Misunderstanding Hormonal Methods
Students often confuse the functions of injections, implants, and skin patches, thinking they all work in the same way without recognizing that they specifically contain progesterone to inhibit egg maturation.
Clarify that injections, implants, and skin patches all release progesterone, which specifically prevents ovulation by inhibiting the maturation and release of eggs.
