In artificial insemination, donated sperm is inseminated into woman's uterus through vagina. It is suitable in the following conditions:
  1. The male partner has a very low sperm count.
  2. When sperms are not strong enough to swim through the cervix and up into the Fallopian tubes.
  3. If the female partner is suffering from a condition called unreceptive cervical mucus. In this, the mucus that surrounds the cervix prevents sperm from getting into the uterus and fallopian tubes. Using this technique, the sperm skips the cervical mucus entirely.
  4. It is also suitable, if the man carries a genetic disease and he does not wish to pass on to his children.
So, the correct answer is 'Artificial introduction of sperms of a healthy donor into the vagina'.
