Short Answer Type Questions

Q.1. List some important steps for improving the reproductive health standards in India.
A.1. Following steps can be taken to improve the reproductive health standards in India:

  • Educating the school going children about the sex-related aspects.
  • A legal ban on the checking of the gender of the foetus.
  • Create awareness about sex-abuse and drawbacks of population explosion.
  • Proper infrastructural and professional facilities to attain re[productive health standards.

Q.2. Female gametes are transferred to the fallopian tube in the GIFT procedure. Is it possible to transfer the gametes to the uterus?
A.2. It is not possible to transfer the gametes to the uterus. This is because the gametes cannot survive in the environment of the uterus. They will be degenerated or phagocytosed if transferred directly into the uterus.

Long Answer Type Questions

Q.1. Describe any three assisted reproductive techniques practised to treat infertility.
A.1. Assisted Reproductive Techniques refer to the medical procedures used to treat infertility. Few of the assisted reproductive techniques are:

  • In-vitro Fertilization- In-vitro fertilization involves the steps:

Stimulation of the ovaries by giving human gonadotropins ↓ Retrieving the released eggs ↓ Fertilization of the eggs with the selected sperms. ↓ Development of eggs into embryos under laboratory environment ↓ The embryos are implanted in the uterus of the female

  • Intracytoplasmic Sperm Injection- In this method, one sperm is injected into the egg. But this procedure might damage the egg. The babies might involve defects in the reproductive organs in case of the abnormal Y chromosome.
  • Gamete Intrafallopian Tube Transfer- This method is used in case of fallopian tubes that are functioning properly. In this technique, the eggs and sperms obtained are not fertilized in the laboratory. They are inserted into the far end of the fallopian tube either through the vagina or through the abdomen with the help of a laparoscope.

Q.2. What are the advantages and disadvantages of hormonal contraceptives?
A.2.
Advantages of hormonal contraceptives:

  • This is a highly effective method of contraception.
