Explanation:
Detailed explanation-1: -If a fertilised egg implants in the lining of the uterus, the corpus luteum continues to produce progesterone, which maintains the thickened lining of the uterus. If pregnancy does not occur, the corpus luteum dies, progesterone levels drop, the uterus lining sheds and the period begins again.
Detailed explanation-2: -Luteal Phase The egg cell released during the ovulation phase, stays in the fallopian tube for 24 hours. If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.
