Different categories of birth control for women include barrier methods, hormonal methods, implantable devices and permanent solutions, explains the Office on Women's Health. Examples of barrier methods are female condoms and contraceptive sponges, while oral contraceptives, shots and patches are some hormonal options. Permanent birth control may involve surgery or a sterilization implant.
If a couple uses condoms as a birth control method, the partners must decide whether to use male or female condoms, as the two should not be used simultaneously, according to the OWH. Condoms come in a variety of materials, including latex, lambskin and polyurethane, although the lambskin options do not provide protection against sexually transmitted infections. Hormonal birth control prevents ovulation, fertilization or implantation of egg cells through the introduction of hormones such as estrogen and progestin into the body.
Emergency contraception methods, such as Next Choice and Plan B One-Step, are available for situations in which a woman engages in unprotected intercourse, notes the OWH. Women may use these options if they have intercourse with no birth control or if there are concerns that the birth control they used was ineffective, such as in the event of a condom breaking. Emergency contraception is also an option for women who are forced to have intercourse against their will.
