Now a days test tube baby technique is generally used to solve infertility problem.
IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy, in which a fertilized egg is implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate.
Asisted Reproductive Technology (ART)
ART involves the use of one or several techniques to bring the sperm and egg together, eliminating the chance element to conception and reducing or removing the need for the sperm to swim through the cervix and the fallopian tubes to meet the egg. ART techniques have revolutionised the management of infertility. In most instances, ART involves recovering the eggs from the ovaries and fertilising them with the sperm outside the body in the laboratory. The developing embryos are then replaced by artificially into the uterus.
