Can I still try again after 3 failed IVF attempts?

Patient's question:

My sleep isn't very good, but other things are relatively okay. The problem is that I've been married for 12 years and have never been pregnant. Shortly after getting married in 1998, I started feeling something was wrong and initially thought it was my husband's issue. I sought medical help everywhere. In 2007, I was diagnosed with blocked fallopian tubes on both sides at the Chengdu Family Planning Guidance and Examination Center and underwent laparoscopic adhesiolysis at the same time. The following year, when I had another check-up, I found that the tubes were blocked again. From 2008 to 2009, I underwent three rounds of in vitro fertilization (IVF) at the Second Affiliated Hospital of West China University in Chengdu, all of which failed. The first time, the doctor said there was fluid in the fallopian tubes and suggested a (puncture). We used all imported drugs, but it didn't work. The second time, still holding onto hope, it didn't succeed either, and we used all domestically produced drugs. The third time, we switched to a doctor who was considered quite authoritative by many, but it still didn't work, and we used domestically produced drugs. 09

Doctor's answer:

The success of IVF primarily depends on whether there are good eggs, embryos, and an endometrial environment, all of which are determined by the female's physical condition. Additionally, the optimal age for IVF is between 30 and 35, and the success rate decreases after the age of 40. Age is the main factor, and the success rate of IVF is around 30%.
We recommend the US-China STK Fertility Mirror technology. The STK ultra-minimally invasive nanofiber has a diameter of only one-millionth of a millimeter. Through local nanofiber intervention in one go, it can comprehensively address issues in the uterine cavity, cervix, ovaries, pelvic cavity, and fallopian tubes. This significantly enhances the safety of interventional ( means "dredging" or "" in this context, referring to clearing blockages) and diagnostic treatments for infertility, improving the pregnancy rates of infertile patients. It is an internationally recognized leading minimally invasive technology for infertility in the medical field today.
