Abstract
This study aimed to select high-quality spermatozoa by sperm separation by magnetic activation of the fresh equine semen, compared to density gradient centrifugation and evaluating cell quality after selection. The semen of 10 stallions was collected by the artificial vagina technique. The samples analyzed were: (1) fresh semen; (2) density gradient centrifugation (DGC); (3) separation by magnetic activation (MASS) (nonapoptotic portion NAP); (4) separation by MASS (apoptotic portion-APT). Was analyzed: motility (light microscopy), concentration (Neubauer chamber), semen morphology (humid chamber in phase contrast), and supravital test (eosin/nigrosine). In DGC, 20 × 106 spermatozoa were used in the gradient of Percoll at 90% and 45% (400 μL each), centrifugation at 900 G/5 min, the pellet was diluted in HEPES. In MASS, 10 × 106 spermatozoa were diluted in 1.5 mL of HEPES, centrifugation at 300 G/10 min, pellet was resuspended in 150 μL of HEPES with 20 μL of nanoparticles bound to annexin V, incubation for 15 minutes and filtered in the magnetic separation column. The nonapoptotic fraction was collected directly and the apoptotic fraction after removal the column from the magnet and adding 300 μL of HEPES. The total abnormalities were 43.2% ± 2.78%, with the DGC and MASS being effective in reducing sperm abnormality by 15.6% ± 2.10% and 24.30% ± 1.63%, respectively, like the observed for the number of cells with intact membranes (50% lower in the APT portion). This nanotechnological method is efficient in producing high-quality semen samples for assisted reproduction procedures.

Abstract
Conventional in vitro fertilization is not efficacious when working with equine gametes. Although stallion spermatozoa bind to the zona pellucida in vitro, these gametes fail to initiate the acrosome reaction in the vicinity of the oocyte and cannot, therefore, penetrate into the perivitelline space. Failure of sperm penetration most likely relates to the absence of optimized in vitro fertilization media containing molecules essential to support stallion sperm capacitation. In vivo, the female reproductive tract, especially the oviductal lumen, provides an environmental milieu that appropriately regulates interactions between the gametes and promotes fertilization. Identifying these 'fertilization supporting factors' would be a great contribution for development of equine in vitro fertilization media. In this review, a description of the current understanding of the interactions stallion spermatozoa undergo during passage through the female genital tract, and related specific molecular changes that occur at the sperm plasma membrane is provided. Understanding these molecular changes may hold essential clues to achieving successful in vitro fertilization with equine gametes.

Abstract
Background Sperm selection is essential for the health of offspring conceived via assistive reproductive technology (ART). Various methods of sperm preparation for in vitro fertilization and intracytoplasmic sperm injection have been developed to acquire sperm with better quality and to avoid potential genetic disorders. However, current sperm processing and selection techniques bypass the natural selection that occurs during fertilization in vivo. The aim of this study was to present a novel distance-progesterone-combined selection approach with an original device based on the human female reproductive tract, and to report on its effectiveness based on sperm progressive motility, as well as chemotaxis. Methods A novel device with long distance channels which mimicked the female human reproductive system was designed and fabricated. This ready-to-be-used device was developed using a progesterone gradient and human tube fluid media. Sperm swam for 150 min in the device under conditions of 37 °C air temperature with 5% CO2 after separation from seminal plasma via discontinuous Percoll gradient treatment. The selected sperm were assessed for normal morphology using Diff-Quik staining. A chromatin diffusion assay assessed sperm for DNA fragments and apoptosis was assessed using annexin V-fluorescein isothiocyanate/propidium iodide fluorescent staining. Results Our distance-progesterone-combined sperm selection method was successfully established. After sperm were selected, the percentage of sperm with normal morphology increased (before vs. after selection, 11.2 ± 1.3% vs. 40.3 ± 6.6%, P = 0.000), the percentage of sperm with DNA fragmentation decreased (before vs. after selection, 15.4 ± 4.0% vs. 6.8 ± 3.3%, P = 0.001), and the percentage of sperm with apoptosis did not change significantly. Conclusions Our newly-developed method is capable of successfully selecting sperm of high quality. The method will be benefit clinical ART practice as it can reduce sperm-related genetic risks.

