The
oestrous cycle
refers to the reproductive cycle in mammals, including humans. This cycle is regulated by the fluctuations of hormones such as estrogen and progesterone.During the oestrous cycle, the female reproductive system goes through several phases, including
proestrus
,estrus
,metestrus
, anddiestrus
. Each phase is characterized by specific hormonal changes and physical signs.Ovulation occurs during the estrus phase, when the female is most fertile. This is the optimal time for mating and conception to take place.
The length of the oestrous cycle varies between species. In most mammals, it typically lasts between 21 to 28 days, but some species may have shorter or longer cycles.
During proestrus, the levels of estrogen begin to rise, preparing the reproductive system for ovulation. This is followed by estrus, the phase of sexual receptivity when the female is ready to mate.
Metestrus and diestrus are the final phases of the cycle, characterized by a decrease in estrogen levels and an increase in progesterone. If fertilization does not occur, the female will enter a period of diestrus before the cycle starts again.
Hormonal imbalance can disrupt the oestrous cycle, leading to irregularities in menstruation and fertility. Conditions such as polycystic ovary syndrome (PCOS) can affect hormone levels and the regularity of the cycle.
Understanding the oestrous cycle is essential for reproductive health and fertility management in both human and animal populations. Hormonal fluctuations play a crucial role in the regulation of ovulation and the menstrual cycle.
