As of 2022, the number of infertile patients in China has exceeded 40 million, from 1% to 3% of the population of childbearing age 30 years ago to 12.5% today. Over the past 30 years, the number has increased by more than 10 times, with the majority of infertile patients aged 25 to 37 showing a rapid growth trend. Many people are ashamed to mention their private parts, and even if they feel unwell, they avoid taking medicine and avoiding medical treatment. In fact, to determine whether one's testicular spermatogenic function is normal, one only needs to undergo a check-up at the hospital's urology department. The editor of 592 Baobao Net suggests that male friends undergo 1-2 physical examinations every year, with a focus on reproductive system health.

Three types of testicular abnormalities

1. Abnormal testicular position: Syndidymosis refers to bilateral testicular fusion, or mistaken for cryptorchidism or monorchidism, usually accompanied by other serious congenital malformations. Patients who develop into adulthood have few friends. In contrast, cryptorchidism has a higher incidence rate. Cryptorchidism refers to the testicles staying in any abnormal position during descent, such as the waist, abdomen, groin, or other parts. As long as surgery is performed, the cryptorchidism will have good therapeutic effects.

2. Abnormal testicular size: Abnormal testicular size, that is, abnormal congenital testicular development, testicular atrophy, etc. Torsion of the spermatic cord during the fetal period due to blood supply disorders or testicular decline may lead to testicular dysplasia. In cases of sexual immaturity and pituitary dysfunction, testicular dysplasia may also occur.

3. Abnormal number of testes: Polydidymosis refers to two or more testes, usually no more than three, with more left and more right testes, which is very rare. Excessive testicles rarely develop normally, and prolonged ectopic pregnancy can lead to atrophy and malignant transformation. Men do not have testicles, and the situation is relatively rare. Unilateral absence of testicles is more common, usually accompanied by contralateral cryptorchidism.

The size of the testicles on both sides of each male is not exactly the same. But the size difference between the two testicles is not significant. According to statistics, the right testicle is slightly larger than the left. Calculated by the length, width, and thickness of the testicles, the average length of the left testicle is 3.38cmX2.37cmX, and the average length of the left testicle is 3.30cmX2.27cmX1.71cm. Even within the same age group, there are significant differences in testicular size. But when the volume of adult male testicles exceeds 15ml, their function is basically normal.

If the testicles on both sides were basically the same size in the past, but suddenly one side of the testicles has significantly increased in the near future, it is necessary to go to the hospital for examination in a timely manner. If unilateral testicular enlargement occurs, symptoms such as fever and local pain may also occur, which should be considered as epididymitis or orchitis. If testicular enlargement is not accompanied by any symptoms, the possibility of testicular tumors should be considered, and timely examination is necessary to avoid negligence.

For normal individuals, some people have different sizes on both sides of their testicles, sometimes with significant differences, mainly due to congenital diseases. If one side of the testicles is congenital and underdeveloped, its manifestation is that one side of the testicles is very small and soft, such as in childhood, while the other side of the testicles can have a compensatory effect, which is slightly larger than normal, so the size of the two testicles may vary, but this situation is not common. In addition, trauma can also cause differences in the size of the testicles on both sides, resulting in bleeding and hematoma within the testicles, resulting in impaired blood supply to the testicles and testicular atrophy. Therefore, the affected side is smaller than the opposite side. The virus damages the seminiferous tubules of the testes, causing atrophy on one side of the testes.
