Improvement of the in vitro fertilization and embryo development using frozen-thawed spermatozoa of microminipigs. Arch Anim Breed 2021; 64:265-271.

Abstract
This study aimed to compare the quality and the penetration
ability of frozen–thawed spermatozoa from three microminipigs and Large White
boars and to evaluate the effects of caffeine and heparin as well as the
sperm–oocyte co-incubation length on the fertilization and embryonic
development in vitro. Results showed that the fertilization rates of
spermatozoa from three microminipig boars were significantly lower than
those of a Large White boar. In the post-thaw spermatozoa from one of three
microminipig boars, the sperm quality, penetration ability, and the oocyte
development after in vitro fertilization were significantly lower than those
of the spermatozoa from other boars. The caffeine supplementation in the
fertilization media increased the rates of fertilization and blastocyst
formation for the microminipig spermatozoa with low sperm quality. In
addition to caffeine supplementation, the rates of fertilization and
blastocyst formation after using microminipig spermatozoa were significantly
higher with a 10 h sperm–oocyte co-incubation than with 3 h of
co-incubation length. Our results indicate that the differences between the
males and the breed influence the quality and fertility of frozen–thawed
boar spermatozoa. In conclusion, the presence of caffeine in the in vitro fertilization (IVF) medium
and adequate length of sperm–oocyte co-incubation may have beneficial
effects for improving IVF results when using microminipig spermatozoa with
low quality.

Abstract
Frozen-thawed boar sperm (FTS) has reduced in vitro and in vivo life span compared to liquid semen. Experiments tested whether extenders, thawing procedures, and storage temperatures could extend the fertile life span of FTS. Experiment 1 tested the effect of six extenders on postthaw motility (MOT) and viability (VIA). Straws from boars (n = 6) were thawed, diluted into each extender, and evaluated at 20, 60, and 120 minutes. There was a trend (P = 0.08) for an extender-by-time interaction for MOT and effect of extender and time for MOT (P < 0.0001) and extender (P = 0.10) and time (P < 0.0001) for VIA. Experiment 2 evaluated the effect of temperature and time of thawing on in vitro fertility at intervals after thawing. Straws (0.5 mL) from different boar ejaculates (n = 15) were thawed at 50 °C for 10, 20, or 30 seconds or at 70 °C for 5, 10, or 20 seconds and evaluated at 5, 30, and 60 minutes. There was an effect of thawing treatment on MOT, VIA, and ACR (viable sperm with intact acrosomes, P < 0.0001) and an effect of time of evaluation (P < 0.0001) on MOT and ACR. Thawing at 70 °C for 20 seconds reduced (P < 0.05) MOT, VIA, and ACR compared to other treatments. Experiment 3 tested the effects of storage temperature and time after thawing using 20 ejaculates. Samples were thawed, diluted, and allotted to storage at 17 °C, 26 °C, or 37 °C with evaluation at 2, 6, 12, and 24 hours. There was a storage temperature and time effect and an interaction for MOT and VIA (P < 0.0001). Storage at 17 °C and 26 °C increased (P < 0.05) MOT over all times (38.5%) compared to 37 °C (26%), whereas MOT was reduced at intervals. Viability was also greatest with 17 °C and 26 °C compared to 37 °C and was also affected by time and decreased with time. These results indicate that FTS can be held at 17 °C or 26 °C for up to 2 hours before use and would allow for preparation of multiple doses. These data suggest in vitro fertility of FTS is affected by extenders, thawing, and storage.

Abstract
Cryopreservation is a technique used to preserve cells for long-time storage. It is widely used in agriculture to store male gametes in liquid nitrogen. The aim of this study was to determine the optimum thawing temperature and time for samples subjected to annexin V magnetic-activated cell sorting (AnMACS) as the sperm preparation technique. Pooled semen samples from three ejaculates were divided into two groups. The treatment group was subjected both to AnMACS and to being cryopreserved, whilst the control group was cryopreserved directly without MACS. Post-thaw analysis was carried out for samples thawed at either 20°C for 13 s, 37°C for 30 s, 40°C for 7 s, 60°C for 6 s or 80°C for 5 s. Sperm kinematics, viability and capacitation status were determined for samples subjected to all thawing temperatures described. Results showed that thawing at 37°C for 13 s for MACS-processed samples was a superior option compared with other thawing procedures; there was a significant difference in P < 0.05 values for curvilinear velocity (VCL μm/s) and sperm straightness (STR %) when samples were thawed at 40°C for 7 s, with fewer capacitated spermatozoa (P < 0.05) when samples were thawed at 37°C for 30 s, 40°C for 7 s or 60°C for 6 s. Hence, we can speculate that the use of AnMACS as the sperm preparation technique can somehow enhance sperm cryosurvival rate after cryopreservation, however the fertilization potential of these cells has yet to be determined.

Abstract
Flow cytometry is now a recognized methodology within animal spermatology, and has moved from being a research tool to become routine in the assessment of animal semen destined to breeding. The availability of 'bench-top' flow cytometers and of newer and versatile markers for cell structure and function had allowed the instrumentation to measure more sperm parameters, from viability to reactiveness when exposed to exogenous stimuli, and to increase our capabilities to sort spermatozoa for potential fertilizing capacity, or chromosomal sex. The present review summarizes the state of the art regarding flow cytometry applied to animal andrology, albeit keeping an open comparative intent. It critically evaluates the present and future capabilities of flow cytometry for the diagnostics of potential fertility and for the development of current reproductive technologies such as sperm freezing, sperm selection and sperm sorting. The flow cytometry methods will probably further revolutionize our understanding of the sperm physiology and their functionality, and will undoubtedly extend its application in isolating many uncharacterized features of spermatozoa. However, continuous follow-up of the methods is a necessity owing to technical developments and the complexity of mapping spermatozoa.

