Because the ovaries are not removed, the body continues to produce estrogen and the symptoms of menopause are not experienced as a result of surgery but will occur naturally later in life. This technique is often used in the administration of estrogen via a patch containing estrogen. Once a woman is over 18, it should be done once a year. The pelvic examination is used to discover defects or diseases of the reproductive tract. The hormone supply doesn't stop suddenly, but it declines enough to sometimes cause irregular periods and symptoms such as vaginal dryness, frequent urination and hot flashes.
Oral contraceptives contain hormones that prevent the ovaries from releasing an egg.
Without the presence of an egg, conception cannot take place. The pituitary regulates and controls the activities of other glands and many body processes. For some women, these symptoms can be quite severe, involving a combination of emotional and physical changes. Emotional changes may include anger, anxiety, confusion, mood swings, tension, crying, depression, and the inability to concentrate. Physical symptoms include bloating, swollen breasts, fatigue, constipation, headache, and clumsiness.
