Capacitation refers to changes in the

  1. ovum after fertilisation
  2. sperm after fertilisation
  3. sperm before fertilisation
  4. ovum before fertilisation

Answer

(3) sperm before fertilisation

Solution

Capacitation is the series of physiological changes in the sperm inside the female reproductive tract (removal of the coating on the acrosome, increased motility).

Only a capacitated sperm can undergo the acrosome reaction and fertilise the ovum.

∴ Capacitation refers to changes in the sperm before fertilisation.
