IQ and Micropenis

Today we will have a quick look over an old study published in 1980, named "Psychology of syndromes. IQ and micropenis." As indicated by the paper's name, the authors wanted to see whether there is a correlation between micropenis and an abnormal intelligence score (IQ).

The authors examined 20 patients, all presenting with a micropenis. According to the abstract, the IQs ranged from 81 to 137, with the median IQ being 116. The majority of patients (75 %) had an IQ score of 109 or more. The authors conclude that people with a micropenis in regards to intelligence are pretty much normal..

Here is the study's abstract:
"In 20 patients with a micropenis, IQs ranged from 81 to 137, with a mean of 117 +/- 14 and a median of 116. The distribution of IQs approximated a normal distribution except that the entire curve was skewed, with the majority (75%) of scores higher than 109. There was no clustering related to diagnosis, age, sex of rearing, or serial testing to account for the skew, which was stronger for verbal than for performance IQ. These findings negated the probability of an adverse intellectual prognosis for patients born with a micropenis."

IQ Definition 
For anyone not familiar with the term, IQ (short for intelligence quotient) is a score derived from one of several standardized tests designed to assess intelligence. The abbreviation "IQ" comes from the German term Intelligenz-Quotient, originally coined by psychologist William Stern.