Abstract
The objective of the present study was to determine the effects of docosahexaenoic acid (DHA)-enriched hen egg yolks and L-cysteine supplementation on the qualities of the cryopreserved boar semen. A total of 15 ejaculates from 5 Pietrain boars were divided into 4 groups according to the compositions of the freezing extenders used, that is, normal hen egg yolk (group I), DHA-enriched hen egg yolk (group II), normal hen egg yolk with 5 mmol L(-1) of cysteine supplementation (group III) and DHA-enriched hen egg yolk with 5 mmol L(-1) of cysteine supplementation (group IV). The semen was cryopreserved using controlled rate freezer and was thawed at 50 degrees C for 12 s. Progressive motility, sperm viability, acrosome integrity and functional integrity of sperm plasma membrane of the post-thawed semen were evaluated. The supplementation of L-cysteine in the freezing extender alone (group III) improved progressive motility (P < 0.05), and the supplementation of L-cysteine in combination with DHA-enriched hen egg yolk (group IV) improved both progressive motility (P < 0.05) and acrosome integrity (P < 0.01). The use of DHA-enriched hen egg yolk alone (group II) did not enhance any of the post-thawed semen qualities (P > 0.05). In conclusion, the supplementation of antioxidant L-cysteine alone or in combination with DHA-enriched hen egg yolk significantly improved the post-thawed semen qualities, especially progressive motility and acrosome integrity.

Abstract
A modified protocol of neutral comet assay was utilized to assess the effect of low density lipoprotein (LDL) on the DNA integrity of boar freezing-thawing semen. The results demonstrated that the method was high sensitive and easier manipulation and LDL significantly protected sperm DNA integrity (p<0.05) from the damage caused by cryopreservation except TD at the concentration of 6%, 7% and TM at 6%, the optimal LDL concentration in diluents was 9%. Moreover, LDL showed better protection in 0.25 ml than in 0.5 ml types of straw (p<0.05) and no difference was observed in the same volume straw at the concentration of 9% and 10%. It was just the same for LDL effect on boar sperm DNA in cryopreservation 0 day and 30 days (p>0.05).

Abstract
The effect of lactose and glycerol concentration, as well as the equilibration time with glycerol was studied on motility, normal apical ridge (NAR), and chromatin state of boar spermatozoa after the freezing and thawing process. In the first experiment, samples were frozen in first and second extenders containing different concentrations of lactose (11, 12 and 14%). In the second experiment samples were frozen using second extenders with different concentrations of glycerol (4, 6, 8 and 10%) and were incubated at 5 degrees C for 0 and 30 min. Motility, motility after caffeine treatment, NAR, chromatin condensation and stability (susceptibility to de-condense after heparin treatment) were evaluated. The results indicated that freezing spermatozoa in extenders with increasing concentrations of lactose adversely affected motility but provided a protective effect on acrosomes. Increased lactose concentration induced higher chromatin condensation but maintained the same stability. Increasing the glycerol concentration in the second extender from 4-6 to 8% led to higher motility and NAR as well as lower chromatin condensation and stability. When 30 min equilibration time was allowed after dilution with the same extenders, spermatozoa showed higher NAR and lower chromatin condensation and stability. The longer equilibration time was detrimental for motility when freezing in the 8% glycerol extender but favourable when using the 4% glycerol extender. Compared to the 8% glycerol, spermatozoa frozen in the 10% glycerol extender showed similar motility and increased chromatin condensation and stability, as well as low values of NAR that did not improve by longer incubation time.

Abstract
Spermatozoa from some boars sustain the process of cryopreservation poorly and yield poor fertility after artificial insemination. Poor freezability has not been disclosed using conventional semen analyses. A defective chromatin can, if present in a substantial number of spermatozoa, affect the fertilizing ability of spermatozoa. Here we tested the hypothesis that nuclear DNA instability could explain differences in freezability among boars, and complement or supersede conventional tests for sperm quality such as sperm motility or membrane assessments. Frozen-thawed (FT) spermatozoa from a total of 44 stud boars were assessed by the sperm chromatin structure assay (SCSA), in relation to computer-assisted sperm analysis-derived sperm motility variables and sperm viability (triple fluorescent microscopic staining), including three experiments. The first trial, including 24 boars, evaluated the relationship between the sperm motility and viability with levels of DNA integrity. The SCSA showed that most spermatozoa had intact DNA [levels of DNA fragmentation index (%DFI) ranging from 0.63% to 11.85%] significantly correlated (albeit weakly) with current sperm quality variables. The second trial, on 15 boars, assessed the influence of two different thawing rates (20 s at 37 degrees C vs. 8 s at 70 degrees C) and the post-thaw incubation times (0, 30, 150 and 300 min) at 37 degrees C on FT-boar sperm quality. The highest sperm survival (p < 0.05) and the lowest DNA damage (p < 0.01) were achieved when thawing was carried out at 70 degrees C for 8 s, without any change during the first 150 min of incubation. Finally, the third experiment studied if differences in sperm freezability showed by stud boar semen, as 'good' or 'bad' freezers by conventional analyses, could be attributed to differences in chromatin structure. All SCSA parameters were low, but significantly (p < 0.05-0.001) higher for 'bad' freezers, showing they had less homogeneous sperm chromatin than the 'good' freezers. The results indicate that SCSA outcome complements conventional assessment of FT-boar spermatozoa, disclosing differences in their ability to sustain freezing and thawing. However, the low overall DNA damage observed in FT spermatozoa seems to have poor biological significance.
