Archana SS, Swathi D, Ramya L, Heena HS, Krishnappa B, Binsila BK, Rajendran D, Selvaraju S. Relationship among seminal antigenicity, antioxidant status and metabolically active sperm from Holstein-Friesian ( Bos taurus) bulls. Syst Biol Reprod Med 2023; 69:366-378. [PMID: 37225677 DOI: 10.1080/19396368.2023.2198070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 02/13/2023] [Accepted: 02/20/2023] [Indexed: 05/26/2023]
Abstract
Sperm antigenicity has been implicated as a regulatory factor for acquiring fertilizing competence in the female reproductive tract. Overt immune response against the sperm proteins leads to idiopathic infertility. Hence, the aim of the study was to evaluate the influence of the auto-antigenic potential of sperm on the antioxidant status, metabolic activities and reactive oxygen species (ROS) in bovine. Semen from Holstein-Friesian bulls (n = 15) was collected and classified into higher (HA, n = 8) and lower (LA, n = 7) antigenic groups based on micro-titer agglutination assay. The neat semen was subjected to the evaluation of bacterial load, leukocyte count, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and lipid peroxidation (LPO) levels. Antioxidant activities in seminal plasma and intracellular ROS levels in the post-thawed sperm were estimated. The number of leukocytes was lower (p < .05) in the HA than the LA semen. The percentage of metabolically active sperm was higher (p < .05) in HA than the LA group. The activities of total non-enzymatic antioxidant, superoxide dismutase (SOD) and catalase (CAT) were higher (p < .05) while glutathione peroxidase activity was lower (p < .05) in the seminal plasma of LA group. The LPO levels of neat sperm and the percentage sperm positive for intracellular ROS in the cryopreserved sample were lower (p < .05) in the HA group. Auto-antigenic levels were positively correlated with the percentage of metabolically active sperm (r = 0.73, p < .01). However, the seminal auto-antigenicity was negatively (p < .05) correlated with the levels of SOD (r=-0.66), CAT (r=-0.72), LPO (r=-0.602) and intracellular ROS (r=-0.835). The findings were represented in graphical abstract. It is inferred that the higher auto-antigenic levels protect the quality of bovine semen by promoting sperm metabolism and lowering ROS and LPO levels.

Abstract
The male reproductive system, particularly the male gamete, offers a unique barrier to the immune system. The growing germ cells in the testis need to be shielded from autoimmune damage. Hence the testis has to establish and sustain an immune-privileged milieu. Sertoli cells create this safe space, protected by the blood-testis barrier. Cytokines are a type of immune reaction that can positively and negatively affect male reproductive health. Inflammation, disease, and obesity are just a few physiological conditions for which cytokines mediate signals. They interact with steroidogenesis, shaping the adrenals and testes to produce the hormones needed for survival. In particular pathological condition, including autoimmune disorders, contains high levels of the same cytokines in semen that play an essential role in the immunomodulation of the male gonad. This review focuses on understanding the immunological role of cytokines in the control and development of male reproduction. Also, in maintaining male reproductive health and diseases linked with their aberrant function in the testis.

Abstract
We aimed at the evaluating the occurrence of macrophages in rabbit semen and finding possible relationship between macrophage concentration and spermatozoa quality. The concentration of macrophages in semen samples from broiler rabbit males of lines M91 and P91 (n = 30) without overt evidence of genital tract infections was determined using monocyte/macrophage lineage antigen CD14 and flow cytometry. Then the rabbits were assigned into three groups according to the macrophage concentration in semen (MΦ1 group with less than 1 × 106 macrophages/mL, MΦ2 group with 1.5-3.5 × 106 macrophages/mL and MΦ3 group with more than 8 × 106 macrophages/mL). Spermatozoa viability parameters such as occurrence of apoptotic (Yo-Pro-1) and dead/necrotic (propidium iodide) spermatozoa and plasma membrane integrity (PNA-Fluos) were evaluated using flow cytometry. Sperm motility parameters were determined by CASA (Computer Assisted Semen Analysis). Ultrastructural detection of macrophages was performed using transmission electron microscopy. Spermatozoa fertility potential was examined after intravaginal artificial insemination of rabbit doses. Significantly higher proportions of the apoptotic and necrotic spermatozoa and spermatozoa with lower plasma membrane integrity were revealed in the MΦ3 group compared to MΦ1 and MΦ2 groups. The percentage value of total motility and progressive movement was significantly highest in the MΦ1 group, whilst lowest in the MΦ3 group. The conception rate and the kindling rate were significantly decreased in the group with the highest macrophage concentration (MΦ3). Based on our results we can conclude that the abundance of seminal macrophages in the rabbit semen may be closely associated with poor spermatozoa quality.

