It is possible for the penis to become larger later in life. In children before puberty, medication may be used. In adulthood, the size of the penis usually does not continue to grow and develop and cannot be made larger later in life.
For those with a short penis, treatment in early childhood usually begins at 6 months to 1 year of age. For those with abnormal gonadal function, such as simple testicular hypoplasia and insufficient testosterone production, topical testosterone cream or intramuscular testosterone injections may be used and followed up for observation until 6 years of age. For those who do not respond to testosterone therapy, HCG or long-acting testosterone is used according to the results of the hormone measurements mentioned above. The penis may grow after treatment.
If the penis is still short after puberty, plastic surgery may be considered if necessary. The main surgical method is penile lengthening. If the penis is too small, the patient may also consider penile reshaping and placement of a penile prosthesis. Surgery carries certain risks or may not meet psychological expectations, and should be chosen carefully with full knowledge of the pros and cons of surgery.
In terms of fertility, there is no direct relationship between penis size and fertility. If there is any concern in this regard, the patient should consult a doctor, who will provide a reasonable explanation and solution in terms of erectile function and sperm activity.
