Menopause is caused by

A) reduced synthesis of ovarian steroids despite high levels of gonadotropin hormones.
B) a decline in production of the gonadotropin hormones by the anterior pituitary gland.
C) wearing away of the uterine endometrium.
D) an increase in the blood supply to the ovaries.
E) a halt in the synthesis of gonadotropin-releasing hormone by the brain.

A) reduced synthesis of ovarian steroids despite high levels of gonadotropin hormones.

Explanation:

Menopause is characterized by depletion of ovarian follicles, a reduction of ovarian hormones to castrate levels and elevated levels of serum gonadotropins. Rather than degenerating, the reproductive neuroendocrine axis in postmenopausal women is intact and responds robustly to the removal of ovarian hormones.

Menopause marks the cessation in reproductive cycles of middle-aged women. It is heralded by depletion of ovarian follicles leading to the loss of ovarian hormones with repercussions throughout the body.

The word pulmonary means "pertaining to the lungs." It is derived from the Latin root word pulmo, which means lung. If someone has pulmonary disease, this means they have a lung disease, and that may affect their ability to breathe well.
