Shrinkage of the penis: Reasons, remedies, and occurrence factors
In a recent study, the average penis size was found to be 13.61 cm (5.36 inches) erect and 12.98 cm (5.11 inches) flaccid, pulled [1]. However, as men age, they may experience a decrease in penis size due to various factors. This article aims to shed light on the common causes of penis shrinkage, treatment options, and management strategies.
One of the primary reasons for penis shrinkage in older men is an age-related decline in testosterone levels. As testosterone decreases by about 1% per year after age 30, it may not directly reduce erection size but can make the penis feel smaller due to less rigidity [1][3]. Other factors contributing to penis shrinkage include poor blood flow and vascular health, erectile dysfunction, loss of tissue elasticity, and hormonal imbalances [3].
Smoking has been linked to below-average penis size and erectile dysfunction, although further controlled studies are necessary to investigate this potential link fully [2]. Atherosclerosis, or fatty deposits in the arteries, can also cause reduced blood flow to the penis, further contributing to penis shrinkage [2].
Treatment for penis shrinkage focuses on improving overall health, managing medical conditions, and in some cases, hormonal therapy under a doctor’s care [1][3][4]. Improving lifestyle factors, such as regular physical activity, good nutrition, managing stress, and maintaining a healthy weight, support blood flow and tissue health [3]. Addressing hormonal changes, managing underlying health conditions, and pelvic floor exercises can also help improve erectile function and penile health [1][4].
For men who experience penis shrinkage after prostate removal, the condition may improve on its own within a few months to a year [5]. Consistent use of phosphodiesterase 5 (PDE5) inhibitors after surgery can increase the percentage of regained penile length [6].
Peyronie's disease, which involves the development of fibrous scar tissue inside the penis, causing it to curve during erection, can lead to a reduction in the length and circumference of a penis [7]. Treatment for Peyronie's disease may involve removing scar tissue from inside the penis through medication, surgery, or ultrasound technology [8]. Repairing the curvature caused by Peyronie's disease can help improve sexual function and reduce pain, although penis shrinkage is irreversible [8].
It's important to note that sex and gender exist on spectrums, and this article refers to "male" and "female" in terms of sex assigned at birth. Men who experience concerns about penis shrinkage, pain, or other sexual problems should consult a healthcare provider for a thorough examination and discussion of individual treatment options [3].
Some medications, including anti-hypertensives and selective serotonin reuptake inhibitors, can reduce blood flow to the penis and affect sexual performance [9]. Similarly, finasteride and dutasteride, common anti-baldness medications, have been found to cause penile shrinkage and other sexual dysfunctions [10].
In conclusion, penis shrinkage in older men is primarily linked to hormonal decline, vascular health, and tissue changes with age. By adopting a healthy lifestyle, addressing hormonal imbalances, and managing underlying health conditions, men can help maintain and possibly even improve their penis health as they age.
