The female “fertile period” actually refers to the time when the female ovaries are capable of producing eggs for fertilization and embryo formation. A woman’s “fertile years” range from the onset of menstruation to sexual maturity to menopause and menopause, i.e. ovarian failure, which seems to be more than 20 to 30 years, but in reality, most people’s ovarian function begins to decline around the age of 35, and fertility declines significantly about 10 years before menopause. In mainland China, the legal age of marriage for women is 20 years old, and the average age of menopause for Chinese women is 48-49 years old, which means that Chinese women have about 18-20 years of “fertility” after marriage, and the best time for fertility is about 15 years. Modern society has given women an unprecedentedly wide stage, and women have more pursuits and opportunities. Most of the women who are at the peak of their fertility are in college and graduate school or “working” in society, and an inattentive pregnancy during this period often ends up in the abortion room of the obstetrics and gynecology department. When their careers are successful, they may still face the temptation and dilemma of choosing between “promotion” or “having a child”, or even having a child and ending up with multiple abortions due to the constraints of family planning policies and contraceptive failure. After deciding to have a baby, they find that they are infertile due to “tubal obstruction”, “hydrocele” and “uterine adhesion” caused by the previous multiple abortions. ” The “full liberalization of the two-child policy, the major fertility centers are crowded, most of the street wall pillar wandering doctor ads also “main treatment of infertility, after 70 80 began to willing to scatter thousands of dollars to grab back the “fertility time”, but also unwilling to accept the reality of this fertility disorder. The most common misconception is that I still have regular periods and there are still eggs on my ovaries from ultrasound monitoring, so why can’t I get pregnant? As mentioned above, the number of eggs decreases around 10 years before menopause and the quality of eggs decreases, so fertility is already low. Myth #2: First, use various methods (such as nutritional supplements, Chinese herbs, various supplements, etc.) to “regulate” your fertility for a period of time before trying to get pregnant, and then seek assisted reproduction if you are still infertile. It is an indisputable fact that the ovaries are aging every day, and it is necessary to “fight for every second” when “an inch of time is an inch of gold”. The other regimen can only promote or improve the outcome of assisted reproduction but cannot reverse the aging of the ovaries. Myth 3: Does ovulation promotion accelerate the depletion of the only remaining eggs? The growth of follicles starts from the resting state of the “stock” one by one, and ovulation promotion drugs can only work on the follicles that have already entered the developmental state. The “stock” of eggs will not be affected. Women who are nearing the end of their reproductive life often experience problems with assisted reproduction due to “low ovarian reserve” (i.e. low quantity and poor quality of eggs) and “poor ovarian response” (i.e. low follicular growth and low egg production after the use of ovulation drugs). The response to this condition is reflected in national guidelines and consensus on the concept of “fighting or scrambling” for fertility. Women with this “low ovarian reserve” (often over 35-37 years of age) are recommended to be systematically treated for “infertility” if they have been infertile for more than three months without contraception (six months in the general population). The actual key operation is to “harvest” the decreasing number of eggs from the ovaries, and if this is not possible, some “advanced” women who have failed to obtain eggs will be treated with unconventional methods of ovulation, such as “luteal phase ovulation”. “In order to help older women who have had a second pregnancy to have a healthy baby and to catch the tail end of their fertile years, the fertility centers will use the “accumulation of embryos “(i.e., freezing and storing embryos obtained from multiple egg retrievals) to increase the number of embryos transferred in a single transfer and increase the pregnancy rate.
