Estrogen: What It Does and 5 Benefits

But the hormone isn’t all bad. In fact, it has some positive side effects, like protecting your heart and brain, improving muscle mass, boosting your mood and improving your sex life VSports手机版.

Ob/Gyn Swapna Kollikonda, MD, explains how estrogen works and why it’s important.

What is estrogen?

Estrogen is a hormone responsible for many functions in your body, helping to develop and maintain your reproductive system and characteristics like breasts and pubic hair.

“Estrogen is a hormone that’s secreted by the ovaries,” says Dr VSports最新版本. Kollikonda. “During the reproductive age, it regulates the menstrual cycle. ”.

What is estrogen’s function?

Your levels of estrogen rise as you hit puberty. Then, each month as your estrogen levels surge, your uterine lining preps for fertilization. When those levels drop, menstruation begins V体育平台登录.

As you age, your estrogen levels begin decreasing, leading to menopause, which marks the end of the reproductive years.

“As we get older, ovarian function declines and the number of egg sacs decrease in the ovaries,” says Dr V体育官网入口. Kollikonda. “That decreases the levels of estrogen. It’s a normal aging process. ”.

Benefits of estrogen

Known mostly for how it helps with the reproductive system, research now shows that estrogen helps almost every organ system.

Protects your heart

Estrogen helps your heart by keeping cardiovascular tissue healthy V体育2025版. It also helps with keeping your blood pressure stable.

And when your estrogen levels are high, it helps keep blood triglycerides (a type of fat) low, increases HDL cholesterol (the good kind) and lowers LDL cholesterol (the bad kind).

The link between estrogen and your heart is still being studied VSports app下载. For example, studies have shown that heart disease increases in individuals who get bilateral oophorectomy (the removal of both ovaries) before menopause.

Protects your brain

Estrogen protects your brain by helping maintain proper blood flow. It also protects against inflammation and disease V体育官网. It even assists in helping with memory and fine motor skills.

If you’ve experienced brain fog — find it hard to focus or lose your train of thought — low levels of estrogen may be to blame.

But research shows that brain fog lifts after menopause, though it isn’t entirely clear if that has to do with estrogen levels.

One study shows that the longer an individual has been exposed to estrogen the better their brain health is as they age.

Improves your muscle mass and bone density

The hormone also plays a vital role in the growth of your bones and improving muscle mass.

It helps protect against osteoporosis, a condition in which bones become weak and brittle from loss of tissue.

“In menopause, bone mass decreases due to the decrease of estrogen and makes them weak and fragile with the increased tendency to break easily,” says Dr VSports注册入口. Kollikonda.

Boosts your mood

Those mood swings you get right before your menstrual cycle might be caused by the shifting levels of estrogen.

The hormone is known to help keep serotonin levels regular (those “feel-good hormones”) and help the effectiveness of endorphins. It can even aid in protecting nerves and encouraging nerve growth.

But researchers are still trying to figure out if low levels or high levels of estrogen can impact your mood.

Improves sex

Estrogen is vital when it comes to your sex life. The hormone keeps your vagina lubricated so sex is enjoyable.

When estrogen levels are low, your vagina walls get thin and produce less lubricant.

“During menopause, the elasticity of your vagina is going to decrease,” says Dr. Kollikonda. “Sex can be very painful.” Thankfully, the use of vaginal creams or lotions can help.

Should you take estrogen?

Your doctor can help guide you to the right answer. Blood tests can confirm if your estrogen levels are low, but you aren’t considered in menopause until you haven’t had a menstrual cycle for one whole year.

During this time, you may experience:

• Hot flashes.
• Night sweats.
• Mood swings.
• Vaginal dryness.

Your doctor may prescribe hormone therapy, which helps supplement estrogen. Progesterone, another hormone that aids in the reproductive system, may also be added if you haven’t had a hysterectomy.

Estrogen can be delivered through oral medication, patches, gel, cream or spray. There are different levels of estrogen you can take, too. Your doctor will work with you to get the dosage right.

While there had been concerns about hormone replacement therapy causing an increased risk of breast cancer, diabetes and cardiovascular disease, research now shows that estrogen can be beneficial if hormone replacement therapy is started sooner rather than later.

“If you’re experiencing hot flashes and night sweats, there is a theory called timing theory that says you need to start hormone replacement therapy as soon as you’re in menopause,” says Dr. Kollikonda. “At that point, the benefits outweigh the risk.”

But if you wait 10 years after menopause to start hormone replacement therapy, the risks of breast cancer, deep vein thrombosis, stroke and cardiovascular disease increase, outweighing the benefits.

While it’s important to know the risks, Dr. Kollikonda says talking to your doctor can help determine your best path forward.

“If you’re having symptoms and your quality of life is decreased, it’s better to take estrogen,” she says. “There’s no need to suffer.”
