Q

Ferning (Fern Test)

A

+amniotic fluid → Rupture of membranes (detects onset of labor)

  • Occurs due to the presence of sodium chloride in cervical mucus under estrogen effect when the mucus dries on a glass slide. When high levels of estrogen are present, just before ovulation, the cervical mucus forms fern-like patterns due to crystallization of sodium chloride on mucus fibers. Also known as “arborization”.
  • Disappearance of ferning suggests ovulation (when progesterone is dominant hormone)
  • Persistence of ferning throughout menstrual cycle suggests anovulation

Q

Theca cells & granulosa cells produce:

A
  • Theca: Androstenedione (estradiol precursor)
  • Granulosa: Estradiol (conversion from aromatase)
  • Estradiol is later converted to estrogen, which is released from follicle during follicular phase;
  • Estrogen peaks at end of follicular phase causing LH surge
  • Progesterone is released from corpus luteum
  • Progesterone is elevated during luteal phase (following ovulation)
  • Hypothalamus (GnRH) → Anterior Pituitary (LH/FSH) → Ovary (theca/granulosa cells) → androstenedione, estrogen, progesterone (LH)
  • Males:
    • LH → Leydig → T → inhibits hypothalamus & AP
