“…Increasing PUFA sources in the diet resulted in a concomitant increase in n-3 fatty acids of sperm lipid and semen quality in boars (Rooke et al, 2001;Mitre et al, 2004) cockerels and stallions (Brinsko et al, 2005). Furthermore, we recently reported that dietary fish oil supplementation improved the total number and sperm concentration, motility and progressive motility of goat sperm during the non-breeding season (Dolatpanah et al, 2008).…”

“…Feeding shark liver oil to boars increased the proportions of n-3 and n-6 PUFAs in sperm lipids, particularly DHA, compared to control (Mitre et al, 2004). Feeding PUFAs increased sperm lipid content in several species (Mitre et al, 2004;Zaniboni et al, 2006); fish oil as a source of n-3 fatty acids improved the semen quality in goats (Dolatpanah et al, 2008), boars (Rooke et al, 2001) and turkeys .…”

The fatty acid composition of sperm affects the fertilization rate. The objective was to investigate the effects of dietary fish oil (as a source of n-3 fatty acids) on semen quality and sperm fatty acid composition in sheep. Eight Zandi fat-tailed rams were randomly allocated into two groups and fed either a control diet or a diet supplemented with fish oil. Both diets were isocaloric and isonitrogenous and were fed for 13 weeks, starting in the middle of the breeding season. Semen samples were collected weekly and their characteristics evaluated by standard methods, whereas samples collected at the start and end of the study were assessed (gas chromatography) for sperm lipid composition. Mean (6s.e.m.) sperm concentrations (4.3 3 10 9 6 1.3 3 10 8 v. 3.9 3 10 9 6 1.3 3 10 8 sperm/ml and percentages of motile (77.25 6 3.34 v. 60.8 6 3.34) and progressively motile sperm (74.13 6 1.69 v. 62.69 6 1.69) were significantly higher in the fish oil group than control. Dietary fish oil increased the proportion of docosahexaenoic acid (DHA, C22:6 n-3) in sperm fatty acid composition. We concluded that feeding fish oil as a source of n-3 fatty acids attenuated seasonal declines in semen quality in rams, perhaps through increased DHA in sperm.

Oxidative stress affects sperm performance and ejaculate redox status in subordinate House Sparrows

Oxidative stress is the result of random cellular damage caused by reactive oxygen species that leads to cell death, ageing or illness. Most physiological processes can result in oxidative stress, which in turn has been identified as a major cause of infertility. In promiscuous species, the fertilizing ability of the ejaculate partly determines the male reproductive success. When dominance determines access to fertile females, theory predicts that lower ranking males should increase resource investment into enhancing ejaculate quality. We hypothesized that subordinate males should thus prioritize antioxidant protection of their ejaculates to protect them from oxidative stress. We put this hypothesis to the test by chronically dosing wild house sparrows with diquat (∼1 mg kg), a herbicide that increases pro-oxidant generation. We found that, although they increased their antioxidant levels in the ejaculate, diquat-treated males produced sperm with reduced velocity. Importantly, and contrary to our hypothesis, males at the bottom of the hierarchy suffered the largest reduction in sperm velocity. We suggest that resource access hinders individuals' ability to cope with environmental hazards. Our results point at oxidative stress as a likely physiological mechanism mediating ejaculate quality, while individual ability to access resources may play a role in constraining the extent to which such resources can be allocated into the ejaculate.

“…The importance of fatty acids, especially PUFA, in sperm motility has been demonstrated in other animal species. For example, in boars fed a diet supplemented with shark oil, rich in PUFA, an improvement in sperm motility was found (Mitre et al, 2004). Again in boars, DHA and n-3 series fatty acids in sperm were positively correlated with motility (Am-in et al, 2011).…”

AgradecimientosDesde bien pequeña he tenido miedo al mar. Con el tiempo descubrí que no era miedo lo que sentía sino curiosidad. Era todo un misterio para mí lo que ocultaba el océano y esa intriga a lo desconocido, es lo que de pequeña confundía con miedo. No todo el mundo es capaz de enfrentarse a sus temores y yo me siento muy afortunada de haber tenido la oportunidad de que aquello que tanta expectación me ha causado siempre, se haya convertido en el área de estudio de mi tesis doctoral. Algunas personas han sido partícipes de que lo consiga y otras, han formado parte de estos años que para mí han sido toda una aventura. Todas ellas han colaborado para que señale esta etapa de mi vida como "inolvidable" y es por eso que siento la necesidad de agradecérselo.En primer lugar me gustaría dar las gracias a mi director de tesis, Johnny. Muchas gracias por apostar por mí todo este tiempo (aunque siempre hayamos tenido nuestras diferencias con el formato de los pósters…jeje). Siempre he tenido muy en cuenta tus consejos, te admiro y para mi has sido un referente en este período, gracias por todo Johnny. También quiero hacer mención a Luz. El trato tan afable que ha tenido siempre hacia mí, me ha hecho sentirla muy cercana y eso se agradece, muchas gracias Luz. Gracias también a los colegas daneses por colaborar con nosotros y, en especial a Ian Butts, por ofrecer su coautoría en el último capítulo.Gracias a los compañeros del grupo. Ila gracias por ser tan servicial conmigo siempre. David, gràcies per preguntarme i preocuparte sempre per la meua tesi i oferir-me la teua ajuda quan ho he necessitat. Morini, que grande el día que llegaste y te lleve "alcampo"…jaja! Gracias por los buenos momentos que hemos pasado y sabes que te debo un concierto de los Mojinos!!!... con una botella de Jägermeister quizás?.... Gracias a Pepa que aunque no hayamos coincidido mucho tiempo, me encanta su forma de ser y siempre me ha animado con la tesis, gracias Pepa! Gracias también a los compañeros de laboratorio y en especial a Javi Moya.No puedo dejar de lado mi paso por nutrición. Silvia y Ana, os estoy profundamente agradecida porque vosotras fuisteis las primeras personas que me dieron una oportunidad en el mundo de la investigación, nunca lo he olvidado y ahora que tengo la oportunidad os digo en mayúsculas: GRACIAS! Mi paso por nutrición fue breve pero me llevo muy buenos recuerdos: el hundimiento del Enterprise, Javi Todopoderoso, Nacho, Nuri, Jorge, Miguel, Andrés… y el mejor recuerdo: Silvia Nogales. Silvi, para mi has sido un poco como el señor Miyagi… estar contigo ha sido un continuo aprendizaje, aunque a veces ni me diera cuenta (…dar cera, pulir cera…jeje).Gracias a las personas más importantes en mi vida, mi familia. Gràcies mamà pel teu suport incondicional. Papa, aunque a día de hoy no tengas muy claro lo que hago con las anguilas, nunca me has cuestionado y siempre te ha bastado con verme feliz, gracias. Gracias a mi hermano y Beti que, aunque por desgracia están a miles de Km siempre me han transmitido su apoyo. Y gr...
