Chapter 47: Problem 10

The most effective method to prevent fertilization is: a. the oral contraceptive. b. the IUD. c. the morning-after pill. d. vasectomy and tubal ligation. e. the rhythm method.

Short Answer

Expert verified
The most effective method to prevent fertilization among the given options is vasectomy and tubal ligation. (Option d.)

Step by step solution

01

Consider the options

Take into account each method listed here: oral contraceptive, IUD, morning-after pill, vasectomy and tubal ligation, and the rhythm method.
02

Evaluate effectiveness

Evaluate each method considering factors such as reliability, ease of use, and failure rate. Oral contraceptives, the IUD, and the morning-after pill can have varying rates of effectiveness depending on how they are used. The rhythm method is least reliable as it depends on calculating 'safe' periods within the woman's menstrual cycle. Vasectomy and tubal ligation are surgical procedures that are highly reliable and known to have extremely low failure rates.
03

Choose the most effective method

Given the high reliability and lowest chance of failure, the most effective method at preventing fertilization among the options given would be vasectomy and tubal ligation.
