Patient discussion about age

Q. I would like to know the best age for pregnancy? Hi I am Deontae; I got married before 1 year. I and my wife planned to have a baby after 3 years. But now she is 25. I would like to know the best age for pregnancy? Which will help us to change our plan?

A. actually there is no best age for pregnancy (as far as i know), but some studies and research had shown that after 35 years old, a pregnancy is categorized as high risk, because there are some abnormalities and labor complication that are tend to happened (statistically) along with the increase of mother's age (such as: down syndrome, genetic disorder, post-partum bleeding, miscarriage, etc.)

so if your wife is now 25, i think you guys still have another 5-10 years to "accomplish" your family plan, hehehe...
Good luck, and stay healthy always..
