It is well known that women enjoy varying periods of infertility after childbirth, depending mainly on whether they breast feed. It is also acknowledged that lactating women are infertile for longer periods than those who do not breast feed1–3. To date, what is not so well established is the precise physiological mechanism that regulates this lactational infertility. Several factors seem to be involved, such as:
  1. (1)

    The high levels of plasma prolactin in lactating women4.

  2. (2)

    The influence of the suckling stimulus5.

  3. (3)

    The effect of maternal diet and malnutrition in reducing fertility during the lactational period6.
