How Penile Growth Works (And When)
Penile development is driven by androgen signalling (testosterone → dihydrotestosterone via 5-α-reductase) in utero and again at puberty. That surge activates androgen receptors in penile tissues, producing longitudinal growth and girth. Once puberty completes, additional androgen exposure does not further lengthen the organ in eugonadal men. Review articles in andrology/urology repeatedly note this timing dependence: adult administration of androgens changes libido and erectile function — not size.
What About DHT Specifically?
Topical DHT gel has been studied in prepubertal boys with partial androgen insensitivity or "micropenis," showing increased penile length while therapy continues. These are pathology- and age-specific uses; there is no robust evidence that DHT increases penile size in adults after normal puberty.
Anabolic Steroids (AAS): Performance Up, Penis Unchanged
AAS users often report:
-
Higher libido initially
-
Testicular atrophy with prolonged use
-
Suppressed spermatogenesis
-
Erectile issues
High-dose androgens do not enlarge an adult penis; the androgen receptors that mediate pubertal penile growth are not a volume knob you can keep turning post-puberty. Large trials of late-onset hypogonadism (e.g., the NEJM Testosterone Trials) showed improvements in:
-
Sexual function
-
Mood
-
Hematocrit
-
Bone density
Not penile dimensions.
Growth Hormone (GH)/IGF-1: Physiology vs Reality
The GH–IGF-1 axis:
-
Supports general somatic growth
-
Has cellular effects on smooth muscle and fibroblasts
In GH-deficient boys, GH (sometimes with gonadotrophins/androgens) can help normalise penile size. But in GH-replete adults, giving GH:
-
Does not elongate the penis
-
Mainly alters:
-
Body composition
-
Fluid balance
-
IGF-1 levels
-
-
Carries non-trivial risks:
-
Edema
-
Carpal tunnel
-
Insulin resistance
-
Micropenis vs Normal Variation: Don't Conflate Them
-
Micropenis definition: Stretched penile length < –2.5 SD for age
-
Management: Early androgen therapy (short testosterone or DHT courses) in childhood where indicated
-
Important: Translating pediatric protocols to healthy, fully mature adults is not evidence-based
What Can Change in Adults?
-
Erections: Androgens can improve:
-
Libido
-
Erectile parameters in hypogonadal men
-
-
Agents like:
-
PDE5 inhibitors
-
PT-141
Can modulate arousal/erectile response
-
This is functional change, not morphological. (The Testosterone Trials highlight function benefits without structural penile changes.)
Risks of Chasing a Non-Existent Outcome
-
AAS:
-
Gonadal suppression
-
Erythrocytosis
-
Dyslipidaemia
-
Hypertension
-
Hepatic strain
-
Psychiatric effects
-
-
High-dose or non-indicated GH:
-
Edema
-
Arthralgia
-
Insulin resistance
-
Potential neoplasia signalling concerns
-
-
Unregulated "DHT creams/sprays":
-
Contamination risks
-
Variable dosing
-
No evidence of adult penile tissue enlargement
-
Clinical Bottom Line
No high-quality evidence supports that steroids, DHT or HGH will increase penis size in healthy adult men. Where hormones help (true pediatric endocrine pathology), they do so because:
-
Treatment coincides with a developmental window
-
Corrects a deficiency
Not because the molecules are magic.

your advisor information indicates that with some minor exceptions, steroid therapy hardly contributes to the elongation of a penis. First, please clarify if I am correct in this assumption. Second, my problem is with the complete loss of sperm upon ejaculation, which I can only assume is a total lack of Testosterone development along with loss of Libido and along with Erectile Dysfunction. If I am correct in this, can your service/therapy help me without aftereffects. Please let me know if there are any. I should also record that in past times, I had an enormous Testosterone and libido development along with natural erections. Now all of that is gone. There is nothing. If your service/therapy can correct this sexual deficiency would that contribute in some minor way to the elongation of my penis length? And if is so how much? Third, I must record, that my described sexual deficiency has had a Psychological effect on me,and I am anxious to correct it. Now, if you can help me then please let me know how and, for how long and the financial cost for your service. Thank you Post Script: I will be busy all day tomorrow. But I would reply tomorrow night.
