Question

select the correct answer.

which form of birth control could people use without altering hormonal systems or blocking sperm from fertilizing an egg?

• fertility awareness
• birth control pills
• condom

Explanation:

Analyze the question criteria

The question asks for a method of birth control that does not alter hormonal systems and does not physically block sperm from fertilizing an egg.

Evaluate the options

Using the Contraceptives knowledge point:

• Birth control pills: These contain synthetic hormones (estrogen and progestin) that alter the body's natural hormonal systems to prevent ovulation. Thus, they alter hormonal systems.
• Condom: This is a physical barrier method that works by physically blocking sperm from entering the uterus and fertilizing an egg.
• Fertility awareness: This method involves tracking natural menstrual cycle patterns to identify fertile days and avoiding unprotected intercourse during those days. It does not introduce hormones or use physical barriers to block sperm.

Select the correct option

Fertility awareness is the only option that meets both criteria: it is non-hormonal and does not physically block sperm.

Answer:

• fertility awareness (Correct answer)
• birth control pills
• condom
