Other word for Follicular Phase?
Other word for Luteal Phase?
Hormones that predominate in Follicular phase ?
Hormones that predominate in Luteal phase ?
Granulosa cell function during Follicular Phase?
Respond to ⬆️FSH to ⬆️aromatase activity —> ⬆️Estrogen
Theca cell response in Follicular Phase?
⬆️LH —> ⬆️Testosterone
What happens to the Testosterone secreted by the Theca Cells?
It’s taken up by the Granulosa Cells— ⬆️⬆️Estrogen production
During Follicular Phase, how are LH and FSH inhibited ?
2. ⬆️inhibin B —> ⬇️FSH
⬆️estrogen secretion effect on Granulosa Cells?
What induces LH and FSH surges?
⬆️⬆️Estrogen surge (no longer inhibits LH and FSH after a certain threshold )
The surge of this hormone induces Ovulation?
When does Follicular Rupture occur after LH surge?
24-36 hours later
How does the Follicule prepare before they convert to Luteal Cells?
⬆️FSH + ⬆️estrogen —> ⬆️LH —> ⬆️Progesterone instead of estrogen
The surge of this hormone induces the conversion of theca and granulosa Cells into Luteal Cells?
⬆️⬆️LH—> Luteal Cells —> ⬆️Progesterone
