One testicle might be a little lower than the other. Generally, you’ll have one testicle to the right and one testicle to the left of your penis. They’re enclosed in a pouch of skin called the scrotum. Another riveting piece of research from Harvard Medical School examined testosterone disruption due to chronic injuries. They discovered that cortisol spikes directly correlate to plummeting testosterone levels, particularly in aging individuals. The long-term consequences can be dire and multifaceted, affecting not only physical health but also mental well-being. Rarely, they may need to remove a damaged testicle (orchiectomy). If they don’t see anything wrong in the ultrasound, you probably don’t have a serious injury. Some injuries may lead to short-term issues with sexual performance. Most likely, you’ll be able to use simple treatments for a bruised testicle. Most people with testicular bruising do recover. If there’s any question about the severity of your injury, go to your nearest emergency department. See your provider if things get worse or you aren’t better in 48 hours. You should rest for 24 to 48 hours if you have a mild injury. Another medical option is the use of Human Chorionic Gonadotropin (HCG) injections, which stimulate the testes to produce more testosterone naturally. When addressing testosterone deficiencies post-trauma, medical interventions are often necessary to restore balance. In sum, these real-life case studies and recent research highlight just how vital it is to understand the intricate dance between physical trauma and testosterone. Under the tunica albuginea, the testes contain very fine-coiled tubes called seminiferous tubules. The testes are covered by a tough fibrous shell called the tunica albuginea. Normal volume is 15 to 25 cm3; the average is 18 cm3 per testis (range 12–30 cm3). An average adult testicle measures up to 5 cm × 2 cm × 3 cm (2 in × 3⁄4 in × 1+1⁄4 in). The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids (an orchidometer) of known sizes. Five months after the injury, spermiogram showed the onset of a cryptozoospermia and ultrasound revealed a left testicular volume decrease from 10 ml to 7 ml with an inhomogeneous, hypovascular area and the right emiscrotum completely uninhabited. A 31-year-old male presented to the emergency department with acute scrotum after a motorbike accident resulting in a severe blunt trauma against the motorbike's fuel tank. Testicular trauma is a frequent acquired cause of infertility; being accidents, work injuries and sport activities that are the most common causes of testicular traumas.1,2 Strangely, the issue of management of serious testicular trauma and fertility preservation has not been studied extensively before, existing only sporadic reports in international literature. If you have signs and symptoms of low testosterone, a healthcare provider will give you a physical exam. Most males with symptoms of low testosterone don’t have a problem with their pituitary glands or testicles. Those low levels cause decreased testosterone and sperm production. As a result, your testicles make too little or no testosterone and sperm.
