Can a man have high estrogen

Traditionally, testosterone and estrogen have been considered to be male and female sex hormones, respectively. However, estradiol, the predominant form of estrogen, also plays a critical role in male sexual function. Estradiol in men is essential for modulating libido, erectile function, and spermatogenesis. Estrogen receptors, as well as aromatase, the enzyme that converts testosterone to estrogen, are abundant in brain, penis, and testis, organs important for sexual function. In the brain, estradiol synthesis is increased in areas related to sexual arousal. In addition, in the penis, estrogen receptors are found throughout the corpus cavernosum with high concentration around neurovascular bundles.

Men with high estrogen levels could be at greater risk of breast cancer

Androgens are essential for male physical activity and normal erectile function. Moreover, estrogens also influence erectile function, and high estrogen levels are a risk factor for erectile dysfunction ED. In this review, we summarize relevant research examining the effects of the sex hormone milieu on erectile function.

Testosterone affects several organs, particularly erectile tissue. The mechanisms through which testosterone deficiency affects erectile function and the results of testosterone replacement therapy have been extensively studied. Estrogen, the female sexual hormone, also affects erectile function, as demonstrated in both clinical and basic studies. Interestingly, estradiol-testosterone imbalance is considered a risk factor for ED. Furthermore, endocrine-disrupting chemicals have estrogen-like effects and cause ED.

Phosphodiesterase-5 PDE-5 inhibitors, first-line drugs for the treatment of ED, increase the levels of testosterone and estradiol in patients with low testosterone levels. Therefore, estrogen levels should be carefully monitored in patients receiving PDE-5 inhibitors. Future studies are needed to confirm these findings using molecular tools in order to provide insights into the treatment and mechanisms of endocrine-related ED. Serum estrogen levels are correlated with symptoms of aging in men, and estrogen may therefore play an important role in aging [ 1 , 2 ].

Several previous studies have suggested that estrogen levels may also affect erectile function [ 3 , 4 , 5 , 6 ]. Indeed, older and obese men have been found to have not only low androgen levels but also high estrogen levels. Since testosterone is metabolized to estradiol by aromatase, the particularly high aromatase levels in visceral adipose tissue may explain the elevated estradiol levels among obese men [ 7 ]. Visceral adipose tissue often accumulates among men with increasing age.

Interestingly, high estrogen levels have been observed in older patients who present with a lack of sexual interest and erectile dysfunction ED ; therefore, these symptoms in the elderly are thought to involve a pathophysiological estrogen-testosterone imbalance [ 6 , 8 , 9 , 10 ]. Accordingly, in this review, we discuss the effects of sex hormone imbalances on male erectile function.

There are many reports on erectile function and sexual hormones. Erectile function is controlled by complex mechanisms [ 11 ], including the vascular and nervous systems [ 12 , 13 , 14 , 15 , 16 ]. One of the most important materials is a nitric oxide NO. After NO is releasing in the penis, corporal smooth muscle relaxes. However, when NO production is decreased, the erectile function weakened, resulting in ED. The relaxant system is also important for the erectile function.

The relaxant system is controlled by both the endothelial and the nervous systems. When the upper stream of smooth muscle relaxant system is weakened, ED is caused; therefore, many studies have focused on smooth muscle relaxation. In contrast, corporal smooth muscle contraction is controlled by constrictors, such as noradrenaline in the flaccid state. However, if the contraction be upregulated in some situations, ED would be caused.

Interestingly, some studies have indicated that smooth muscle relaxation and contraction balance is disturbed by abnormal activation of contractile signaling pathway such as the adrenergic regulation. In some syndromes causing ED, such as diabetes mellitus or metabolic syndrome, the contraction is enhanced [ 17 , 18 , 19 ]. The enhancement is known to occur in aged individuals.

Interestingly, the contractility of smooth muscle in the corpus cavernosum is regulated by sexual hormones and may play a significant role in erectile function. Testosterone deficiency and ED have been studied extensively [ 22 , 23 , 24 , 25 ]. Testosterone deficiency causes ED using castrated animal models [ 26 ].

In some studies, testosterone administration to the castrated animals improved NOS expression in the penis and restored the erectile function [ 27 ].

Testosterone also alters phosphodiesterase type 5 PDE-5 expression in the penis. These results indicate that testosterone is important for regulating PDE-5 expression.

Testosterone also affects the smooth muscle of the corpus cavernosum. Moreover, testosterone modulates the adrenergic response of the corpus cavernosum vascular smooth muscle [ 33 ]. These results indicate that when testosterone levels decrease, smooth muscle contractility also decreases. Their results indicated that testosterone deficiency increased smooth muscle contractility, leading to the decreasing erectile function and hypertension.

Thus, although testosterone deficiency may increase contraction, additional research is required to more fully elucidate its impact on smooth muscle contraction.

