• B. Oxytocin
• C. Progestrone
• D. Oestrogen

Answer 1

Answer: (C)

Progestrone

Progesterone belongs to a group of steroid hormones called as progestogens. It is mainly secreted by the corpus luteum in the ovary during the second half of the menstrual cycle. It plays important roles in the menstrual cycle and in maintaining the early stages of pregnancy. The progesterone prepares the body for pregnancy in the event, that the released egg is fertilised. If the egg is not fertilised, the corpus luteum breaks down, the production of progesterone falls and a new menstrual cycle begins. Hence, progesterone is called as the 'anti abortion' hormone.
