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

The right answer is fertility awareness.

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.
