The sex hormone estrogen is crucial to your reproductive and sexual well-being. Natural fluctuations in estrogen levels occur during menstruation and decrease after menopause. Elevated or decreased estrogen levels over time may indicate a medical problem that needs to be addressed by your doctor.

Estrogen is one of the two sex hormones that are usually linked to cisgender women, transgender men, and nonbinary people with vaginas who were assigned female at birth (AFAB). Estrogen and progesterone are essential to your reproductive health. Estrogen is necessary for secondary sexual characteristics (breasts, hips, etc.) to develop as well as for menstruation, pregnancy, and menopause to occur.

This article provides a deeper dive into estrogen, exploring its function, the effects of estrogen fluctuations, and its clinical applications.

Estrogen Action

Importance of Estrogen

Estrogen is crucial to the function of many other bodily systems as well. That’s why, despite AFAB people having the highest estrogen levels, both sexes produce estrogen. Both male and female reproductive systems depend on the hormone estrogen. It helps maintain a healthy reproductive system and breasts in women.

Estrogen helps with brain function, bone health, heart health, and many other important body functions. Most people are aware of its importance for female sexual and reproductive health in conjunction with progesterone.

Estrogen is made in the ovaries, adrenal glands, and adipose tissue. This hormone is present in both male and female bodies, but it is produced at a higher rate in the latter.

Different forms of Estrogen 

Several distinct estrogens exist, and they are:

Estrone

One of the female sex hormones is estriol. After menopause, levels of this weakest form of estrogen tend to rise. Estrone, like the other estrogens, helps women’s sexuality flourish. Either low or high levels of estrone can result in symptoms like irregular bleeding, fatigue, and mood swings.

Estradiol

Both sexes produce estradiol, which is the predominant form of estrogen in women of childbearing age.

Acne, decreased libido, brittle bones, and mental health issues have all been linked to elevated estradiol levels. Cancer of the uterus and breasts may develop at very high levels. However, low concentrations have been linked to increased body fat and cardiovascular disease.

Estriol

High levels of the estrogen hormone estriol are produced during pregnancy. This hormone promotes normal uterine development and function. In addition, it gets their body ready for labor and breastfeeding. If the mother’s estriol levels are abnormally high or low, it could be a sign of trouble for the developing baby. Estriol is a hormone therapy option for providers looking to alleviate menopause symptoms.

Estriol levels increase during pregnancy, which is good for the mother and the developing baby. Pregnancy is associated with the highest levels. They aid in the physical preparation for childbirth. Estriol is naturally produced by everyone. In contrast, non-pregnant people have negligible levels. Estriol is also known as oestriol and E3.

Estrogen role In women’s and DFAB’s reproductive health

Like other hormones, estrogen serves as a chemical conduit. It controls when things happen in the body that is important for sexual and reproductive health. These activities lead to substantial alterations in your body.

Puberty: 

Puberty is associated with an increase in estrogen levels. The increase is responsible for the development of secondary sex features such as breasts as well as changes in overall body composition (like curves).

When estrogen is present, sexual activity is less awkward, regardless of when a woman is in her menstrual cycle. The vaginal walls are kept thick, elastic, and lubricated, which makes for less painful sexual penetration.

Menopause:

The premenopausal period, or perimenopause, is characterized by a decrease in estrogen levels. The transition to menopause, known as perimenopause, can take years. When menstruation stops for a full year, a woman is considered to have entered menopause. The average age of onset is 51. As estrogen levels decline during menopause, ovulation stops. Symptoms like vaginal dryness, mood swings, night sweats, and hot flashes may occur as estrogen levels drop.

During menopause, estradiol (E2) is converted to estrone (E1) as the primary estrogen in the body.

Estrogens’ function in male reproduction

The reproductive health of those who are anatomically male at birth (AMAB) is also impacted by estrogen. Estrogen affects sex drive and the ability to get an erection and make sperm in cisgender men, transgender women, and nonbinary people with penises.

A lack of estrogen can dampen your desire to have sex. Infertility and erection problems can result from taking too much of it. Gynecomastia, or enlarged breasts, can be brought on by an excess of estrogen.

