Because of individual differences, the time when women cannot have children varies, but most women cannot have any more children at the age of 45-55. Clinically, women cannot get pregnant again after menopause, and the majority of women experience menopause at the age of 45-55. Generally when menopause is reached, menstruation is disrupted and occasional ovulation occurs clinically, and the possibility of pregnancy still exists when intercourse is not contraceptive. Therefore, it is recommended that women entering menopause should always use contraception if they do not intend to become pregnant. If a woman has premature ovarian failure, she may not be able to conceive at an early age. If she wants to conceive, it is recommended that she should undergo ultrasound and sex hormone tests at a hospital as soon as possible, so that she can be diagnosed and treated as soon as possible. The older you are, the worse your health will be and the quality of your eggs will deteriorate accordingly. When you are over 35 years old, you can be called an advanced maternal age and the chances of miscarriage and fetal malformation will increase.
