Abstract
This study aimed to determine the effect of alpha-lipoic acid (ALA) on post-thaw quality of bee semen. In the study, semen from sexually mature drone were collected. A series of experiments were carried out in which the retrieved semen was diluted with diluents containing different ALA concentrations or without ALA supplement (control). Cryopreserved sperm were thawed, and evaluated for motility (phase-contrast microscope), plasma and acrosomal membrane integrity, mitochondrial membrane potential, and DNA fregmantation. The results obtained showed that the highest motility after thawing was observed in the groups containing ALA 0.25 mmol (P < 0.05). Likewise, plasma membrane integrity was found to be better preserved in the ALA 0.25 mmol-added group than in other groups. Acrosomal integrity were also higher in the ALA-containing groups than in the control group (P < 0.05). The results of this study show that ALA supplementation especially at 0.25 mmol improved post-thawed sperm motility, plasma membrane functionality, and mitochondrial membrane potantial quality of honeybee semen.

Abstract
The anti-Müllerian hormone (AMH) indicates ovarian reserve in cattle, maintaining a consistent trajectory post-puberty. In heterosexual pregnancies, the development of the Müllerian duct in female foetuses is inhibited, resulting in an anticipated minimal or absent ovarian reserve capacity. This investigation aimed to compare AMH levels in healthy Holstein heifers that had reached puberty with those of freemartin animals of the same breed and age. The study incorporated Holstein heifers reaching puberty between 11 and 15 months of age in Group 1 (G1, n = 20) and freemartin animals in Group 2 (G2, n = 19, 16). AMH measurements (AMH-1/AMH-2) were recorded at 12-day intervals for the study participants. Notably, AMH levels in three freemartin animals could not be detected, prompting statistical analysis based on measurements from the remaining 16 freemartin animals in G2. A statistically significant correlation was observed between two separate measurements in G1 and G2 (p < .001). Furthermore, AMH-1 and AMH-2 levels were statistically higher in G1 than in G2 (p < .001). In G1, AMH-1 levels ranged from 227 to 677 pg/mL, with an average of 367.3 ± 25.5 pg/mL, and AMH-2 levels ranged from 234 to 645 pg/mL, with an average of 380.8 ± 24.4 pg/mL. Conversely, in G2, AMH-1 levels ranged from 10 to 72 pg/mL, with an average of 26.8 ± 4.44 pg/mL, and AMH-2 levels ranged from 12 to 68 pg/mL, with an average of 28.75 ± 4.18 pg/mL. The mean AMH levels in G1 were approximately 14 times higher than in G2 (p < .001). Consequently, ROC analysis utilizing AMH-1 and AMH-2 data established cut-off values of ≤72 and ≤ 68 pg/mL respectively for distinguishing freemartin animals. In conclusion, AMH could be used as a reliable biomarker for identifying Holstein freemartin animals.

Abstract
In this study, it was aimed to determine the effect of destruction of lyophilized and frozen-thawed ram sperm plasma and acrosomal membrane on development of embryos produced by intracytoplasmic sperm injection (ICSI). Semen samples were divided into two groups for lyophilization (L) and freezing (F). For the removal of the plasma membrane, L and F groups were incubated with Triton X-100 (LTX-100 and FTX-100, respectively). Integrities of the plasma membrane, acrosome and chromatin structure were evaluated. Oocytes were injected with these sperm groups. Although no plasma membrane and acrosome integrities of the L (0.0%) group were detected, the plasma membrane integrity of the F group (69.4%) was significantly higher than the FTX-100 group (23.6%) (p < 0.05). The acrosome integrity of the FTX-100 group (3.80%) was significantly lower than the F group (55.6%) (p < 0.05). The chromatin integrities of L and F groups were higher than the Triton X-100 treated groups (p < 0.05). ICSIs with L, LTX-100, F and FTX-100 sperm were produced similar cleavage and blastocyst rates. In conclusion, data presented here confirm that ram spermatozoa can effectively be lyophilized and injected into oocytes for initiation of embryonic development and Triton X-100 pretreatment is not necessary while using lyophilized and frozen semen.

