ABSTRACT
Men with diabetes have negative effects on reproduction that causes sexual dysfunction. Medicinal plants are non-toxic and much safer than synthetic drugs because regular use of synthetic drugs shows long-term side effects. Curcuma amada (Roxb) is a medicinal plant used in Ayurveda and Unani medicinal systems in India. The goal of this study is to rummage the potential efficiency of the most potent solvent fraction of effective extract of hydro-methanol 60:40 of C. amada rhizome on male gonadal hypofunction in streptozotocin-induced diabetic rat. Diabetes-induced testicular hypofunction was evaluated by glycemic, spermiological, biochemical, genomic, flow cytometric, and histology of testicular tissue. The n-hexane, chloroform, ethyl-acetate, and n-butanol solvent fractions of the said extract were administrated for 4 weeks at 10 mg dose/100 g body weight/day. Among all the used fractions, the ethyl-acetate solvent fraction-treated group showed maximum recovery in serum insulin (177.42%), sperm count (92.84%), sperm motility (97.15%), and serum testosterone (164.33%). The diabetic rats treated with ethyl-acetate solvent fraction also exhibited the maximum resettlement in flow cytometric analysis of sperm viability (55.84%) and sperm mitochondrial integrity (149.79%), gene expression patterns of key markers for androgenesis (Δ5, 3ß-HSD 87.50%, and 17ß-HSD 74.66%) and apoptosis (Bax 44.63%, Bcl-2 54.03%, and Caspase-3 35.77%) along with testicular histology. The ethyl-acetate fraction contains alkaloids, flavonoids, and polyphenols where all of these components are not present in other fractions, may be the most effective cause for the recovery of diabetes-linked oxidative stress-mediated testicular hypofunctions. PRACTICAL APPLICATIONS: Nowadays worldwide, the use of synthetic drugs are reduced due to their toxic effect. At present, synthetic drugs are replaced by several herbal drugs, the natural source of medicine which has many therapeutic values. C. amada has strong antioxidant activity due to the presence of bio-active compound(s) that can able to manage streptozotocin-induced diabetes linked to oxidative damage of male gonadal organs. Therefore, these bio-active compound(s)-containing said medicinal plant may use as a good source of antioxidative food in the food industry as nutraceuticals and in pharmaceutical industries for the development of the herbal drug to manage diabetes-linked male gonadal hypofunctions. At present, WHO also gives emphasis for developing one drug-multi-disease therapy. From such a viewpoint, this active fraction-containing phytomolecules may have corrective efficacy against diabetes as well as oxidative stress-linked testicular complications.

Background The present investigation focuses the diabetes-induced testicular hypofunction and its possible correction by the effective dose of ethyl-acetate fraction of methanolic extract of Camellia sinensis leaves through dose-dependent study in streptozotocin-induced diabetic rat. Methods The androgenic, spermiological, oxidative stress and apoptosis sensors along with testicular genomic sensors were evaluated in a dose-dependent fashion (50âmg or 100âmg or 200âmg/kg body weight). Activities of hepatic transaminases for toxicity assessment were also measured. Results Increased level of fasting blood glucose, testicular cholesterol, seminal vesicular fructose along with a low count, motility and viability of epididymal sperm, low activities of testicular Δ5, 3ß-hydroxy steroid dehydrogenase (HSD), 17ß-HSD, testicular antioxidant enzymes (catalase and superoxide dismutase) and low plasma level of testosterone were noted in diabetic rat in respect to the control. After oral administration of said fraction to diabetic rat, levels of above sensors were resettled toward the control. A significant decrease in the number of different generations of germ cells at the stage VII of spermatogenesis in diabetic rat was noted which were recovered significantly toward the control in the fraction-treated diabetic group. It was supported by the correction in gene expression of testicular Δ5, 3ß- HSD, 17ß- HSD, Bcl-2 and Bax in the fraction-treated diabetic group. Conclusions The threshold dose of ethyl-acetate fraction of methanolic extract of C. sinensis leaves is 100âmg/kg body weight for the recovery of testicular hypofunction in a diabetic rat model.

This study was designed to explore the cyproterone acetate (CPA)-induced andrological hypofunction and its correction by oral administration of lycopene. In this concern, spermatogenic, biochemical, histological and genomic profiles were studied. Cyproterone acetate administration for 1 month helped to develop infertile model rats. A significant recovery was noted in sperm motility, sperm count, sperm viability, hypo-osmotic swelling tail-coiled spermatozoa; activities of testicular ∆5 , 3ß-hydroxysteroid dehydrogenase (HSD), 17ß-HSD, catalase (CAT) and superoxide dismutase (SOD); and levels of conjugated diene (CD), malondialdehyde (MDA), testicular cholesterol and serum testosterone after the administration of lycopene at 1.5 mg/0.5 ml Tween-80/100 g body weight/day for last 1 month to infertile model rats. Simultaneously, qRT-PCR study of Bax, Bcl-2, caspase-3, ∆5 , 3ß-HSD and 17ß-HSD genes in testicular tissue showed a significant rectification towards the control in CPA-pre-treated cum CPA-lycopene-cotreated rats. Side-by-side histological and histometric studies showed a significant correction in qualitative analysis of spermatogenesis and seminiferous tubular diameter (STD) in CPA-pre-treated cum CPA-lycopene-cotreated rats. Lycopene showed outstanding efficacy in the management of CPA-induced testicular hypofunction with special reference to correction in oxidative stress-induced testicular apoptosis at genomic level.
