Abstract:
Fourteen adult men volunteered to participate in an experiment to evaluate the potential for penile growth
as a result of taking 50,000 units of vitamin D 3 and 100 mcg of vitamin K 2 daily. Penis length increased
an average of 0.46 inches and circumference increased an average of 0.523 inches, both statistically
significant. These results are comparable to those obtained with use of a vacuum pump or with surgical
augmentation. We suggest that men interested in penis augmentation consider this much simpler and safer
approach when they are interested in penis enlargement.
Key Words:
D 3, penis augmentation. libido enhancement
Introduction:
Penis size is one of the major psychological concerns of men.1,2,3 Indeed, only 55% of
men, in one study, were satisfied with their penis size.1 Penis size, even among
heterosexual men, equals concerns about weight and height.4 Lay literature and the large
number of e-spam ads for penis enlargement, as well as surgical penis enlargement
techniques, further emphasize the significant interest in penile enhancement. Other than
surgery, only two other reports of successful penis enlargement have been located.5,6
The current study was undertaken when one of the authors (JP) reported that male
patients had reported spontaneously that they had noticed penis growth after taking
vitamin D 3 for immune enhancing benefits.
Research design:
Fourteen male friends were invited to participate in a research project. They signed an
informed consent form which explained the project and agreed to have blood drawn
initially and whenever possible at 3 and 6 months after taking daily 50,000 units of D 3
and 100 mcg of vitamin K 2. K 2 is generally considered to be synergistic with D 3 in
enhancing deposits of calcium into bone. They were instructed to take no calcium
supplements while on the D 3. They also agreed to have the senior author measure their
flaccid stretched penis or to provide digital photos showing length and circumference of
their erect penis initially and at 3 and 6 months.
Results:
Virtually all the men reported both increased general energy, as well as enhanced libido.
There were no reports of adverse symptoms. Calcium levels remained within the normal
range.

* These were 6-month measurements. The rest were 3 months. In general, the growth during the
second 3 months was about half that of the first 3 months.
Those with circumferences were obtained by having the subject do digital photos with measurements of
length and circumference. Those without circumference were stretched flaccid lengths.
Average length initially was 6.23 inches and at conclusion was 6.69 inches; an average increase of 0.46
inches, ranging from 0.12 to 0.9 inches
Average circumference was initially 4.863 inches and at conclusion was 5.38 inches, increasing an
average of 0.523 inches, ranging from no change to a maximum of 1.5 inches. Statistical analysis via the
paired samples t-test, or repeated measures t-test, reveals that there were significant increases in both
penis length (n=14 pairs of measurements, t=-6.54, p<.001) and circumference (n=9 pairs of
measurements; t=-3.179, p=.013) in those participating in the Vitamin D regimen. See t-test results in
the T-Test Chart.
This includes both 3-month and 6-month participants, as the sample size is too small to
evaluate them separately.
Discussion:
The two earlier studies, which demonstrated penis enlargement,5,6 used vacuum pumps that required 30
minutes of daily vacuum pumping to achieve enlargement of up to 1 inch in length (average 0.67 inches)
up to 0.75 inches in circumference (average 0.55 inches). Interestingly, it is reported that surgical
enhancement results in only 1-2 cm increase in length and 2.5 cm augmentation in circumference!7
In the current study, average increase in length of 0.46 inches and circumference of 0.523 inches is
highly statistically significant and approximately equal to that obtained with vacuum pumps or surgical
augmentation.
The range of penis sizes in this small sample is similar to that reported by Kinsey in his measurement of
5000 men8, with 54% of men having a penis length of 6 or less inches and 99.4% having a length of 8 or
less inches. More recent articles have reported even less generous lengths!9,10
The only known risk of large dosages of vitamin D 3 is excessive blood calcium levels with potential
kidney damage. For that reason, individuals taking the large dosage of D 3 are advised to avoid calcium
supplements. In this current study, serum calcium levels at 3 and 6 months were all within the normal
range.
The physiological explanation for apparent androgenic effects of vitamin D 3 are not simple, although
plasma levels of vitamin D metabolites have been reported to have an effect upon sexual maturation and
growth.11 There is some evidence that vitamin D 3 is an androgen agonist and binds to Androgen
Receptors.12,13 Much further work will be needed to explore this as a possible mechanism for enhanced
penis augmentation with vitamin D.

A review of medical and psychological literature reveals that the most common concern among males is inadequate penis size. There has been, to this date, very little published in the medical literature on the subject of penis size. Current studies done on 7 adult males replicated those reported in England by Dr. Brian Richards. In the 7 males there was an average increased length in the penis of 0.67 inches, and an average circumference increase of 0.5 inches. The technique is worth considering in those individuals who have psychological concerns about penis adequacy.

The media equate a man's penis size with his power and masculinity. Views about penis size were assessed in an Internet survey of 52,031 heterosexual men and women. Most men (66%) rated their penis as average, 22% as large, and 12% as small. Self-reported penis size was correlated positively with height and negatively with body fat level. Whereas 85% of women were satisfied with their partner's penis size, only 55% of men were satisfied with their penis size, 45% wanted to be larger, and 0.2% wanted to be smaller. Satisfaction did not vary across age groups from 18 to 65. Men reporting a larger-than-average penis rated their appearance most favorably, suggesting a possible confidence effect of perceived large penis size.

