Patient's question:
Six months ago, I went to a urology hospital for a check-up, and now I regret it deeply. My penis is usually 4 cm long when flaccid, but when erect, it's a bit over 10 cm, yet it was diagnosed as micropenis. During the examination, they used intracavernous injection of prostaglandin E1 12ug to measure the erection length. After the injection, it took 2-4 hours for my penis to gradually return to a flaccid state.Doctor's answer:
is a smooth muscle relaxant that can dilate arteries and increase blood flow to the penis. The relaxation of smooth muscles and the dilation of arteries can both fill the cavernous sinus of the penis with blood, thereby restricting blood flow. Regardless of whether sexual stimulation is present, this will induce penile erection. During your examination, you were administered 12ug of via intracavernous injection, and the length of your penile erection was measured. It primarily binds to plasma proteins. It is metabolized rapidly in the blood, and its metabolites are mainly excreted through the kidneys. Approximately 90% of the drug is excreted in the urine within 24 hours after administration, with the remainder excreted through the feces. Since you only used it once, there should be no long-term side effects.Medical Advice:
Your penis is 4 cm long in its normal state and measures over 10 cm when erect, which does not qualify as micropenis. The standard for normal adult male penises in China is as follows:
- In the normal state, the longest length is 14.5 cm, the shortest is 4 cm, and the average is 8.375 cm.
- The maximum circumference is 12 cm, the minimum is 4.5 cm, and the average is 8.3 cm.
- When erect, the longest length is 16 cm, the shortest is 9 cm, and the average is 12 cm.
- The maximum circumference when erect is 14 cm, the minimum is 8 cm, and the average is 10.75 cm.
Your condition is considered normal and does not require treatment. In the future, it is advisable not to easily believe advertisements, as some private hospitals may exaggerate their claims for profit and engage in irregular medical practices. For any future medical examinations or treatments, it is recommended to visit a local reputable hospital. Wishing you good health!
