About Infertility Treatment

Infertility treatment is a treatment given to couples who wish to conceive and bear a child but have not shown signs of pregnancy for a certain period of time.
Today, one in 14 babies is born through IVF, 35.0% or approximately 1 in 2.9 couples have ever worried about infertility, and 18.2% or approximately 1 in 5.5 couples have actually undergone (or are currently undergoing) infertility testing or treatment, so infertility treatment is no longer such a rare medical practice.
It is known that the older both men and women get, the less likely they are to conceive, whether through fertility treatment or natural conception.
Couples who are hoping to have children but are having difficulty conceiving should try testing as soon as possible.

What is specific infertility treatment?

Of these treatments, IVF and ICSI in particular tend to be expensive because they require special techniques and equipment in addition to being free treatment (self-funded).
For this reason, many municipalities provide subsidies for these treatments as "specific Infertility treatments.
For more information, please refer to the website of your prefecture or municipality.

Infertility Treatment and Probability of Natural Conception

The pregnancy rate per embryo transfer is approximately 20-30%, which is about the same as the probability of natural conception in a healthy reproductive age male and female who have unprotected sexual intercourse.
There is still much that is not understood about the mechanism of pregnancy, and it is difficult to exceed the probability of natural conception in fertility treatment.

In both fertility treatment and natural conception, the older both men and women get, the less likely they are to conceive.
Couples who are hoping to have children but are having difficulty conceiving should definitely try testing as soon as possible.
