Question

If mammalian ovum fails to get fertilized, which of the following events will not take place?

• A. Corpus luteum will disintegrate
• B. Primary follicle starts developing
• C. Progesterone secretion rapidly increases
  
• D. Estrogen secretion further decreases

Answer 1

The correct option is C Progesterone secretion rapidly increases

Progesterone suspends ovulation during pregnancy, maintains foetal connection with the uterine wall and controls development of foetus in the uterus.

If fertilization fails, means no pregnancy so progesterone level decreases to restart the process of ovulation.

So, the correct answer is 'Progesterone secretion rapidly increases'.
