Question

If mammalian ovum fails to get fertilized, which one of the following is unlikely ?

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

Answer 1

Answer: (C)

Primary follicle starts developing

Answer 2

The primary follicles are the initial stage of follicle development in the ovary. If fertilization does not occur, the primary follicles would not typically start developing immediately. Instead, the cycle would likely follow the natural progression, with the corpus luteum disintegrating, estrogen secretion decreasing, and progesterone secretion rapidly declining. If fertilization does not occur, the ovarian cycle typically proceeds towards the preparation of a new follicle for ovulation in the subsequent menstrual cycle.

So, the correct option is (C): Primary follicle starts developing
