a)Age: Age is the most important factor which can affect your success of the IVF treatment. For e.g. if you are over the age of 35 years in such conditions you will not be able to produce the good quality of eggs for fertilization in spite of having the good quality of sperms, however, if your age is below 35 years than you not only produce good quality of eggs but also your chances of conception increases. So to plan your family your age should be ideal.
b)Body Weight: Your body weight is another major factor which can affect your success of IVF treatment which means if you are overweight then you have a major risk of miscarriages and also you have fewer chances of successful pregnancy. So while planning for your IVF treatment your body weight should be ideal neither it is overweight nor underweight because in both the conditions your IVF cycle will be affected and your success rate of conception also decreases.
c)Changes in Lifestyle: Your changes in your lifestyle will also impact the success of your IVF treatment. For e.g. if you or your partner or both of you are a chain smoker or consume alcohol regularly will decrease your chances of successful pregnancy. So if you are planning for the IVF treatment than at least 3 months before your treatment you should quit smoking or other drugs to achieve the successful outcome of the treatment.
