Hormones control the menstrual cycle right or wrong?

The answer is: right.

Hormones play an important role in controlling the human menstrual cycle. A complex interaction of hormones such as luteinizing hormone and follicle-stimulating hormone, produced by the pituitary gland, regulates the cycle. During menstruation, the uterine lining thickens and then sheds. Hormonal imbalances can cause irregular periods, and a decrease in sex drive often occurs after natural or surgical menopause. Obviously, hormones are necessary to control the menstrual cycle.
