There is no such thing as “genital growth factor”. The size of the genitals varies greatly from individual to individual, generally after adulthood, the genitals will not develop again, and there is no special drugs, health care products can promote the secondary development of the genitals, we must correctly understand, do not believe in the advertisements, the indiscriminate use of health care products. If you do have a short penis, you need to check whether you have a prepuce, hidden penis and hormone secretion abnormalities and other diseases, if there are these developmental abnormalities, you should go to the hospital in time to take measures such as surgery. If you are still in puberty, there is still room for the penis to grow and develop naturally, so there is no need for special treatment. You should adjust your mindset, correctly understand, and go to the regular hospital in time for medical treatment. Don’t believe in advertisements, health products, prescriptions and so on.