Interestingly, testosterone also directly affects smooth muscle relaxation. These findings indicate that testosterone may regulate erectile function locally by acting on corpus cavernosum smooth muscle. These results indicate that testosterone may affect both genomic and nongenomic mechanisms of erectile function. Testosterone also affects the structure of the penis. For example, castrated rats exhibit smooth muscle loss and fibrosis [ 37 ], and testosterone deficiency increases the volume of collagen in the internal pudendal arteries [ 38 ].

These effects of testosterone indicate that testosterone deficiency causes programmed trabecular smooth muscle cell death apoptosis [ 29 ]. Although their report had several limitations, they discussed the important role of testosterone in regulating the structural integrity of the corpus cavernosum and erectile function.

This resulted from testosterone regulating the counterregulation of autophagy and apoptosis by modulating the interactions between BECN1 and Bcl-2 key dual regulators of autophagy and apoptosis [ 41 , 42 ].

Estrogen, the female sex hormone, also affects erectile function. They show that testosterone has a negative association with the degree of atherosclerotic disease in the lower extremities [ 43 ]. On the other hand, estrogen also has association with ABI negatively in the males, leading to higher estradiol levels associated with increased atherosclerosis.

Moreover, both low testosterone levels and elevated estradiol levels affect erectile function and are associated with increased ED severity when present individually or concomitantly [ 44 ].

Low testosterone levels were thought to be the main effector; however, the presence of concomitantly elevated estradiol levels increased the severity of ED in patients with low testosterone levels. These reports indicated that female sex hormones also affect male health. Srilatha and Adaikan demonstrated that estradiol-testosterone imbalance is a risk factor for ED [ 8 , 45 , 46 ]. They showed that higher levels of estradiol were present in older patients experiencing with lack of sexual interest and ED, after adjustment for age [ 8 ].

Additionally, they concluded that the estradiol-testosterone hormonal balance may be a determinant of successful management outcomes for ED. These reports specifically demonstrated the relationship between high estrogen milieu and male erectile function.

Serum estrogen levels are controlled by aromatase but can be altered under some conditions. Moreover, they found that total estradiol levels may be increased based on sex hormone-binding globulin SHBG levels. Drugs such as phenytoin are known to cause elevations in serum estradiol and SHBG [ 50 ].

All these side effects have been reported in association with antiretroviral therapy as well. SHBG, similar to other globulins, is upregulated in patients with acquired immunodeficiency syndrome and human immunodeficiency virus infection [ 57 , 58 ].

They showed that overhydration in hemodialysis patients was associated with a higher prevalence of sexual dysfunction and depression, lower serum levels of total testosterone and dehydroepiandrosterone, and higher levels of serum estradiol.

They also reported that elderly men with low serum testosterone and estradiol have increased risk of mortality and that patients with low testosterone and estradiol levels have the highest risk of mortality [ 61 ]. Serum estrogen levels can be altered by some drugs and sex hormones.

Therefore, ED induced by high estrogen may be related to mortality. Interestingly, estrogen administration decreases erectile function in animal models [ 62 , 63 ]. Researchers administered estradiol orally to rats, resulting in high estradiol levels and low testosterone levels.

Moreover, the intracavernous pressure ICP response to nerve stimulation was also impaired in all treated groups, and trichrome staining demonstrated the presence of cavernosal connective tissue hyperplasia in long-term study groups [ 62 ]. Oral administration of estradiol to rabbits resulted in high estradiol levels and low testosterone levels, similar to the effects in rats.

Additionally, acetylcholine induced endothelium-mediated relaxation in normal animals, but this effect was significantly attenuated in treated groups, and NO-mediated nonadrenergic, noncholinergic neurotransmission was decreased in the treatment groups [ 63 ].

In our previous studies, subcutaneous administration s. Moreover, we administered testosterone to rats with high estrogen-induced testosterone deficiency; however, erectile function did not improve. We also investigated the influence of estradiol-testosterone imbalance on erectile function in rats Figures 1 — 6 ; Table 1. Table 1 shows the sex hormone concentrations in rats. Goserelin injection significantly decreased serum bioavailable testosterone control: 1.

B Histological evaluation of the tissues.

The area ratios of the collagen fibers, smooth muscle SM , and others were calculated using computerized image analysis. Figure 2 shows the erectile response to electrical field stimulation of the cavernous nerve in the different experimental groups. These data suggested that erectile responses were decreased in rats with a sex hormone imbalance. Figure 3 shows the contractile response of rat corpora cavernosa strips to increasing concentrations of noradrenaline NA.

Increasing concentrations of NA were found to contract rat corpora cavernosa strips in all groups. Figures 4 and 5 show the relaxant response of NA-precontracted rat corpora cavernosa strips to increasing concentrations of sodium nitroprusside SNP and Y The area ratio of the cavernous smooth muscle was analyzed control: Similarly, the area ratio of the collagen fiber was analyzed control: Several reports have suggested an association between ERs and ED.

