Does testicular size affect sexual function? Scientific analysis of why testicles are different in size

Does testicular size affect sexual function? The testicles are the place where male friends produce sperm, belonging to the internal reproductive organs. Many friends have the misconception that the larger the testicles, the stronger their sexual ability. Does testicular size affect sexual function?

Men are very concerned about sexual ability, which is fate's will. Experts say that by focusing on the health of healthy testicles, one can maintain good sexual performance. But is the size of the testicles related to the strength of sexual ability? The following describes the relationship between testicles and sexual ability.

What is a normal testicle like

The testicles belong to the male reproductive organs. A normal male has two testicles, located on the left and right sides of the scrotum. The testicles are ovoid and gray white in color. Generally, the left side is about 1 centimeter lower than the right side. Some people have one large and one small testicle, one high and one low testicle. If the difference is not significant, it is normal.

There are numerous curved seminiferous tubules in the testicles, which contain interstitial cells. The seminiferous tubule is the place where sperm is produced. A person produces an astonishing number of sperm in their lifetime, with 3-4 milliliters of sperm per ejaculation containing 300 to 400 million sperm, or as little as 100 to 200 million; The number of sperm produced in a lifetime can reach over 1 trillion. The production of sperm is easily affected by various factors such as temperature. If the temperature around the testicles is too high or affected by chemical toxins, there will be obstacles to sperm production.

The larger the testicles, the better their sexual ability

Men all know that the testicles can produce sperm and secrete male hormones, maintaining male sexual characteristics and function. They are important reproductive organs for men. Therefore, if the testicles are larger, they will definitely secrete more male hormones, which means their sexual ability is stronger?

Male sexual ability is influenced by levels of sex hormones, but the misconception is that 'if the testicles are larger, they will definitely secrete more male hormones, resulting in stronger sexual ability.' This is because the size of the testicles is not absolutely proportional to the level of male hormones. Adult male testes are 3.5 to 4.5 centimeters long, 2 to 3 centimeters wide, and 1 to 2 centimeters thick. Each testicle weighs 10 to 15 grams, and testicles that do not differ significantly in size are considered normal. Under normal physiological conditions, the feedback effect of the gonadal axis (i.e. hypothalamus pituitary gonad) can regulate the levels of sex hormones in the human body. When male hormones are too high, it will inhibit the secretion of luteinizing hormone by the pituitary gland, keeping male hormones in a balanced state, achieving the goal of maintaining hormone balance in the body. So regardless of whether the testicles are larger or smaller, the human body will self regulate to keep male hormones at appropriate levels, neither too much nor too little.

The size of the testicles cannot be used solely to evaluate sexual ability. Male sexual function is also related to factors such as age, physical condition, health status, and mental state. If one randomly guesses one's sexual ability due to incorrect sexual knowledge, it will cause heavy psychological pressure, and over time, it will cause men to lose confidence, thereby affecting the quality of life for couples.

The testicles produce sperm and provide male hormones for men, enabling them to become true men. However, once the testicles "get sick", the consequences can be serious.

If the testicles shrink due to diseases, or become swollen due to infection, inflammation, or the appearance of tumors, it will affect the secretion of male hormones, thereby affecting male sexual function; Trauma can cause testicular bleeding and hematoma, leading to testicular bleeding disorders, as well as affecting testicular spermatogenic function and male hormone secretion; If the "size" of the testicles is much smaller than the normal value, it indicates abnormal testicular development. When a boy reaches the age of 10, if the testicles are still very small, it will cause insufficient secretion of male hormones, which will negatively affect the growth and development of the penis, leading to a short and small penis in adulthood, and damage to reproductive function, affecting sexual and reproductive function; If a boy suffers from cryptorchidism, where one or both testicles do not descend into the scrotum and remain in any part of the descent path, and cannot receive effective treatment before the age of 2, the spermatogenic function of the testicles will be severely damaged, easily leading to infertility and even cancer, with very serious consequences.

Does testicular size affect fertility

For most people, the focus on the genitalia is mainly on the issue of penis size, and few people place as much importance on testicular size. The male friends who are most concerned about testicular size in clinical practice are only those who have not been able to have children for many years after marriage. Due to being informed of male infertility, many men ask whether their testicles are fully developed. In order to make more male friends or normal people understand this common sense, the following are several commonly used detection methods to introduce.

Measuring testicular size with a caliper

This method is not limited by conditions, and the results are more accurate, but it takes more time. When measuring, use a caliper to measure the length, width, and thickness of the testicles, and then calculate the volume of the testicles according to the formula.

Testicular volume (ml)=length diameter (cm) × Width diameter (cm) × Thickness diameter (cm) ×Л/ According to reports, the testicular volume of adult men in China (measured by caliper) is: (13.1 ± 3.6) ml on the left side and (13.6 ± 4.2) ml on the right side at the age of 19-23, (13.6 ± 4.2) ml on the left side and (14.4 ± 4.5) ml on the right side at the age of 24-45. The above is for reference only.

Testicular model comparison method

Also known as the measurer comparison method. According to the pre calculated volume, oval shaped hard objects with different volumes and testicular shapes are made, labeled as 1-25 according to size. During measurement, the testicles are pulled up, the scrotal skin is tightened, and the measuring devices (i.e. testicular models, which can be purchased in the medical machinery market) are compared one by one next to the testicles. The measuring device volume that is similar in size to the testicles can be considered as the testicular volume.

Less commonly used drainage measurement methods

This is an earlier method used. When measuring, pull down the tested testicles, take warm water (around 25 ℃) and place it in a graduated container, so that the pulled down testicles are completely submerged in the water. The milliliter increase in water volume after immersion of the testicles is used as the volume of the testicles. Due to inconvenient clinical use, this method is now less commonly used.

Testicular size measurement is for reference only

Although various methods for measuring testicular size are provided, testicular size is only used as a reference. Because there is a significant difference in testicular volume between normal men, and there are also certain differences in testicular volumes on both sides of the same individual, the measured results can only be used as a reference. The judgment of testicular development and fertility should be combined with other examination results, and a comprehensive analysis should be conducted to draw a conclusion.

Testicular size does not affect sexual quality of life

Generally speaking, as long as the testicle size is within the normal range and its endocrine function is normal, it will not affect sexual activity. If you feel that the quality of sexual life is not good, or if you want to improve it, don't overly focus on the size of the testicles. Instead, look for other reasons.

How to improve the quality of sexual life

There are many methods. Overall, it means changing the time, location, environment, use of tools, and so on for sex. In terms of time, it can be changed from evening to morning; The location can also be from bed to chair, sofa, bathroom, kitchen, etc; Changing the environment for sex can be achieved by redecorating the bedroom, adjusting indoor lighting, etc; With the help of work, it is simpler. Using professional sex toys can enhance the fun of sexual life and make it more harmonious.

The size of the testicles is not related to sexual ability. However, when testicular problems occur, it is important to seek medical attention in a timely manner to avoid delaying treatment. By paying attention to male health issues, we can promptly identify and solve them.
