The correct answer is:
☐ estrogen; LH
Explanation:
1. The ovarian cycle is under the control of estrogen and LH (luteinizing hormone).
2. Estrogen is a hormone produced by the ovaries that plays a key role in regulating the ovarian cycle, including the development and release of eggs.
3. LH is another hormone that is responsible for triggering ovulation, the release of the mature egg from the ovary.
4. Together, estrogen and LH work in a coordinated manner to regulate the various stages of the ovarian cycle, such as follicular development, ovulation, and the formation of the corpus luteum.
5. This hormonal interplay is essential for the proper functioning of the female reproductive system and the menstrual cycle.
