11. Infiltration of the chorionic plate by neutrophils is diagnostic of ( mild ) chorioamnionitis. 12. Eventually, the syncytiotrophoblasts come into contact with maternal blood and form chorionic villi. 13. The latter approach depended on administration of estrogen, progesterone and human chorionic gonadotropin. 14. REM photographs of the egg chorionic structure are provided for genera and selected species. 15. Uterine angiogenesis is upregulated by human chorionic gonadotropin and progesterone and downregulated by estrogen. 16. The hormone is called human chorionic gonadotropin. 17. They often surround the cytotrophoblasts, reminiscent of their normal anatomical relationship in chorionic villi. 18. Many home pregnancy tests are immunoassays, which detect the pregnancy marker human chorionic gonadotropin. 19. A chorionic hematoma appears on ultrasound as a hypoechoic crescent adjacent to the gestational sac. 20. Usually associated with markedly elevated levels of Beta-human chorionic gonadotropins ( HCG ).
