What is the surgical procedure known as sterilization aimed at?

Regulating menstrual cycles
Preventing fertilized eggs from implanting
Cutting or tying tubes in the reproductive system
Increasing the likelihood of conception

The correct answer is: Cutting or tying tubes in the reproductive system

The surgical procedure known as sterilization is aimed at cutting or tying tubes in the reproductive system. This procedure is designed to permanently prevent pregnancy by blocking the pathways through which sperm and eggs travel, thus preventing fertilization. In women, this often involves the fallopian tubes, and in men, it typically involves the vas deferens. By performing this procedure, individuals are making a long-term decision about their reproductive health. The other options do not accurately describe the primary goal of sterilization. Regulating menstrual cycles is related to hormonal treatments, while preventing fertilized eggs from implanting pertains more to contraceptive methods rather than sterilization itself. Increasing the likelihood of conception is contrary to the purpose of sterilization, which is to prevent it altogether.
