What Are Androgens? A Complete Guide to Your Body's Key Hormones

You have likely heard about hormones before. They act like tiny chemical messengers that control how your body works every single day. Today, we are taking a close look at a very important group of hormones called androgens. While the name might sound a bit new to you, these chemical messengers are vital for everyone's health. They play a major role in your sexual development and keep your reproductive system healthy and strong.

Think of androgens as the quiet workers behind the scenes in your body. They help manage your energy, support muscle growth, and guide your body through major life stages. Whether you are growing up during puberty or going through natural life changes later on, androgens are always working hard to keep your body balanced.

What Are Androgens and Where Are They Made?

Simply put, androgens are a category of sex hormones. They guide the physical changes that happen when you grow from a child into a teenager during puberty. They also keep your reproductive system working properly throughout your adult life.

Your androgen levels can shift throughout the day. They also change greatly during major life milestones, such as puberty or later in life during menopause. Everyone produces androgens, but male bodies naturally produce them in much higher amounts. The most common and powerful androgen is testosterone.

Different parts of the body produce these hormones:

• In male bodies, the testicles produce the largest amount of androgens.
• In female bodies, the ovaries produce smaller amounts of androgens.
• The adrenal glands, which sit just above your kidneys, also produce small amounts of androgens in everyone.

What Are the Main Types of Androgens?

As we mentioned, testosterone is the main leader of this hormone group. However, your body relies on several other important androgens as well. Many of these work as building blocks to create other vital hormones in your system.

• Androstenedione: A key hormone that helps your body create testosterone and estrogen.
• Dehydroepiandrosterone (DHEA): A hormone produced by the adrenal glands that helps create other sex hormones.
• DHEA Sulfate (DHEAS): A stable form of DHEA that circulates in your blood to support hormone production.

These three substances act as raw materials. Your body uses them to build testosterone and the female hormone estrogen. Another critical androgen is dihydrotestosterone (DHT). As you grow into an adult, your body naturally converts a small percentage of your daily testosterone into DHT.

Your body uses these hormones in a complex and harmonious way. Think of it like a skilled orchestra playing music together where every instrument has a vital part to play.

What Do Androgens Do for Your Body?

Androgens are much more than just simple sex hormones. They perform many essential jobs across your entire body, regardless of your gender.

• Bone Density: They help keep your bones strong and healthy as you age.
• Muscle Development: They support muscle growth and physical strength.
• Puberty: They trigger the physical changes that happen when you grow into a teenager.
• Red Blood Cell Production: They encourage your bone marrow to make red blood cells, which carry oxygen through your body.
• Sexual Desire: They play a key role in maintaining a healthy sex drive and function.

Now let's take a closer look at how androgens specifically affect male and female bodies.

Why Androgens Matter for Men.

When a young boy goes through puberty, androgens—especially testosterone—drive many of the physical changes you can easily see.

• Deep Voice: Your vocal cords lengthen, which causes your voice to change and deepen.
• Getting Taller: They speed up your overall growth so you reach your adult height.
• Hair Growth: Hair starts to grow on your face, scalp, chest, underarms, and genital areas.
• Sperm Development: They signal your body to start producing sperm, which is necessary for reproduction.

These changes start during your teen years. However, testosterone levels naturally begin to decline very slowly as you grow older.

Why Androgens Matter for Women.

Inside a female body, androgens like testosterone undergo a chemical conversion to create an estrogen hormone called estradiol. This hormone is vital for women's health.

• Secondary Sexual Characteristics: They help develop female traits during puberty, such as breast growth and widening hips.
• Regulates Menstruation: They help keep your monthly menstrual cycle regular and predictable.
• Aids Conception: They support fertility and help maintain a healthy pregnancy.
• Minimizes Bone Loss: They protect your bones from becoming fragile and reduce the risk of osteoporosis as you age.

Your estradiol levels also change during different stages of life. After menopause, the body stops producing large amounts of these hormones.

Health Issues Caused by Androgen Imbalances.

Like many things in life, balance is everything. When your androgen levels become too high or too low, it can lead to various health concerns.

Health Issues in Men.

For men, the most common concern is having low androgen levels, especially low testosterone. Doctors call this condition male hypogonadism.

• Low sex drive can make you lose interest in intimacy.
• Difficulty getting or keeping an erection can occur.

In certain medical situations, androgens can encourage the growth of prostate cancer. When this happens, doctors use special medicines to lower the body's androgen production. This treatment is called Androgen Deprivation Therapy (ADT).

also, male pattern baldness, known medically as androgenic alopecia, is closely linked to how your hair follicles react to DHT.

Health Issues in Women.

For women, health issues usually happen when androgen levels are too high. Doctors call this hyperandrogenism. The most common cause is a condition called Polycystic Ovary Syndrome (PCOS). Sometimes, rare growths on the adrenal glands or ovaries can also cause higher androgen levels.

If you have high androgen levels or PCOS, you might notice symptoms such as:

• Persistent acne on your face, chest, or back.
• Missed, irregular, or completely stopped periods, known as amenorrhea.
• Excess hair growth on your face, chest, or other areas, known as hirsutism.
• High blood pressure and high cholesterol levels.
• Difficulty getting pregnant, also known as infertility.
• Weight gain or trouble managing your weight, linked to obesity.

Just like in men, high levels of androgens can sometimes contribute to hair thinning or hair loss in women.

Health Issues in Children.

When children experience unusual shifts in their androgen levels, it can cause puberty to start either way too early, known as precocious puberty, or get delayed.

also, disorders of sexual development can involve androgen levels. This is not just one single condition. It refers to a group of about 60 different conditions where a child's physical traits do not fit typical male or female patterns.

How Do Doctors Measure Androgen Levels?

If your doctor suspects you have an issue with your hormone levels, they can use simple blood tests to find out what is going on.

For women, doctors often check a calculation called the Free Androgen Index (FAI). To calculate this, they draw a blood sample and measure a few key things:

• Total testosterone levels in your blood.
• Free testosterone that is active in your system.
• Sex-hormone-binding globulin (SHBG).

SHBG is a special protein that carries testosterone, DHT, and estrogen through your bloodstream. By comparing your total testosterone to your SHBG level, your doctor can see how much active hormone you actually have.

For men, doctors usually rely on a straightforward testosterone blood test to check if levels are lower than normal.
