Incorrect Statement: Progesterone level is high during the post-ovulatory phase of the menstrual cycle.
Explanation:
Menstrual cycle is a series of physiological changes that occur in the female reproductive system in order to prepare it for fertilization and pregnancy. It is regulated by a complex interplay of hormones, such as estrogen and progesterone, that are secreted by different organs at various stages of the cycle.
The menstrual cycle can be divided into three phases:
1. Follicular phase: It starts on the first day of the menstrual cycle and lasts for about 14 days. During this phase, the follicles in the ovary mature and secrete estrogen.
2. Ovulatory phase: It lasts for about 2-3 days and is marked by the release of a mature ovum from the ovary.
3. Luteal phase: It starts after ovulation and lasts for about 14 days. During this phase, the ruptured follicle transforms into the corpus luteum and secretes progesterone.
The correct statement regarding the menstrual cycle is that the progesterone level is high during the luteal phase, which is the post-ovulatory phase of the menstrual cycle. Progesterone is responsible for thickening the uterine lining, preparing it for implantation of a fertilized egg. If fertilization does not occur, the corpus luteum degenerates, and the progesterone levels drop, leading to the shedding of the uterine lining and the start of a new menstrual cycle.
Therefore, option D is the incorrect statement as progesterone level is high during the post-ovulatory phase of the menstrual cycle.
