The male hormone, testosterone, is produced in limited quantities following treatment with Zeuterin, but after two years, testosterone production is similar to that in untreated dogs. [1] The continuing presence of testosterone means that, unlike surgical castration, chemical castration does not remove the risk of testosterone-associated ...
3β-Hydroxysteroid dehydrogenase/Δ 5-4 isomerase (3β-HSD) (EC 1.1.1.145) is an enzyme that catalyzes the biosynthesis of the steroid progesterone from pregnenolone, 17α-hydroxyprogesterone from 17α-hydroxypregnenolone, and androstenedione from dehydroepiandrosterone (DHEA) in the adrenal gland.
Cefazolin, also known as cefazoline and cephazolin, is a first-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [2] Specifically it is used to treat cellulitis , urinary tract infections , pneumonia , endocarditis , joint infection , and biliary tract infections . [ 2 ]
17β-Hydroxysteroid dehydrogenase inhibitors (17β-HSD inhibitors): inhibit the interconversion of androgens, including the synthesis of testosterone from the less-potent androstenedione; 5α-Reductase inhibitors (5α-RIs; SRD5A inhibitors): inhibit the conversion of testosterone into the more potent DHT
Steroid desmolases. Cholesterol side-chain cleavage enzyme (20,22-desmolase) – steroid synthesis; 17,20-Lyase (17,20-desmolase) – androgen synthesis; Steroid hydroxylases. 11β-Hydroxylase – corticosteroid synthesis
Most dominantly aggressive dogs are male, which causes many people to neuter their male canine companions. Removing testosterone can decrease the intensity of a canine's reaction to stimulus. Testosterone does not cause a behavior to occur, but its absence may decrease the occurrence of a "bad" behavior. [60]
Epitestosterone, or isotestosterone, also known as 17α-testosterone or as androst-4-en-17α-ol-3-one, is an endogenous steroid and an epimer of the androgen sex hormone testosterone. It is a weak competitive antagonist of the androgen receptor (AR) and a potent 5α-reductase inhibitor .
The drug is a synthetic androgen and anabolic steroid [6] and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). [ 5 ] [ 2 ] [ 7 ] It has strong anabolic effects and highly androgenic effects, as well as potent progestogenic effects, and weak glucocorticoid effects.
