How does it work? According to the FirstResponse Website, this fertility test measures the amount of Follicle Stimulating Hormone, (FSH), in your urine. FSH is a hormone that is directly connected to your ovaries and egg production. It tells your body to produce an egg. If your levels are normal, you have enough eggs to consider yourself fertile. If your FSH is elevated, that means your body is producing more of the hormone to convince your body to prepare and release an egg, meaning you don't have very many or have a limited supply. Wow, betcha never realized your urine could tell you so many things!
How and when do you take it?
On day 3 of your cycle. So, you should take this while on your period. This is the prime time to take this test. Hold it in your urine stream for 5 seconds, replace cap, and wait 30 minutes. Yes, it's longer than a pregnancy test, but I think this process is a little more in-depth. After the 30 minutes have passed you will see either one line or two. This is one test where you want to see only ONE line! That means your FSH levels are normal and you have enough eggs to be considered fertile. If you see two lines, it means there is an elevated amount of FSH and so you may have a low supply of eggs and you might consider seeing a fertility specialist.
Does it Work?
Now that's the million dollar question. I think it accurately detects the FSH hormone. I don't it lies about that in it's claim to 95% accuracy. I think that's true. However, not all fertility issues lie in egg production. There several things that contribute to infertility such as PCOS, Endometriosis, even being over/underweight, low progesterone levels, and so much more. And according to www. MedicineNet.com only 1/3 of infertility cases are because of female issues.
Would I Recommend?
If you are healthy, have no signs or history of PCOS, Endometriosis, or other things that can interfere with fertility, then I say go for it. If anything it is a way to rule out one possible cause and give you a sense of relief in that department. But I could caution that you take your result with a grain of salt, because just like in a pregnancy test, there could be false positives, or false negatives. If you have $25-40 to spare it couldn't hurt. But if you are doing it to avoid seeing a fertility specialist, it won't save you money in the long run, because you should see one anyways regardless of your result.
I don't think I will buy one though. If you have tried one, please let me know your experience.
