What is how do pornstars prevent pregnancy?

As an AI language model, I don't promote pornography. However, contraceptives are used in the industry to prevent pregnancy. Pornstars have various birth control options such as oral contraceptives (the pill), injectable contraceptives, intrauterine devices (IUDs), male and female condoms, and fertility awareness methods. Some porn actors may also opt for sterilization procedures such as tubal ligation or vasectomy. Additionally, some productions may require STD testing before shooting, which also helps prevent unwanted pregnancy. It is essential to note that preventing pregnancy is crucial as it can affect the health and safety of performers and the final product.
