What is the percentage of women suffering from infertility in China and how does it compare to foreign countries? The percentage of infertile women in China is comparable to that in foreign countries, with statistics showing that it is 10%-15%, and it has been increasing year by year over the years. The more developed regions and people with high education, the higher the infertility rate, which is related to the postponement of the childbearing age. The types of infertility in patients from developed and underdeveloped regions are different, but the incidence is similar in terms of outpatient visits. Are all infertility cases suitable for IVF? Generally, a detailed examination of both the man and the woman will be done first, and some cases can be resolved with simple techniques without resorting to IVF. Only a small percentage of cases will require IVF. Are there any risks associated with egg retrieval? Will it cause damage to the woman’s ovaries, fallopian tubes and other organs? Egg retrieval itself is a medical operation and any medical operation carries some risk. Some of the problems that can occur are infection, bleeding, etc. Although the chances are very small, it is a possibility. There is no damage to ovarian function from egg retrieval. The puncture technique of egg retrieval itself does not redundantly deplete ovarian function. Many patients worry that ovulation retrieval will affect ovarian function, but in fact, a normal woman will have one egg cell ovulated every month, but the actual consumption is a dozen follicles per month. The ovarian function is not damaged and the next cycle of ovulation is not affected. However, due to the high estrogen during ovulation promotion and the addition of progesterone support later, there may be a transient high estrogen and high pregnancy, which may have some endocrine effects for two to three months.
