Cordyceps militaris (CM) is a popular medicinal fungus; however, few studies have focused on its impact on the male reproductive system. We evaluated the effects of CM fermentation products on the reproductive development of juvenile male (JM) mice. Mice were divided into four experimental groups, each fed 5% CM products (weight per weight (w/w) in normal diet): extracellular polysaccharides (EPS), fermentation broth (FB), mycelia (MY), and whole fermentation products (FB plus MY, FBMY) for 28 days, while mice in the control group (CT) were fed a normal diet. Basic body parameters, testicular structure, sperm parameters, and sex hormones concentrations were analyzed. Compared to the CT group, mice in the EPS, MY, and FBMY groups showed a significantly increased mean seminiferous tubule area (p < 0.05), mice in the FB and MY groups had significantly higher sperm concentrations (p < 0.05), and mice in the EPS, FB, and FBMY groups showed significantly increased ratios of motile s...

Age-related male sexual dysfunction covers a wide variety of issues, together with spermatogenic and testicular impairment. In the present work, the effects of cordycepin (COR), an active constituent of a nutrient powerhouse Cordyceps militaris Linn, on senile testicular dysfunction in rats was investigated. The sperm kinematics, antioxidant enzymes, spermatogenic factors, sex hormone receptors, histone deacetylating sirtuin 1 (SIRT1), and autophagy-related mammalian target of rapamycin complex 1 (mTORC1) expression in aged rat testes were evaluated. Sprague Dawley rats were divided into young control (2-month-old; YC), aged control (12-month-old; AC), and aged plus COR-treated groups (5 (COR-5), 10 (COR-10), and 20 (COR-20) mg/kg). The AC group showed reduced sperm kinematics and altered testicular histomorphology compared with the YC group (p < 0.05). However, compared with the AC group, the COR-treated group exhibited improved sperm motility, progressiveness, and average path/...
Effect of herbal supplements (nettle and rosehip) on the sperm quality in Danube White breed boars

Yordanova, G., Kanev, D., Marchev, Y., Nedeva, R., Nikolova, T., & Palova, N. (2020). Effect of herbal supplements (nettle and rosehip) on the sperm quality in Danube White breed boars. Bulg. J. Agric. Sci., 26 (5),1020–1023 An experiment with 5 boars from the Danube White breed, raised and fed individually, was conducted in Agricultural Institute – Shumen. The experiment was divided into two sub-periods – a 40-day control period and an experimental period with the same duration. During the control period the animals were fed with combined fodder, containing 16.4% crude protein, 0.80% lysine, 1.3% calcium, 0.68% phosphorus, and during the second sub-period – 15.5% crude protein, 0.85% lysine, 0.63% calcium and 0.45% phosphorus. In the experimental period the boars were fed with the same combined fodder, to which was added 20 g of herbal supplement (nettle and flour from rosehip) per day per boar. From each boar was taken 10 ejaculates during the control period and 11 ejaculates duri...
