2. IVF is a method of helping a woman to have a baby in which an egg is removed from one of her ovaries, fertilized outside her body, and then replaced in her womb. IVF is an abbreviation for 'in vitro fertilization'.

3. Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

4. Gonorrhea symptoms: painful urination and abnormal discharge from the penis or vagina. Men may experience testicular pain and women may experience pain in the lower stomach. In some cases, gonorrhoea has no symptoms.

Syphilis symptoms:The first stage involves a painless sore on the genitals, rectum or mouth. After the initial sore heals, the second stage is characterised by a rash. Then, there are no symptoms until the final stage which may occur years later. This final stage can result in damage to the brain, nerves, eyes or heart.

5. A sudden increase in population in a large amount is called population explosion.

EFFECTS: It leads to migration of people from rural areas to the urban areas causing the growth of slum areas. People live in most unhygienic and insanitary conditions. Unemployment and poverty lead to frustration and anger among the educated youth.
