Quizplus · Accepted Answer

Vasectomy and tubal ligation are the two contraceptive methods that are generally irreversible and block the gametes from reaching the site where fertilization can occur. Vasectomy involves surgical cutting or tying off of the vas deferens in males, which prevents sperm from being ejaculated with semen. Tubal ligation involves surgical cutting, tying, or sealing off of the fallopian tubes in females, which prevents eggs from reaching the uterus for fertilization. These methods are considered permanent and are suitable for those who do not want to have children or have completed their desired family size.
