Luteinising Hormone (LH) is produced and released in the anterior pituitary gland and is an important part of a woman’s menstrual cycle.
Oestradiol is a steroid hormone and the strongest of the three naturally-produced oestrogens. It has many functions but primarily acts to mature and maintain the female reproductive system.
Follicle-stimulating hormone (FSH) is synthesised and secreted by the anterior pituitary gland and regulates the development, growth maturation and reproductive processes of the body..
The thyroid is a butterfly shaped gland found in the throat, wrapped around the windpipe just below the Adam’s apple. It produces thyroid hormones which influence essentially every organ, every tissue and every cell in the body. Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland and stimulates the thyroid gland to produce thyroid hormones thyroxine (T4) and triiodothyronine (T3). TSH that is too high or too low indicates that your thyroid gland is not functioning correctly.
“Free” thyroxine (T4) is not bonded to a protein in the blood. Free thyroxine is available for the body to use.
