Final answer:
The vaginal ring generally has lower doses of estrogen and progesterone compared to the birth control pill.
Step-by-step explanation:
Both the birth control pill and the vaginal ring are hormonal contraceptive methods that contain estrogens and progesterone. However, the vaginal ring generally has lower doses of estrogen and progestin compared to the pill. The vaginal ring is a thin, flexible ring that is inserted into the vagina and releases the hormones to prevent ovulation and thicken cervical mucus. This method offers convenience as it is only inserted once a month.
