Androgens & Your Cycle: The Hidden Driver

When most people think about female hormones, they think about estrogen and progesterone. These two get the headlines, the cycle-tracking apps, and the lion's share of the research. But there is a third group of hormones quietly shaping everything from your drive and confidence to your skin texture and libido: androgens. And the way your body responds to them changes across every phase of your cycle in ways that most women have never been told about.

Androgens are often labelled as "male hormones," but women produce them too, primarily in the ovaries and adrenal glands. Testosterone, DHEA (dehydroepiandrosterone), androstenedione, and DHT (dihydrotestosterone) are all part of this hormonal family. Understanding how they rise, fall, and interact with your other hormones across your cycle is one of the most underrated tools for working with your body rather than against it.

What Are Androgens and Why Do Women Need Them?

Androgens are steroid hormones made from cholesterol. In women, they serve a long list of functions that have nothing to do with "masculinity." They are essential precursors to estrogen, meaning the body actually converts androgens into estradiol using an enzyme called aromatase. Without sufficient androgens, estrogen production suffers too.

Beyond that, androgens contribute to:

• Libido and sexual arousal
• Muscle growth and physical strength
• Bone density
• Mood stability and motivation
• Cognitive function and focus
• Energy levels and stamina
• Red blood cell production

According to research from the National Institute of Child Health and Human Development, androgen excess is the most common hormonal disorder in women of reproductive age, affecting up to 10% of the female population. But androgen deficiency is equally important and far less discussed.

"Androgens are not just male hormones. They are fundamental to female physiology, influencing everything from bone health to sexual function to mood. Women need to understand their androgen levels just as much as their estrogen levels." - Dr. Susan Davis, MBBS, PhD, Professor of Women's Health, Monash University

How Androgens Fluctuate Across Your Cycle

Androgens do not stay constant throughout your menstrual cycle. They have their own rhythmic pattern that interacts with and influences the estrogen and progesterone fluctuations you may already be tracking.

Menstrual Phase (Days 1-5 approximately)

During menstruation, estrogen and progesterone are at their lowest. Androgen levels, particularly testosterone, are also relatively low, which can contribute to the fatigue and low motivation many women experience at this time. DHEA, which acts as a buffer for the stress response, tends to be at a weekly low point as well. This is a time when the body genuinely benefits from rest and lower-intensity demands.

Follicular Phase (Days 6-13 approximately)

As follicle-stimulating hormone (FSH) rises and follicles begin to mature, androgen production starts to ramp up. The ovaries produce more testosterone and androstenedione in preparation for ovulation. You may notice this as a gradual return of drive, focus, and a subtle increase in confidence. Skin may also start to feel more balanced as sebum production remains relatively stable.

Ovulatory Phase (Days 14-16 approximately)

Here is where androgen levels peak. A study published through the National Institutes of Health confirmed that testosterone levels in women show a statistically significant mid-cycle surge that coincides with the luteinizing hormone (LH) surge and ovulation. This testosterone peak is not incidental. It is biological design. It drives libido, assertiveness, physical performance, and the kind of magnetic social energy that many women notice but cannot always explain.

This is also why ovulation is often described as a window of peak confidence and communication. The androgen surge works synergistically with the estrogen peak to create an environment where women often feel most like themselves.

Luteal Phase (Days 17-28 approximately)

After ovulation, progesterone rises sharply and becomes the dominant hormone. Androgens begin to decline, though they do not disappear entirely. The fall in testosterone can contribute to the shift in mood and motivation many women experience in the second half of their cycle. However, there is an important nuance: in the late luteal phase, when progesterone drops sharply before menstruation, androgens can become relatively more prominent by comparison. This relative androgen exposure, combined with low progesterone, is thought to be one factor behind premenstrual breakouts, increased oiliness, and the low mood associated with PMS.

Androgen Sensitivity: The Factor Nobody Talks About

Here is where it gets more personal. Two women can have the same measurable testosterone level and experience completely different effects. The key variable is androgen receptor sensitivity, which is largely determined by genetics.

Androgen receptors are proteins found in cells throughout the body, including the skin, brain, muscles, and ovaries. When androgens bind to these receptors, they trigger a biological response. But if your receptors are more sensitive, a small amount of androgen produces a larger response. If your receptors are less sensitive, you may need higher circulating levels to notice any effect at all.

This explains why some women experience significant acne with "normal" testosterone levels while others with elevated testosterone have clear skin. It also explains variability in libido, body hair, and how strongly a woman feels the ovulatory energy peak.

