Recently, many of my friends asked me about the indications for IVF and who needs IVF: 1. Obstacles to egg transport caused by various factors on the female side. 2, Ovulation disorder. 3, endometriosis. 4.Male oligospermia and weak spermatozoa. 5, Infertility of unknown cause. 6.Immune infertility. Female fertility decreases significantly after greater than 35, and the natural pregnancy rate is low in patients of advanced age greater than 38 years old, and patients who need to be pregnant should be seen promptly.
