User avatar Hi,
Some degree of penile retraction or shrinkage during voiding is not unusual even in healthy individuals. Perhaps, the concentration becomes so focused on the act of voiding that a penis that were in an ever so minimally turgid condition, may shrink (attain a more flaccid state).

Both the anti-hypertensive medications that you are taking (metoprolol and amlodepine), are capable of causing erectile dysfunction as an adverse effect.

There is an interesting syndrome which is worth mentioning here in this context. Genital Retraction Syndrome, more commonly known as 'Koro', is a culture-specific syndrome. Koro is defined as the unique conviction that a protruding organ, such as the male genital(penis) or the female breast, is retracting into the body, with an intense anxiety that this might result in death and associated with behaviors aimed at preventing such retraction.

It has been seen to occur in two forms.
- the epidemic form, and
- the sporadic form.


East Asia is thought to be 'endemic' for this condition. Its roots would probably be traced to China. Epidemic situations had occurred in the past almost exclusively in East Asia (Singapore, China, and also India). Usually afflicts young males. Lower literacy, younger age and single marital status have been reported to be risk factors. It is a social malady perpetuated and maintained by cultural beliefs that affect the whole community and not just those afflicted by it.
Cheng, S. T. (1996) A critical review of Chineses Koro. Culture, Medicine & Psychiatry 20:1 , p. 67.

An increasing number of sporadic cases have been reported, more often in non-Asian cultures, in the context of a wide variety of systemic, neurologic, or psychiatric pathologies. These sporadic cases are referred to as 'Koro-like' and they have been described in patients with anxiety, panic attacks, psychosis, affective disorder, phobia, hypochondriasis, medications, HIV, and substance abuse, prostatectomies, STDs, infertility, strokes and brain tumors.

Also, as you had fractured your cervical spine in the recent past (2008), You need consult a neurologist for an expert assessment.
Best wishes!
