Question

Answer

The growth of corpus luteum is initiated by​ the action of luteinizing hormone(LH) on a mature follicle( preovulatory). During the ovulatory cycles, there is a surge in the progesterone levels that starts before the LH starts to increase.

Answer

Luteinizing hormone causes ovulation. The remaining cells of ovarian follicle are stimulated by LH to develop corpus luteum.

Answer

When an ovarian follicle releases an egg during the ovulatory phase due to LH surge (maximum secretion of LH), the opened follicle closes off, forming  which is called the corpus luteum. The corpus luteum is responsible for producing the hormone progesterone, which stimulates the uterus to thicken even more in preparation for implantation of a fertilized egg.

Answer

The growth of corpus luteum is initiated by:
Explanation:
Corpus Luteum:
- Corpus luteum is a temporary endocrine structure formed from the remnants of the mature ovarian follicle after ovulation.
- It plays a crucial role in the menstrual cycle and early pregnancy by secreting progesterone.
Luteinizing Hormone (LH):
- LH is a hormone released by the anterior pituitary gland.
- It plays a key role in the menstrual cycle by triggering ovulation and the formation of the corpus luteum.
- After ovulation, LH stimulates the ruptured follicle to develop into the corpus luteum.
Initiation of Corpus Luteum Growth:
- The growth of the corpus luteum is initiated by the surge of luteinizing hormone (LH) that occurs around the time of ovulation.
- LH stimulates the remaining follicular cells to transform into the corpus luteum.
- The corpus luteum then begins to produce progesterone, which is essential for preparing the endometrium for implantation of a fertilized egg.
Significance of LH in Corpus Luteum Growth:
- Without the surge of LH, the corpus luteum may not develop properly, leading to inadequate progesterone production.
- This can result in difficulties in maintaining a pregnancy or irregularities in the menstrual cycle.
Conclusion:
- In conclusion, the growth of the corpus luteum is initiated by luteinizing hormone (LH), which plays a crucial role in the formation and function of this temporary endocrine structure in the ovaries.
