Cyclic menstruation an indicator of normal reproductive phase, extends between:

  • A.Menstruation and Fertilization
  • B.Ovulation and Menstruation
  • C.Menopause and Menarche
  • D.Menarche and Menopause

Answer: D

The reproductive phase extends between menarche and menopause.

Menarche is the first menstruation, at puberty, usually between 10 and 16 years. Menopause is the permanent stopping of menstruation, usually around 45 to 55 years. Between the two, regular cyclic menstruation shows that ovulation and the hormonal cycle are working normally.

'Menopause and Menarche' puts the events in the wrong order. Menstruation and fertilisation, and ovulation and menstruation, are events within one cycle, not the limits of the reproductive phase.
