Heterosexual partners who have achieved the number of children they want may consider using birth control to prevent pregnancies. Though there are many forms, each comes with its own pros and cons. Condoms are easy to use, oral contraceptives have various benefits for women, while cervical caps are reusable. However, some people may be allergic to latex in condoms; cervical caps could cause irritation that could escalate into bladder infections; and oral contraceptives have side effects that include nausea, dizziness, and breast pain. Meanwhile, a vasectomy procedure may be preferable to other permanent forms of contraception because it is more cost-effective and this minor procedure has few side effects.
