Practice question Researchers measured relative hormone concentration during one menstrual cycle and recorded what happened in an ovary.
Hormone measurements and ovarian observations | Time in the cycle | Recorded concentration and observation |
|---|
| Days 3–9 | FSH rises from 4 to 10 arbitrary units while one egg matures. |
|---|
| Day 14 | LH rises from 6 to 28 arbitrary units as the mature egg leaves the ovary. |
|---|
Use the measurements and observations to describe the roles of FSH and LH.
