A woman’s chances of getting pregnant after the age of 40 are generally lower than those of a younger woman. It needs to depend on whether the ovarian function of a 40-year-old woman is normal and whether ovulation is normal. Women over 40, if the menstrual cycle is normal, follicular development is normal, ovulation is normal, generally after 40 years old can also be normal pregnancy. As age increases, the ovarian reserve function decreases and the chances of pregnancy decrease. Combinations of uterine fibroids, adenomyosis, endometrial polyps, ovarian cysts, inflammation of the fallopian tubes, hydrosalpinx, high blood pressure, thyroid disorders, diabetes, etc. may all affect pregnancy, and thus the overall chances of getting pregnant for a woman in her 40’s will decrease. If a woman over 40 needs to prepare for pregnancy, she should go to the hospital and have her doctor formulate an individualized plan for pregnancy preparation according to her specific situation. Maintain a happy mood and avoid stressful emotions.
