What Every Man Should Know About His Testicles, According to a Urologist

What every man should know about – Dr. Jamin Brahmbhatt, a urologist and robotic surgeon at Orlando Health, often encounters patients who have delayed addressing concerns about their testicles. A recent case highlights the importance of vigilance: a man arrived at his clinic with his girlfriend after feeling an unusual lump in his testicle for months. An ultrasound confirmed the diagnosis—benign cysts, not cancer. The patient, relieved, remarked, “See. I told you so. I’m fine.” Dr. Brahmbhatt, however, added a note of gratitude, encouraging the man to thank his girlfriend for prompting the visit. “This could have gone very differently,” he said, emphasizing the critical role of early detection.

The Dual Role of the Testicles

Testicles serve two primary functions in the male reproductive system. First, they produce sperm, a process that takes approximately three months. These microscopic cells are generated within the seminiferous tubules, intricate networks of small, coiled structures inside each testicle. Second, they secrete male sex hormones, predominantly testosterone, which is essential for maintaining muscle mass, bone density, libido, mood, and energy levels. Specialized Leydig cells, located within the testicular tissue, are responsible for synthesizing most of the body’s testosterone.

“Knowing your baseline allows you to detect any deviations more easily.”

While most testicular lumps are benign, some may indicate serious conditions, such as cancer. The only way to determine the nature of a lump is through a thorough examination. Delaying care can lead to missed opportunities for early intervention, potentially turning a minor issue into a life-threatening condition. During his medical school urology rotation, Dr. Brahmbhatt discovered a similar benign cyst in his own testicle. He described the experience as a mix of anxiety and realization, noting that he had never been aware of his “normal” anatomy until that moment.

Why Regular Self-Exams Matter

Dr. Brahmbhatt advocates for routine self-examinations as a simple yet effective tool for men’s health. He explains that there are no strict guidelines mandating monthly checks, but familiarizing oneself with the typical texture and size of testicles can help identify changes promptly. The exam itself is quick—taking less than two minutes—yet it can make a significant difference in catching potential problems early. “You don’t need to obsess,” he said, “but periodic checks, especially during a shower, can provide a reliable reference point.”

Men should also be aware that having one testicle does not compromise their ability to function. Whether due to injury, congenital conditions, or medical procedures, a single testicle can still support sperm production and hormone regulation. This is particularly relevant when considering the US government’s recent policies on testosterone therapy, which have sparked debates about the accessibility and effectiveness of treatments for hormonal imbalances. Understanding how testicles develop and operate can help men navigate these discussions with confidence.

The Development of the Testicles

During fetal development, testicles form in the abdomen near the kidneys. As a baby approaches full term, they descend through the inguinal canal—a muscular tunnel—into the scrotum. This movement is crucial for maintaining the optimal temperature required for sperm production. The scrotum acts as a temperature-regulated chamber, contracting when cold to bring the testicles closer to the body and relaxing when warm to allow them to hang lower. This dynamic adjustment explains why testicles appear differently in a cold pool compared to a hot shower.

The scrotum’s role extends beyond temperature control. It also provides physical protection for the testicles, which are vulnerable to injury. Injuries to the scrotum can cause pain that radiates up the abdomen, a common complaint among patients. Dr. Brahmbhatt notes that this pain often prompts men to seek medical attention, underscoring the scrotum’s importance in signaling potential issues.

The Anatomy of the Testicles

Each testicle is roughly the size of a small egg and has a smooth, firm texture. Behind the testicle lies the epididymis, a soft, wormlike structure where sperm mature before being transported through the vas deferens. This tube, which can be surgically severed during a vasectomy, connects the testicle to the ejaculatory ducts. The spermatic cord, a bundle of arteries, veins, nerves, and lymphatic vessels, runs from the top of the testicle and supports its function. Men can feel this cord’s structures as they rise from the testicle’s surface, a subtle but informative detail during self-examinations.

It’s also important to note that testicles are typically not symmetrical. The left testicle is often slightly lower than the right, and one may be larger than the other. These variations are normal and not a cause for concern. However, any sudden changes in size, shape, or texture should be evaluated by a healthcare professional. Dr. Brahmbhatt highlights that the process of checking for abnormalities is not about perfection but about awareness.

Vasectomies: A Common Procedure with Key Considerations

Vasectomies, a popular method of permanent contraception, involve cutting the vas deferens. This procedure is quick, minimally invasive, and highly effective. However, Dr. Brahmbhatt emphasizes that understanding the anatomy is crucial for both patients and physicians. The epididymis, often mistaken for a tumor, is a key structure adjacent to the testicle. Similarly, the spermatic cord plays a vital role in blood flow and nerve function. Patients considering a vasectomy should be informed about these structures and the procedure’s impact on sperm transport.

Despite their size, testicles are delicate organs that require attention to function optimally. From their developmental journey in the abdomen to their role in hormone production and sperm generation, they are central to male health. Men who neglect regular self-exams may miss subtle signs of conditions like testicular cancer, epididymitis, or hydroceles. Dr. Brahmbhatt stresses that these exams are not complicated—just a habit that can save lives. “Early detection is the key,” he said. “A few minutes of awareness can prevent a lot of unnecessary worry.”

In summary, the testicles are more than just a part of the male anatomy—they are critical to fertility, hormone balance, and overall well-being. By staying informed and proactive, men can better understand their bodies and respond to changes with confidence. Whether through self-exams, understanding their development, or recognizing the role of the spermatic cord, knowledge is power when it comes to testicular health.
