Human Endocrine System

The hormone human chorionic gonadotropin (better known as HCG) is produced during pregnancy. It is made by cells that form the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall.

Progesterone is a steroid hormone involved in the female menstrual cycle, pregnancy (supports gestation) and embryogenesis of humans and other species. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen.

Thyroxine production requires the presence of iodine.

Insulin is a hormone secreted by the pancreas. It plays a key role in the regulation of blood glucose levels.

Adrenals also produce the hormone adrenalin. It helps the body to adjust to stress when one is very angry, embarrassed or worried.

The hormone secreted by Leydig cells is testosterone.

Lutinising Hormone stimulates leydig cells for secreting testosterone.

Presence of human chorionic gonadotropin (hCG) hormone is the basis for pregnancy testing.

Luteinizing hormone induces ovulation in females.

Hormones produced by pancreas are polypeptides in nature.

Prolactin (PRL)  is a protein that is best known for its role in enabling female mammals to produce milk.

Gastrin, secretin and cholecystokinin are all gastrointestinal hormones. They control various functions of the digestive organs.

Lutenising hormone helps in promoting spermatogenesis and ovulation.
