Indications and Uses
Testosterone is the main natural male sex hormone in mammals and is
a steroid hormone with 19 carbon atoms. It is the main male sex
hormone secreted by the testes, and it is also the most active male
sex hormone. It promotes humans’ and animals’ sex organ and
secondary sex characteristic development, sperm maturation, and
protein metabolism for muscle strengthening.
Testosterone controls the growth and development of male sex organs
and male secondary sex characteristics. It is mainly used in
replacement therapy for eunuchism, treatment for male menopause
syndrome, and treatment for impotence, and it is also used in
biochemical research.
Pharmacokinetics
Testosterone can bind non-specifically with plasma albumins in
blood, and it can also bind with plasma sex hormone binding
globulins. It can be converted into estradiol and estrone in
peripheral tissue. Testosterone is mostly degraded in the liver,
where its A-ring is restored, and it is converted into 17-
ketosteroid under the effects of 17β-Hydroxysteroid dehydrogenase.
Along with androsterone, epiandrosterone, and etiocholanlone, it is
combined with glucuronic acid or sulfate and excreted in urine. Most
metabolites in urine that are excreted by binding to glucuronic acid
belong to 17-ketosteroids.
Application in Particular Diseases
In Osteoporosis:
Testosterone replacement is not FDA approved for the prevention or treatment of osteoporosis. It should not be used solely for these indications but might be beneficial to reduce bone loss in patients needing therapy for hypogonadal symptoms. In a few studies, women receiving oral methyltestosterone 1.25 or 2.5 mg daily or testosterone implants 50 mg every 3 months had increased BMD. Various salt forms of testosterone were associated with increased BMD in some studies of hypogonadal men or senior men with normal hormone levels or mild hormonal deficiency. Transdermal gel, oral, intramuscular, and pellet testosterone products are available.
Patients using them should be evaluated within 1 to 2 months of initiation and then every 3 to 6 months thereafter.

Synthesis
Testosterone, 17β-hydroxyandrost-4-ene-3-one (29.1.5), is made in a number of ways from different substances, including cholesterol, although it is most often
made from androstenolone acetate. In order to do this, the keto-group at C17 of the steroid
system of androstenolone acetate is reduced to a hydroxyl group by either sodium borohydride, lithium aluminum hydride, or hydrogen over Raney nickel, all of which result in
a 17β-hydroxy compound. In the given example, reduction by sodium borohydride or
hydrogen over Raney nickel leads to the formation of 3β-acetoxy-5-androsten-17β-ol
(29.1.1). The hydroxyl group resulting from reduction then undergoes acylation by benzoyl chloride in pyridine, which forms a diester (29.1.2). After that, taking into consideration the differences in the acidic region of the two ester groups present in the molecule as
well as the long-known fact that 17-hydroxy-group ester derivatives are harder to
hydrolyze than 3-hydroxy-group ester derivatives, the acetyl protection of the hydroxyl
group at C3 is removed by selective hydrolysis using potassium hydroxide in ethanol, and
the resulting alcohol (29.1.3) is oxidized to a ketone (29.1.4) by aluminum isopropylate in
the presence of cyclohexanone as a hydrogen acceptor, during which isomerization of the
double bond from position C5–C6 to C4–C5 simultaneously takes place. Subsequent hydrolysis of the remaining ester region of the molecule using an alkali gives the desired testosterone (29.1.5) . When necessary to convert this into the corresponding ester
(propionate, enantate, cypionate, and a few other testosterone esters), the necessary acylation can be accomplished.
Purification Methods
Crystallise testosterone from aqueous acetone, hexane or isoPrOH. The long needles that separated from EtOH/AcOH were used for X-ray crystallography [Roberts et al. J Chem Soc Perkin Trans II 1978 1973.] The acetate [1045-69-8] crystallises from MeOH or aqueous Me2CO, with m 140-141o and [] D 20 +87.8o (c 1, EtOH). [Ruzicka et al. Helv Chim Acta 18 1478 1935 and 19 99, 842 1936, Beilstein 8 IV 974.]

