The word "estruation" describes the menstrual cycle of non-human animals such as dogs and cats. Its spelling is derived from the Latin word "oestrus", meaning heat or sexual desire. The phonetic transcription is ɛˈstrueɪʃən, with stress on the second syllable. It begins with the short "e" sound followed by "s-t-r-u" and ending in "a-t-i-o-n". The "sh" sound is formed by the combination of "t" and "i" while the "u" in "estru" is pronounced as a "yoo" sound.
Estruation refers to the process of temporary cessation or suppression of the normal menstrual cycle in females. It is characterized by the absence of menstrual bleeding for a certain period of time, typically due to physiological changes or certain medical conditions.
During estruation, the ovaries temporarily stop producing and releasing eggs, and the lining of the uterus does not shed as it normally would during menstruation. This interruption in the menstrual cycle can occur for various reasons, including pregnancy, breastfeeding, hormonal imbalances, certain medications, extreme stress, or medical procedures that affect the reproductive system.
Estruation is different from menopause, as it is a temporary condition. Menopause, on the other hand, refers to the permanent cessation of menstruation in women, typically occurring around the age of 45 to 55 years. It is important to note that estruation can also occur in women who have reached menopause due to hormonal therapies or medical interventions.
Although estruation is a natural process during certain life stages, it can also be a symptom of an underlying health issue. Therefore, if a woman experiences estruation without an obvious cause, it is advisable to consult a healthcare provider for further evaluation and diagnosis.
In summary, estruation is the temporary halt of the normal menstrual cycle in females, either due to physiological changes or specific medical conditions. It is different from menopause, being a reversible condition that can occur during various life stages and may require medical attention for proper management.
