Do you believe your lover and you have chemistry? Well, it appears there definitely is some science behind it. I turns out that you can evaluate a future mates compatibility by comparing their DNA with yours? Mad science? Maybe, but it works.

Chemistry is what helps you make a good choice in a mate. However, it is a choice strictly geared toward reproduction, childbearing, not necessarily on how well your personalities and values mesh. What DNA will help you find is a mate who will turn you on and help you spawn children with strong genes and strong immune systems.

Some dating services are offering to help you find your perfect match this way based on your DNA compatibility.

Apparently, there really is something behind the assertion that our pheromones attract others.
By comparing gene pairs, scientists can determine whether your sex life will be good and whether you will be a good "childbearing" mix.

But nature has allowed us to determine this on our own -- without submitting swabs of our DNA. It is our olfactory sense. Do you ever wonder why you meet someone and instantly feel sparks? Your body is telling you that this person is a good match for you to recreate, reproduce, spawn offspring.

Some of the testing behind this DNA matching was done by having women smell men's dirty tshirts. I think they called it the Sweaty TShirt Experiment or something. It turns out that the tshirts the women found most appealing (I guess that smelled the best to them) belonged to men who were compatible with them based on DNA testing.

Who knew?

And the best match based on DNA, is the one who has several differences in his or her genes than the potential mate. It seems that the ones with the most similar genes we are not normally attracted to because they are so similar as to be possible family members.

I guess this was nature's way of preventing birth defects, etc. from incestuous relationships.

When you are a good match genetically, you reduce the chances of miscarriages, birth defects and increase the chance of your offspring having a strong immune system.

Some people are trying to capitalize on this by creating dating services that will match you with someone based on your DNA compatibility. Of course, privacy concerns need to be addressed, but the idea sounds fascinating, especially when your first level of choosing someone is based on a picture online or a written profile where you don't have an opportunity to let that "chemistry" and "pheromones" help your decision-making process.

But what if you don't even want children? Well, it still helps you find a mate with whom you will share a strong sexual attraction, which is important in any relationship.

However, it seems the true value of this science may be for those visiting a sperm bank in an attempt to have children. They will be able to find someone whose DNA will help them birth a child with strong genes and strong immune systems.
