"The word “menopause” derives from the Greek “men” (month or monthly cycle) and “pausis” (end, stop)"<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5558404/#:~:text=Studies%20have%20shown%20many%20factors,activity%2C%20unilateral%20oophorectomy%2C%20serum%20lead</ref>, menopause is the permanent cessation of the menstrual cycle in women without any pathological causes because of physiological deficiency production of estrogen hormone in women."It occurs at an average age of 52 years, but the age of natural menopause can vary widely from 40 to 58 years".<ref>http://www.menopause.org/docs/default-source/2014/nams-recomm-for-clinical-care.pdf</ref> it is considered a natural end to fertility in women. Menopause is a date: the day after a woman's last period ever finishes. In common everyday parlance, however, the word "menopause" is usually not used to refer to one day, but the whole of the menopause transition years. This period time is also referred to as the change of life or the climacteric, "we should consider that 'menopause' is referring to a specific event, the cessation of menses, and 'climacteric' to gradual changes of ovarian function that start before the menopause and continue thereafter for a while". <ref name="pmid23998690">{{cite journal| author=Blümel JE, Lavín P, Vallejo MS, Sarrá S| title=Menopause or climacteric, just a semantic discussion or has it clinical implications? | journal=Climacteric | year= 2014 | volume= 17 | issue= 3 | pages= 235-41 | pmid=23998690 | doi=10.3109/13697137.2013.838948 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23998690  }} </ref> And more recently is known as "perimenopause", (literally meaning "around menopause").
