In the March issue of The Atlantic, Olga Khazan investigates the future of birth control, from remote-controlled implants to a pill for men. The use of contraceptives dates all the way back to 1850 B.C., when women in ancient Egypt used honey, acacia leaves, and lint to block sperm. This two-minute animation traces the history of contraception through the centuries, from sea sponges (500 B.C.), linen sheath condoms (1564), lemon cervical caps (1700), and the “rhythm method” (1920) to modern advancements such as vaginal rings, hormone injections, IUDs, and patches.
