the pituitary gland
The pituitary gland is a small gland located in the cavity of the skull and controls all the glands in the body, because it secrete a large group of hormones that affect the secretions of these glands directly, so any defect in the pituitary gland will affect the functions of other glands, and the pituitary gland consists of three The frontal lobe, the posterior lobe, and the midriff. The front and middle lobe separate the hormone responsible for the adrenal glands, the milk hormone, the growth hormone, the thyroid hormone, the hormones responsible for the gonads, and the posterior lobe of the gland stores the pyramid Which produce and regulate secretion of the hypothalamus, such as oxytocin and anti-diuretic hormone, and hypothalamus regulates the action of the pituitary gland.
Hormones produced by the pituitary gland
- Hormones responsible for the gonads: These hormones responsible for regulating the secretion of gonadal hormone such as estrogen in females and testosterone in males, and these hormones are secreted from the anterior lobe of the pituitary gland.
- Hormone (LH): The pituitary gland secretes this hormone to stimulate the ovary on the production of eggs and the secretion of reproductive hormones, and in males this testicular stimulates the production of sperm.
- FSH: This hormone is responsible for the secretion of estrogen in females, which is important in the early stages of sperm formation, and the examination of the level of this hormone is important tests because it helps to know the causes of non-fertilization in men and women, and helps In the detection of the causes of irregular menstrual cycle, and in the detection of functions of the pituitary gland, and changes the level of hormone (FSH) according to cases experienced by the body, and increases this hormone during the menopause, and in the absence of ovaries, and cases of weakness and insufficiency of tubes that transport Sperm to the esophagus E, and this hormone is reduced in cases of erectile dysfunction, and cases of malfunction of the pituitary gland secretions.
- Proactin hormone: the hormone responsible for the production of milk, which is produced from the anterior lobe of the pituitary gland, which is responsible for the appearance of secondary genitalia in females, and increases the milk hormone during pregnancy and reaches the highest level after birth until the amount of milk is sufficient in the breast, Milk hormone The level of this hormone is checked in the following cases:
- Ovarian inability to produce eggs, and in cases of poor sperm production.
- Absence of menstrual cycle.
- Weak sexual desire.
- Deficiency in milk secretion in women, or milk secretion in men.
- Diseases of the pituitary gland.
- Diseases of the thyroid gland.
- Kidney and liver failure diseases.
- Pituitary gland injury.
