How is estrogen produced?
Estrogen is one of the important sex hormones in women. It not only affects the development and function of the reproductive system, but also plays an important role in the bones, cardiovascular and nervous systems. Understanding how estrogen is produced can help you better manage your health. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide a structured analysis of the production process of estrogen.
1. Basic concepts of estrogen

Estrogen is a steroid hormone, mainly including estradiol (E2), estrone (E1) and estriol (E3). They are mainly secreted by the ovaries, placenta and adipose tissue, and to a lesser extent by the adrenal glands and testicles.
| estrogen type | primary source | Main functions |
|---|---|---|
| Estradiol (E2) | ovary | Promote the development of female secondary sexual characteristics |
| Estrone (E1) | Adipose tissue, ovaries | Main forms of estrogen after menopause |
| Estriol (E3) | placenta | Main estrogen during pregnancy |
2. The production process of estrogen
The synthesis of estrogen is a complex biochemical process, which is mainly divided into the following steps:
1. Conversion of cholesterol
The synthesis of estrogen begins with cholesterol. Cholesterol is converted into pregnenolone through a series of enzymatic reactions in the ovaries, adrenal glands and other organs, thereby producing the precursor substance of estrogen.
2. Production of androgens
Pregnenolone is converted into androstenedione and testosterone, the two androgens that are the direct precursors of estrogen.
3. Aromatization
Under the action of aromatase, androstenedione and testosterone are converted into estrone and estradiol. This process is mainly completed in the granulosa cells and adipose tissue of the ovary.
| steps | key enzyme | product |
|---|---|---|
| Cholesterol conversion | cholesterol side chain cleavage enzyme | pregnenolone |
| androgen production | 17α-hydroxylase | Androstenedione, testosterone |
| aromatization | aromatase | Estrone, estradiol |
3. Factors affecting estrogen production
The production of estrogen is affected by many factors, including age, diet, lifestyle and disease. The following are related topics that have been hotly discussed on the Internet in the past 10 days:
1. Age
Estrogen levels are higher in women during adolescence and childbearing age, but after menopause, ovarian function declines and estrogen secretion decreases significantly.
2. Diet
Foods rich in phytoestrogens (such as soybeans, flaxseeds) may regulate estrogen levels in the body. Hot topics recently include the discussion of "whether soy milk increases the risk of breast cancer."
3. Lifestyle
Exercise, stress and lack of sleep can affect hormone balance. Recent research has found that staying up late for a long time may lead to abnormal estrogen levels.
4. Disease
Conditions such as polycystic ovary syndrome (PCOS) and premature ovarian failure can interfere with estrogen production. Recently, “PCOS and infertility” has become a hot topic on social media.
4. The harm of abnormal estrogen
Estrogen levels that are too high or too low can have health consequences:
| Exception type | may be harmful | Hot topics recently |
|---|---|---|
| Too much estrogen | Breast cancer, endometrial hyperplasia | “Contraceptive Pills and Breast Cancer Risk” |
| low estrogen | Osteoporosis, cardiovascular disease | "Hormone Replacement Therapy for Menopause" |
5. How to maintain estrogen balance
Based on recent health hot topics, it is recommended to maintain estrogen balance from the following aspects:
1. Eat a balanced diet
Eat more cruciferous vegetables (such as broccoli), whole grains, and high-quality protein, and limit foods high in sugar and fat.
2. Regular exercise
Moderate aerobic exercise and strength training help regulate hormone levels. The topic of "yoga regulating endocrine" has become a hot topic recently.
3. Manage stress
Chronic stress increases cortisol and suppresses estrogen production. Meditation and deep breathing are popular ways to reduce stress recently.
4. Regular physical examination
Especially women over 35 years old should have their hormone levels checked regularly. Recently, the "Women's Health Screening Guidelines" have attracted widespread attention.
In summary, estrogen production is a finely regulated process that is affected by many factors. Through scientific lifestyle management and regular monitoring, estrogen balance can be effectively maintained and overall health promoted.
