Male Hormones Blood Test

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Works with FSH to regulate reproductive function. In women, an LH surge triggers ovulation. In men, LH stimulates testosterone production. Abnormal levels can indicate pituitary or gonadal disorders.

The most potent and prevalent form of estrogen. In women, estradiol regulates the menstrual cycle, fertility, and bone density. In men, it's produced from testosterone and plays roles in bone health and libido. Levels vary significantly with age and menstrual cycle.

The primary male sex hormone, also important in women at lower levels. Testosterone regulates muscle mass, bone density, fat distribution, libido, and mood. Levels decline naturally with age in both sexes.

A hormone primarily known for stimulating breast milk production. Elevated prolactin in non-pregnant individuals can indicate pituitary tumors, medication side effects, or hypothyroidism. High levels can suppress reproductive hormones.

Regulates reproductive function in both sexes. In women, FSH stimulates egg development; elevated levels indicate declining ovarian reserve or menopause. In men, FSH stimulates sperm production.

A calculated ratio of total testosterone to SHBG that estimates the amount of biologically active testosterone. FAI is particularly useful in women for assessing androgen excess in conditions like PCOS.

Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.

A hormone produced by the adrenal glands, serving as a precursor to testosterone and estrogen. DHEA peaks in early adulthood and declines steadily with age. It's one of the most studied biomarkers in anti-aging research.

A protein that binds and transports sex hormones (testosterone, estrogen) in the blood. High SHBG reduces the amount of free, active hormones available. SHBG increases with age, thyroid hormones, and estrogen; decreases with obesity and insulin resistance.

The primary stress hormone, produced by the adrenal glands. Cortisol regulates metabolism, immune response, blood pressure, and the sleep-wake cycle. Chronically elevated cortisol from stress contributes to weight gain, immune suppression, and metabolic dysfunction.

The sulfated, stable form of DHEA with a long half-life, making it the preferred test for adrenal androgen production. DHEA-S is the most abundant circulating steroid hormone and a key longevity biomarker.

The unbound, biologically active fraction of testosterone (typically 1–3% of total). Free testosterone is the form that can enter cells and exert effects. More clinically relevant than total testosterone for assessing hormonal status.
