In the journey of conceiving a new life, age is an inevitable threshold. Medically, a woman whose expected date of delivery age is ≥ 35 years old is defined as an elderly pregnant woman. That is to say, a woman around 34 years old when preparing for pregnancy has already entered the category of advanced maternal age for pregnancy. As the age increases, a woman's fertility will change significantly.

The age of 35 is a crucial dividing line. When a woman is between 24 - 30 years old, her reproductive function is in the best state, with high - quality eggs and a good endometrial environment, providing superior conditions for conceiving a new life. However, once over 35 years old, the ovarian reserve function begins to decline, the number of oocytes decreases, and the aneuploidy rate increases, which directly leads to a reduction in the pregnancy rate. At the same time, problems such as pelvic inflammation, genital tract tumors, and decreased endometrial receptivity also make the path to pregnancy more difficult. The risk of spontaneous abortion also significantly increases with age, and the decline in embryo quality subjects expectant mothers to greater psychological and physical stress. In addition, advanced maternal age pregnancy is accompanied by an increase in the risk of a series of pregnancy - related complications. The incidence of gynecological diseases such as uterine fibroids, adenomyosis, and endometrial lesions, as well as internal medicine diseases such as hypertension and diabetes, also rises significantly. Research shows that the proportion of pregnant women aged 35 and above with chronic hypertension is 2 - 4 times that of pregnant women aged 30 - 34, and the incidence of gestational diabetes in pregnant women aged ≥ 35 in China is as high as 26.7%.

However, age does not have to be an absolute barrier preventing would - be parents from having their own children. There is a family like this. Mr. and Mrs. Lin decided to have a child only after their careers were stable. At that time, Mrs. Lin was already 38 years old. They tried natural conception, but after more than a year, there was still no good news. After experiencing countless disappointments, they learned about in - vitro fertilization (IVF) technology. Through detailed consultations and examinations, under the guidance of professional doctors, Mr. and Mrs. Lin embarked on the journey of IVF. From the initial physical conditioning to ovulation induction, egg retrieval, fertilization, and embryo transfer, every step was filled with anticipation and tension.
