A. The cause of infertility lies entirely with the female This is not a minority of cases. The World Health Organization found after a long-term study that 20% of infertility is caused purely by the male partner, 38% by the female partner, 27% by both partners, and the remaining 15% by unknown causes. Therefore, men and women with the same investigation and treatment, is conducive to find the main cause, solve the main conflict, save the cost of medical treatment and time. The causes of infertility are very complex, especially irreversible damage to the reproductive system caused by certain congenital and acquired factors, and there is no good method for treatment. Therefore, for most infertility patients, the role of doctors is only “sometimes to cure, often to help, always to comfort”. In fact, it is a kind of care to help patients to give up the choice. In fact, many infertility patients are blindly treated, which often results in the opposite treatment measures, wasting a lot of time, energy and money, and often losing the best treatment opportunities. Fourth, the disease can be cured by drugs and surgery Unknown to us, establishing a good lifestyle and having a good mindset are as important as drug and surgical treatment.
