art in which eggs are removed from the ovary of the female fertilised and then placed in her fallopian tube

Solution:

Assisted reproductive technology(ART) is the technology used to achieve pregnancy in procedures such as fertility medication, in vitro fertilization, surrogacy etc. 
  • In vitro fertilisation (IVF– fertilisation outside the body in almost similar conditions as that in the body) followed by embryo transfer (ET) is one of such methods.
  • 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.
  • Embryos formed by in-vivo fertilisation (fusion of gametes within the female) also could be used for such transfer to assist those females who cannot conceive.
Hence, the answer is IVF.
