Introduction

HCG is a marker of early pregnancy, and its levels rise sharply during the early stages of pregnancy, which can be used to assess whether embryonic development is normal. At 30 days of gestation, HCG levels are approximately 500–1,000 U/L; at 35 days, approximately 2,500–6,500 U/L; and at 40 days, approximately 9,000–21,000 U/L.

Generally, a pregnancy blood test report includes two indicators: HCG and progesterone, which should be interpreted in conjunction with gestational age. The specific analysis is as follows:

HCG is a marker of early pregnancy, and its levels rise sharply during early pregnancy, helping to assess whether embryonic development is normal. At 30 days of gestation, HCG levels are approximately 500–1,000 U/L; at 35 days, around 2,500–6,500 U/L; and at 40 days, about 9,000–21,000 U/L. Progesterone is a pregnancy hormone that gradually increases during pregnancy, helping to maintain the pregnancy and support fetal development. Normal levels are generally considered to be greater than 20 ng/mL (large unit) or greater than 60 nmol/L (small unit).

To correctly interpret a pregnancy blood test report, it's important to understand the normal reference ranges for each parameter. If there are any concerns regarding the results, it is recommended to consult a doctor promptly for professional advice.

How does the size of a chocolate cyst affect pregnancy?

The impact of chocolate cysts on pregnancy is not solely determined by size. However, in general, the larger the cyst, the more significant the effect. Cysts with a diameter exceeding 5 cm are usually considered to have an increased negative impact on fertility. Even smaller cysts may interfere with conception if they are located in critical areas or accompanied by specific symptoms. A comprehensive evaluation before pregnancy planning is recommended to determine the cyst's size, location, and ovarian function.