Abstract
The objective of the current study was to evaluate the effect of autologous platelet-rich plasma (PRP) addition into soybean lecithin based extender on buck semen at post-thaw. Semen samples were collected from eight Saanen buck, and each semen sample was split into four equal aliquots and diluted with different concentrations of PRP supplemented extenders [no PRP (control), 0.5 × 107/ml PRP, 1 × 107/ml PRP, or 2 × 107/ml PRP]. Motility, plasma membrane functional integrity, acrosome integrity, mitochondrial membrane potential, DNA integrity and malondialdehyde concentrations (MDA) were measured and analyzed at post-thaw. The results showed that 2 × 107/ml PRP group had a positive effect on motility (62.41 ± 4.24), membrane functional integrity (71.11 ± 2.90), mitochondrial membrane potential (69.70 ± 1.99), DNA integrity (7.22 ± 0.93) and MDA levels (2.56 ± 0.73) at post-thaw (P < 0.05). The results of the study demonstrated that autologous PRP has a protective effect on cryopreservation of buck spermatozoa and the fertility effects are worthy of further study.

Abstract
The aim of the present study was to evaluate the effects of an alpha-lipoic acid-supplemented extender on ram semen at a post-thaw stage and after incubation (6 hr). Semen samples were collected from five Kivircik Rams. Pooled semen was diluted with an egg yolk-based extender with different concentrations of alpha-lipoic acid (0.25 mmol L-1 , 0.5 mmol L-1 and 1 mmol L-1 ) and without alpha-lipoic acid. Motility, plasma membrane functional integrity (HOST), acrosome integrity (FITC-Pisum sativum agglutinin) and DNA integrity (TUNEL) were assessed at post-thaw and 6 hr after incubation of the frozen-thawed semen. At the post-thaw stage, 0.25 mmol L-1 alpha-lipoic acid had a positive effect on sperm motility and plasma membrane functional integrity compared to the control group (p < .05). At the post-incubation stage (6 hr), it was determined that the motility and plasma membrane functional integrity of the antioxidant groups were adversely affected compared to the control group (p < .05) and 1 mmol L-1 dose of alpha-lipoic acid had a harmful effect on DNA integrity compared to the control group (p < .05). The results of the study demonstrated that alpha-lipoic acid has positive effects at post-thaw but have harmful effects on long term to ram semen.

Abstract
The objective of this study was to determine the optimum concentrations of rainbow trout seminal plasma (RTS) supplemented extenders for goat semen quality at post-thaw and after incubation. Five sexually mature Saanen goat (Capra aegagrus hircus) were used for semen collection. Pooled semen was diluted with soybean lecithin-based extender without RTS (control) or supplemented with different concentrations of RTS (1%, 2%, 4% or 8%), at a final concentration of 150 × 106 spermatozoon/ml. Sperm motility, plasma membrane functional integrity (HOST), damaged acrosome (PSA-FITC), mitochondrial activity (rhodamine123) and DNA integrity (TUNEL) were evaluated. Spermatological parameters were evaluated at post-thaw and after 6 hr incubation. RTS8 group preserved sperm motility, acrosomal integrity, plasma membrane functional integrity and mitochondrial function better than the control group (p < .05). The study demonstrated that RTS supplemented lecithin-based extenders have useful effects on goat spermatozoa. In addition, the results of the current study represented the positive effect of using 8% RTS supplemented extender.

Abstract
The aim of the present study was to evaluate different concentrations of royal jelly (RJ) supplemented extenders for post-thawing quality of drone sperm. Semen samples were collected from sexually mature drones. Pooled semen was diluted with extender without RJ (control) or supplemented with different concentrations of RJ (1, 2, 4 or 8%). Sperm motility, plasma membrane functional integrity, and acrosomal integrity were evaluated. At post thaw, the highest sperm motility and acrosomal integrity rates were obtained in the RJ1 group. Functional integrity of sperm membrane was better preserved in the RJ1 and RJ2 groups compare to the other groups. The study shows that RJ supplemented extenders have beneficial effects on drone semen parameters. The results of the present study demonstrated advantage of using 1% RJ supplemented extender.

