Its delicate balance of hormone production and destiny intertwines with the very essence of reproduction, captivating researchers and enthusiasts alike.
Join us on a captivating journey into the enigmatic realm of the corpus luteum and uncover its secret dances within.
corpus lutein
The corpus luteum is a temporary endocrine structure that forms in the female ovaries after ovulation.
It is the remains of the ovarian follicle and plays a crucial role in the reproductive process.
The corpus luteum produces hormones such as progesterone, estradiol, and inhibin A, which are involved in the development and maintenance of the endometrium and the softening of the pubic symphysis.
If the egg is fertilized, the corpus luteum continues to secrete progesterone to support pregnancy.
However, if the egg is not fertilized, the corpus luteum degenerates into scar tissue, leading to menstruation.
The corpus luteum’s function is regulated by the release of gonadotropin-releasing hormone and luteinizing hormone.
Its size can range from under 2 cm to 5 cm in diameter, and it is formed from follicular cells.
The yellow color of the corpus luteum is due to the presence of carotenoids, particularly lutein, which are concentrated from the animal’s diet.
Key Points:
- Corpus luteum is a temporary endocrine structure that forms in the ovaries after ovulation.
- It produces hormones like progesterone, estradiol, and inhibin A.
- These hormones are involved in the development and maintenance of the endometrium.
- If the egg is fertilized, the corpus luteum continues to secrete progesterone to support pregnancy.

Pro Tips:
1. The term “corpus luteum” is derived from Latin and translates to “yellow body,” referring to the yellow color it takes on due to its high concentration of lipids.
2. Corpus luteum is only found in females, specifically in their ovaries. It plays a crucial role in the female reproductive system by producing hormones necessary for pregnancy.
3. After the release of an egg, the empty ovarian follicle transforms into the corpus luteum under the influence of luteinizing hormone (LH).
4. Corpus luteum produces progesterone, a hormone essential for maintaining a healthy pregnancy by promoting the thickening of the uterus lining and preventing the shedding of the uterine wall.
5. If pregnancy does not occur, the corpus luteum starts to regress around the 12th day after ovulation, which leads to a decrease in progesterone levels. This regression marks the start of the menstrual cycle.

Production Of Progesterone, Estradiol, And Inhibin A
The corpus lutein plays a key role in hormone production, including progesterone, estradiol, and inhibin A. Specifically, progesterone is important for preparing and maintaining the endometrium, which is essential for successful implantation of a fertilized egg. Estradiol, a type of estrogen, is involved in regulating the menstrual cycle and influencing secondary sexual characteristics in females. Additionally, inhibin A helps to regulate the secretion of follicle-stimulating hormone (FSH) and plays a role in controlling ovarian function.

