The Moon.
The moon controls ALL water on the Earth, since human bodies are 60% water the Moon also controls our bodies.
The word "menstruation" is etymologically related to "moon". The terms "menstruation" and "menses" are derived from the Latin mensis (month), which in turn relates to the Greek mene (moon) and to the roots of the English words month and moon-reflecting the fact that the moon also takes close to 28 days to revolve around the Earth (actually 27.32 days). The synodical lunar month, the period between two new moons (or full moons), is 29.53 days long.

MaxineThe human menstrual cycle is regulated by hormones produced by the hypothalamus, pituitary gland, and ovaries. The hypothalamus secretes gonadotropin-releasing hormone (GnRH), which prompts the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH and LH then stimulate the ovaries to produce estrogen and progesterone, which regulate the menstrual cycle.

What is the menstrual cycle controlled by?
The menstrual cycle is controlled by hormones, specifically estrogen and progesterone, which are produced by the ovaries. These hormones regulate the different phases of the menstrual cycle, including ovulation and menstruation. Additionally, the hypothalamus and pituitary gland in the brain play a role in controlling hormone production.
Is menstrual cycle a feedback mechanism?
Yes, the menstrual cycle is a feedback mechanism controlled by hormones. The cycle involves the feedback interactions between the hypothalamus, pituitary gland, ovaries, and uterus to regulate the release of hormones such as estrogen and progesterone, which influence the development and shedding of the uterine lining.
Which structures in the human body are directly affected by the hormones involved with the menstrual cycle?
The hormones involved in the menstrual cycle primarily affect the uterus, ovaries, fallopian tubes, and menstrual lining (endometrium). These hormones regulate the growth, shedding, and repair of these structures during the menstrual cycle.
How long is woman's menstrual cycle?
A woman's menstrual cycle typically lasts between 21 to 35 days, with the average being around 28 days.
What happens to the uterus during a menstrual cycle?
During a menstrual cycle, the uterus thickens its lining in preparation for a possible pregnancy. If pregnancy does not occur, the uterus sheds this lining through menstruation. The cycle is controlled by hormones such as estrogen and progesterone.