Abstract
Brain histamine holds a key position in the regulation of behavioral states, biological rhythms, body weight, energy metabolism, thermoregulation, fluid balance, stress and reproduction in female animals. However, it is not clear whether central histamine exerts any effect on hypothalamic-pituitary-testicular in male rats and if so, the involvement of type of central histamine receptors. The current study was designed to determine the effect of centrally administrated histamine on plasma gonadotropin hormone-releasing hormone (GnRH), luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone level, and sperm parameters, and to show the mediation of the central histaminergic H1, H2 and H3/H4 receptors on histamine-evoked hormonal and sperm parameters' effects. Studies were performed in male Sprague-Dawley rats. A total of 50 or 100 nmol doses of histamine were injected intracerebroventricularly (icv). 100 nmol dose of histamine significantly caused increases in plasma GnRH, LH, FSH and testosterone levels of animals, but not 50 nmol dose of histamine. Moreover, central pretreatment with chlorpheniramine, histaminergic H1 receptor antagonist (100 nmol), ranitidine and histaminergic H2 receptor antagonist (100 nmol) completely prevented histamine evoked increase in plasma GnRH, LH, FSH and testosterone levels, while thioperamide, histaminergic H3/H4 receptor antagonist (100 nmol) pretreatment failed to reverse sex hormones responses to histamine. Both central histamine treatment alone and central histamine treatment after central histaminergic receptors antagonists' pretreatments did not alter any sperm parameters in rats. In conclusion, our findings show that centrally administered histamine increases plasma GnRH, LH, FSH and testosterone levels of conscious male rats without change any sperm parameters. Moreover, according to our findings, central histaminergic H1, and H2 receptors mediate these histamine-induced effects.

Abstract
The aim of this study was to determine the effects of the administration time of misoprostol
(11 h (Miso11) and 6 h (Miso6) before artificial insemination) on fertility rates in Kivircik
ewes (control: n = 41, Miso11: n = 32 and Miso6: n = 33) during breeding season. Artificial insemination
(AI) was performed 48 h after sponge removal using frozen-thawed semen (150 million sperm
per dose in 0.25 ml straws). Estrus synchronization parameters (onset and duration) and lambing
rate were evaluated. No significant difference was observed among groups for the estrus onset
and duration hours (P > 0.05). The lambing rates in the control, Miso11 and Miso6 groups
were 39.0, 62.5 and 54.5%, respectively. There were significant differences among the control,
Miso11 and Miso6 groups according to lambing rates (P < 0.05). In conclusion, misoprostol
treatment significantly improved fertility in ewes when using frozen-thawed semen in AI.
Administration of misoprostol 11 h before AI resulted in a higher lambing rate than that at
6 h before AI; therefore, treatment of misoprostol 11 h before AI can effectively be used.

Abstract
The aim of this study was to demonstrate the possible individual and/or synergistic effects of β-glucan and dietary restrictions on the reproductive parameters of rats. For this purpose, forty male Sprague-Dawley rats were randomly divided into four equal groups (n = 10 per group). The first group was the control, the second group was kept under dietary restriction (DR), the third group was kept under a dietary restriction and given β-glucan (DR + βG) and the fourth group was supplemented only with β-glucan (βG; 20 mg/kg) intragastrically for 14 days. Motility, vitality and morphology of spermatozoa, reproductive organ weights (testis, vesicula seminalis and epididymis) and seminiferous tubule diameters were evaluated in experimental rats. β-glucan had excellent effects on motility, live spermatozoa rate and the acrosome integrity when compared to the control group (p < 0.05). We also observed that β-glucan administration to rats having dietary restriction could improve sperm motility and acrosome integrity (p < 0.05). While the β-glucan improved seminiferous tubule diameter (p < 0.05), weights of the reproductive organs did not change positively as a result. This study demonstrated that β-glucan treatment significantly improved some spermatological characteristics in rats. Therefore, treatment with β-glucan could be used for its positive effects on motility, spermatozoa vitality rate and acrosome integrity for infertile men.

Abstract
The scope of this study was investigation the affects of various antioxidants on 1% soybean lecithin-based semen extenders for ram semen cryopreservation. Ejaculates, collected via electrically stimulated ejaculation, that have a thick consistency, rapid wave motion (3-5 on a 0-5 scale) and >75% initial motility were pooled. The pooled samples were split into four equal aliquots as 5 mM Methionine, 5 mM Cysteamine, 1 mM Cysteine and a sample of antioxidant-free control group. Each sample group was diluted to a ratio of 1/5 (semen/extender, v/v) as final concentration and two step dilution method was used for cryopreservation. Extender groups were assessed for sperm motility, plasma membrane functional integrity using hypoosmotic swelling test (HOST), damaged acrosome using FITC-Pisum sativum agglutinin (PSA-FITC) and DNA integrity using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). Semen samples also incubated for 6 h in humidified air with 5% CO2 at 39 °C to evaluate post-thaw incubation resilience of semen characteristics. The results showed that freezing and thawing procedures had negative effects on motility (P < 0.05), plasma membrane integrity (P < 0.05) and acrosomal integrity (P < 0.05). After 6 h of incubation time, the Cysteine supplemented extender group yielded significantly higher results than other extender groups in terms of spermatological parameters. Furthermore MDA levels in the antioxidant groups were lower than control group (P < 0.05). Nevertheless, there were no significant differences among antioxidant groups.

