AbstractProstate cancer (PC) is known as an androgen-dependent tumor with testosterone as its natural growth factor, its action is mediated by the androgen receptor (AR) important for the biology and progression of PC. During aging a progressive decline in testosterone levels begins, caused by disability of aged Leydig cells to produce testosterone in response to luteinizing hormone. Surgical treatment of PC can influence the hypothalamic-pituitary-gonadal axis with less impact on it compared to patients treated with radiation. Patients with pre-operative low baseline testosterone level had mean Gleason score higher and AR expression was higher; significantly lower testosterone levels were recorded in patients with lymph node metastases. But some data are conflicting, and some results are opposite to those mentioned before. These data show that there is no significant association between all sex hormone in men and lethal PC or total mortality. In patients with metastatic PC, results showed that elevation of baseline androstenedione levels was predictive of prostate-specific antigen (PSA) response; higher baseline androstenedione levels were associated with an improved overall survival. In these patients, the relationship between serum testosterone and PC prognosis varies in different clinical settings and according to androgen deprivation therapy administration.
