The first step is to boost immunity. The cause may come from a bacteria in the testicles, or it may be cellular. Therefore, it will be necessary to use hormones, as well as oils like castor oil, sesame oil, garlic oil, or rose oil. The affected person can mix them and combine them with a vegetable oil such as sweet almond oil or argan oil, and make poultices with them to leave on for fifteen minutes. In addition, massaging around the testicles with these oils will also bring benefit.
Of course, supplications are important, for Allah is capable of all things. Also, taking vitamins A, C, and E, as well as selenium or arginine, will provide help, and they are found today in dietary supplements to improve fertility.
Furthermore, one should not forget to use honey combined with palm pollen, royal jelly, and black seed (Nigella sativa) (haba sawda).
Finally, wheat germ capsules, a source of vitamin E, will be effective in helping the proper functioning of the cells in the testicles.
