Penis size is genetically determined. Once you are finished with puberty there is no chemical, drug or supplement that will cause growth. There is an expensive surgery that can add some length and you can get injections of Restylene for width. If you are concerned that your penis is too small then find a smaller girl. Vagina size varies quite a bit just like penis size.
Appositional growth occurs on the surface of bones and adds a series of layers to increase the diameter or thickness.
Biochemicals enter the body through various means such as ingestion of food and drink, inhalation of air, and absorption through the skin. Once in the body, these biochemicals are processed by various organs and cells to carry out important functions such as energy production, growth, and repair.
Primary growth in plants adds length to the stems and roots through cell division in the apical meristems. Secondary growth, on the other hand, adds girth to the stems and roots through cell division in the lateral meristems, such as vascular and cork cambium.
Yes, penis does affect radiation.

Your penis is pretty tough and grows at its own rate. There is not much that will hurt its growth. Also not much that improve its growth.
Biochemicals that help in cell growth are primarily stored and synthesized in various types of cells and tissues. Key examples include growth factors, hormones, and nutrients like amino acids, vitamins, and minerals. These substances are often stored in specialized organelles or compartments, such as vesicles, and are released into the extracellular environment to promote cellular proliferation and development. In addition, the extracellular matrix provides structural support and also contains signaling molecules that facilitate cell growth.
Smoking
Yes.
Of course, homones start the process of penis growth, but the final size is determined by genetics . . . you inherit penis size from your parents.
Maybe, but it won't stunt your growth
In animal cells, biochemicals that aid in cell growth are primarily stored in the endoplasmic reticulum (ER) and Golgi apparatus. The ER synthesizes proteins and lipids essential for cell structure and function, while the Golgi apparatus modifies, sorts, and packages these molecules for transport. Additionally, lysosomes store enzymes that break down cellular waste and recycling materials, contributing to overall cell health and growth.
