provided, IUDs are not classified as Assisted Reproductive Technologies (ART).
