HORMONES IN PREGNANCY
hCG
produced bySYNCITIOTROPHOBLAST
IT ACT STIMULUS TO SUSTAIN PROGESTERONE BY CL
STIMULATES LEYDIG CELLS TO PRODUCE TESTOSTERONE N MALE
IT ACT AS IMMUNOSUPPRESENT BY INHIB MATERNAL EFORT TO REJECT FETUS AS FOREIGN(CAN ANYBODY TELL ME OTHER FACTORS WHICH PREVENT REJECTION OF FETUS?)
DETECTED BY RADIOIMMUNOASSAY DETECTED AT 8-9 DAYS FOLLOWIN OVULATION
DOUBLING TIME IS 1.4 -2 DAYS
MAX IS 100-200IU/ML B/W 60-70 DAYS THEN CONC FALLS SLOWLY TO REACH 10-20IU/ML B/W 100-130 DAYS SECONDARY PEAK AT 32WK
HIGH LEVEL R DUE TO-
1 MULTIPLE PREGNANCY
2 H MOLE
3 CHORIOCARCINOMA
4 DOWN'S SYNDROME<SLIGHTLY HIGF LEVELS>
DISAPPEAR FROM CIRCULATION WITHIN 2 WK OF DELIVERY
HPL- HUMAN PLACENTAL LACTOGEN
LEVEL ISE PROGRESSIVELY TILL 35WK WHEN PLATEU CUMS
<5 MICROGRAM/ML AFTER 35 W SUGEST FETAL DISTRESS N NEONATAL ASPHYXIA AFTR DELIVERY
NO LONGR DETECTED AFTER DELVERY
OTHER HORMONES R PS BETA GLYCOPROTEIN HCT CC TRH GnRH
oestrogen- oestriol is most imp form
site of production synctiotrophoblast
LEVELSAT TERM 40-50MG IN 24 HR URINE
