A history of previous surgery on the pituitary (hyperprolactinemia) or thyroid gland (hyperthyroidism with increased binding globulin, resulting in a decrease in free testosterone levels), excess endogenous (Cushing syndrome) or exogenous (hypergonadism) steroid exposure, obesity (which causes a decrease in free testosterone levels), and various chronic diseases (AIDS, malnutrition) may also indicate or suggest endocrinopathy. While logic dictates that treating this underlying endocrinopathy should reverse the ED, there is a lack of clinical evidence to support this expectation; ie, not all patients with ED and a low testosterone level have an improvement in erectile function when treated with exogenous androgen. Although erectile function is clearly androgen dependent, is it just as clear at what level of testosterone erectile dysfunction (ED) begins? Selective serotonin reuptake inhibitors (SSRIs) have sexual side effects that are difficult to be tolerated by patients.6 In this case report, we aimed to describe an adolescent with ADHD who developed spontaneous ejaculation during atomoxetine treatment. Drug treatment may affect these brain structures, neurotransmitters and hormones and cause sexual dysfunction. That’s why random boners can occur in the middle of a meeting or during a workout. As you age, these may become less frequent, but they remain a sign that your body is functioning as it should. Testosterone peaks in the early morning, and your brain reduces inhibitory signals while you dream. They happen during REM sleep and can occur 3 to 5 times a night. The 400-mg doses, while obtaining higher peak values, will not maintain eugonadal levels beyond the 3-week limit. In the United States, the 17β-hydroxyl esters of testosterone include the short-acting testosterone propionate and longer-acting testosterones enanthate and cypionate. Parenteral preparations of testosterone are usually administered in an oil-based vehicle, such as cottonseed or sesame oil. These 17β hydroxyl esters lack inherent androgenic activity and must be hydrolyzed to testosterone before they become active. Intramuscular testosterone can be administered in its aqueous, unmodified form; however, its rapid absorption and degradation make this form unsatisfactory for testosterone replacement. These 17α alkylated testosterones may be administered either orally or buccally but, because of their high cost, minimal potency, and risk of hepatotoxicity, these types of oral androgens should not be used clinically for androgen replacement. The most effective of oral agents of testosterone are the 17α alkylated testosterones, such as methyltestosterone. That’s why spontaneous boners often happen in public or inconvenient situations. It’s like a self-check system—especially when you’re not sexually active. It’s not about desire—it’s a misfire in the electrical system. It’s why spontaneous boners are so common in teenagers and young adults with high dopamine sensitivity. These small cues can trigger an erection faster than you realize—especially if you’re already primed hormonally. These erections are due to the body’s automatism and only come from the body’s automatism, not from sexual images or desire. Surprising as they may be, they are completely normal and indicative of healthy reproductive action in process. Interestingly, the presence of morning wood is not only related to testosterone but also serves as a marker for vascular and neurological health.
