HCG levels not only signal pregnancy but are also a way to measure whether a pregnancy is developing correctly.

Very low HCG levels may point to a problem with the pregnancy, an ectopic pregnancy , or warn that a miscarriage could happen. Rapidly rising HCG levels can signal a molar pregnancy when a uterine tumor grows. HCG levels stop rising late in the first trimester.

This leveling out may be why many women experience relief from pregnancy symptoms, such as nausea and fatigue , around this time. Many women have very low levels of HCG in their blood and urine when they are not pregnant.

HCG tests detect elevated levels. Tests may not detect pregnancy until HCG has risen to a certain level. This requirement means tests that detect lower levels of HCG may diagnose pregnancy earlier. Blood tests are typically more sensitive than urine tests. However, many home urine tests are highly sensitive.

A analysis found that four types of home pregnancy tests were able to detect HCG levels up to 4 days before the expected period, or about 10 days after ovulation for many women. People must read the urine test instructions and follow them carefully. Most tests use lines to show when a test is positive. The test line does not have to be as dark as the control line to be positive. Any line at all indicates the test is positive. Test strips can change color as they dry.

Some people notice an evaporation line after several minutes. This is a very faint line that may look like a shadow. An individual must check the test within the time frame the instructions indicate, usually 3 minutes.

Tests read after 10 minutes may be inaccurate or show evaporation lines. Learn more about evaporation lines here. HCG tests are more likely to produce false negatives than false positives. The longer after implantation a person waits to do the test, the more accurate it will be. HCG levels begin rising when an embryo implants in the uterus. Implantation usually happens a week or so after ovulation. Our data also imply that hCG treatment for patients with IHH presenting with micropenis results in a satisfactory gain in penile length.

Keywords: Human chorionic gonadotropin, Micropenis, Testosterone. Patients A total of 20 male patients with IHH who met the criteria for micropenis were included in this study. Methods 1 Clinical and laboratory assessment Testis volume was assessed by using the Prader orchidometer. Open in a separate window.

Increase in serum testosterone after hCG treatment The mean serum testosterone level was significantly increased after hCG treatment. Increase in penile length after hCG treatment Penile length was measured with the penis flaccid and fully stretched. Increase in testicular volume after hCG treatment The mean testicular volume measured by orchidometer increased significantly as well after hCG treatment. References 1.
