What hormone causes ovulation to occur in the menstrual cycle?
The hormone that causes ovulation to occur in the menstrual cycle is called luteinizing hormone (LH).
Can a man have a menstrual cycle?
No, only individuals with female reproductive systems can have a menstrual cycle. Men do not have the necessary biological structures for menstruation.
What are the key differences between the estrous and menstrual cycle in female reproductive physiology?
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.
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.
What are the key differences between the menstrual cycle and the estrous cycle in female reproductive physiology?
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.
