Patient's question:
The first and second generations of test-tube baby surgery both failed. What are the common reasons that can lead to this phenomenon? What are the remedial measures? Which hospital is relatively authoritative in treating this?Doctor's answer:
Reasons for IVF failure:1. 20% of fertilized eggs fail to develop normally or undergo degenerative changes, making them unsuitable for transfer back into the uterine cavity.
2. The embryo has been transferred into the uterine cavity, but fails to implant and result in pregnancy. Failure may be followed by a 3-month waiting period before another attempt.
3. The female does not respond well to ovulation-stimulating drugs, leading to insufficient production of mature eggs by the ovaries. Alternatively, special anatomical reasons in the female's pelvic cavity may make egg retrieval difficult or impossible.
