What term describes the situation when the level of one hormone increases the production of another?

Explanation:
Positive feedback occurs when the level of one hormone increases the production of another, amplifying the overall hormonal response. For example, rising estrogen during the menstrual cycle enhances the release of GnRH and then LH and FSH from the pituitary; the increasing LH/FSH promotes even more estrogen production, creating an amplification that leads to ovulation. This contrasts with negative feedback, which dampens the signal to keep hormone levels stable.
