Pregnancy is one of the most common reasons for a late or missed period. When pregnancy occurs, the body produces human chorionic gonadotropin (hCG). This hormone prevents further ovulation and helps maintain the uterine lining so the fetus can grow. What Is Amenorrhea? Amenorrheais when you st...
The patient underwent an exploratory laparotomy at 18 weeks’ gestational age. A left oophorectomy was performed. Pathology confirmed hyperreactio luteinalis. The remainder of the pregnancy was remarkable for preterm labor and delivery at 35 weeks’ gestational age. At delivery, the hCG level was ...

In early pregnancy, beta human chorionic gonadotropin (βhCG) secreted by syncytiotrophoblasts maintains the corpus luteum, which allows it to continue secreting progesterone until the placenta takes over its function at 7 to 9 weeks of gestation. Progesterone causes secretory changes in the ...

In fact, in a normal pregnancy the human chorionic gonadotropin (hCG) [73], blood pressure [74], and uterine contraction [75], show circadian rhythms. However, few studies has reported a clock gene expression in full-term human placenta and trophoblast cell lines [76,77]. In addition, ...

Conclusion: In normal pregnancies at 11–13 weeks, serum AFP increases with gestational age and is affected by maternal race, weight, smoking status and method of conception. 展开 关键词: First-trimester screening Alpha-Fetoprotein Free β -hCG PAPP-A Pyramid of prenatal care ...