These reports indicate that the ER exists in the corpus cavernosum and has various functions.

What Does High Estrogen In Men Mean?

Androgens are essential for male physical activity and normal erectile function. Moreover, estrogens also influence erectile function, and high estrogen levels are a risk factor for erectile dysfunction ED. In this review, we summarize relevant research examining the effects of the sex hormone milieu on erectile function.

Men are often unaware that estrogen estradiol plays a critical role in their day-to-day health. Estrogen is found in small-but-critical concentrations in men. It needs to be in balance with the rest of your hormones, especially testosterone, for you to feel well.

The impact of estrogen , however, is often overlooked, potentially leading you to struggle with disruptive symptoms without understanding their source. Both testosterone and estrogen have widespread influence on tissues and processes throughout the human body. Only through understanding the broad reach and profound influence of these powerful chemicals can you appreciate the danger that may be underlying high estrogen symptoms in men. Testosterone affects your sexual development, physique, and even your personality.

Testosterone and the Symptoms of High Estrogen in Men

Men with naturally high levels of the female hormone estrogen may have a greater risk of developing breast cancer, according to research by an international collaboration including Cancer Research UK published in the Journal of Clinical Oncology. This is the first time a link between estrogen levels in the blood and male breast cancer has been identified, despite its connection to breast, womb and ovarian cancers in women. Men with the highest levels of estrogen were two and a half times more likely to develop breast cancer than men with the lowest levels of the hormone. Male breast cancer is very rare with one man in every , diagnosed with breast cancer each year in the UK. Around male cases are diagnosed each year in the UK compared with nearly 50, cases of breast cancer in women. The aim was to study a large international pool of men with breast cancer. The research compared estrogen levels in men who went on to develop breast cancer with healthy men. Mark Cross, 46, a police officer from Cambridgeshire, was diagnosed with breast cancer in

The role of estradiol in male reproductive function

It is normal for both men and women to have a particular balance of testosterone and estrogen. Like a seesaw, when estrogen goes up, testosterone tends to drop. Women have more estrogen than men do and less testosterone on average. The most common high estrogen symptoms in men include sexual dysfunction of various kinds, from low desire to fewer erections.

Breast cancer in men is rare, but it does happen.

You can receive testosterone replacement therapy via telemedicine and prescriptions shipped to your door. Because he has to. High estrogen in men is a legitimate health concern.

High Estrogen Symptoms

You can receive testosterone replacement therapy via telemedicine and prescriptions shipped to your door. In reality, though, both men and women need estrogen to function properly. However, sometimes, male estrogen levels can get out of balance and cause a lot of problems in the body. Read on to learn everything you need to know about high estrogen in men and the risks that come with this condition.

Estrogen, majorly recognized as a female hormone chemical messengers. It is responsible for maintaining optimal health of women. But they are also found in males and is produced by the adrenal glands and testis. This hormone is important for proper male reproductive functions. A slight increase in its levels can result in a wide range of unwanted symptoms from weight gain to mood swings. Too little estrogen can predispose men to diseases like osteoporosis and also result in bone fracture in them.

The Health Risks Of High Estrogen In Men

While estrogen has traditionally been known as a female hormone and testosterone has traditionally been associated with men, it may surprise you to know that estrogen plays an integral role in male sexual function, including the regulation of sex drive, the development of sperm and even erectile function. But too much of any circulating hormone in the body isn't a good thing, typcially symptoms of high estrogen in men can include:. If you're worried about your own hormone health or perhaps someone you know, we have a range of tests that help identify male hormone issues. LetsGetChecked is joined by urologist Dr. Gregory Bernstein who offers insight into estrogen from the male perspective, as we discuss everything you need to know about high estrogen in men. What are the symptoms of high estrogen in men?

May 15, - About 2% of all breast cancer diagnosed in the United States is in men. While the link between estrogen and breast and ovarian cancer in women.

But while the benefits of testosterone replacement therapy are numerous, side effects are still a matter of course with any drugs or medical treatment. Although, when done properly the side effects of testosterone optimisation therapy are minimal. Nevertheless, in spite of this there is still one potential side effect that scares men more than any other:. Estrogen, particularly in the form of estradiol, affects libido, erectile function, and the development of the sperm within the male reproductive organs.

Recognizing High Estrogen Symptoms in Men and Regaining Balance

While its importance is normally attributed to women, estrogen in men plays an important role. As teenagers, men have high levels of testosterone and low levels of estrogen. As they age, testosterone levels in men decrease while their estrogen levels increase. Not surprisingly, high levels of estrogen in men usually correspond to low levels of testosterone.
