Before getting married i want to go for infertility and reproductive organ tests, will it affect my system when presently there is no problem? help!

Not needed: There is generally no reason to do infertility testing before you start trying. They are designed to figure out why a couple with infertility cannot conceive, not to determine whether a couple will experience infertility. There are couples out there with abnormal tests who have no fertility issues and couples with normal testing who cannot conceive.
