Factors influencing penile size?

Factors influencing penile size have been explored in recent studies, revealing several intriguing points:

1. Genetic and Hormonal Influences: During embryonic development, males are exposed to dihydrotestosterone (DHT), not testosterone, which organizes the brain male. This hormone also activates during puberty, causing penile growth by its effect on penile tissue 1.

2. Environmental Factors: Rising penile length over the past three decades suggests influences beyond genetics, likely environmental. Hypotheses include exposure to endocrine-disrupting chemicals in utero, affecting early hormone signaling, and earlier onsets of puberty, which correlate with increased DHT signaling and longer penile length 1.

3. Risky Methods for Penile Enlargement: There are subcultures using combinations of dihydrotestosterone and growth hormones post-puberty to increase penile size. However, the physiological basis for such effects post-puberty is not supported, and such practices are not recommended due to safety concerns 1.

These insights provide a contemporary understanding of the factors influencing penile size, highlighting both biological processes and the potential impact of environmental factors.
