An age-, body mass index (BMI)-, and follow-up duration-matched cohort of men with a nonprolactin-secreting pituitary lesion and repeatedly normal testosterone levels (PA-nt) was used as main comparator to assess testosterone and clinical symptoms changes over a follow-up of the same duration. In addition, approximately 60% to 70% of hypogonadal patients with PSPA are reported to recover their testosterone levels after a successful (ie, prolactin-normalizing) treatment . The most common cause of gigantism is a benign (noncancerous) tumor on your child’s pituitary gland (a pituitary adenoma) that releases excess growth hormone (GH). Testosterone therapy is approved for the treatment of delayed male puberty and abnormally low production of testosterone secondary to malfunction of the testes, pituitary or hypothalamus. These tests assess for under or over-production of pituitary hormones and are essential in diagnosing pituitary gland failure which may involve one or multiple hormones such as low testosterone or low thyroid levels. Medical TreatmentIn general, medical treatment of gonadotropin pituitary adenoma was minimally effective with respect to reduction of tumor size, but its effect on lowering testosterone levels was variable. In boys, this can lead to developing breasts (i.e. gynecomastia), absence of pubic hair, and delayed growth of the penis.

The authors declare no conflicts of interest in relation to this manuscript. However, robust immunoassays are nowadays reported to be also highly reliable and provide good accuracy, especially when dealing with values within the normal range, as those reported here . In this study, we found that tumor invasiveness could prevent the improvement of the HPG axis in patients after surgery, similar to some previous findings. Therefore, we suggest that the poor pituitary function prognosis in CNPA patients may be related to irreversible pituitary damage caused by pathological changes such as compression and ischemic necrosis. CNPA generally has a slower onset and a longer time to compress the pituitary gland, so the recovery time of anterior pituitary function is also longer30,31. Our study showed that the size of pituitary adenomas was a predictor of HPG axis recovery in patients after surgery, which is consistent with other reports in the literature11,27. Nomikos et al. screened 463 patients who underwent conventional trans-sphenoidal surgery for preoperative hypogonadism, and only 74 (15.9%) patients recovered gonadal function 3 months after surgery. Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. The brain is also affected by this sexual differentiation; the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. Some of these effects may decline as testosterone levels might decrease in the later decades of adult life. In some cases, ESS may cause certain symptoms, including hormone imbalances, frequent headaches and vision changes. It’s often caused by a functioning/secreting pituitary adenoma (a noncancerous tumor). A deficiency in two or more of the pituitary hormones is called panhypopituitarism. Some pituitary adenomas release excess pituitary hormones. A pituitary adenoma is a benign (noncancerous) growth on your pituitary gland. Several conditions can affect or are affected by your pituitary gland’s function. Seventy-one (55.9%) patients recovered testosterone levels without developing new hypopituitarism after surgical resection of the tumor via pseudocapsule. According to the postoperative testosterone classification criteria, 127 of 291 (43.6%) patients had low preoperative testosterone, in which testosterone levels returned to the normal range at 3-month postoperative follow-up in 71 (55.9%). The diagnostic criteria for patients with central hypogonadism are low testosterone levels, accompanied by inappropriate normal or low gonadotropin levels. In clinical practice, as an indicator for efficacy determination, changes in prolactin (PRL), cortisol, growth hormone, and thyroid hormone often gain more attention, and testosterone is relatively less assessed. Seventy-one of 127 patients with low preoperative testosterone levels recovered to normal levels. In conclusion, pituitary gland disorders can have a significant impact on testosterone levels and overall men’s health. The pituitary gland acts as the master gland, controlling the production and release of various hormones, including testosterone.
