When Considering Your Chances Of Success, You Need To Look Carefully At What Is Meant By It, And What Is Used As The Baseline For Measurement. There Are Many Different Stages Of Ivf Treatment And Each One Has Its Own Success Rate. The Success Rate Per Treatment Cycle Will Be Much Lower Than Per Embryo Transfer Because For So Many Couples The Early Stages Of Treatment Do Not Work. Up To A Quarter Who Start Treatment May Not Even Reach The Stage Where The Woman Has An Embryo Transferred Back Into Her Womb.
Frequently Success Rates Are Given In Terms Of Pregnancies. But This Cab Be Seriously Misleading, As Many Pregnancies Will Not Continue Through To The Birth Of A Child. Pregnancy Will Not Continue Through To The Woman May Have A Positive Test, But There May Be No Sign Of Pregnancy On An Ultrasound Scan And She Then Bleeds. In Addition, The High Level Of Monitoring Of Women During Ivf Treatment Will Pick Up A Pregnancy At A Very Early Stage. In Nature, Many Are Not Viable And Are Lost At Such An Early Stage That The Woman Might Not Ever Realize That She Was Pregnant. For These Reasons The More Cautious Clinics Will Only Chalk Up A Success Where A Foot Heartbeat Has Been Detected By Ultrasound Confirming A Clinical Pregnancy.
The Second Measure Of Success Is The Live Birth Reate, Often Called The Take Home Baby Rate. It’s Important To Look At This Because It Shows The Chances Of The Desired End Result Going Home From Hospital With Your Own Baby. The Live Birth Rate Is Lower Than The Pregnancy Rate. Unfortunately, Even Once The Diagnosis Is Assured, Ivf Has A High Level Of What Is Euphemistically Called Pregnancy Wastage What Most Women Would Call Miscarriage. Whether This Is Higher Than For Naturally Conceived Pregnancies Is A Matter Of Debate. Sometimes It Can Be Hard To Get An Accurate Live Birth Rate. Clinics May Not Know The Ultimate Outcome Of A Confirmed Pregnancy, While Others May Be Reluctant To Take Responsibility For Mistakes Made By Others During Antenatal Care Of Childbirth.
