For women, they will go through many different stages in their lives, including their menstrual cycle and their menstrual period every month. However, at a certain age, women may also experience menopause! This is normal for women, so is it normal for a 44 year old woman to experience amenorrhea?
Under normal circumstances, the age of menopause for women is generally between 44-54 years old, and premature or late menopause may pose risks to physical health. The average age of menopause for urban women in China is 49.5 years, while for rural women it is 47.5 years. The age range for menopause can be between 35-55 years old, with American women reaching 51.4 years old. The age range for menopause can be between 48 and 55 years old. In recent centuries, there has been a trend of early onset of menstruation, but the change in menopausal age is not significant. Menopause before the age of 40 is called "premature menopause" or "premature ovarian failure". About 1% of women experience menopause before the age of 40 and after the age of 55, known as' delayed menopause '.
Research has found that women with long-term malnutrition, short stature, and light weight have an average menopausal age of 43.6 years for the former and 47.3 years for the latter, compared to women with good nutrition, relatively tall bodies, and relatively heavy weight. Smoking is also a major factor contributing to early menopause. Benzopyrene in cigarettes is a lethal factor for oocytes. Animal experiments have shown that low-dose benzopyrene can destroy 25% of oocytes, while high-dose benzopyrene can destroy 98% of oocytes.
