The key difference between the menstrual cycle and the estrous cycle is that the menstrual cycle occurs in humans and some primates, while the estrous cycle occurs in most other mammals. In the menstrual cycle, females have a monthly period of bleeding, while in the estrous cycle, females experience a period of sexual receptivity known as "heat" or "estrus." Additionally, in the menstrual cycle, females can conceive at any time during their cycle, while in the estrous cycle, females are only fertile during specific times when they are in estrus.

Yes, withdrawal from certain substances or medications can affect your menstrual cycle. Stress and hormonal changes due to withdrawal can lead to irregular periods or changes in menstrual flow. Additionally, changes in lifestyle or body weight during withdrawal can also impact the regularity of your cycle. If you have concerns about your menstrual health during withdrawal, it's best to consult a healthcare professional.
Guys do not have periods because they do not have a menstrual cycle. Guys do not experience the same hormonal changes and shedding of the uterine lining that occurs during a menstrual cycle in females.
The key difference between the estrous and menstrual cycle in female reproductive physiology is that the estrous cycle is common in most mammals, where females are only receptive to mating during a specific period of time when they are in heat. In contrast, the menstrual cycle is unique to humans and some primates, where females have a monthly cycle of ovulation and menstruation, regardless of mating opportunities. Additionally, the estrous cycle does not involve shedding of the uterine lining like the menstrual cycle does.
The menstrual cycle feedback loop involves the interaction of hormones like estrogen and progesterone to regulate the changes in a woman's monthly cycle. These hormones are produced by the ovaries and signal the uterus to prepare for potential pregnancy. If pregnancy does not occur, hormone levels decrease, leading to the shedding of the uterine lining, which results in menstruation. This feedback loop helps maintain the balance of hormones throughout the menstrual cycle.

Human females have menstrual cycles so that they can get pregnant, and thus continue the human race! During the menstrual cycle a woman will ovulate and the uterus will prepare itself for the possibility of pregnancy, if pregnancy doesn't occur the uterus lining sheds and the process starts again.
Menstruating is the time when a female bleeds during her monthly period, called her "menstrual cycle.
The menstrual cycle is the monthly cycle that prepares a female's body for potential pregnancy. It typically lasts about 28 days, during which hormonal changes lead to the maturation of an egg and the thickening of the uterine lining. If fertilization occurs, the egg implants in the uterus; if not, the lining sheds, resulting in menstruation, and the cycle begins anew.
