Assisted Reproductive Technology (ART), according to WHO, refers to infertility treatments where both eggs (oocytes) and sperm are handled ex-vivo to achieve pregnancy. In conventional ART procedures, the oocytes and sperms are combined in a laboratory ex vivo (i.e. outside the human body) and the resulting embryo (mature and fertilized oocyte) is implanted back into a woman.
ART’s includes techniques such as In-vitro fertilization (IVF), Intracytoplasmic Sperm Injection (ICSI), Gamete Intra-Fallopian Transfer (GIFT) or Zygote Intra-Fallopian Transfer (ZIFT) .
