Most of the time it is related exclusively to female hormones, estrogen produced by the ovaries helps prevent bone loss , circulates in the bloodstream and binds to estrogen receptors on cells which influences particular tissues that brings about changes not only in breasts and uterus but also the liver, bone ,heart and brain. It plays a crucial role in the development of female secondary sex characteristics, such as breasts, wider hips, pubic hair and armpit hair.  However, the role estrogen in men is not entirely clear. Disturbance of estrogen levels during menopausal stage of woman can cause physical and emotional changes called perimenopause. The fluctuations in the estrogen levels during this period results in range of symptoms such as irregular menstrual cycles, tenderness in breast, mood swings, mental illnesses (anxiety, depression, stress), migraines and most importantly hot flashes.
  • Testosterone – testosterone is a male hormone, which is produced by testes which plays an important role in the development of reproductive tissues and development of male secondary sexual characteristics (increased muscle and bone mass, facial hair).Testosterone plays a vital role in maintaining men’s health, even women have testosterone hormone but in limited levels than men.
  • Thyroid hormones – thyroid gland is an essential gland which is under the control of pituitary gland (a small gland located at the base of the brain). Pituitary gland stimulates thyroid glands to produce thyroid stimulating hormones (TSH) thyroxin (T4) and triiodothyronoine (T3) that control the metabolism (conversion of oxygen and calories to energy), growth and development, temperature of the body and the use of energy by the body. Thyroid hormone is very important and plays a major role in brain development during infancy and childhood. The major role of thyroid glands is to collect iodine from the diet we consume and convert it into thyroid hormones. Thyroid cells are very important for the body to function properly because they are the only cells which has the ability to absorb iodine and combine it with compounds like amino acids and make the hormones T3 and T4.
  • Growth hormone (GH) – is a growth stimulating hormone in all living beings. It is made of 191 amino acids; single chain polypeptide growth hormone is secreted by anterior lobe of pituitary gland. Growth hormone is a small protein hormone released by pituitary gland, into the blood that travels and triggers the liver to produce insulin like growth factor (IGF), that promotes growth in children by multiplying long bones, and increase the length of the bones, thereby increasing the height of the child. Apart from increasing height in children and adolescents, growth hormone brings about many changes in the body.

  • Insulin- insulin is a hormone produced by pancreas that controls the glucose in the blood. It allows cells to use glucose to produce energy. Some cells can take glucose from the blood without insulin, but most cells do require insulin to be present. The role of the insulin is to maintain the release of glucose from the liver. Glucose levels in the blood rise, after we eat food and trigger the pancreas to make insulin and release into blood. Without the production of insulin glucose cannot reach the cells and it remains in the blood stream.
