Fatigue. Poor sleep. Mood changes. Decreased sex drive. Difficulty maintaining muscle. Irregular menstrual cycles.
Sometimes hormones are part of the problem. Other times, they are one piece of a larger picture.
That distinction matters because good care must identify which situation is present before treatment is thoughtfully planned.
Good hormone care should not begin with a prescription. It should begin by understanding the person, the symptoms, the timing and quality of testing, and the physiology behind the numbers.
HORMONES DON’T WORK IN ISOLATION
The endocrine system is interconnected. Testosterone, estrogen, progesterone, thyroid hormones, cortisol, and insulin do not operate independently. Sleep, nutrition, exercise, medications, illness, metabolic health, and stress can influence symptoms and hormone production.
That is why fatigue or decreased libido should not automatically be labeled a “hormone imbalance.” But the opposite is also true: a laboratory result marked “normal” does not answer every clinical question.
Reference ranges are useful, but they require context. Age, sex, menstrual status, medications, symptoms, health history, and collection conditions affect interpretation. The goal is not to chase an arbitrary “optimal” number, but to understand what the result means for the individual.
MALE HORMONES: TESTOSTERONE IS MORE THAN A NUMBER
Testosterone supports male sexual function, muscle and bone health, and red blood cell production. Deficiency may cause decreased libido, erectile dysfunction, reduced energy, or loss of muscle mass. Symptoms alone, however, do not establish the diagnosis.
The Endocrine Society recommends diagnosing hypogonadism only when compatible symptoms or signs occur with consistently low testosterone. A low result should generally be confirmed with a repeat morning fasting measurement. Testosterone fluctuates, illness can temporarily lower it, and laboratory methods differ.
LH and FSH can help distinguish a testicular problem from a hypothalamic or pituitary cause. Obesity, sleep disorders, medications, illness, and nutrition may also affect testosterone. Raising the number without investigating the cause can miss the real problem.
Goals matter too. Testosterone therapy can suppress sperm production, so fertility should be discussed first. When replacement is appropriate, follow-up should assess symptoms, testosterone, hematocrit, adverse effects, and patient-specific risks. The objective is appropriate treatment, monitored responsibly.
FEMALE HORMONES: TIMING CHANGES EVERYTHING
Female hormone evaluation is challenging because concentrations naturally change throughout the menstrual cycle. Progesterone is a clear example.
Progesterone rises after ovulation and usually peaks about six to eight days later, yet it is secreted in pulses and can fluctuate substantially over a short period. Therefore, timing is essential.
The familiar “day 21 progesterone” is not appropriate for every woman. Testing is better timed about one week before the anticipated next period, based on the individual cycle. A progesterone level above 3 ng/mL provides presumptive evidence of recent ovulation, but one value cannot define overall luteal function.
ESTROGEN, PROGESTERONE, AND MENOPAUSE
Estrogen helps build the uterine lining during the first portion of the menstrual cycle. After ovulation, progesterone from the corpus luteum helps prepare that lining for a potential pregnancy. When ovulation is irregular, progesterone exposure may also be irregular, contributing to unpredictable bleeding.
The picture changes again during perimenopause. Hormone production can vary considerably as menopause approaches. Cycles may shorten, lengthen, become heavier or lighter, or occasionally disappear. Hot flashes, sleep disruption, vaginal dryness, and changes in sexual function may occur. A single estrogen or progesterone measurement may therefore provide only a snapshot.
For appropriate patients with menopausal symptoms, hormone therapy can be effective. ACOG identifies systemic estrogen as the most effective treatment for hot flashes and night sweats, and it may improve vaginal symptoms. For a woman with a uterus who uses systemic estrogen, a progestogen is generally required to reduce the risk of endometrial cancer from unopposed estrogen.
Hormone therapy is not universal. Symptoms, age, history, time since menopause, reproductive goals, contraindications, and individual risks must guide the decision.
LIBIDO IS MORE COMPLICATED THAN ONE HORMONE
Sex drive is a common reason people request hormone testing—and one of the easiest symptoms to oversimplify.
Testosterone and estrogen may contribute, but libido is also influenced by sleep, stress, medications, metabolic health, depression or anxiety, vaginal discomfort, erectile function, relationship factors, and overall physical health. Around menopause, vaginal dryness or painful intercourse can understandably reduce desire. In men, low testosterone may contribute to decreased libido, but therapy is not appropriate solely because someone wants a higher sex drive; deficiency should first be established.
Sexual health is hormonal, physical, psychological, and relational. Good care considers every part.
WHEN “NORMAL” DOESN’T END THE CONVERSATION
Laboratory values are essential tools, but they are not diagnoses by themselves. A person may feel exhausted despite normal hormone results. Another may have an abnormal value and feel completely well.
The better questions are: What changed? Was the test obtained correctly? Does the finding fit the symptoms? Could sleep, medications, anemia, mood, metabolic disease, or another condition explain it? Is treatment likely to improve health?
THE BIGGER PICTURE
Hormonal health overlaps with cardiometabolic health. Sleep quality, resistance training, nutrition, body composition, insulin resistance, cardiovascular health, and medications all influence how people feel.
Sometimes hormone therapy is the appropriate next step. Sometimes it is improving sleep, treating another condition, strengthening nutrition, changing training, addressing metabolic health, ordering additional testing, or simply providing reassurance.
THE PULSE APPROACH
At Pulse Cardiometabolic Wellness, hormone evaluation is part of a broader conversation—not a reaction to one laboratory number.
Sleep. Nutrition. Exercise. Body composition. Cardiovascular and metabolic health. Medications. Stress. Sexual health. Symptoms. Laboratory findings.
They all matter.
My approach is straightforward: test appropriately, understand the physiology, treat when indicated, and always monitor the response.
Hormones may be an important piece of the puzzle, but they should not become the entire puzzle. The goal is not perfect numbers on a report. It is to understand what your body is telling you and make informed decisions about your health.
