In the previous study session you learned about the anatomy and physiology of the female reproductive system.

Maternal physiological changes in pregnancy

Ross, L. It has been suggested that pregnant women are less sensitive to the action of ADH because they possess an inactivating mechanism for this hormone. This hypothesis was tested by studying the effects of intravenous administration of Pitressin on renal hemodynamics and water and electrolyte excretion in pregnant women in the latter part of gestation and in postpartum and nonpregnant subjects. During pregnancy, a single intravenous dose of milliunits m. Potassium excretion was inconsistent. Osmolal and free water clearances fell, the latter becoming negative in most instances.

In addition to their role in producing ova, the ovaries also have the distinction of being an endocrine gland because they secrete hormones—primarily estrogen and progesterone—that are vital to normal reproductive development and fertility. Estrogen replacement therapy during menopause protects bone mass and helps protect against the risk of osteoporotic fractures. Treatment for ovarian cysts depends on the size and type of cyst.

You and Your Hormones

Progesterone , hormone secreted by the female reproductive system that functions mainly to regulate the condition of the inner lining endometrium of the uterus. Progesterone is produced by the ovaries , placenta , and adrenal glands. The term progestin is used to describe progesterone and synthetic steroid hormones with progesterone-like properties, such as the progestogen levonorgestrel. In the ovaries the site of progesterone production is the corpus luteum. Progesterone prepares the wall of the uterus so that the lining is able to accept a fertilized egg and so that the egg can be implanted and develop. It also inhibits muscular contractions of the uterus that would probably cause the wall to reject the adhering egg. A fertilized egg that becomes implanted in the uterus will form a placenta.

The correct balance of hormones is essential for a successful pregnancy. Hormones travel around the body, usually via the blood, and attach to proteins on the cells called receptors — much like a key fits a lock or a hand fits a glove. In response to this, the target tissue or organ changes its function so that pregnancy is maintained. Initially, the ovaries , and then later, the placenta , are the main producers of pregnancy-related hormones that are essential in creating and maintaining the correct conditions required for a successful pregnancy. Following conception , a new embryo must signal its presence to the mother, allowing her body to identify the start of pregnancy. When an egg is fertilised, it travels though the female reproductive tract and on day six implants into the womb releasing a hormone called human chorionic gonadotrophin in the process. This hormone enters the maternal circulation and allows the mother to recognisethe embryo and begin to change her body to support a pregnancy.

Pregnancy is a rollercoaster of shifting hormone levels which can have numerous effects. This graphic looks at six key hormones during pregnancy, their roles in the development of the baby, and other effects. Human chorionic gonadotropin hCG hCG is an important hormone in early pregnancy. The corpus luteum is a temporary structure in the ovaries which produces other key hormones during early pregnancy. Its concentration increases from conception and peaks 8—11 weeks after. For the first few days after conception its levels are too low to detect with pregnancy tests, but after implantation its levels double every 48 hours. Progesterone During the early weeks of pregnancy, the corpus luteum produces progesterone.


Supportive care in early pregnancy is associated with a significant in the drug's safety and efficacy profile in different trimesters of pregnancy.

You and your baby are born with the ability to start labor, labor and give birth, breastfeed and become deeply attached to each other. The flow of hormones in your body drives these well-organized, finely tuned processes. It is important that you and your maternity care providers understand how to work with — and avoid disrupting — these processes.

The endocrinology of human pregnancy involves endocrine and metabolic changes that result from physiological alterations at the boundary between mother and fetus. Progesterone and oestrogen have a great role along with other hormones. The controversies of use of progestogen and others are discussed in this chapter.

Hormones During Pregnancy

Вскоре после не получившего огласки, но причинившего колоссальный ущерб государственной безопасности проникновения в базы данных Военно-морского флота стало абсолютно очевидно, что секретная информация, хранящаяся на компьютерах, подключенных к Интернету, перестала быть тайной. По предложению министерства обороны президент подписал тайное распоряжение о создании новой, абсолютно безопасной правительственной сети, которая должна была заменить скомпрометировавший себя Интернет и стать средством связи разведывательных агентств США. Чтобы предотвратить дальнейшее проникновение в государственные секреты, вся наиболее важная информация была сосредоточена в одном в высшей степени безопасном месте - новой базе данных АНБ, своего рода форте Нокс разведывательной информации страны.

Oestrogen helps the uterus grow and maintains its lining. It supports foetal development, including the development of organs and bodily systems. It also activates and regulates the production of other important pregnancy hormones. Prolactin is the main hormone needed to trigger the production of breast milk.

Maternal physiological changes in pregnancy are the adaptations during pregnancy that the pregnant woman's body undergoes to accommodate the growing embryo or fetus.