Abstract
A large body of evidence points to the existence of a close, dynamic relationship between the immune system and the male reproductive tract, which has important implications for our understanding of both systems. The testis and the male reproductive tract provide an environment that protects the otherwise highly immunogenic spermatogenic cells and sperm from immunological attack. At the same time, secretions of the testis, including androgens, influence the development and mature functions of the immune system. Activation of the immune system has negative effects on both androgen and sperm production, so that systemic or local infection and inflammation compromise male fertility. The mechanisms underlying these interactions have begun to receive the attention from reproductive biologists and immunologists that they deserve, but many crucial details remain to be uncovered. A complete picture of male reproductive tract function and its response to toxic agents is contingent upon continued exploration of these interactions and the mechanisms involved.

Abstract
The heme protein myeloperoxidase is released from stimulated polymorphonuclear leukocytes, a cell species found in increasing amounts in the male and female genital tract of patients with genital tract inflammations. Myeloperoxidase binds only to a fraction of freshly prepared human spermatozoa. The number of spermatozoa able to bind myeloperoxidase raised considerably in samples containing pre-damaged cells or in acrosome-reacted samples. In addition, myeloperoxidase released from zymosan-stimulated polymorphonuclear leukocytes was also able to bind to pre-damaged spermatozoa. The ability of spermatozoa to bind myeloperoxidase coincided with the binding of annexin V to externalized phosphatidylserine epitopes indicating the loss of plasma membrane integrity and with the incorporation of ethidium homodimer I. Myeloperoxidase did not interact with intact spermatozoa. Annexin V and myeloperoxidase bind to the same binding sites as verified by double fluorescence techniques, flowcytometry analyses as well as competition experiments. We demonstrated also that myeloperoxidase is eluted together with pure phosphatidylserine liposomes or liposomes composed of phosphatidylserine and phosphatidylcholine in gel filtration, but not with pure phosphatidylcholine liposomes. In conclusion, myeloperoxidase interacts with apoptotic spermatozoa via binding to externalized phosphatidylserine indicating a yet unknown role of this protein in recognition and removal of apoptotic cells during inflammation.

Abstract
Oxidative stress occurs when the production of potentially destructive reactive oxygen species (ROS) exceeds the bodies own natural antioxidant defenses, resulting in cellular damage. Oxidative stress is a common pathology seen in approximately half of all infertile men. ROS, defined as including oxygen ions, free radicals and peroxides are generated by sperm and seminal leukocytes within semen and produce infertility by two key mechanisms. First, they damage the sperm membrane, decreasing sperm motility and its ability to fuse with the oocyte. Second, ROS can alter the sperm DNA, resulting in the passage of defective paternal DNA on to the conceptus. This review will provide an overview of oxidative biochemistry related to sperm health and will identify which men are most at risk of oxidative infertility. Finally, the review will outline methods available for diagnosing oxidative stress and the various treatments available.

Abstract
Although much has been reported on the in vitro interaction of Chlamydia trachomatis with cells derived from the female genital tract, little is known of its interaction with male genital tract epithelium. The aim of this work was to investigate the effect of C. trachomatis serovar E on immortalized normal human urethral epithelial cells and on immortalized normal adult human prostate epithelial cells with regard to chlamydial growth and secretion of cytokines. After infection, these epithelial cells were assessed for their support of chlamydial growth in comparison with HeLa cells, and cytokine levels in cell culture supernatants were determined by ELISA. Although the male-derived epithelial cells supported growth of chlamydiae, the best growth was seen in HeLa cells. In contrast to prostate epithelial cells, the urethral epithelial cells released much larger quantities of interleukin 1alpha (IL-1alpha) following infection, whereas both IL-6 and IL-8 were produced in larger quantities by infected prostate cells. At 7 days post-infection, HeLa cells consistently produced large quantities of all three cytokines. In conclusion, the male-derived cell lines were shown to support the invasion of C. trachomatis and initiate a proinflammatory response to infection. From in vitro studies the suggestion that high levels of IL-6 could be a possible marker for chlamydial prostatitis is confirmed. Although not as marked a change, it is also suggested that higher IL-8 levels could be associated more with infection of the prostate than the urethra. Differential cytokine production by different male-derived epithelial cells could help determine the site of chlamydial infection and help in the study of pathogenesis.

