Question

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

Answer 1

fertility awareness.

Step-by-step explanation:

Although the egg is only fecundable about 12 hours after ovulation, sperm can fertilize an egg up to 5 days after the report; therefore, intercourse almost 5 days before ovulation can result in pregnancy. Thus, methods based on the awareness of fertility require a lack of intercourses during the 5 days before ovulation.

The condom will prevent the spermatozoa from reaching and fertilizing the egg (physical barrier).

The contraceptive pills disrupt the hormonal cycle.
