“…The result of a study reporting the benefits of fish oil on male and female reproductive performance has been largely undertaken and obtained highly variable results. Cod liver oil supplementation up to 4.5% could increase testosterone levels and the quality of spermatozoa of local rabbit epididymis (Ermayanti et al, 2016), fish oil diet positively affect testes developments and spermatogenesis in the goat (Adibmoradi et al, 2012), fed a diet supplemented with LNA (n-3) can increase estradiol during the follicular phase in cows (Robinson et al, 2002), supplementation of n-3 PUFA rich fish oil significantly increased the number of pre-ovulatory follicles and ovulation rate in goat (Mahla et al, 2017), dietary PUFAs are known to mediate a broad range of actions in reproductive tissues including effect on membrane fluidity, intra-cellular cell-signalling cascades and susceptibility to oxidative injury (Wathes et al, 2007), change in the composition of dietary fatty acids not only modifies fatty acid composition in the blood plasma but also of the reproductive tissues including, follicular fluid, cumulus cells and the oocytes (Ferguson & Leese, 1999;Zeron et al, 2002;Bilby et al, 2006;Childs et al, 2008;Fouladi-Nashta et al, 2009;Wonnacott et al, 2010), which can directly influence the competence of oocytes for further development and/or fertility (Wonnacott et al, 2010;Petit et al, 2001). Fatty acids are also precursors for prostaglandins and progesterone synthesis and therefore play an important role in the regulation of normal reproductive function (Abayasekara & Wathes, 1999;Mattos et al, 2000).…”
