Drinking tea generally has no significant effect on the penis. The development of the penis is mainly related to male androgens, and most of the androgens in males mainly come from the testes, and the development of the penis in males usually develops rapidly when they enter puberty, and the development stops when they reach adulthood. Therefore, during puberty, it is important to replenish all the nutrients needed in time so as not to affect the development of the organ. Drinking tea will not have much effect on the penis, nor will it promote the development of the penis. If you find abnormalities in the development of the penis after adulthood, such as short penis or abnormal development, you should go to the hospital in time, and under the guidance of the doctor for treatment.
