a) True
b) False
View Answer

Answer: a
Explanation: Progestogen and progestogen-estrogen contraceptives work by preventing the release of egg or by inhibiting the entry of sperm into the fallopian tube or by preventing fertilization. Hence they should be administered within 72 hours of coitus. After 72 hours, the chances of egg being fertilized are very high.
