“…There was no difference (p> 0.05) in the parameter of progressive motility (PGM) by collection (1st, 2nd and 3rd) and by treatment (T1 = BotuCrio® without addition of salmon oil and T2 = Botu-cryo® diluent + 2% oil Of salmon). These results corroborate with Grady et al (2009), that when supplementing fish oil as a source of omega three (ω3) in the diet of stallions, did not observe improvement in the parameters of motility and progressive motility in equine fresh, refrigerated and cryopreserved semen. Like Brinsko et al (2005), when adding docosahexaenoic acid (DHA) in the diet of stallions did not observe improvement in the quality of the equine semen to fresh, refrigerated and cryopreserved.…”

SUMARY The aim of the present study was to verify the effect of salmon oil addition on cryopreservation of equine semen. The experiment consisted of two treatments. Treatment 1 (T1) (control diluent), BotuCrio® was used without addition of salmon oil and treatment 2 (T2) (experimental diluent) BotuCrio® plus (with) 2% salmon oil. Three ejaculates of four stallions were used, totalizing 12 collections (n=12). Overall motility and progressive motility were evaluated by the Hamilton Thorn Research (HTR) Ceros 10.8 program, as well as the plasma membrane functionality through the hyposmotic test. Both treatments did not present statistical differences in relation to motility (T1 25,2±1,7 a, T2 29,7±1,9 a) and progressive motility (T1 11,0±1,1 a, T2 14,1±1,3 a). With respect to the hyposmotic test, the treatment 2 plus 2% of Salmon oil, presented better protection of sperm membrane functionality in relation to the control treatment (T2 77,3±1,0 a, T1 68,0±1,0 b). It can be concluded that salmon oil, although not altering the total and progressive motility, confers a better efficiency of sperm membrane functionality after thawing in equine semen.

“…Phospholipids also contribute to membrane permeability and flexibility, and cell functionality. Because the cholesterol to phospholipids proportion cannot be altered in sperm due to its dependence on species’ genetic factor [32], addition of PUFAs to diets has been suggested in order to increase its proportion relative to sperm membrane phospholipids and improve its fluidity and resistance to thermal stress [33]. Moreover, dietary fatty acids supplementation has been reported to improve the cryopreserved stallion semen [34].…”

Background Nigerian Cannabis sativa (hemp) causes male gonadotoxicity by inducing hyperprolactinemia, down-regulation of hypothalamic-pituitary-testicular axis, and oxidative stress. Benin republic hemp has been preferred by illicit users in Nigeria but its effect on male fertility is not understood. This study determined and compared the compositions of Benin republic hemp ethanol extract (BHE) and Nigerian hemp. The effects of BHE on semen parameters, reproductive hormones, and anti-oxidant status, and the possibility of bromocriptine (prolactin inhibitor) to abolish hemp-induced toxicities in rats were also investigated. Methods Thirty-six male Wistar rats were blindly randomized into 6 oral treatment groups ( n = 6 each). Groups I (control) and II received normal saline and bromocriptine (3 mg/kg) respectively. Groups III and IV received 2 mg/kg of BHE alone and in combination with bromocriptine respectively, while groups V and VI received 10 mg/kg BHE alone and in combination with bromocriptine respectively. Comparisons among the groups were done by one-way analysis of variance, followed by post-hoc Tukey multiple comparison test. Statistical significance was considered at p < 0.05. Results The BHE has no cannabichromene and tetrahydrocannabinol but a very small quantity of cannabinol and higher quantity of fatty acids when compared to Nigerian hemp. Both doses of BHE increased sperm count, morphology and viability but not motility. Co-administration of BHE with bromocriptine lowered sperm count but increased sperm morphology and viability. Bromocriptine and/or BHE caused reduction in the plasma prolactin level, increase in the plasma superoxide dismutase activity, but no significant change in the plasma gonadotropin releasing hormone, follicle stimulating hormone (except for the increase in rats that received bromocriptine+ 10 mg/kg BHE), luteinizing hormone, estradiol, malondialdehyde and glutathione peroxidase. The 10 mg/kg BHE or bromocriptine+BHE (both doses) increased total anti-oxidant capacity and catalase. Conclusions The BHE improves semen parameters by reducing plasma prolactin and enhancing plasma anti-oxidant status. Its pro-fertility potential might be associated with its deficiency in the widely known gonadotoxic phytocannabinoids.
