Endocrine: Progesterone Flashcards
Ovulation in females
Evaluation fertility
Progesterone
Hormones that maintains pregnancy
Progesterone
Increased in Estradiol
Thickening of Uterine wall
Follicular Phase
Increased LH induced by estrogen
Ovulation (day 14)
- Formation of Corpus luteum
- No fertilization
- Decreased synthesis of Estrogen and progesterone
Luteal Phase
Test For Menstrual Cycle Dysfunction and Anovulation:
LH
FSH
Progesterone
Estrogen
Test for Female Fertility:
HCG
Prolactin
FT4
TSH
LH
E2
Progesterone
Precocius puberty
Infertility and Irregular Menses
Postmenopausal bleeding
Hyperestrinism
Testicular atrophy
Breast enlargement in male
Hyperesterinism
Ovarian Insufficiency
Delayed Puberty
Amenorrhea
Turner’s Syndrome
Hypoestrinism
partial or complete loss of one of the two X chromosomes
Turner’s Syndrome
Prevents menstrual cycle from occuring
Hyperprogesteronemia
Causes infertility, abortion of fetus
Hypoprogesteronemia
During Pregnancy:
Increased in 1st trimester
B-HCG
During Pregnancy:
Increased in 2nd trimester
Estrogen (Estriol)
During Pregnancy:
Increased in 3rd trimester
Progesterone
Triple Test consists of
A1-fetoprotein
Unconjugated Estriol
B-HCG
Triple tests helps to estimate the risk for
Trisomy 21 (Down Syndrome)
Triple Test; Definitive testing would follow
Amniocentesis
Chromosome Analysis
It synthesizes and secretes progestrone, estrogen, human chorionic gonadotropin, HPL
Placenta
prolongs viability of corpus luteum
HCG
detect pregnancy
HCG qualitative
Hydatidiform mole, choriocarcinoma, pre-eclampric toxemia
Increased HCG
THREATENED ABORTION, Ectopic Pregnancy
Decreased HCG
Pre-term labor
Fetal fibronectin
Produce estrogen and progesterone
HPL
Decreased HPL
Placental malfunction
Potential Fetal Distress
Glycoprotein secreted by syncytial trophoblast
Pregnancy-associated Plasma Protein A
Needed for implantation; maintain healthy placenta
Pregnancy-associated Plasma Protein A
Low Level of Protein A
Down Syndrome
High Level of Protein A
Twin pregnancy
