Summary statement on factors affecting success rates

A successful outcome, ie a live term birth of healthy baby, after ART treatment is dependent on multiple factors affecting the quality of the sperm and eggs and which in turn affect the subsequent ability of the embryo to start a pregnancy and develop successfully to term.

The most significant of these are the age of both male and female, but in particular female age. Cause of infertility can have a profound negative effect on egg and sperm quality. Other harmful factors relate to lifestyle, such as being overweight as well as alcohol and caffeine consumption and smoking.

You should be aware that not every treatment cycle will result in successfully obtaining eggs or in the development of an embryo or blastocyst that is suitable for transfer or freezing. Not every cycle will result in a pregnancy.
