Scenario 1: Doctor: Your ovarian reserve is failing and your chances of having children are slim. The patient’s eyes immediately tear up, “So is there any medicine to eat?” Doctor: Is there any medicine that can bring her back to life when she is old? The same goes for the ovaries. The patient walks out of the clinic in despair. Scene 2: An older woman comes in for an ultrasound. She had done IVF and was pregnant, but when she was rechecked that day, she did not see a fetal heart (the fetus was not alive). Upon hearing the news, she sobbed and cried like tears. I helped her prepare for the follow-up ultrasound and was actually a bit overwhelmed. All I could say was, “Let’s try together next time, okay?” Usually, early miscarriages are due to chromosomal abnormalities in the embryo, and the miscarriage rate increases significantly with age. Modern life, school, and career often make people exhausted, thinking that they can wait until their career is successful before they conceive a child. When everything is ready, it is already too late! Common sense 1: Fertility decreases with age; infertility increases with age; miscarriage rates increase with age; delaying childbearing causes age-related increases in infertility and miscarriage rates. Data: Women at age 35 have only half the chance of having healthy offspring as women at age 25 Age 30 35 40 1-year chance of delivering a live birth 75 66 44 4-year chance of delivering a live birth 91 84 64 In general, age 35 is a clear turning point, with a significant decrease in fertility, a significant increase in miscarriage rates, and a significant increase in the proportion of malformed children. The best age for a woman to give birth is 25-30 years old. Common sense 2: Everyone’s fertility is different: In life, we can see people who are still fertile in their 40s, but we also see people who go through menopause in their 20s. (Menopause means ovarian failure and complete loss of fertility). So, just like everyone is born different in height, everyone’s fertility is different. Some people lose their fertility in their 20s and 30s, while others still have fertility in their 40s. So don’t assume that someone can still have children in their 40s, you can do it yourself. Common sense 3: The loss of fertility occurs 10-15 years before menopause. The process of ovarian aging: miscarriage – ovulatory infertility – non-ovulation, normal menstruation – menopause. Therefore, having menstruation is not the same as having fertility fertility. While career is important, family is also important, and children are the heart of the family. I have seen many people that have divorced or suffered unfairly because of infertility. If you are not a dink, if you want to have a healthy baby, then please don’t just postpone your childbearing age!
