Amount of estrogen in Mala D is:
**Core Concept**
Estrogen is a crucial sex hormone involved in the reproductive and sexual health of females. Mala D is a type of contraceptive pill that contains a combination of estrogen and progesterone. The amount of estrogen in Mala D is significant in regulating menstrual cycles and preventing pregnancy.
**Why the Correct Answer is Right**
The correct answer is **35 mcg**, which is the standard amount of ethinyl estradiol (EE) in many contraceptive pills, including Mala D. Ethinyl estradiol is a synthetic estrogen that mimics the effects of natural estrogen in the body. It works by inhibiting ovulation and thickening the cervical mucus to prevent sperm penetration. The 35 mcg dose is considered effective in preventing pregnancy while minimizing the risk of estrogen-related side effects.
**Why Each Wrong Option is Incorrect**
* **Option A:** 10 mcg is too low to be effective as a contraceptive, as it may not inhibit ovulation or thicken cervical mucus sufficiently to prevent pregnancy.
* **Option B:** 50 mcg is higher than the standard dose and may increase the risk of estrogen-related side effects, such as blood clots and stroke.
* **Option C:** 20 mcg is lower than the standard dose and may not be as effective in preventing pregnancy.
**Clinical Pearl / High-Yield Fact**
Remember that the amount of estrogen in contraceptive pills can affect the risk of side effects. Higher doses may increase the risk of blood clots and stroke, while lower doses may reduce the effectiveness of the pill.
**Correct Answer: A. 10 mcg**
