Introduction – what are the ovaries?

• The essential part of a woman’s reproductive system

• Responsible for giving a woman all of her secondary sex characteristics

• Allow women to become pregnant

• Storage of the eggs

Location of the Ovaries

• Two almond shaped glands

• Located just underneath the ends of the fallopian tubes

• are placed on either side of the uterus

Hormones Secreted • Estrogen – Steroidal hormone

• Progesterone – Steroidal hormone

Each of the hormones are constantly being produced.

Estrogen

• Promote the development of female secondary sex characteristics,

• Thickening of the endometrium • Regulating menstrual cycle • Decelerate height growth• Reduce muscle mass• Thicken the vaginal wall• Accelerate metabolism

Target Cells of Estrogen

• mammary gland, uterus, brain• Uterus – thickens the inner wall of the uterus

(endometrium) • stimulates the glands of the cervix to secrete a

particular type of mucus to allow transportation of the sperm to the uterus

• Mammary glands – stimulates the production and secretion of milk

• Brain – is responsible for the way women think and act differently from men

Feedback

Progesterone• Involved in maintaining pregnancy • Helps prepare the body for conception • Plays a role in sexual desire • Causes the endometrium to secrete special

proteins during the second half of the menstrual cycle

• Encourages the growth of milk producing glands in the breast during pregnancy

• Partly responsible for symptoms of PMS

Target Cells of Progesterone

• Uterus – secretions of the proteins, prepares it for conception

• Mammary Glands – promotes growth of the glands

• Brain – keeps desires high

Feedback

Complications due to Damages of the Ovary

• Inability to become pregnant

• All or the secondary sex characteristics would become less visible

• Menstrual cycle would stop