Formation And Size Range Of Corpus Luteum
After ovulation, the follicular cells of the ovary undergo a transformation, forming the corpus luteum. The size of the corpus luteum can vary, ranging from under 2 cm to 5 cm in diameter. This range depends on various factors, including the individual’s hormonal status and the specific stage of the menstrual cycle.
- The corpus luteum is formed from the follicular cells of the ovary after ovulation.
- Its size can range from under 2 cm to 5 cm in diameter.
- Factors such as hormonal status and the stage of the menstrual cycle influence the size of the corpus luteum.
Role In Inhibiting Release Of Hormones
The corpus luteum regulates the release of certain hormones in the female reproductive system. It inhibits the release of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH). By doing so, it maintains the delicate balance of reproductive hormones, ensuring the proper functioning of the reproductive system.
Formation And Development From Follicular Cells
The corpus luteum is a structure that develops from the follicular cells surrounding the egg during the menstrual cycle. These cells undergo a transformation, resulting in the formation of a yellowish structure called the corpus luteum. It is worth mentioning that the corpus luteum obtains its yellow color from carotenoids, specifically lutein, obtained from the animal’s diet.
Metabolic Activity And Production Of Antioxidant Enzymes
Aside from hormone production, the corpus luteum is involved in various metabolic activities. During its development, there is an increase in the enzyme P450scc, which plays a crucial role in the production of progesterone from cholesterol. Additionally, the corpus luteum produces antioxidant enzymes, which help protect the reproductive tissues from oxidative stress and damage.
Function In Endometrium Development And Pubic Symphysis Softening
The corpus luteum plays a crucial role in the development and maintenance of the endometrium, the inner lining of the uterus. It promotes the optimal growth and preparation of the endometrium for potential implantation of a fertilized egg. Additionally, the corpus luteum secretes the hormone relaxin, which is responsible for softening the pubic symphysis and facilitating easier childbirth.
Degeneration Or Continued Secretion Based On Fertilization
The fate of the corpus luteum is dependent on fertilization. If the egg is not fertilized, the corpus luteum will degenerate into scar tissue after approximately 10-14 days, resulting in menstruation. However, if fertilization occurs, the corpus luteum continues to secrete progesterone, which is vital for the maintenance of pregnancy, until the placenta takes over the production of this hormone.
- If the egg is not fertilized: corpus luteum degenerates into scar tissue, leads to menstruation.
- If fertilization occurs: corpus luteum continues to secrete progesterone.
- Progesterone is vital for the maintenance of pregnancy.
“The fate of the corpus luteum depends on fertilization.”
Influence Of Prostaglandins And Placenta In Progesterone Production
Prostaglandins play a significant role in the regulation of the corpus luteum. They can cause the degeneration of the corpus luteum, leading to the abortion of the fetus if fertilization has occurred. In placental animals like humans, the placenta takes over the production of progesterone later in pregnancy. This shift in progesterone production ensures the ongoing support and development of the pregnancy.
To summarize:
- Prostaglandins regulate the corpus luteum.
- Prostaglandins can cause the degeneration of the corpus luteum and abortion if fertilization has occurred.
- In humans, the placenta takes over progesterone production later in pregnancy to support and develop the pregnancy.
Clinical Aspects Including Corpus Luteum Cyst And Menstruation
Pathologies associated with the corpus luteum include the formation of corpus luteum cysts. These cysts occur when the corpus luteum fails to regress after its usual lifespan, leading to the accumulation of fluid and enlargement of the structure. Corpus luteum cysts generally resolve spontaneously but can cause pain and other symptoms. Additionally, the degeneration of the corpus luteum is a crucial step in the menstrual cycle, leading to menstruation.
In conclusion, the corpus luteum, or corpus lutein, is a temporary endocrine structure found in the female ovaries. It plays a vital role in hormone production, reproductive processes, and the development and maintenance of the endometrium. The corpus luteum’s functions are significant in both the preparation for a potential pregnancy and the regressive process if fertilization does not occur. Its intricate involvement in various aspects of the reproductive system highlights its significance in female fertility and overall reproductive health.

You may need to know these questions about corpus lutein
What does corpus luteum do?
The corpus luteum is a vital structure located within the ovaries, responsible for ensuring the optimal conditions for fetal growth in the uterus. One of its primary functions is to secrete progesterone, a hormone essential for preparing the uterus for pregnancy. However, once its role in progesterone production is complete, the corpus luteum naturally diminishes.
What is lutein in corpus luteum?
Lutein in the corpus luteum refers to the presence of yellow pigment and lipids within the lutein cells. These cells develop after ovulation, accumulating the saffron-yellow color and lipids within the granulosa cells of the follicle. As the size of the corpus luteum can vary greatly, the amount of lutein present can also vary, providing an interesting characteristic to this hormone-producing structure.
Is a corpus luteum cyst normal?
Yes, a corpus luteum cyst is a normal occurrence in a woman’s ovaries. This harmless, fluid-filled mass forms on the corpus luteum, which is a cluster of cells that develops after the release of an egg each month. It plays a crucial role during pregnancy and is generally considered a regular part of the menstrual cycle.
What causes a corpus luteum cyst?
A corpus luteum cyst is caused by the alterations that occur in the ovarian follicle following the release of an egg. When the escape opening of the follicle becomes sealed, the build-up of fluid inside gives rise to the formation of a corpus luteum cyst. This cyst is a result of the natural hormonal changes that take place during the menstrual cycle, and while it is usually harmless and resolves on its own, it may sometimes cause discomfort or complications.
