For the purposes of safe sex and to avoid pregnancy always, always assume that you are fertile. To seriously answer this question....Unless you have had very serious childhood disease or if you have a genetic abnormality then assume you are fertile. I have seen men in their 40's who have been sexually active since their teens and they've never gotten anyone pregnant that they know of. And then "boom" their wives or girlfriends are pregnant. Unless you have had a sperm count and you know for an absolute fact that you are infertile....Then you are fertile. Most men are healthy (including reproductive health), until proven otherwise. As stated above, if you have had no serious illness, such as mumps, or injury to the testicles causing serious swelling then you are probably normal. If you have had unprotected sex on a regular basis for a year with a woman and no pregnancy has resulted then one of you may have a fertility problem. If she is known to be fertile and has had no change in her reproductive health then a semen analysis may be indicated to see if you are normal. Answer: I think you can simply ask your family physician for a fertility test or to have your semen counted.
If you're a woman:To find out the time of month when you're most fertile there are tests that works much like the OTC pregnancy tests. To find out if you're fertile at all you need a thorough medical examination. If you're a man: Leave a semen sample for analysis and you'll get an answer.
By going to a pharmacy and buying a pregnancy test thing and taking the test after about 2-3 week of waiting or u can go to the doctor and ask for a pregnancy test

Unfortunately only a fertilty test could tell you this.
you really cant.. DONT TOUCH THEM. just leave them alone. the mother hen knows if there fertile or not. if there not fertile she'll push them to the side, if they are fertile she will sit on them. but sometimes a pushed aside egg is fertile and also it is always warm as the person said above DON'T TOUCH THEM!!
The one way you can tell if a chicken eggs is fertile is by holding a strong flash light behind it and if you see the embero it is fertile
You can't tell if it's fertile or not based on its weight. The same amount of stuff goes into the egg regardless if it's been fertilized or not.
After 3-10 days of the bird sitting on the egg, take the egg to a strong light and if it has redish vines in it, then it is fertile. If it's just white then its not.
Clearplan ovulation tests are used to help a woman tell when its best in her cycle when she is most fertile. You count two weeks from the start of your period and start using the tests and it will tell you when your two most fertile days are, to try to conceive a baby.
It's possible, but there's no way to tell that isn't insanely expensive and uncomfortable.
Most fertile is the superlative for fertile.
If you wait long enough, every gelding will lose the ability to produce offspring after a few months. A test called a Semen Evaluation can be done to see if he is still fertile.