Consult an endocrinologist or a functional medicine specialist if you were assigned male at birth and are concerned about your estrogen levels.

Estradiol:

Estradiol is the predominant form of estrogen in women of childbearing age, and it is produced by both sexes.

High levels of estradiol have been linked to acne, less libido, weak bones, and mental health problems. Cancer of the uterus and breasts may develop at very high levels. However, low concentrations have been linked to increased body fat and cardiovascular disease.

Estriol:

High levels of the estrogen hormone estriol are produced during pregnancy. This hormone promotes normal uterine development and function. In addition, it gets their body ready for labor and breastfeeding. If the mother’s estriol levels are abnormally high or low, it could be a sign of trouble for the developing baby. Estriol is a hormone therapy option for providers looking to alleviate menopause symptoms.

Estriol levels increase during pregnancy, which is good for the mother and the developing baby. Pregnancy is associated with the highest levels. They aid in the physical preparation for childbirth. Eestriol is naturally produced by everyone. In contrast, non-pregnant people have negligible levels. Estriol is also known as oestriol and E3.

The hormones estrogen and testosterone are commonly referred to as “female” and “male” hormones, respectively. But both hormones can be found in people of both sexes. So, the differences between the sexes are not qualitative but quantitative, because they are caused by different levels of hormone production and different ways that steroid hormone receptors are expressed.

Serum oestradiol levels in women are significantly higher than those in men, but men can have estrogen levels as high as 250 pg/mL in their rete testis fluids.  Although it is well known that estrogen receptors are expressed in male reproductive tissues, the precise function of estrogen in male reproduction is not well understood.

When this important process is stopped, the sperm enter the epididymis in a diluted state instead of a concentrated one. This makes it impossible for the man to have children. This finding adds to the growing body of evidence implicating environmental Estrogen s in declining sperm counts and other male reproductive outcomes.

Influence of estrogen

What Is The healthy level of estrogen?

Estrogen levels fluctuate during the course of a person’s life. The changes are typical. During puberty, estrogen levels grow, and they fall as menopause approaches. During ovulation, estrogen levels naturally rise to help the body get ready for pregnancy. During your period, when pregnancy adjustments are no longer required, it is natural for levels to drop.

Low or high levels on a regular basis may be a sign that your provider needs to address a problem.

Consequences of low estrogen levels

When estrogen levels drop, menopause is usually not far behind. Infertility, nutritional deficiencies, medical conditions like Turner syndrome, etc. can all contribute to a lack of estrogen.

Other roles of estrogen  apart from reproduction

Estrogen governs crucial processes in the skeleton, heart, and brain that have an effect on your health as a whole. Estrogen influences;

  • levels of cholesterol.
  • The glucose in the blood
  • Muscle and bone density
  • The flow of blood and circulation
  • Your skin’s collagen and hydration levels
  • Cognitive abilities, such as attention.

Where may estrogen be found?

Throughout puberty and ovulation, your ovaries produce a flood of estrogen. The adrenal glands, which are located on top of each kidney, and adipose tissue (fat) also release estrogen. During pregnancy, estrogen is secreted by the placenta (the organ that enables the transfer of nutrients from mother to child).

As estrogen is secreted, it travels through the bloodstream until it reaches the target area, where it stimulates the desired physiological response. The process begins when estrogen connects to a specific protein called an estrogen receptor. Your entire body contains estrogen receptors.

Estrogen-related diseases and disorders, and how prevalent are they?