Abstract
The aim of this study was to evaluate the effects of tumour necrosis factor-alpha (TNF-alpha) on sperm motility, mitochondrial membrane potential (DeltaPsi), phosphatidylserine (PS) externalization, sperm chromatin packaging quality, and DNA fragmentation. Motile spermatozoa, obtained from 10 normozoospermic men, were incubated with increasing concentrations of TNF-alpha and analyzed 1, 3, 6, and 24 h after incubation by flow cytometry. TNF-alpha decreased total motility 24 h after incubation at 10 ng/mL and progressive motility 3 h after incubation. Accordingly, TNF-alpha reduced sperm DeltaPsi in a concentration- and time-dependent manner. TNF-alpha increased the percentage of spermatozoa with PS externalization from the concentration of 1 ng/mL 1 h after incubation. TNF-alpha produced sperm chromatin and DNA damage in a concentration- and time-dependent manner. In conclusion, these findings may explain the reduction of fertility, secondary to upregulated production of TNF-alpha, in men with urogenital infections.

Abstract
OBJECTIVE To investigate the correlation between leukocytospermia, bacteriospermia, and clinical signs of infection and to evaluate antiinflammatory therapy. DESIGN Prospective nonrandomized study. SETTING Andrologic clinic at university hospital. PATIENT(S) A total of 56 patients were evaluated, and 12 of them received further treatment with a Cox-2 inhibitor. INTERVENTION(S) Semen analysis and clinical investigation were done according to World Health Organization guidelines. Serum levels of leukocytes, C-reactive protein (CRP), and prostate-specific antigen (PSA) were measured from blood samples. MAIN OUTCOME MEASURE(S) Sperm concentration, leukocyte concentration, serum leukocyte count, CRP, PSA, bacterial growth. RESULT(S) Leukocytospermia (>1 x 10(6)/mL) was present in 60.7% of the semen samples, significant pathogenic bacterial growth was detectable in 35.7%, and 14.3% of the samples fulfilled the criteria for ejaculate signs of infection. All serum parameters were within the normal range. In abacterial leukocytospermia, treatment with a Cox-2 inhibitor decreased leukocytospermia from 5.5 x 10(6)/mL to 1.0 x 10(6)/mL (P=.001) and increased sperm concentration from 22.5 x 10(6)/mL to 48.0 x 10(6)/mL (P=.02). CONCLUSION(S) There was no evidence of an immune response in the peripheral blood system. In abacterial leukocytospermia, treatment with a Cox-2 inhibitor seems to be able to reduce leukocytospermia and increase sperm count.

Abstract
Leucocytospermia is usually associated with genito-urinary tract infections and its role on male infertility is currently under debate. The aim of this study was to investigate the relationship between leucocytospermia and seminal fluid alterations in men with fertility problems. We evaluated 40 consecutive spemiograms of leucocystospermic men, and another 40 from individuals without leucocytospermia, with regard to age, number, motility and sperm morphology, and presence of genito-urinary tract infections. There was a significant difference in terms of motility (23.27% in non-leucocytospermic pts vs. 15.57% in leucocytospermic pts., p=0.0034). Furthermore, asthenozoospermia was more frequent in leucocytospermic pts (45% vs. 72.,%, p=0.0231), as also teratozoospermia (32.5% vs. 62.5%, p=0.0138). The probability to have at least one of the major seminal alterations was greater in leucocytospermic pts (75.3% vs. 52.5%, p=0.0048). The incidence of infections in leucocytospermic group was 13%. Our study underlines the relationship between leucocytospermia, motility, and normal morphology reduction in human semen. These data might suggest the presence of a damage due to the ROS produced by seminal leucocytes on spermatozoa. Our analysis wants to emphasize the need to treat this condition, with special regard to the frequent use of PMA procedures.
