Therefore, ICA II, which lacks a glucose group at C-7, is the major metabolite of ICA and has higher activity than ICA (22). so, when body weight conversion is applied, the correct icariin dosage in human for testosterone boosting will be: Where a lower icariin dosage is recommended, for instance, for bone health, the right daily dosage for people weighing 150 pounds, 200 pounds and 250 pounds will range from 11 to 110 milligrams, 15 to 150 milligrams and 18 to 180 milligrams, respectively. LC-MS/MS method for the simultaneous determination of icariin and its major metabolites in rat plasma. Introduction Epimedium species (aka horny goat weed) have been utilized for the treatment of erectile dysfunction in Traditional Chinese Medicine for many years. Icariin promotes mouse Leydig cell testosterone synthesis via the Esr1/Src/Akt/Creb/Sf-1 pathway. The underlying mechanisms appears to involve two aspects: (i) icariin promotes differentiation of endogenous stem cells to Schwann cells, which help to repair the damaged neural pathway for erection; (ii) on this basis, sildenafil can further improve penile engorgement through the cyclic guanosine monophosphate-dependent smooth muscle relaxation. Besides increasing testosterone levels, the supplement also boosts nitric oxide signaling and the result of that is lean muscle tissue increment, improved muscle repair, stronger metal drive for better gym performance and power burst. Effects of icariin on cGMP-specific PDE5 and cAMP-specific PDE4 activities. The aim of this review was to summarize the contemporary evidence regarding the pharmacokinetics, therapeutic properties, and molecular biological mechanisms of ICA and some ICA derivatives for erectile dysfunction therapy. Meanwhile, the expression trend of p38 MAPK in the penis was basically the same as that of S100, suggesting that the p38 MAPK signaling pathway may be involved in this process (69). It Helps in Bodybuilding and Performance in Sports When taken to treat erectile dysfunction and improve sex drive, Icariin causes an inhibiting effect on phosphodiesterase type 5 (commonly known as PDE5). Its thought that this also applies to humans as well. Identification of novel TGF-beta /Smad gene targets in dermal fibroblasts using a combined cDNA microarray/promoter transactivation approach.

The regulation of these pathways by ICA and ICA derivatives ultimately leads to increased proliferation and differentiation of stem cells and inhibition of apoptosis and fibrosis. Another way in which icariin has been found to improve the hearts function in animals, including human beings, is by reducing matrix metalloproteinase (MMP) function in a case involving heart failure. This can help with joint pain and numbness. (54) reported that diabetic ED rats treated with ADSCs and ICA showed significant improvement in the intracranial pressure (ICP) and ICP/mean arterial pressure (MAP) values. Effects of Icariin on Reproductive Functions in Male Rats However, this study has less experimental data and lack of in vitro mechanism studies. 15 Methods Of Treatment And Prevention Of Erectile Dysfunction (64) found that ICA II (1.5 mg/kg/day for 4 weeks) improved erectile function and smooth muscle pathological changes through activation of endogenous stem cells in obesity-related ED rats. In addition, YS-10, a new flavonoid based on the ICA II structure, treated rats with bilateral cavernous nerve injury (BCNI) and showed a significant reduction in smooth muscle atrophy, collagen deposition, endothelial and neurological dysfunction (43). Icariin from Epimedium brevicornum attenuates chronic mild stress-induced behavioral and neuroendocrinological alterations in male Wistar rats. In theory, if ED is caused by high blood pressure .
