What are the causes of testicular sagging?

The testicles are important male reproductive organs that can effectively produce sperm. However, the testicles are also prone to various diseases. In daily life, many men find that their testicles are sagging and are very worried, fearing that they have some serious disease. So, what are the reasons for testicular sagging? Let's take a detailed look below.

In physiological terms, the scrotum is also a male's external genitalia, located on the body surface, below the penis. It is a soft and resilient bag-shaped sac composed of skin and muscle, like two hammocks hanging in the woods, holding the testicles and epididymis. There is a scrotal septum inside the scrotum, which divides the scrotal cavity into two parts, each containing a testicle and epididymis.

In fact, in addition to serving as an external barrier to protect the testicles, the scrotum also has a unique temperature-regulating function from a reproductive perspective, protecting the testicles inside at a suitable temperature (generally 1-2°C lower than the temperature in the abdominal cavity) to produce sperm. If you observe carefully, you will find that when in a cold environment, the scrotal skin will shrink and thicken, causing the scrotum to be pulled up and tense, and the surface area will shrink. At this time, the temperature of the testicles in the scrotum will not drop. On the contrary, in a higher temperature environment, the scrotal skin will relax and atrophy, causing the scrotum to sag and the surface area to increase. This is conducive to dissipating body temperature, preventing the temperature in the scrotum from rising, and protecting the testicles from producing sperm in a normal and suitable temperature environment. Therefore, the contraction and relaxation of the scrotum is a normal physiological regulation phenomenon.

Therefore, the temperature in the scrotum is basically around 35℃, so that organs such as the testicles can maintain normal functions. This is true for all men with normal development. Many people, because they do not understand this principle, often see their scrotum shrinking and relaxing and misunderstand it. This is common among patients who come to the clinic. For example, some men mistakenly believe that the shrinking and shrinking of the scrotum means that the testicles have become smaller, or even mistakenly believe that it is maldevelopment and they are afraid of infertility. In fact, this situation is just an illusion caused by the scrotum lifting and contracting, which makes the testicles rise close to the groin area and difficult to reach. Some people also mistakenly believe that the sagging of the scrotum is a manifestation of weakened sexual ability, and they are worried, which is even more nonsense.

The above is an introduction to the causes of testicular sagging, which I hope will help you understand. The testicles will show different shapes at different times or temperatures, which means that sagging is normal and there is no need to worry. If you are worried, you can go to a regular andrology hospital for diagnosis.
