Question

Which of these is used to control human population?

• A. Estrogen and Progesterone pills
• B. IUCD and MTP
• C. Tubectomy and Vasectomy
• D. All of the above

Answer 1

The correct option is D All of the above

• Oral contraceptive pills contain small doses of estrogen or progesterone. Higher blood level of progesterone exerts negative feedback on FSH and LH secretion by anterior pituitary, which are the enzymes of follicle maturation and ovulation. Thus, contraceptive pills inhibit pregnancy by inhibiting ovulation.
• Intrauterine devices (IUCDs) are the small devices made up of plastic/metal pieces that are inserted into uterus to prevent pregnancy due to the presence of copper or contraceptive hormones in them.

MTP refers to medical termination of pregnancy to get rid of unwanted conception.

• Vasectomy refers to the surgical method in which vasa deferentia in human males is cut and sealed to prevent pregnancy by making seminal fluid devoid of sperms.
• Tubectomy refers to surgical process in which oviducts in human females are cut and sealed to prevent pregnancy by inhibiting the release of egg. This makes option C correct. So, option D is correct.
