“…In the ovary, the steroid biosynthesis pathway produces hormones that play an indispensable role in the reproductive process (Drummond, 2006). The enzyme P450scc encoded by CYP11A1 catalyses steroidogenesis by converting cholesterol to pregnenolone, which is the precursor of all other steroid hormones (Ding et al, 2022). After ovulation, during luteinization, there is a major change as the follicular tissue changes from secreting oestradiol to secreting large amounts of progesterone (Murphy, 2000).…”

Hanper ewes that were either monotocous or polytocous provided ovarian follicles of diameter >3 mm in the follicular phase and, in the luteal phase, samples of corpora lutea that had developed from follicles of diameter >3 mm. Differentially expressed mRNAs (monotocous versus polytocous) were then identified, and their functions were predicted. Results showed that 1508 mRNAs were differentially expressed in the follicular phase, with 885 being in the luteal tissues. Those which were differentially expressed in the follicular phase were mainly involved in the regulation of the ferroptosis and lysosome signalling pathways, whereas, for the luteal tissue, the differentially expressed mRNAs were mainly involved in the regulation of steroid biosynthesis. Based on the results, it was inferred that these pathways could explain variations in the fecundity of sheep.

“…Leydig cells are responsible for testosterone production, and if they do not function properly, testosterone levels decrease. It is well known that FSH directly affects the sperm stem cells and contributes to their maturation (Ding et al., 2022 ; Eisenberg et al., 2023 ). Luteinizing hormone (LH) is a glycoprotein produced in the anterior lobe of the pituitary gland.…”

“…Luteinizing hormone (LH) is a glycoprotein produced in the anterior lobe of the pituitary gland. LH stimulates the production of the hormone testosterone in males and regulates reproductive and sexual functions (Ding et al., 2022 ; Eisenberg et al., 2023 ; Kivrak & Aydin, 2023 ). Overfeeding, underfeeding or malnutrition of breeding animals negatively affects the reproductive system.…”

BackgroundThe metabolic impacts of including soya meal, wheat gluten and corn gluten in the diet of male lambs could influence their reproductive performance.ObjectivesAn experiment was carried out to assess the effects of corn gluten, wheat gluten and soya meal on the reproductive system of male lambs.MethodsTwenty‐four male Morkaraman lambs, aged 9 months, were utilized in this study and were fed experimental diets for 56 days. The lambs were divided into a control group (soybean meal + safflower meal), a corn group (corn gluten) and a wheat group (wheat gluten).ResultsThe serum follicle‐stimulating hormone level of the control group was significantly higher and tumour necrosis factor‐alpha (TNF‐α) level was lower than the wheat and corn gluten groups (p < 0.05). The lowest malondialdehyde level in testicular tissue was observed in the control group, whereas the highest was in the wheat gluten group (p < 0.05). The glutathione level in the control group was significantly higher than in the other groups (p < 0.05). The corn gluten group showed the highest CHOP and IRE1 levels; the lowest Bcl‐2 levels and the highest IL‐1B and P2 × 7R levels were found in the wheat group; and the lowest TNF‐α levels were in the control group (p < 0.05). Additionally, the study revealed that diet had a significant impact on spermatological parameters of the testis such as diameter, volume and weight (p < 0.05).ConclusionsThese results concluded that the inclusion of different protein sources in the diet of reproductive male lambs affects the metabolism of testicular tissue.