Abstract
Because sperm chromatin may play a key role in reproductive success, we verify the associations between sperm chromatin abnormalities, embryo development and the ability to achieve pregnancy. The evaluation of sperm chromatin maturity using aniline blue (AB), chromomycin A3 (CMA3) and toluidine blue (TB) staining were carried out in group of males from infertile couples that underwent ICSI. Low levels of sperm chromatin abnormalities (< 16%) were found in most subjects (> 50%). A higher percentage of TB-positive sperm cells were discovered in the men from couples who achieved ≤ 50% fertilized oocytes compared to men who achieved > 50%. No significant differences were discovered by the applied tests between the men from couples who achieved ≤ 50% and those who achieved > 50% high-quality embryos on the 3rd or 5th day after fertilization, nor between the men from couples who achieved pregnancy and those who failed. The sperm chromatin maturity did not correlate with the ICSI results. However, the ROC analysis revealed a significant predictive value of TB-positive spermatozoa only for fertilization. Therefore, the TB assay can be considered as a useful test for the prediction of fertilization. Our findings suggest that the level of sperm chromatin abnormalities of the examined men was not clinically significant. No found associations between sperm chromatin maturity and embryo development and the ability to achieve pregnancy. We could not exclude the effects of the repairing processes in the fertilized oocyte. The use of complementary tests that verify the status of the sperm chromatin seems justified.

Abstract
Aim: This study was aimed at evaluating the anti-apoptotic effects of Bcl-2 protein in cryopreserved buffalo bull sperm. Materials and Methods: A total 10 ejaculates from two buffalo bulls (5 each) were collected using artificial vagina method, and semen was evaluated using a standard protocol. Semen was extended by Tris egg yolk extender supplemented with Bcl-2 protein at 5, 10, and 15 µM. Semen was cryopreserved at ultra-low temperature using traditional vapor freezing method. Pre-freeze and post-thaw semen samples were evaluated for percent motility, viability, hypo-osmotic swelling test (HOST) reactive sperms; status of mitochondrial membrane activity and status of sperm phospholipase A1 and phospholipase A2 activity. Results: There were no significant effects of Bcl-2 protein supplementation on pre-freeze sperm quality. Percent motility and active mitochondria in post-thaw Bcl-2 supplemented and control groups were also similar. However, viable sperms were significantly (p<0.05) higher (74.29±4.23%) in Bcl-2 supplemented group (5 µM) as compared to control (51.6±5.77%). The proportion of HOST reactive sperms was also higher (63.1±6.73%) in Bcl-2 supplemented (5 µM) group as compared to control (50.7±6.98%). The sperm with low PLA activity (non-apoptotic) was significantly (p<0.05) higher in all the supplemented doses of Bcl-2 protein, i.e., at 5 µM (73.42±5.79%), 10 µM (75.51±6.22%), and 15 µM (74.78±5.89%) as compared to control (60.23±4.45%). We found that Bcl-2 protein supplementation at 5 µM dose improved the post-thaw semen quality indicated by higher viability, HOST reactive sperms, and sperm with low PLA activity (non-apoptotic sperms). Conclusion: Bcl-2 protein supplementation exerts its protective effect on spermatozoa against apoptosis-like changes developed during cryopreservation.

Correlation between Different Patterns of Hypo-Osmotic Swelling and Sperm Functional Tests. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2013; 7:193-8. [PMID: 24520486 PMCID: PMC3914492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/26/2012] [Accepted: 12/31/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND Sperm membrane integrity is not only important as a barrier between intra- and extra-cellular spaces, but also it can be considered as a sign of DNA integrity. Hypoosmotic swelling test reflects membrane integrity and has been used to evaluate sperm quality. Intracytoplasmic sperm injection (ICSI) in adjunct with hypo-osmotic swelling test (HOST) has been used for treatment of males with asthenozoospermia. Therefore, this study aims to evaluate correlation of different pattern of HOST with sperm parameters, protamine deficiency and apoptosis. MATERIALS AND METHODS In this case-control study, sixteen semen samples were randomly collected from infertile normozospermic men. Semen samples were divided into two portions as follows: one portion was assessed for sperm parameters according toWorld Health Organization (WHO)-2010, while the other portion, after applying HOST procedure, was used for assessment of sperm morphology, protamine deficiency and late or early apoptosis. Statistical analysis was carried out using the Statistical Package for the Social Studies (SPSS 11.5). RESULTS Our results showed that, the lowest odds ratio (OR) of abnormal sperm head morphology and abnormal acrosome was in d-sperm as compared to a-pattern or nonviable spermatozoa (p=0.00, p=0.01). In addition, a significant correlation was observed between d-sperm with sperm concentration and percentage of DNA damage (p=0.03 and p=0.04, respectively). A significant correlation was observed between percentage of sperm motility and DNA fragmentation (r=-0.56; p=0.01). Furthermore, significant correlations were observed between percentages of early apoptotic sperm with protamine deficiency and sperm concentration (p=0.009 and p=0.01, respectively). CONCLUSION Significant correlations exist between d-pattern and sperm DNA integrity. Semen samples with low sperm concentration have low percentage of d-sperm which are mature and intact sperms.