The crystal structures of the human androgen receptor (hAR) and human progesterone receptor ligand-binding domains in complex with the same ligand metribolone (R1881) have been determined. Both three-dimensional structures show the typical nuclear receptor fold. The change of two residues in the ligand-binding pocket between the human progesterone receptor and hAR is most likely the source for the specificity of R1881 to the hAR. The structural implications of the 14 known mutations in the ligand-binding pocket of the hAR ligand-binding domains associated with either prostate cancer or the partial or complete androgen receptor insensitivity syndrome were analyzed. The effects of most of these mutants could be explained on the basis of the crystal structure.

Larger penis size has been equated with a symbol of power, stamina, masculinity, and social status. Yet, there has been little research among men who have sex with men assessing the association between penis size and social-sexual health. Survey data from a diverse sample of 1,065 men who have sex with men were used to explore the association between perceived penis size and a variety of psychosocial outcomes. Seven percent of men felt their penis was "below average," 53.9% "average," and 35.5% "above average." Penis size was positively related to satisfaction with size and inversely related to lying about penis size (all ps < .01). Size was unrelated to condom use, frequency of sex partners, HIV status, or recent diagnoses of HBV, HCV, gonorrhea/Chlamydia/urinary tract infections, and syphilis. Men with above average penises were more likely to report HPV and HSV-2 (Fisher's exact p <or= .05). Men with below average penises were significantly more likely to identify as "bottoms" (anal receptive) and men with above average penises were significantly more likely to identify as "tops" (anal insertive). Finally, men with below average penises fared significantly worse than other men on three measures of psychosocial adjustment. Though most men felt their penis size was average, many fell outside this "norm." The disproportionate number of viral skin-to-skin STIs (HSV-2 and HPV) suggest size may play a role in condom slippage/breakage. Further, size played a significant role in sexual positioning and psychosocial adjustment. These data highlight the need to better understand the real individual-level consequences of living in a penis-centered society.

Men and women living in New Zealand and California completed five studies regarding human physique and sexual attractiveness. In Studies 1-3, women rated images of male stimuli and, in Studies 4-5, men rated female stimuli. In Study 1, women in both countries rated mesomorphic (muscular) and average male somatotypes as most attractive, followed by ectomorphic (slim) and endomorphic (heavily built) figures. In Study 2, amount and distribution of masculine trunk hair (chest and abdominal) was altered progressively in a series of front-posed male figures. In both countries, the image lacking any trunk hair was rated as the most attractive, with a steady decline in attractiveness as hirsutism became more pronounced. Study 3 assessed attractiveness of front-posed male figures that varied only in the length of the non-erect penis. Five lengths were presented: The smallest penile size was rated as less attractive than three intermediate sizes. The largest penile size was not the most attractive, but received higher scores than the unaltered and smallest penile size. In Study 4, men rated the attractiveness of back-posed female images varying in waist-to-hip ratio (WHR) (from 0.5 to 1.0). The 0.7 WHR figure was rated more attractive in New Zealand and the 0.6 WHR in California. Study 5 measured the attractiveness of female skin color; men expressed preferences for lighter skinned female figures in New Zealand and California. Results indicate very similar preferences for sexually dimorphic physical traits among men and women of European extraction, living in two culturally and geographically different environments.

Purpose: We provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation. Materials and methods: We prospectively measured flaccid and erect penile dimensions in 80 physically normal men before and after pharmacological erection. Results: Mean flaccid length was 8.8 cm., stretched length 12.4 cm. and erect length 12.9 cm. Neither patient age nor size of the flaccid penis accurately predicted erectile length. Stretched length most closely correlated with erect length. Conclusions: Only men with a flaccid length of less than 4 cm., or a stretched or erect length of less than 7.5 cm. should be considered candidates for penile lengthening.

Thus far the study of men's body image has been largely restricted to the dimensions of adiposity and muscularity. The aim of this study was to investigate in a systematic way multiple aspects of men's body images, in particular, head hair, body hair, height and penis size, in addition to body weight and muscularity. Questionnaires were completed online by 200 heterosexual men. It was found that men were dissatisfied with all six aspects of their bodies, and worried primarily about body weight, penis size and height. In addition, aspects of weight, muscularity, height and penis size, but not head or body hair, were related to overall appearance self-esteem. It was concluded that men's body image is both multi-faceted and complex.

Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high. In our opinion, until new, reliable, and more objective and reproducible data are available, these procedures should be regarded as investigational and patients should be discouraged from undergoing these invasive treatments.

Penile length and circumference were measured in twenty boys with isolated gonadotrophin deficiency, before and during the administration of androgen therapy. Their age ranged between 3 and 20 years. Considering as normal, measurements above the tenth centile, in all the patients but four the penile length was below normal, and in two it was borderline. Penis circumference was normal in two, borderline in four and subnormal in sixteen. Regular administration of androgen therapy increased penile length in eleven out of fourteen patients with achievement of normal length in four. It is concluded that congenital lack of LH and testicular androgen activation causes small sized penises, even in the prepubertal period. Gonadotrophin deficiency should be looked for in patients with measurements below the tenth centile. Early diagnosis and institution of androgen therapy between 11 and 12 years is likely to increase penile size and prevent the psychological side effects of undersized genitals and delayed puberty.
