Fertility treatments are not an easy experience for couples that can’t achieve pregnancy in a natural way, since they are tough processes on the body and they are long. Besides, these therapies always have emotional implications that may affect both members of the couple in a different way, since the result is not always what the couple expected.

Not giving up on a fertility treatment

The success rate achieved at the end of an infertility treatment will depend directly on the assisted reproductive technique used.

But this is not the only factor that plays a role, there are also some other important factors, such as the fertility problem, the time of sterility and one of the most crucial: the age of the woman. The specialist in fertility takes into account all these factors and the specificities of the case and decides the assisted reproductive technique that must be performed.

Success rate depending on the technique

The approximate success rates depending on the technique used will be shown:

  • Artificial insemination (AI): the pregnancy rate is up to 50% after several attempts, while it doesn’t exceed 20% at the first attempt.
  • In vitro fertilization (IVF): in this case the probabilities are higher, since after 3 – 4 attempts the chances increase to 90%.
  • Egg donation: in this case and using other more complex techniques, the highest pregnancy rate is achieved with 95% of chances after the fourth attempt.

Don’t give up

An important factor to take into account when a person decides to turn to assisted reproductive techniques is perseverance. It is a tough process, and the drop-out rates are high. 25% of women that go through their first IVF without success stop the treatment, and this number increases with the number of failures.
