The Hisory
                   Major Advances Towards The End Of The Last Century Laid The Foundations For The Modern Reproductive Technologies, And Exactly 100 Years After The First Recorded Experiments To Fertilise Animal Eggs In A Laboratory The First Test Rube Baby Was Born. This Event Drew Together Three Major Strands Of Scientific Investigation. First There Was The Research Into The Development Of The Human Life After The Egg Is Fertilized. A Pair Of American Scientists Claimed To Have Created A Human Embryo In A Laboratory As First Substantial Report Of The Production Of A Human Embryo In Vitro, Which Literally Menas In Glass, Came In 1971. A Second Strand Was The Development Of Medical Technology , In Particular That Of The Laparoscope, Which Made It Possible To See And More Fully Understand The Woman’s Reproductive System. The Pioneering Work On This Was Done At The Turn Of The Century. Third Was The Understanding Of The Hormones Which Regulate Human Reproduction. This Evolved Rapidly Between The 1920s And 1950s And With It Came The Development Of Drugs Which  Could Artificially Control The System, Either Repressing Or Stimulating The Woman’s Monthly Cycle. Amongst The Well Known Drugs Which Emerged As A Result Of This Research Were The Contraceptive Pill, And Also Widely Used Fertility Drugs That Encourage Women To Ovulate.
               By The 1960s And 1970s Work Was Being Carried Out Virtually In Parallel In The Face Of Some Stringent Public Opposition, In America, Australia And Britain To Try To Perfect A Process For Fertilizing A Human Egg In A Laboratory And Transferring The Tiny Embryo Back To The Woman To Produce A Baby. The Australians Achieved Two Pregnanied In 1973, But Neither Or Them Survived. It Was The British Team, Patrick Steptoe And Robert Edwards, Who Achieved The First Live Birth In July 1978 As A Result Of In Vitro Fertilization And Embryo Transfer, Now Known Around The World As Ivf.
               World-Wide Developments Followed Very Quickly. In Australia In 1980 Came The First Ivf Birth After Stimulation Of The Woman’s Ovaries By Fertility Drugs, A Process Which Has Now Become Quite Standard In Iva Treatment. Four Years Later The Same Team Achieved The First Test-Tube Baby Born Using A Donated Egg And Pioneered The Freezing Of Human Embryos. Since Then Ivf And Similar Treatments Have Proliferated Around The World And Today In Many Countries There Are Clinics To Help Infertile Couples Have Children.
