True statement about Minipill is :
**Core Concept**
The minipill, also known as the progestin-only pill (POP), is a type of hormonal contraceptive that contains only progestin, a synthetic form of the hormone progesterone. It works by altering the cervical mucus, endometrial lining, and ovulation to prevent pregnancy.
**Why the Correct Answer is Right**
The minipill functions primarily by thickening the cervical mucus, making it difficult for sperm to penetrate the uterus. Additionally, it suppresses the growth of the endometrium, reducing the chances of implantation. The minipill also has a minimal effect on ovulation, but it is not the primary mechanism of action. Progestin in the minipill binds to progesterone receptors in the endometrium, leading to the suppression of endometrial growth and changes in the cervical mucus.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the minipill does not primarily work by suppressing ovulation, although it may have a minimal effect.
**Option B:** This option is incorrect because the minipill does not contain estrogen, making it a progestin-only contraceptive.
**Option C:** This option is incorrect because the minipill does not work by causing an abortion or terminating a pregnancy, but rather by preventing implantation.
**Clinical Pearl / High-Yield Fact**
The minipill is a good option for breastfeeding mothers or women with a history of breast cancer, as it does not affect milk production or estrogen levels.
**Correct Answer: B. The minipill contains only progestin, with no estrogen component.**