Influence of whole microalgal cell immobilization and organic solvent on the bioconversion of androst-4-en-3,17-dione to testosterone by Nostoc muscorum
Arabi,Yazdi, M. Tabatabaei,Faramarzi
, p. 213 - 217 (2010)
The use of free, immobilized and reused immobilized cells of the microalga Nostoc muscorum was studied for bioconversion of androst-4-en-3,17-dione (AD) to testosterone in hexadecane. Among polymers such as agar, agarose, κ-carrageenan, polyacrylamide, polyvinyl alcohol, and sodium alginate that were examined for cell entrapment, sodium alginate with a concentration of 2% (w/v) proved to be the proper matrix for N. muscorum cells immobilization. The bioconversion characteristics of immobilized whole algal cells at ranges of temperatures, substrate concentrations, and shaking speeds were studied followed by a comparison with those of free cells. The conditions were 30°C, 0.5. g/L, and 100. rpm, respectively. The immobilized N. muscorum showed higher yield (72 ± 2.3%) than the free form (24 ± 1.3%) at the mentioned conditions. The bioconversion yield did not decrease during reuse of immobilized cells and remained high even after 5 batches of bioreactions while Na-alginate 3% was used; however, reuse of alginate 2% beads did not give a satisfactory result.

ANDROSTENEDIONE AND TESTOSTERONE BIOSYNTHESIS BY THE ANDRENAL CORTEX OF THE HORSE
Silberzahn, Pierre,Rashed, Fakhri,Zwain, Ismail,Leymarie, Pierre
, p. 147 - 152 (1984)
An homogenate from cortical tissue of mare adrenals was incubated in the presence of tritiated pregnenolone.The (3H) androstenedione and the (3H) testosterone synthesized during the incubation were extracted, purified, and co-crystallized to constant specific activity in the presence of unlabeled carriers.The rate of conversion of pregnenolone to androstenedione and testosterone was of the order of 5 and 0.15 per cent respectively.The high ratio of (3H) androstenedione to (3H) testosterone observed in this study suggests that androstenedione is the main androgen produced by mare adrenals.It is concluded that adrenals could contribute to the production of blood androgens in normal as well as hyperandrogenic mares.
The aging Leydig cell: 2. Two distinct populations of Leydig cells and the possible site of defective steroidogenesis
Chen,Lin,Murono,Osterman,Cole,Nankin
, p. 63 - 72 (1981)
Using metrizamide gradient centrifugation two populations of Leydig cells were found in both 60-90 day old and 24 month old rats. Cells from both Band 2 (B2) and Band 3 (B3) responded to LH stimulation with increased cyclic AMP formation; however, only B3 cells produced significant amounts of testosterone. Cells from both B2 and B3 of the old rats synthesized less cyclic AMP and testosterone than cells from their younger counterparts. In response to LH stimulation, 0.01 - 1.0 mIU/ml, no appreciable difference of cyclic AMP formation could be detected between young and old Leydig cells. Maximal testosterone production occurred when 1 mIU/ml LH was used. Only when LH concentration was increased to 10 and 100 mIU/ml, did young Leydig cells produce significantly more cyclic AMP than old Leydig cells. After addition of 5 x 10-7M of pregnenolone or progesterone to the incubation medium both young and old Leydig cells produced comparable amounts of testosterone. These results demonstrate no impairment of old rat Leydig cells to synthesize testosterone from pregnenolone and progesterone.

Regio- and stereoselective reduction of 17-oxosteroids to 17β-hydroxysteroids by a yeast strain Zygowilliopsis sp. WY7905
Liu, Yuanyuan,Wang, Yu,Chen, Xi,Wu, Qiaqing,Wang, Min,Zhu, Dunming,Ma, Yanhe
, p. 17 - 24 (2016/12/22)
The reduction of 17-oxosteroids to 17β-hydroxysteroids is one of the important transformations for the preparation of many steroidal drugs and intermediates. The strain Zygowilliopsis sp. WY7905 was found to catalyze the reduction of C-17 carbonyl group of androst-4-ene-3,17-dione (AD) to give testosterone (TS) as the sole product by the constitutive 17β-hydroxysteroid dehydrogenase (17β-HSD). The optimal conditions for the reduction were pH 8.0 and 30 °C with supplementing 10 g/l glucose and 1% Tween 80 (w/v). Under the optimized transformation conditions, 0.75 g/l AD was reduced to a single product TS with >90% yield and >99% diastereomeric excess (de) within 24 h. This strain also reduced other 17-oxosteroids such as estrone, 3β-hydroxyandrost-5-en-17-one and norandrostenedione, to give the corresponding 17β-hydroxysteroids, while the C-3 and C-20 carbonyl groups were intact. The absence of by-products in this microbial 17β-reduction would facilitate the product purification. As such, the strain might serve as a useful biocatalyst for this important transformation.
