Testosterone is the primary androgen — or male hormone — in your body. Low testosterone affects up to 39 percent of adult men in the US over the age of 45, and becomes increasingly prevalent ...
Exogenous testosterone may also cause suppression of spermatogenesis, leading to, in some cases, infertility. [30] It is recommended that physicians screen for prostate cancer with a digital rectal exam and prostate-specific antigen (PSA) level before starting therapy, and monitor PSA and hematocrit levels closely during therapy.

[40] 5α-DHP is a major hormone in circulation of normal cycling and pregnant women. [ 41 ] Other enzymes compensate to a degree for the absent conversion of 5α-reductase, specifically with local expression at the skin of reductive 17β-hydroxysteroid dehydrogenase , and oxidative 3α-hydroxysteroid dehydrogenase and 3β-hydroxysteroid ...
[64] [58] Symptoms that may indicate liver dysfunction include nausea, vomiting, abdominal pain, fatigue, anorexia, "flu-like" symptoms, dark urine, and jaundice. [64] As of 2022, at least 10 case reports of bicalutamide-associated hepatotoxicity or liver failure, two of which were fatal, have been published in the literature.
Dihydrotestosterone (DHT, 5α-dihydrotestosterone, 5α-DHT, androstanolone or stanolone) is an endogenous androgen sex steroid and hormone primarily involved in the growth and repair of the prostate and the penis, as well as the production of sebum and body hair composition.
Uniquely among AAS, mesterolone has very high affinity for human serum sex hormone-binding globulin (SHBG), about 440% that of DHT in one study and 82% of that of DHT in another study. [ 17 ] [ 2 ] [ 18 ] As a result, it may displace endogenous testosterone from SHBG and thereby increase free testosterone concentrations, which may in part be ...
Hypogonadism means diminished functional activity of the gonads—the testicles or the ovaries—that may result in diminished production of sex hormones.Low androgen (e.g., testosterone) levels are referred to as hypoandrogenism and low estrogen (e.g., estradiol) as hypoestrogenism.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by pelvic or perineal pain without evidence of urinary tract infection, [8] lasting longer than 3 months, [9] as the key symptom. Symptoms may wax and wane. Pain can range from mild to debilitating. Pain may radiate to the back and rectum, making sitting uncomfortable.
