I found this study interesting.
Here is something to look
forward to from the study:
“ Statistical analysis showed that penile length is increased in older age ”
This was also informative:
“ Measurement of penile length can be made during flaccid, stretched and erect states. The present study measured penile length in the flaccid and stretch states only. The erect penile length was not measured because of ethical and religious belief barriers. This limitation is not expected to infringe the benefits of the present study measurements. Other studies have suggested that measurements of FPL and SPL provided a reliable indicator of erect size. The regression equation in the Wessells et al. [11] study showed that SPL is a good predictor for erect penile length (R2 = 0.793)”
Talking About Flaccid Length!Reference range of flaccid and stretched penile lengths of adult males in Baghdad:
A cross-sectional study. (2017)
Abbreviations: FPL, flaccid penile length; SPL, stretched penile length.Subjects and methods
Over a 1-year period, FPL and SPL measurements were taken from males undergoing medical examination in the outpatient clinic of the Al-Karama Teaching Hospital, using a rigid centimetre ruler. The correlation between penile length and age was investigated.The age of the subjects was categorised into 10-year intervals as shown in Table 1, where the mean FPL and SPL ranged between as small as 9 and 11.8 cm in the age group 30–39 years to as high as 11.4 and 14.1 cm (5.5") for those aged 60–77 years.