Abstract
The aim of this study was to evaluate the effects of lyophilized egg yolk extender on ram semen cryopreservation. Ejaculates with a thick consistency, rapid wave motion (3-5 on a 0-5 scale) and >75% initial motility were pooled. Sperm were diluted to final concentration of 1/5 (semen/extender) in lyophilized egg yolk or fresh egg yolk extenders using two-step dilution method. The equilibrated semen was frozen in 0.25 mL straws. Semen samples were assessed for sperm motility, plasma membrane functional integrity using hypoosmotic swelling test (HOST), damaged acrosome using FITC-Pisum sativum agglutinin (PSA-FITC) and DNA integrity using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) at three time points: after dilution with extender A, equilibration and post-thaw. The results showed that freezing and thawing procedures (dilution, equilibration and thawing) had negative effects on motility (P<0.001), plasma membrane integrity (P<0.001), acrosome integrity (P<0.001) and DNA integrity (P<0.001). In the study, there were no significant differences between lyophilized and fresh egg yolk extenders when comparing motility, plasma membrane integrity, acrosome integrity and DNA integrity between groups. In conclusion, lyophilized egg yolk extender provided similar cryoprotective effects with fresh egg yolk extender to cryopreserve ram semen.

Abstract
Anatolian grey cattle (endangered native Anatolian cattle) as 1 male (clone 1) and 4 females (clones 2–5) were produced from cells of 1 male and 1 female cattle by somatic cell nuclear transfer (SCNT) in a previous study. In this study, we examined the reproductive potential of these cloned animals, which are now 4 and 5 years old. The parameters evaluated by phase contrast microscopy for motility, TUNEL for DNA fragmentation, eosin staining for viability, Hoechst 33258 staining and hypo-osmotic swelling test (HOST) for membrane integrity, and fluorescein isothiocyanate-Pisum sativum agglutinin (FITC-PSA) for acrosome integrity of frozen-thawed spermatozoa, as well as birth and survival of calves following insemination with frozen-thawed semen of cloned and nuclear donor bull and normal bull. Six ejaculates and 3 samples per ejaculate from each bull were tested, and the Mann-Whitney U test was used to analyse the data. The spermatological parameters of cloned bull semen – volume, concentration, and motility of fresh – were within accepted limits for artificial insemination (4.60 ± 0.47 mL, 1.55 ± 0.21 × 109 spermatozoa mL–1, 80.00 ± 1.07%, respectively). Frozen-thawed sperm motility and viability rate were higher in the cloned bull (56.6%, 56.7%) than in its nuclear donor (47%, 43%; P < 0.05). Intact membrane and DNA fragmentation rate of cloned bull and its nuclear donor bull sperm were similar (P > 0.05) but the intact acrosome rate of cloned bull was higher than that of its nuclear donor (P < 0.05). Low rates in frozen-thawed sperm of nuclear donor can be related to storage time of sperm which were frozen 5 years before. One (clone 4) of the cloned grey heifers was artificially inseminated with frozen semen from nuclear donor bull and the other (clone 5) was naturally mated with a Holstein bull. Two healthy calves were delivered naturally. When same cloned cows (clones 4–5) and 2 other cloned heifers (clones 2–3) were artificially inseminated with frozen semen of the cloned grey bull, clones 2 and 4 gave birth to 2 healthy female calves. One cloned cow (clone 3) aborted in the third month of gestation and other one (clone 5) is currently 8 months pregnant. Two calves of clone 4 and 5 are 17 months old and 2 other calves of clone 2 and 4 are now 6 and 1 months old. Except for clone 3, our results show that cloned Anatolian grey bull and cows produced from frozen cells in gene bank have normal fertility.
