Which of the following statements is true regarding progestin-only contraceptives?

• A. They are not safe for use in women with cardiovascular disease
• B. They are contraindicated in moderate hypertension
• C. They do not alter the quality or quantity of breast milk
• D. They increase the risk for pelvic inflammatory disease

Answer: (C)

Progestin-only contraceptives, often referred to as the "mini-pill," have been associated with minimal effects on lactation, making it true that they do not alter the quality or quantity of breast milk. This characteristic makes them a preferred option for breastfeeding women, as estrogen-containing contraceptives can interfere with milk supply and composition.

The other statements highlight concerns that are not applicable to progestin-only methods. While there may be caution exercised regarding their use in certain health conditions like cardiovascular disease and hypertension, progestin-only contraceptives are not outright contraindicated for all women with these conditions. In fact, they are often regarded as a safer alternative compared to combination hormonal contraceptives in these populations. Additionally, progestin-only contraceptives have not been shown to be associated with an increased risk of pelvic inflammatory disease when used properly. Therefore, the assertion that they do not affect breast milk and their suitability for use during breastfeeding underlines the importance of understanding their unique properties among various contraceptive options.
