प्रश्न
Give scientific reasons: When an ovum gets fertilized, menstrual cycle stops temporarily in a woman.
उत्तर
In case of fertilisation of the ovum by a sperm, the corpus luteum persists and continues to secrete progesterone in the body thus maintaining its high levels. The presence of progesterone prevents the maturation of another ovum, thus temporally stopping the menstrual cycle.
