What is congenital malformation of the penis?

Men's health is often ignored by the public, but despite this, we can still see advertisements everywhere and learn about some male diseases on the bus. For example, prostatitis, congenital malformation of the penis, etc. So today I will introduce to you one of the most troublesome male diseases - congenital malformation of the penis. I think it will be helpful to everyone.

1. Testicular deformity

Abnormal quantity:

(1) No testis. Rare, probably due to incomplete testicular differentiation caused by some reasons during embryonic development, so the testis atrophies and degenerates. However, because some interstitial cells still exist, the patient may have male external genitalia and appearance. It should be distinguished from bilateral occult testis. The characteristic of this syndrome is the increase of luteinizing hormone (LH) in the blood. The plasma testosterone level does not increase after the administration of chorionic gonadotropin. Androgens should be given regularly after puberty. Otherwise, eunuch syndrome will occur. Testicular transplantation surgery can be performed, using sibling or allogeneic testis transplantation. This syndrome is often combined with the absence of vas deferens and epididymis.

(2) Single testicle. Most cases do not require special treatment. The purpose of surgical examination is to find cryptic testicles that may exist in the abdominal cavity to prevent cancer.

(3) Polytestis. Refers to the presence of 3 or more testicles. Abnormal size:

(4) Testicles that are smaller than normal due to incomplete development are usually not isolated symptoms.

(5) Testicular enlargement due to hyperplasia, such as testicular teratoma.

(6) Congenital atrophy. Abnormal position:

(7) Testicular fusion. This refers to the fusion of the two testicles into one in the abdominal cavity or scrotum. It can be easily mistaken for cryptorchidism or monotestis. It is often accompanied by renal malformations.

(8) Cryptorchidism

(9) Ectopic testicles.

(10) Abnormal attachment of the testicles and epididymis can cause spermatogenesis obstruction and lead to infertility. If the connection between the two is not good, testicular torsion can easily occur, and even tissue necrosis due to insufficient blood supply.

2. Vas deferens malformation

It can be divided into many situations, including congenital absence, communication with the ureter, and duplicated vas deferens.

If there is no other malformation and the vas deferens is simply absent, the patient's sexual desire and sexual function are normal, and the only symptom is infertility. The clinical manifestation is azoospermia, but the serum hormone levels are normal, which can be confirmed by testicular biopsy. If possible, surgical treatment can be performed to anastomose the vas deferens stump with the epididymis.

3. Penile abnormalities

It can be divided into size abnormalities and position abnormalities. It often appears together with other deformities.

(1) Complete absence of the penis. This is often accompanied by urethral malformations and is difficult to treat. In the past, penoplasty was not effective. It is best to remove the testicles and perform urethroplasty, and use estrogen to maintain female sexual characteristics after puberty.

(2) Latent penis. Due to its short development, it is covered by fat in the perineum, scrotum, pubis, etc. As the fat decreases during the development process, the penis is exposed. Plastic surgery can also be used to "liberate" the penis and restore it to normal.

(3) Congenital penile torsion. When the penis is twisted, the direction of the urethral opening changes. A small number of people may experience symptoms such as dull pain during erection. This condition is also prone to be combined with abnormal erection.

(4) Two penises. They can be arranged in parallel or in front and back.

(5) The penis is too large or too small. Rare. If it is too large, it can be shortened by plastic surgery. If it is too small, the cause is complex and needs to be treated appropriately.

(6) Phimosis. Phimosis can occur in more than 25% of boys, but it is significantly less common in adults than in adolescents. Phimosis can be divided into physiological phimosis, pseudophimosis (foreskin is too long), true phimosis and incarcerated phimosis.

If the foreskin is adhered to the glans penis, or there are transverse blood vessels in the foreskin, or the foreskin is severe and never turned up for cleaning, it may restrict the development of the glans penis and even cause hard lumps composed of smegma, urine sediment, bacteria, etc.

(7) Epispadias and hypospadias. The latter is more common, while the former is less common and can affect erectile function.

4. Congenital malformations of the prostate and seminal vesicles

(1) Prostatic hypoplasia is often associated with hypoplasia of other sexual organs. Prostatic cysts may be complicated by dysuria.

(2) Absence of the seminal vesicles and combined infertility can be preliminarily diagnosed by extremely low levels of fructose in seminal plasma and low semen volume, and can be confirmed by vas deferens and seminal vesiculography.

Congenital penile disease is a very difficult disease, so here I want to warn all men, do not feel inferior because of this disease, and dare not see a doctor. In fact, only when the problem is solved in time when it is discovered, can we rarely or even avoid the trouble of the disease.
