Which statement about hormonal contraceptives is TRUE?

Hormonal contraceptives are known to impact the menstrual cycle, making the statement that they may alter menstrual cycles true. These forms of contraception, which include methods such as birth control pills, patches, and hormonal IUDs, work by introducing hormones into the body that can change the way the ovaries function and affect the uterine lining. As a result, this can lead to changes in menstrual flow, cycle regularity, and even the overall experience of menstruation, including making periods lighter or even absent in some cases.

Regarding the other options, the statement about causing immediate fertility is not accurate; hormonal contraceptives typically prevent ovulation, meaning they do not lead to immediate fertility. The suitability of hormonal contraceptives for everyone is also incorrect as individual health conditions and risks can make them inappropriate for some users. Lastly, the idea that they require no medical consultation overlooks the importance of discussing health history and potential risks with a healthcare provider before starting any form of hormonal contraception. Therefore, it is clear that the alteration of menstrual cycles is a validated and well-known side effect of hormonal contraceptives, making that statement true.
