For which of the following is Depo-Provera NOT intended?

Depo-Provera is a hormonal contraceptive that primarily acts as a method to prevent pregnancy. It contains the hormone progestin, which works by inhibiting ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining. While it may have some secondary effects, such as regulating menstrual cycles and providing treatment for certain health conditions like endometriosis, its primary role is contraception.

The option regarding protection against sexually transmitted infections (STIs) is clearly not part of Depo-Provera's intended use. Unlike condoms, which physically block the transmission of infections, Depo-Provera does not provide any barrier or immune response against STIs. Therefore, using Depo-Provera alone does not offer protection against these infections, making this the correct assertion regarding its limitations.
