How can you tell if you are fertile?
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.

You can tell 5-7 days after conception by a quantitative beta hcg blood test if your pregnant. You will need to ask your doctor specifically for this test. With a urine test i…t will take about 3 weeks. I think with a urine test they can find out immediately, right?! I know my doctor did!
Answer . You can't. He would have to be medically tested.
Examine his ejaculate under a microscope to see whether there are sperm.

No, unfortunately ther are no signs that an egg has been fertilised, it is not until the fertilised egg reaches the uterus and implants there that there are any detectable cha…nges. Your body will then produce hcg (human chorionic gonadotrophin), a hormone which is produced to sustAI
you egg had to be about 1.5 weeks to tell.............. you take a really bright LED light into a dark room with the egg and you shoudl have some one with you . then you tak…e one hand and make it into a c and join it with your other hand and make a "cup" have ANOTHER PERSON put the egg on your hands and hold it up to the light (wich has to be pointing up) and if you see a "spider" or a fat squiggle that is moving around then its fertile but if it is clear then its not but remember IT HAS TO BE 1.5 TO 3 WEEKS OLD TO SEE IT!!!!
You can tell when they are not grumpy When they are grumpy that mean the are getting their period
You can really only watch if the male fish is/are (depending on species)'going through the motions'. Unfertilised ova will go white within 24/36 hours. Failure to fertilise th…e ova is not neccessarily the fishes fault. Wrong water conditions have been known to prevent fertilisation as have other wrong parameters.
Basically shining a light through it so that you can see what is inside..it is called candling an egg. You can either make your own home rig or buy one. Explaining what to loo…k for is harder than actually seeing pictures...Do a search on candling and eggs and there should be a list of sites ..some actually have real good images of what to look for with explanations. I do it with my flock at home but it is easier to see than explain. once you see you'll get it right.
If you hold the egg up to a candle or light you will be able to see if it is fertile. - If you see veins or dark blobs it is fertile. - If you see nothingness it is infertile.… - This process is called "candling"
if they have been laid, there's a good chance that threy've been fertilized.
You would only know by candling the egg. Brown eggs are a slight bit harder to candle than white ones. Candling means to shine a very strong light into the egg and observe sha…dows within. If there are no shadows or dark areas withing the egg then it either has not started embryo development or is not fertile.
Do you have a Rooster living with Hens? If so, chances are, yes, the eggs will be fertile. If the hen is brooding, meaning she is sitting on top of the egg to keep it warm, th…en it's probably fertile, if not, then it's not fertile. In any case should you have a rooster and a hen together, and the hen lays an egg, and it doesn't brood, then you should keep the egg warm. I think to check just hold the egg up to a light lol.
Its hard to tell at the time of laying, but after a little while you can look at it though a candle light and see if there is anything there.
In order to tell if a chicken egg is fertile you need to crack it open into a bowl. Use a spoon to move around the yolk of the egg. Keep looking until you see a pale dot on th…e yolk. Look closely at it. If it is simply a dot, the egg is infertile. If it is a doughnut shape, it is fertile.
It takes about 28 days for a fertile duck egg to hatch. Hold the duck egg up to a bright light. Usually you can start to see growth within the egg as veins in the embryonic sa…ck that lines the inside of the shell. You "candle" it the same way professional breeders do. Find a small strong flashlight and go into a dark room. Put the light up against the egg and look at the light from the opposite side of the egg. You should see a shadow inside the egg if it is developing a duckling. If you do, get the egg back to the nest ASAP.
