A continuation of Birth Control Methods and Techniques. This guide will introduce you to the latest birth control methods, while shedding some light on the positive and negative aspects of particular birth control methods
All barrier methods work as blocking devices to prevent sperm from traveling to the uterus; thus, preventing fertilization and pregnancy. Most barrier devices are inserted into a woman’s vagina before intercourse. The notable exception to this is the condom, which is worn over the penis during sex. Barrier methods, generally speaking, are successful birth control options, though some people consider barrier devices a hassle and an inconvenience, as an obstacle to spontaneity. For those women sensitive to birth control pills, barrier methods are a reliable choice of birth control. Important note: Do not use oil-based or silicone-based personal lubricants with barrier devices made of silicone or rubber. Both types of lubricants could potentially damage the barrier device, limiting the device’s effectiveness.
Diaphragms
Diaphragms are made of silicone-rubber material in the shape of a dome. This birth control device must be inserted before intercourse, behind the pubic bone and covering the cervix, preventing sperm from journeying through the cervix to the uterus. Women interested in using a diaphragm must visit their local health practitioner for a pelvic examine. During this exam, the doctor measures the vagina to find an appropriately sized and comfortable diaphragm. Doctors should check patients’ diaphragm measurements once a year. Pregnancy, weight loss or gain, or recent childbirth can alter how a diaphragm fits inside of the vagina.
Spermicide—a foam, jelly, or cream substance that kills sperm—should be used with diaphragms for secondary protection. Apply spermicide inside of the diaphragm cup and around the edges of the diaphragm. To insert the diaphragm, you squeeze the diaphragm into a half circle. Slowly push the diaphragm inside of your vagina until deeper movement is impossible, and then gently fold the rim directly behind the pelvic bone, where it will rest during nooky. You shouldn’t be able to feel the diaphragm. If you can feel it, it might not be inserted correctly. Be sure to adjust the diaphragm’s position for greater protection. Women should leave the diaphragm inserted for at least six hours after intercourse for the best results.
However, be extremely careful when inserting or removing a diaphragm—the slightest fingernail nick or puncture of the diaphragm makes the device less reliable. Never leave a diaphragm in the open and always wash it carefully. Always check your diaphragm for rips, tears, holes, or punctures before using it. Diaphragms are effective birth control devices when properly used and cared for, and are relatively inexpensive in comparison to other birth control methods. If you have any questions about how the device fits inside of you or how to correctly insert and remove it, visit with your health practitioner for specific instructions and professional suggestions.
Positives
- Painless, comfortable insertion, use, and removal
- Inexpensive, reusable birth control device
- Presence doesn’t interfere with intercourse
- Future fertility unaffected
Negatives
- Does not protect against sexually transmitted diseases
- Toxic Shock Syndrome results from prolonged insertion (twenty-four hours or more)
- Possible bladder infections
Cervical Caps
Cervical caps (widely recognized as the FemCap in the United States) works similarly to a diaphragm, though it is much smaller and should offer a snugger fit when inserted properly. Doctors prescribe silicone-rubber cervical caps according to three factors—all of which are related to pregnancy or lack thereof: If a woman has never been pregnant, a doctor will prescribe a 22 millimeter cervical cap; or a 26 millimeter cervical cap for women who have been pregnant but did not deliver the baby vaginally; or a 30 millimeter cervical cap for women who did deliver a baby vaginally. The differences in cervical cap sizes, as you can see, are in accordance with vaginal changes that occur during pregnancy and delivery.
