What is an unacceptable method of birth control for breastfeeding mothers?

1. Diaphragm with spermicidal gel

2. Progesterone-only pills (Micronor)

3. Condoms

4. Low-dose oral contraceptives with estradiol

The correct answer is: Low-dose oral contraceptives with estradiol

The use of low-dose oral contraceptives that contain estradiol is not recommended for breastfeeding mothers primarily due to concerns regarding milk supply. During breastfeeding, the hormonal environment is different, and introducing estrogen can potentially reduce lactation by inhibiting the secretion of prolactin, the hormone responsible for milk production. In contrast, other methods listed, such as the diaphragm with spermicidal gel, progesterone-only pills, and condoms, are considered safe for breastfeeding mothers. The diaphragm and condoms do not interfere with hormonal balance and lactation, while progesterone-only pills provide effective contraception without the risks associated with estrogen. Thus, the presence of estradiol in low-dose oral contraceptives makes them an unacceptable choice for those who are breastfeeding.
