Human chorionic gonadotropin is a reproductive hormone that is most commonly associated with pregnancy and pregnancy test kits in particular. The reason for this is that it forms that basis of most pregnancy tests and the amount of HCG in your urine or bloodstream can signal a positive result on your kit.
Nevertheless, the knowledge about HCG of most women who are trying to conceive end at those two lines. It is only the physicians and www.1hcgdrops.com who know the more complex details of HCG and how it relates to reproduction.
HCG and the Female Reproductive System
Ovulation is process in the female reproductive system wherein a single egg is released. When that egg meets a sperm, fertilization occurs and the fertilized egg soon changes into an embryo.
That embryo needs human chorionic gonadotropin in order to prevent the uterine wall from shedding. The placenta surrounding embryo is responsible for handling this task and releasing the necessary hormone to deter menstruation. The increased levels of HCG will alter the hormonal levels of pregnant women and will be easily detected in both the urine and blood.
HCG and Pregnancy Tests
Pregnancy tests are one of the most easily available over-the-counter products that can help determine if you have high levels of HCG flowing in your urine. The only time that HCG is secreted is when a placenta has actually formed. Therefore, it serves as a reliable gauge of conception.
Nevertheless, there is still the question of how soon you can conduct a pregnancy test to get a reliable result. Taking a test too early can give you a false negative. To get better results, it is best that you learn to familiarize yourself with your cycle.
Conception occurs at the point that egg and sperm meet. However, even when an embryo forms, it does not immediately cause the release of human chorionic gonadotropin. It is only after the embryo has implanted into the uterine wall, that HCG starts to flow in large amounts.
Often, implantation will only occur a few days after the actual conception. The average time for implantation is six days to a week. After that time, HCG doubling time will cause the human chorionic gonadotropin produced by the placenta to double every 2 to three days during the first trimester.
The ever increasing amount of HCG after implantation means that the first pregnancy test is best taken two weeks after sexual contact or ovulation in order to ascertain that you will get the most reliable result. However, there are also some specially designed pregnancy tests that can be used even earlier during the cycle and still yield credible results.
These specifically labelled high sensitivity pregnancy tests can detect even the smallest change or increase in human chorionic gonadotropin in the urine in as early as seven days after ovulation. The average amount of human chorionic gonadotropin in a woman’s urine sample is 20mIU/ml. When it starts to exceed that level, your pregnancy test will likely register a positive result.
However, different women can have differing cycles. This means that the release of human chorionic gonadotropin can vary from one woman to the next. One woman can start releasing the hormone early and another can start releasing it late. Therefore, the first negative result can end up inconclusive.
Aside from conducting follow-up tests 24 hours or 2 days after your first pregnancy test, it is also vital that you only use the first urine sample of the day for your testing. This early morning urine is often the most concentrated sample that can yield the highest level of actual human chorionic gonadotropin flowing in your system.
After getting a positive result on at least two different tests, you can then request an appointment with your preferred physician. He or she can give more follow-up tests that can determine how far along you are in your cycle.
