Oestrous cycle
Menstrual cycle
The females of placental mammals exhibit cyclical changes in the activities of ovaries and accessory ducts as well as hormones during the reproductive phase. These cyclical changes during reproduction, in non primate mammals like -cow, dogs are known as oestrous cycle.
The ovary releases one egg every month. The uterus also prepares itself every month to receive to receive a fertilized egg. The inner uterus lining (endometrium) becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilized, then the uterus lining is not required. Hence, it breaks down and is released in the form of blood and mucus through the vagina. This process lasts for 2-8 days. This cycle occurs every month and is known as menstruation. Hence, the menstrual cycle is the reproductive cycle in the female body. It begins with the onset of puberty.
yes
18 to 21 days and conception occurs on 3rd day of cycle
The estrous cycle of pigs is 21 days. Humans have a menstrual cycle which can last from 21-35 days.
The first season can be at six months old and then usually two seasons a year after that.
Yes, you would still get your period if you hump something.Menstruation is controlled by your menstrual cycle, masturbation has no impact on this.
The menstrual cycle starts on day one of menstruation, on average menstruation lasts between 5-7 days. Thus between days 1-6 of the menstrual cycle you're menstruating.
Oestrus cycle are present is most of the mammals. The females becomes sexually receptive during the oestrus phase. They express the desire for mating at this stage. In case of the humans the females are more receptive at the time of ovulation. But there are many exceptions. In case of the oestrus cycle the endometrium is reabsorbed. In case of the menstruation the endometrium is shed away to give the phenomena called as menstruation.
No. Only humans and closely related species such as chimpanzees have a period or menstrual cycle. Other mammals that have a placenta have a similar oestrous cycle, where the lining of the uterus is built up in case of pregnancy over a specific time cycle, but they don't shed the lining of the uterus as blood in the way humans do, they simply reabsorb the unused uterus.
First of all, it's menstrual. Second is the menstrual cycle is the time space between periods hope that helps! :)
The term fertile means when you are able to get pregnant. During a typical menstrual cycle of 28 days a woman would likely be fertile between days 7-16 of the menstrual cycle.
The menstrual cycle is the reproductive cycle, as long as she is fertile she is always on her menstrual cycle. You can't tell where she is in her menstrual cycle unless she tells you.

The menstrual cycle is the cycle of hormonal changes between your reproductive organs and brain that cause ovulation and in turn failing fertilisation causes menstruation. It is not possible for a menstrual cycle to last only two days.
Yes, the ovulatory cycle and menstrual cycle are the same thing. Both talk about the reproductive cycle, but one focuses on ovulation as the main feature of the cycle and the other focuses on menstruation as the main feature of the cycle. There is no difference between these two cycles.
A menstrual period is when there is a loss several tablespoons of blood and mucus from the vagina; when a menstrual cycle is the series of changes a woman's body goes through for pregnancy.
wow can i accelerate menstrual cycle?
Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system. During the menstrual cycle an egg is released and to prepare for possible pregnancy the uterus lining plumps-up, if pregnancy doesn't occur the uterus lining sheds (menstruation) so it can start afresh again next cycle.
