Further improvement in these symptoms may be seen after longer term use (9,29,32,67). Oral testosterone undecanoate, however, bypasses first-pass metabolism through its preferential absorption into the lymphatic system. The modified testosterone 17α-methyl testosterone, however, has delayed metabolism in the liver. The testosterone pellets are usually implanted under the skin of the lower abdomen using a trochar and cannula or are inserted into the gluteus muscle.
Men taking supplemental testosterone should be monitored periodically. A prostate biopsy may be needed if PSA elevation persists after TRT is stopped. Potential adverse effects of testosterone and its analogs include
Because of the increase in sex hormone–binding globulin (SHBG) with aging, total testosterone level is a less sensitive indicator of hypogonadism after age 50. Some syndromes of hypogonadism (eg, cryptorchidism, some systemic disorders) affect sperm production more than testosterone levels. When primary hypogonadism affects testosterone production, testosterone is insufficient to inhibit production of FSH and LH; hence, FSH and LH levels are elevated. It may result from a disorder of the testes (primary hypogonadism) or of the hypothalamic-pituitary axis (secondary hypogonadism). Endocrinologists diagnose the condition using hormone tests and imaging and treat it with testosterone therapy, lifestyle changes, and fertility-preserving methods. Treatment aims to bring testosterone back to normal levels, reduce symptoms, and improve overall quality of life.
It also can affect people with sickle-cell disease, thalassemia, or alcoholism. People undergoing glucocorticoid therapy can develop the condition. Mixed hypogonadism is more common with increased age. These parts of the brain control hormone production by the testes. Secondary hypogonadism is caused by damage to the pituitary gland or hypothalamus. Fatigue and mental fogginess are some commonly reported mental and emotional symptoms in men with low T. Later in life, insufficient testosterone can lead to other problems.
With such a high prevalence, hypogonadism is a candidate for the most common complication of male type 2 diabetes. However, clinicians have often not related low testosterone concentrations to clinical hypogonadism. Low testosterone concentrations are known to occur in association with type 2 diabetes. In fact, those with low testosterone were 40% more likely to die (all-cause mortality) than those with higher levels. However, when given as a transdermal gel to hypogonadal men, there is either no significant change or only minor changes in HDL levels (28,31,32).
In this review, hypogonadism will be used as a general term to refer to any state characterised by low blood testosterone levels. Testosterone treatment is contraindicated in subjects with prostate cancer or benign prostate hyperplasia and risks of treatment are perceived to be high by many physicians. Restoration of testosterone levels to the normal range improves libido, sexual function, and mood; reduces fat body mass; increases lean body mass; and improves bone mineral density.
The hypothalamus secretes gonadotropin-releasing hormone (GnRH) that acts on the anterior pituitary to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The regulation of testosterone production in eugonadal men depends on the HPG axis depicted in Figure 1. The different names have arisen as authors try to separate the hypogonadism resulting from natural ageing from, for example, the hypogonadism caused by testicular trauma. There is a high prevalence of hypogonadism in the middle- and older-aged male population and various prevalence figures have been described in a number of studies.
