Is Penis Size Genetic and Can It Be Increased

Have you ever wondered why someone else’s penis is bigger than yours? Or why yours is more prominent than theirs? The scientific answer is genetics. Genes are building blocks that determine a living organism’s behavior and appearance. This is what forms the basis of genetics.


Genetics play a substantial role in the size of a penis, but genes are not only responsible. Fortunately, if you are not satisfied with the size of your penis, using penis enlargement products can increase your penis size, whether you are worried about length or girth.

Which Genes Affect Penis Size

Genes Affect Penis Size

A male child inherits one Y chromosome from their male parent and one X chromosome from their female parent. The Y chromosome carries the genes which determine the growth of the male reproductive organ.

Although the Y chromosome leads to the development of the penis and testes, it doesn’t control the penis size. The X chromosome is responsible for the length and shape of the penis. The Y chromosome houses about 70-200 genes, while the X chromosome harbors 900-1400 genes: this difference explains why siblings with the same biological parents may have varying penis sizes since each sibling may inherit a different X chromosome from their mother.

Genetic mutations and rare conditions like Klinefelter syndrome and Kallmann syndrome can sometimes affect penis size. Also, de novo genes, unique to you and a bit different from your parents, can play a part in penis size.

Other Factors That Affect Penis Size

Factors That Affect Penis Size

Penis size does not solely depend on parental or unique genes. There are also non-genetic factors that affect penis size:

  • Environment: Environmental pollutants, such as plasticizers, pesticides, and chemicals, may harm penis size. These toxic chemicals act as endocrine disruptors, which affect the production of hormones crucial for reproduction. Exposure to these chemicals during pregnancy can negatively impact the development of sexual organs in male newborns.
  • Hormones: Male sex hormones contribute to penile and testicular growth. Testosterone causes the penis to grow in length at puberty. Low testosterone levels are linked to smaller penis size, lower libido, and erectile dysfunction. Exposure to environmental estrogens (female sex hormone) during puberty may cause penile abnormalities.
  • Nutrition: Malnutrition in the womb, early childhood, and adolescence, as seen in bulimia or anorexia, can delay normal puberty.
  • Smoking and Tobacco Use: Smoking reduces blood flow around the body. It can reduce the size of an erect penis because it affects the production of elastin responsible for erection.
  • Stress: High level of stress reduces the size of your penis. Too much stress reduces blood flow to the penis leading to small size and issues relating to sexual health.

Penile enhancement products produce excellent results. Nonetheless, avoiding factors that can affect your penis size negatively is essential.
