Can a home sperm test tell whether I'm fertile? Answer From Chandra C. Shenoy, M.D. Answer From Chandra C. Shenoy, M.D. Many products on the market allow at-home testing of semen samples to check fertility. Semen is the fluid ejaculated during an orgasm. A home sperm test can tell whether sperm are present in semen. Some at-home tests also check how well sperm can move. For a home sperm test, you collect a semen sample by ejaculating into a small cup. A home sperm test may be appealing because you can do it in the privacy of your own home. Results are often ready within a few minutes. But home sperm tests have their limits. They typically measure only one factor related to fertility. They also haven't been well studied to see how reliable they are. Some common factors of infertility may be missed by home sperm tests. Having your semen tested by a lab is the best way to know whether you're fertile. This type of test is called a lab semen analysis.

A lab semen analysis checks:

Semen volume

Total number of sperm

Sperm concentration

Percentage of sperm alive in a sample (vitality)

Movement of sperm (motility)

Shape of sperm (morphology)

If you have fertility concerns, ask your health care provider for an infertility checkup. Relying on a home sperm test might lead to delays in getting a diagnosis and starting treatment, if needed.

Does 72% dark chocolate have caffeine?

If you look at a large, 3.5-ounce bar of very dark chocolate (70-85% cocoa), you'll find around 80 milligrams of caffeine. A similar bar of plain milk chocolate averages 20 milligrams of caffeine.

Yes, that tasty bit of chocolate you're about to eat does indeed contain caffeine. But if you're looking for a caffeine boost, you might want to put down that truffle and grab a cup of coffee instead. Experts state that a person would have to eat fourteen regular-sized (1.5-ounce) bars of milk chocolate to get the same amount of caffeine that you'd ingest in an eight-ounce cup of coffee. Dark chocolate does have more caffeine than milk chocolate, but not that much: you'd still have to eat four bars to get the same buzz as a regular cup of joe. Let's take a look at the caffeine in coffee: eight ounces of generic brewed coffee contains around 95 milligrams of caffeine. A sixteen-ounce cup of good coffee – the “grande” size in many coffee shops – has between 200 and 300 milligrams of the stimulant. Even the standard one-ounce shot of espresso from a coffee shop averages 75 milligrams of caffeine. That's a lot of buzz packed into a small volume. So what about chocolate? A one-ounce square of unsweetened baking chocolate contains 23 milligrams of caffeine. If you look at a large, 3.5-ounce bar of very dark chocolate (70-85% cocoa), you'll find around 80 milligrams of caffeine. A similar bar of plain milk chocolate averages 20 milligrams of caffeine. Hot cocoa only has about nine milligrams per eight-ounce cup. All of this means that yes, you may get a little pick-me-up from chocolate, but if you need a strong jolt to keep your eyes open, you're better off with some of our brewed coffee. Either way, stop by our coffee shop in downtown St Paul and test it out for yourself!
