How does tubal ligation prevent pregnancy?
By blocking the fallopian tubes
By releasing hormones
By preventing ovulation
By thickening cervical mucus
Tubal ligation, also known as getting "tubes tied," is a surgical procedure that involves blocking or sealing the fallopian tubes, which are the pathways that carry eggs from the ovaries to the uterus. This blocking or sealing prevents sperm from reaching the eggs and fertilizing them, which ultimately leads to preventing pregnancy. Tubal ligation is considered a permanent method of birth control as the fallopian tubes are permanently altered and cannot be easily reversed.
Option 1 is the correct answer.
