Final answer:
Tubal ligation is a permanent form of birth control where a woman's fallopian tubes are surgically sealed or blocked, making it highly effective at preventing pregnancy.
Step-by-step explanation:
The form of birth control referred to in the student's question is tubal ligation. Tubal ligation is a surgical procedure in which a woman's fallopian tubes are sealed or blocked to prevent pregnancy. It is a form of permanent contraception and is considered highly effective. This procedure contrasts with other forms of birth control such as hormonal implants, barrier methods, and natural family planning. Unlike in vitro fertilization (IVF), which is a medical treatment for infertility, tubal ligation is specifically for preventing fertilization from occurring.
