It is not always possible to obtain a successful result in treatment trials in IVF treatment. But a young couple usually needs to get pregnant after two or three attempts. In the group of couples over the age of forty, the number of in vitro fertilization attempts may increase, as failure rates normally increase.
The most important factor in the success rate of IVF treatment is the age of the woman. In IVF treatment trials, if the woman's age is younger than 35, even if everything goes perfectly, the success rate in each trial is around 60%. In the 35 - 37 age group, this rate decreases to 45%. In the 38-40 age group, the rate is 30%. In the 40 - 42 age group, the rate of getting pregnant decreases to 20%. For the age group of 42 and above, this rate decreases to lower figures. In women aged 45 and over, this rate decreases to 5%. Apart from the age of the woman, it is also effective whether the sperm of the man is normal, whether the ovulation functions are normal in the woman, and whether there is any problem in the uterus.
How many trials a family will make depends on the financial and moral strength of that family. However, a young couple is expected to get pregnant after two or three attempts. If you have the financial means, do not despair in any way. Even if you are old, do not despair. Believe what happens with a momentary miracle. Nothing is impossible. Don't let these rates upset you, what are we witnessing around us? I have seen even couples who have no children despite all their efforts for years and years, and even have children after cancer treatment.