Estrogen is relevant to the majority of women’s health issues. Among the most typical are:

  • Low estrogen levels have been linked to conditions like anorexia nervosa. Lack of estrogen might lead to menstrual disruptions and absences (amenorrhea). Models, athletes, and others who have very low body fat percentages may also suffer from low estrogen levels.
  • Research has indicated that while prolonged exposure to estrogen does not raise the likelihood of developing breast cancer, it may make an existing case of the disease worse.
  • Although estrogen does not directly cause endometriosis, it may exacerbate the symptoms of those who already have it.
  • Feminine sexual dysfunction (FSD) occurs when low estrogen levels lead a woman’s body and mind to undergo changes that make sexual activity unpleasant. Yet, estrogen replacement therapy isn’t even explored until beyond menopause.
  • Breast discomfort associated with fibrocystic disease may be attributed to changes in estrogen levels that occur during the menstrual cycle.
  • Menstrual cycle disruption due to low or excessive estrogen levels contributes to infertility. It’s possible that the underlying reasons for low and high estrogen levels are linked to infertility.
  • Those who are overweight tend to have greater estrogen levels because of their excess fat.
  • Osteoporosis may be observed which is characterized by bone fragility and breakage as a result of low estrogen levels.
  • Polycystic ovarian syndrome (PCOS) is a hormonal disorder caused by an excess of androgen production by the ovaries (hormones associated with being assigned male at birth). When dealing with PCOS, it is not uncommon for estrogen levels to be excessive in comparison to progesterone levels.
  • Premature menopause is caused by a disorder called primary ovarian insufficiency, in which the ovaries stop producing eggs too early (before age 40). Because of this, your ovaries are unable to produce adequate amounts of estrogen for your body.
  • Hormonal fluctuations before menstruation can cause PMS and PMDD, two conditions characterized by uncomfortable physical and emotional symptoms. One possible cause of PMS and PMDD is a drop in estrogen levels after ovulation.
  • Turner syndrome is characterized by low estrogen levels due to the underdevelopment of the ovaries. So, it is possible that people with this condition will never make breast tissue or have periods.
  • Endometrial cancer, which happens when the lining of the uterus thickens, has been linked to high estrogen levels. Cancer cells may begin to multiply at some point.
  • Overproduction of estrogen has been linked to the growth of fibroids and polyps, which are benign tumors of the uterus.
  • Too little estrogen can lead to vaginal atrophy (atrophic vaginitis), in which the vaginal lining thins and dries up. Menopause and its aftermath are the most prevalent times for vaginal shrinkage to occur.

The effects of estrogen on diseases in different body systems are still being investigated. Certain endocrine abnormalities and gastrointestinal ailments, for instance, have been related to estrogen.

Possible symptoms include:

If estrogen levels are always high, what will happen?

Polyps, fibroids, polycystic ovary syndrome, endometriosis discomfort, ovarian tumors, etc., can all be caused by an excess of estrogen in the body. One possible explanation for your elevated levels is an estrogen-to-progesterone ratio that’s too high. You may have an excess of estrogen because of the medications you are taking.

Possible symptoms include:

  • lowered libido.
  • gaining a lot of weight around the middle and hips.
  • periodic fluctuations (unpredictable timing, light or heavy bleeding)
  • the aggravation of PMS or PMDD symptoms.

How can I be sure my estrogen levels stay normal?

Conditions caused by hormonal abnormalities are not always avoidable. Yet, there are measures you may take to improve your general health.

Ensure you’re getting enough shut-eye. Maintaining normal hormone levels in the body is dependent on getting a good night’s sleep every night.

Take care of yourself. The stress chemicals cortisol and adrenaline can be overproduced if you’re under a lot of pressure. High amounts of stress hormones have been linked to an imbalance in other hormones, specifically estrogen.

Do an appropriate quantity of physical activity. Getting in some regular exercise might aid in keeping your calorie and fat intake in check. Better sleep is another benefit.

If you drink alcohol, cut back. When you drink, your body produces more estrogen. The risk of developing cancer with prolonged exposure to estrogen is unknown.

Develop healthy eating routines. Keep an eye on what you eat to keep your hormones in check. Hormone balance can be achieved by consuming fewer sugary meals and more fiber- and healthy fat-rich foods like olive oil, nuts, seeds, and fish.

Good health women

Conclusion

Reproductive health and overall wellness depend on adequate estrogen levels. Estrogen levels fluctuate normally with aging and the monthly menstrual cycle. You should talk to your doctor about any bothersome symptoms you’re experiencing if they seem to be abnormally high or low. Helpful treatments are available, including contraception, changes to one’s lifestyle, and hormonal medicines for women who have gone through menopause.
