With the changing habits of current Brazilian society, couples have opted for late pregnancy, at an older age than before, which can result in difficulties for conception. It is known that with advancing age, the conception rate decreases and there is a higher rate of spontaneous abortions. With this, couples seek treatment for subfertility. Subfertility and infertility have numerous causes, stress being an important factor as well as current lifestyle. The collective use of birth control pills, hormones used in animals as well as exposure to toxic substances combined with a sedentary lifestyle and inadequate nutrition contribute to the increase in subfertility and infertility. The high costs of artificial insemination and in vitro fertilization techniques can make treatment unfeasible for many couples. This work aims to report some cases of human subfertility and infertility treated with Neural Therapy that obtained good results, the treatment was individualized according to each patient and their life history.

The aim of the treatment is body rebalancing and cell activation. Neural Therapy contributed to the rebalancing of patients and proved to be effective in treated patients.
