Any medical technique that attempts to obtain a pregnancy by means other than by intercourse is defined as ART. These techniques involve the manipulation of sperm or Oocyte or both, and the gametes or the embryos are transferred into the uterus or fallopian tubes. ART includes Intrauterine Insemination (IUI), In Vitro Fertilisation-Embryo Transfer (IVF-ET), Intra Cytoplasmic Sperm Injection (ICSI), Assisted Hatching (AH) etc
If the treatment procedure is successful, one or more embryos will implant in the uterus and the pregnancy will result, just as it happens in the natural process of conception
