Introduction:
Antifertility drugs are medications used to prevent pregnancy. They work by inhibiting ovulation, altering the uterine lining, or preventing the fertilization of an egg. Birth control pills, also known as oral contraceptives, are one of the commonly used antifertility drugs. It is important to understand the characteristics and composition of these drugs to make informed decisions about contraception.
Explanation:
The correct option among the given choices is B. Let's discuss each option in detail to understand why.
a) Birth control pills contain a mixture of synthetic estrogen and progesterone derivatives:
This statement is true. Birth control pills generally contain a combination of synthetic estrogen and progesterone derivatives. These hormones work together to inhibit ovulation, thicken the cervical mucus, and alter the uterine lining, making it less receptive to implantation.
b) Both compounds i.e. estrogen and progesterone are vitamins:
This statement is false. Estrogen and progesterone are not vitamins. They are steroid hormones naturally produced in the body. While they play important roles in various physiological processes, they are not considered essential vitamins.
c) Progesterone is supposed to suppress ovulation:
This statement is true. Progesterone, or its synthetic derivatives, is responsible for suppressing ovulation. It inhibits the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which are necessary for the maturation and release of an egg from the ovary.
d) Norethindrone is an example of synthetic progesterone derivative:
This statement is true. Norethindrone is an example of a synthetic progesterone derivative. It is commonly used in birth control pills and other hormonal contraceptives. Norethindrone mimics the actions of natural progesterone in the body and helps prevent pregnancy by suppressing ovulation, thickening cervical mucus, and altering the uterine lining.
Conclusion:
In conclusion, the statement that is not true about antifertility drugs is option B, which states that both estrogen and progesterone are vitamins. Estrogen and progesterone are not vitamins but rather steroid hormones produced in the body. Understanding the composition and mechanisms of action of antifertility drugs is important for making informed decisions about contraception.
