Calcitonin – Calcitonin is a protein hormone secreted by cells in the thyroid gland. It inhibits bone degradation and stimulates the uptake of calcium and phosphate by bone.
Cholesterol – Cholesterol is a white crystalline substance found in animal tissues and various foods that is normally synthesized by the liver. It is an important constituent of cell membranes and a precursor to steroid hormones.
Congenital Adrenal Hyperplasia – Congenital adrenal hyperplasia refers to a group of inherited adrenal gland disorders. People with this condition do not produce enough of the hormones cortisol and aldosterone, and produce too much of androgen.
Cortisol – Cortisol is a hormone produced by the adrenal gland. It is involved in the stress response and increases blood pressure and blood sugar levels.
Cushing's syndrome – Cushing's syndrome is a hormonal disorder caused by prolonged exposure of the body's tissues to high levels of the hormone cortisol. Sometimes called "hypercortisolism," it is relatively rare and most commonly affects adults aged 20 to 50.
Diabetes – Diabetes is a disease in which blood glucose levels are above normal. The body of a person with diabetes either doesn't make enough insulin or can't use its own insulin as well as it should.
Dihydrotestosterone – Dihydrotestosterone is a male hormone more potent than testosterone that is converted from testosterone within the prostate.
Endocrine Disruptor – Endocrine disruptors are natural and man-made chemicals that can either mimic or disrupt the action of hormones. Their impact on human biology is still unclear, but they have been implicated in a number of reproductive and health problems in animals.
Endocrinologist – An endocrinologist is a doctor that studies the glands and hormones of the body and their related disorders.
Erectile Dysfunction (ED) – Erectile dysfunction is a condition referring to the inability to achieve penile erection or to maintain an erection until ejaculation.
Estradiol – Estradiol, a type of estrogen, is a female sex hormone produced mainly by the ovaries. It is responsible for growth of breast tissue, maturation of long bones, and development of the secondary sexual characteristics.
Estrogen – Estrogens are a group of steroid compounds that are the primary female sex hormones. They promote the development of female secondary sex characteristics and control aspects of regulating the menstrual cycle.
Estrogen Therapy (ET) – Estrogen therapy is a hormone therapy treatment program in which women take estrogen orally, transdermally, or vaginally to treat certain symptoms of menopause.
Free Testosterone – Free testosterone is testosterone in the body that is biologically active and unbound to other molecules in the body, such as sex hormone binding globulin.
Follicle stimulating hormone (FSH) – In women, FSH helps control the menstrual cycle and the production of eggs by the ovaries. The amount of FSH varies throughout a woman's menstrual cycle and is highest just before she ovulates. In men, FSH helps control the production of sperm.