"Androgen receptor polymorphisms explain a significant portion of the variation we see in how women experience their cycles. It is not just about how much testosterone is circulating but how receptive the tissues are to that signal." - Dr. Jerilynn Prior, MD, Professor of Endocrinology, University of British Columbia

Signs Your Androgens May Be Too High

Androgen excess, also called hyperandrogenism, is the hormonal backdrop of PCOS, but it can also occur without a PCOS diagnosis. Common signs include:

• Persistent acne, particularly along the jawline and chin
• Increased facial or body hair (hirsutism)
• Scalp hair thinning or loss at the temples or crown
• Irregular or absent periods
• Oily skin that worsens before your period
• Mood changes including irritability and agitation
• Difficulty losing weight, particularly around the abdomen

It is worth noting that insulin resistance amplifies androgen production. The Office on Women's Health notes that insulin stimulates the ovaries to produce more androgens, which is one reason why blood sugar stability is so central to managing conditions like PCOS.

Signs Your Androgens May Be Too Low

Androgen deficiency in women is underdiagnosed, partly because reference ranges are still debated and partly because symptoms overlap with many other conditions. Signs to watch for include:

• Persistent low libido even when estrogen is adequate
• Chronic fatigue that does not resolve with rest
• Loss of motivation or initiative
• Reduced muscle tone despite regular exercise
• Flat or blunted mood, low enthusiasm
• Reduced sense of wellbeing
• Brain fog and difficulty concentrating

Low androgens are particularly common after surgical menopause (following removal of the ovaries), during perimenopause, and in women who have been on combined oral contraceptives for extended periods. The pill raises sex hormone-binding globulin (SHBG), a protein that binds to free testosterone and makes it unavailable to tissues, effectively lowering androgenic activity even when total testosterone remains measurable.

What Influences Your Androgen Levels Day to Day?

Androgens are sensitive to lifestyle factors in ways that give you genuine leverage. Here is what the research shows:

Stress and the HPA Axis

Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis and shifts adrenal output toward cortisol, often at the expense of DHEA. DHEA is sometimes called the "anti-aging" or "anti-stress" androgen because it counterbalances cortisol's effects. When stress is chronic, DHEA production drops and with it, the buffering effect on the nervous system that makes you feel resilient. Managing stress is not just good for progesterone (the commonly cited victim of the "cortisol steal"). It matters for your androgens too.

Sleep Quality

Testosterone production follows a circadian pattern, peaking during sleep and in the early morning hours. Poor or disrupted sleep measurably reduces androgen output. If you wake unrefreshed and notice low motivation or flat mood, your androgen rhythm may be disrupted by sleep debt.

Exercise Type and Timing

Resistance training is one of the most consistent androgen-supporting lifestyle choices. Short, intense strength sessions temporarily raise testosterone in women, while chronic overtraining can suppress adrenal androgens and worsen fatigue. Aligning your harder training sessions with your follicular and ovulatory phases, when androgens are naturally rising, may enhance your response and recovery.

Body Fat and Adipose Tissue

Fat cells contain aromatase and convert androgens to estrogen. Higher body fat levels can lower available androgens while simultaneously elevating estrogen. This is one pathway through which excess weight contributes to estrogen dominance, and it is a bidirectional relationship: androgen changes can also influence where and how the body stores fat.

Dietary Protein and Zinc

Adequate dietary protein supports testosterone production. Zinc is essential for the enzyme systems involved in androgen synthesis and is depleted by menstruation, making it particularly important to replenish after your period. Foods rich in zinc include oysters, pumpkin seeds, beef, and legumes.

Cycle Syncing With Your Androgen Rhythm

Once you understand how androgens move across your cycle, you can begin to align your energy demands accordingly rather than forcing the same output every day.

• Menstrual phase: Respect the low. Prioritise rest, nourishment, and reduced decision-making load. Your androgen trough is real.
• Follicular phase: Begin to increase training intensity, take on new projects, and engage with tasks requiring focus as your androgens rise.
• Ovulatory phase: Lean into the peak. High-stakes conversations, public presentations, peak athletic performance, and social connection all benefit from this androgen and estrogen surge.
• Luteal phase: Shift to maintenance. Moderate exercise, detail-oriented work, and consolidation of ideas all suit the declining androgen environment. Watch for the relative androgen excess in the late luteal phase that may amplify skin sensitivity and irritability.
