Vaginal ring: Learn more about this contraceptive method

The vaginal ring is a combined hormonal contraceptive method just like the birth control pill and, although it is a small object that should be inserted through the vaginal canal, it is not a barrier method like the diaphragm and female and male condoms.

Like the pill, the vaginal ring depends on the woman to achieve its high contraceptive effectiveness. What differentiates the ring and the pill is the way hormones are released and the likelihood of making mistakes during use. We consulted the gynecologist and obstetrician of the Porto Alegre Hospital das Clínicas, Murilo de Lima Brazan (CRM-SP: 161709), to give more details about this method.

What is the vaginal ring?

The vaginal ring is a flexible, transparent, smooth-porous, non-absorbent silicone ring that is non-absorbent. Are its shape and size designed to facilitate insertion into the vaginal canal as it must be handled and inserted by the woman herself? they are about 5 cm in diameter and 4 mm thick.

It is a hormonal contraceptive method, meaning it works by releasing hormones into the woman's body. Obstetrician and gynecologist Dr. Murilo de Lima Brazan explains that the ring is considered a combined method because it combines the use of two female hormones: progesterone and estrogen, both found in birth control pill formulas.

How does the vaginal ring work?

The ring works by releasing the hormones progesterone and estrogen directly into the bloodstream. This prevents the woman from ovulating and increases the thickness of the cervical mucus, making it difficult for sperm to rise. Like the birth control pill, does the ring release hormones for 21 days (though some birth control pills may contain 24 active pills) and ask for a break? that may or may not be respected? 7 days, when the woman removes the ring and replaces it with a new one.

Dr. Brazan confirms that wearing the ring does not dispense with the use of condoms because the method does not prevent the transmission of sexually transmitted infections, STIs such as HIV, HPV, Hepatitis B and C, syphilis, etc. And it states that the ring is only recommended for women who have had sex with vaginal penetration, as it is inserted similar to an internal tampon.

Understanding how the method works is the best way to know if it is the right method for you. When in doubt, always consult a gynecologist.

How to use the vaginal ring?

For the first use it is advisable to instruct a gynecologist about the best day to insert the ring. To place the ring just squeeze it between the thumb and forefinger, forming an image similar to an 8, and insert it into the vaginal canal vertically until it reaches a flexible and very sensitive region just below the cervix, which will prevent discomforts.

The ring should be in this position for 21 days. After this period, it must be withdrawn. The woman then has two options: replace with a new one immediately, inhibiting menstruation; or replace after 7 days, creating the interval at which she will menstruate.

The appearance of the vaginal ring is similar to that of the diaphragm, but do not confuse them! They are completely different methods. Brazan explains that the diaphragm is a barrier method and works by physically preventing contact between sperm and egg, while the ring acts chemically to prevent ovulation. Thus, even in unprotected sex, the possibility of fertilization is very low (0.3%).

The gynecologist also states that there is no need to use another contraceptive method concurrently with the vaginal ring, except condoms. Because it is highly effective if used correctly, it is not necessary to associate it with barrier methods or spermicides, especially because the effectiveness of spermicides is one of the lowest among contraceptives.
