Within this study, the administration of either omega-3 or sunflower oil for 12 weeks has no obvious impact on sperm count or sperm motility but significantly elevated the amount of morphologically abnormal sperms indicating spermatogenesis failure. Kisspeptin is actually a considerable stimulus towards the secretion of GnRH and gonadotrophins [52, 53], in addition to a reduction in GnRH and gonadotropin secretions, in addition to a subsequent lower in PRMT4 Inhibitor Storage & Stability testosterone synthesis by Leydig cells, impairs the approach of spermatogenesis. Within this study, the administration of omega-3 or sunflower oil inhibited the kisspeptin-GnRH signaling cascade, which additional decreases LH, FSH, and testosterone production. Testosterone levels have already been shown to increase in rats [54] and reduce in humans [55], dogs [48], and boars [56] immediately after fish oil supplementation. The production of testosterone in Leydig cells is controlled by quite a few genes like STAR, CYP11A1, 3-HSD, CYP17A1, and 17-HSD. The results herein demonstrated downregulation of those genes by sunflower oil or omega-3 administration, indicating steroidogenesis suppression. Steroidogenesis is decreased by omega-6 PUFAs via its direct effects on StAR and cytochrome P450 [40, 57]. By the nonreversible action of aromatase (CYP19), testosterone can be aromatized to E2 [58]. Within this study, the downregulation of testicular CYP19 mRNA levels contributed to decreased intratesticular levels of E2 following sunflower oil and omega-3 administration. On the other hand; the serum levels of E2 were considerably increased, indicating an extratesticular conversion of testosterone to E2. It has been reported that E2 stimulates the secretion of prolactin [59, 60] and increases prolactin mRNA levels [61]. Additionally, acute hyperprolactinemia has been shown to suppress the synthesis of testosterone and male fertility through inhibiting the secretion of GnRH [62], which subsequently inhibits LH pulses [63]. In addition, chronic therapy with prolactin has been demonstrated to lower the expression levels of kisspeptin and GnRH in female mice [64]. As a result, sunflower oil- and omega-3-induced hyper-prolactinemia may possibly be attributed for the repression of kisspeptin-GnRH s.
