What is the corpus luteum on the left ovary?
In the female reproductive system, the ovarian corpus luteum is an important physiological structure, especially playing a key role in the menstrual cycle and pregnancy. This article will analyze in detail the definition, function and related clinical significance of the left ovarian corpus luteum, and attach structured data for readers to quickly understand.
1. Definition and formation of ovarian corpus luteum
The corpus luteum of the ovary is a temporary endocrine gland formed by the remaining tissue after ovulation of the follicle under the action of luteinizing hormone (LH). Its name comes from its lipid-rich yellow appearance. The main function of the corpus luteum is to secrete progesterone and estrogen in preparation for possible pregnancy.
| stage | duration | Main functions |
|---|---|---|
| follicular phase | about 14 days | follicles mature |
| Ovulation period | 1-2 days | egg release |
| Luteal phase | about 14 days | secretes progesterone and estrogen |
2. The particularity of the corpus luteum of the left ovary
Although there is no essential difference in function between the left and right ovaries, clinical observations have found that:
1. The ovulation frequency of the left and right ovaries is not completely symmetrical, and there may be a phenomenon of dominant ovary
2. The left ovary is adjacent to the sigmoid colon. Pain during corpus luteum rupture may be mistaken for gastrointestinal symptoms.
3. The left ovarian vein returns to the left renal vein, which is different from the right anatomical path.
| Compare items | left ovary | right ovary |
|---|---|---|
| venous return | left renal vein | inferior vena cava |
| adjacent organs | sigmoid colon | appendix |
| Ovulation frequency | about 45% | about 55% |
3. Physiological functions of corpus luteum
The main physiological functions of the ovarian corpus luteum include:
1.progesterone secretion: Maintain changes in the secretory phase of the endometrium and prepare for implantation of the fertilized egg.
2.estrogen secretion: Synergizes with progesterone to regulate the reproductive system
3.pregnancy maintenance: If fertilization is successful, the corpus luteum can be maintained until the placenta is formed (about 10 weeks of pregnancy)
4.feedback regulation: Regulation of the hypothalamic-pituitary axis through hormone levels
4. Diseases related to corpus luteum
Common clinical problems related to the ovarian corpus luteum include:
| Disease name | incidence | Main symptoms |
|---|---|---|
| Luteal insufficiency | 3-10% of infertile patients | Shortened menstrual cycle, infertility |
| corpus luteum cyst | About 2-5% of women of childbearing age | Lower abdominal pain, abnormal menstruation |
| Rupture of corpus luteum | Emergency gynecology 1-2% | Acute abdominal pain, intra-abdominal bleeding |
5. Clinical examination and diagnosis
The evaluation of the corpus luteum of the ovary mainly includes:
1.Ultrasound examination: Transvaginal ultrasound is the preferred method to observe the size and shape of the corpus luteum
2.Hormone testing: Progesterone levels can reflect luteal function
3.basal body temperature: Body temperature increases by 0.3-0.5°C during the luteal phase
4.endometrial biopsy:Assessing endometrial changes during the luteal phase
6. Recent hot topics
According to the analysis of search data on the entire Internet in the past 10 days, popular discussions about the ovarian corpus luteum focus on the following aspects:
| hot topics | Discussion popularity | Related fields |
|---|---|---|
| Luteal corpus function and IVF success rate | high fever | assisted reproduction |
| The progesterone supplement controversy | medium heat | Obstetrics and Gynecology |
| Differential diagnosis of corpus luteum rupture | medium heat | emergency medicine |
| The relationship between exercise and corpus luteum function | low fever | sports medicine |
7. Summary
The left ovarian corpus luteum is an important part of the female reproductive system, and its normal function is crucial to the regulation of menstrual cycles and maintenance of pregnancy. Understanding its anatomical characteristics, physiological functions and related diseases can help women pay better attention to their own reproductive health. When abnormal symptoms occur, you should seek medical treatment promptly for professional evaluation and treatment.
