Cryptorchidism is a condition in which a male infant is born with unilateral or bilateral testes that do not descend from the abdominal cavity to the scrotum but remain at any point in their normal descent. The incidence is relatively high in premature infants, both unilaterally and bilaterally. As a male urologist, when many relatives, friends and fellow students have children, as long as they are boys, when I go to see them, I cover my hands first: come, let uncle touch the eggs. after 1 year old, there are few chances for cryptorchidism to descend on its own, and most of them need surgical treatment. If cryptorchidism is not treated in time, it will affect the reproductive function in adulthood, and the ideal age for preserving fertility is 1-2 years old; if surgery is performed after 2 years old, the ability of testosterone secretion of testes can still be preserved, but the sperm production ability is damaged. Cryptorchidism has an increased chance of malignant transformation and is susceptible to trauma and testicular torsion. The incidence of testicular cancer in normal people is 1-2/100,000, but the chance of testicular cancer in cryptorchidism is 40 times greater than normal. The famous Chinese star Bruce Lee is cryptorchidism. The famous Tour de France cyclist Armstrong got testicular cancer. Other risk factors for testicular cancer include genetics, infertility and tallness. Therefore, if someone else in the family has testicular cancer, it is important for other men in the family to take it seriously. Testicular cancer is most common in young people, and the young people reading this Weibo article are mostly of high incidence age. The most common symptom is that the testicles are slowly swelling without pain, and they are still hard to touch and heavy to weigh, just like the feeling of having sand in your pocket. A year ago, the respiratory department requested a consultation, the boy was less than 20 years old, the mother and son are dependent on each other, because the fever to stay in the respiratory department, a check of multiple metastases in the lungs, resulting in obstructive pneumonia before coming to the clinic. The desperate look in the mother’s eyes still remains in my memory. Many testicular cancers are prone to early metastasis and early detection is important. Most tumors can be cured with early detection and active treatment. Two days ago, a young man came to the clinic for a review, a patient I had treated before, also with testicular cancer, three years after surgery. The country has liberalized the second child, and he also wanted to have a semen test. Once I checked, the only remaining testicle on the other side was still functioning well and the semen was completely normal, so I guess I was able to eat his wedding candy. After a testicular tumor removes one testicle, most of the other testicle can also produce sufficient amount of testosterone to meet the needs of a man’s body and can also handle a woman. Depending on the type of pathology, testicular cancer may also need to be combined with radiotherapy or chemotherapy. It is also possible to store semen for backup before radiotherapy or chemotherapy, so that even if the testicles are damaged by radiotherapy or chemotherapy, you can still be prepared. Some men may ask, after the removal of testicles, the scrotum is empty, how embarrassing in the future. This is not a small problem, women can put a prosthesis in the breast, doctors can also put a testicular prosthesis in the scrotum to achieve the purpose of faking. Some women may question, you doctors are not helping men cheat us women? You ask, we do have a little vain, but on second thought, you have repaired the hymen, breast augmentation, double eyelids …… is still less? The actual fact is that you will be able to get a lot more than just a few of the most popular and most popular of the best. Recently admitted a patient. He, who has a family and a job; he has children; he, who had a left cryptorchid retraction surgery at the age of 5; he, who is now found to have a left testicular tumor. He, further examination found multiple metastases in pelvis, abdomen and lung; he, only 30 years old …… cryptorchid is prone to malignant transformation. If he had timely and regular review after the implantation surgery, touching himself diligently and coming to the clinic in time if he found any abnormality, he would not have such a tragic ending. Then the question arises, how to check the testicles? It is best to check in the shower. Warm water can stretch the folds of the scrotum, which is conducive to the detection of lesions. To do this, place your thumb on the top of the testicle and your index and middle fingers on the bottom, gently turn and knead the testicle, and carefully observe to feel for any lumps or abnormal hardness. Repeat this process to check the other testicle. A normal testicle should be smooth to the touch, without lumps, full but not hard, and without pain. If you find a hard pea-sized lump on the surface of the testicle or if the testicle is swollen and enlarged, seek medical attention promptly so that you can avoid a chicken-and-egg situation.
