What is Oestrus Cycle or What is Estrous Cycle or Estrus Meaning?
The estrous cycle is the natural process that occurs in female mammals leading to the reproduction of offspring. Ovarian hormones, specifically estrogen and progesterone, fluctuate during the cycle and cause the physical changes that accompany it. The most visible sign of estrous is vaginal bleeding, which is also called estrus or heat. The estrous cycle typically lasts between four and six days, but it can vary from one animal to another.
Differences From the Menstrual Cycle
The menstrual cycle is the process that the body goes through each month in order to prepare for a potential pregnancy. The menstrual cycle is controlled by hormones, which are chemicals that are produced by the body. The menstrual cycle has four different phases: the follicular phase, the ovulatory phase, the luteal phase, and the menstrual phase.
The follicular phase is the first phase of the menstrual cycle. This phase begins on the first day of your period and ends when ovulation occurs. The follicular phase is controlled by the hormone estrogen. Estrogen causes the lining of the uterus to thicken in preparation for a potential pregnancy.
The ovulatory phase is the second phase of the menstrual cycle. This phase begins when ovulation occurs and ends when the next period starts. The ovulatory phase is controlled by the hormone progesterone. Progesterone causes the ovary to release an egg.
The luteal phase is the third phase of the menstrual cycle. This phase begins when the egg is released from the ovary and ends when the next period starts. The luteal phase is controlled by the hormone progesterone. Progesterone causes the lining of the uterus to continue to thicken in preparation for a potential pregnancy.
The menstrual phase is the fourth phase of the menstrual cycle. This phase begins when the next period starts and ends when the next period starts. The menstrual phase is controlled by the hormone estrogen.
