The human growth hormone has a major effect on the development of the male reproductive organs during childhood and adolescence.
Studies report that children with congenital GHD often present with micropenis and subnormal testicular size. If left untreated, the condition may persist throughout adulthood.
On the other hand, the administration of HGH early during childhood seems to reverse the process. HGH therapy in children significantly increases body height and penis length.
The scientists also point out the fact that children with congenital GHD developed micropenis even when testosterone levels were normal. Another trial confirms that HGH stimulates penile growth regardless of testosterone levels.
Does HGH make your penis bigger?
The effect of HGH on the growth of the penis and the testicles is mediated by the insulin-like growth factor 1 (IGF-1). Currently, the exact pathogenic link between the two conditions remains unknown.
HGH may be vital for normal penis growth by increasing the sensitivity of the tissued to the male sex hormones such as testosterone.
Studies in grown men report that IGF-1 levels correlated with measures of sexual function
Furthermore, in vitro experiments reveal that adequate GH levels are important for normal erectile function. The growth hormone stimulates the relaxation of the smooth muscles in the vessels of the penis, improving blood flow and erections.
However, the effect of HGH on penile growth in adults is uncertain. Only preliminary evidence from one case study reports that a combination of testosterone and HGH therapy led to a significant increase in penis size but only in patients with a micropenis (a flaccid penis less than 2.75 inches in length).
But what you can be sure of is that HGH therapy results in improved physical appearance and overall quality of life.
Do penis enlargement products work?
The most commonly advertised options include pills, lotions, exercise techniques, and massages. However, these methods do not have any scientific evidence of safety or effectiveness in increasing the size of the penis.
Vacuum pumps are sometimes used to treat erectile dysfunction, but the enlargement effect is temporary and the procedure hides long-term risks.
Preliminary scientific results suggest that stretching via a penile traction device may lead to a small increase in penis size. However, the safety of the procedure is uncertain.
The only proven way to permanently enlarge your penis is to have surgery
Surgical interventions are recommended only when there is a medical condition such as micropenis. Micropenis in adults is defined as length under 3 inches (7.5 cm).
However, the medical community does not endorse surgeries for purely cosmetic reasons. Such procedures are generally experimental and there is no guarantee for their safety or effectiveness.
